Camera.Parameters

extends Object
java.lang.Object
   ↳ android.hardware.Camera.Parameters

This class was deprecated in API level 21.
We recommend using the new android.hardware.camera2 API for new applications.

Class Overview

Camera service settings.

To make camera parameters take effect, applications have to call setParameters(Camera.Parameters). For example, after setWhiteBalance(String) is called, white balance is not actually changed until setParameters(Camera.Parameters) is called with the changed parameters object.

Different devices may have different camera capabilities, such as picture size or flash modes. The application should query the camera capabilities before setting parameters. For example, the application should call getSupportedColorEffects() before calling setColorEffect(String). If the camera does not support color effects, getSupportedColorEffects() will return null.

Constant Value: "auto"

public static final String FOCUS_MODE_CONTINUOUS_PICTURE

Added in API level 14

Continuous auto focus mode intended for taking pictures. The camera continuously tries to focus. The speed of focus change is more aggressive than FOCUS_MODE_CONTINUOUS_VIDEO. Auto focus starts when the parameter is set.

Applications can call autoFocus(AutoFocusCallback) in this mode. If the autofocus is in the middle of scanning, the focus callback will return when it completes. If the autofocus is not scanning, the focus callback will immediately return with a boolean that indicates whether the focus is sharp or not. The apps can then decide if they want to take a picture immediately or to change the focus mode to auto, and run a full autofocus cycle. The focus position is locked after autoFocus call. If applications want to resume the continuous focus, cancelAutoFocus must be called. Restarting the preview will not resume the continuous autofocus. To stop continuous focus, applications should change the focus mode to other modes.

Constant Value: "continuous-picture"

public static final String FOCUS_MODE_CONTINUOUS_VIDEO

Added in API level 9

Continuous auto focus mode intended for video recording. The camera continuously tries to focus. This is the best choice for video recording because the focus changes smoothly . Applications still can call takePicture(Camera.ShutterCallback, Camera.PictureCallback, Camera.PictureCallback) in this mode but the subject may not be in focus. Auto focus starts when the parameter is set.

Since API level 14, applications can call autoFocus(AutoFocusCallback) in this mode. The focus callback will immediately return with a boolean that indicates whether the focus is sharp or not. The focus position is locked after autoFocus call. If applications want to resume the continuous focus, cancelAutoFocus must be called. Restarting the preview will not resume the continuous autofocus. To stop continuous focus, applications should change the focus mode to other modes.

Constant Value: "continuous-video"

public boolean getAutoExposureLock ()

Added in API level 14

Gets the state of the auto-exposure lock. Applications should check isAutoExposureLockSupported() before using this method. See setAutoExposureLock(boolean) for details about the lock.

Returns
boolean State of the auto-exposure lock. Returns true if auto-exposure is currently locked, and false otherwise.

public boolean getAutoWhiteBalanceLock ()

Added in API level 14

Gets the state of the auto-white balance lock. Applications should check isAutoWhiteBalanceLockSupported() before using this method. See setAutoWhiteBalanceLock(boolean) for details about the lock.

Returns
boolean State of the auto-white balance lock. Returns true if auto-white balance is currently locked, and false otherwise.

public String getColorEffect ()

Added in API level 5

Gets the current color effect setting.

Returns
String current color effect. null if color effect setting is not supported.

public int getExposureCompensation ()

Added in API level 8

Gets the current exposure compensation index.

Returns
int current exposure compensation index. The range is getMinExposureCompensation() to getMaxExposureCompensation(). 0 means exposure is not adjusted.

public float getExposureCompensationStep ()

Added in API level 8

Gets the exposure compensation step.

Returns
float exposure compensation step. Applications can get EV by multiplying the exposure compensation index and step. Ex: if exposure compensation index is -6 and step is 0.333333333, EV is -2.

public String getFlashMode ()

Added in API level 5

Gets the current flash mode setting.

Returns
String current flash mode. null if flash mode setting is not supported.

public float getFocalLength ()

Added in API level 8

Gets the focal length (in millimeter) of the camera.

Returns
float the focal length. This method will always return a valid value.

public List<Camera.Area> getFocusAreas ()

Added in API level 14

Gets the current focus areas. Camera driver uses the areas to decide focus.

Before using this API or setFocusAreas(List), apps should call getMaxNumFocusAreas() to know the maximum number of focus areas first. If the value is 0, focus area is not supported.

Each focus area is a rectangle with specified weight. The direction is relative to the sensor orientation, that is, what the sensor sees. The direction is not affected by the rotation or mirroring of setDisplayOrientation(int). Coordinates of the rectangle range from -1000 to 1000. (-1000, -1000) is the upper left point. (1000, 1000) is the lower right point. The width and height of focus areas cannot be 0 or negative.

The weight must range from 1 to 1000. The weight should be interpreted as a per-pixel weight - all pixels in the area have the specified weight. This means a small area with the same weight as a larger area will have less influence on the focusing than the larger area. Focus areas can partially overlap and the driver will add the weights in the overlap region.

A special case of a null focus area list means the driver is free to select focus targets as it wants. For example, the driver may use more signals to select focus areas and change them dynamically. Apps can set the focus area list to null if they want the driver to completely control focusing.

Focus areas are relative to the current field of view (getZoom()). No matter what the zoom level is, (-1000,-1000) represents the top of the currently visible camera frame. The focus area cannot be set to be outside the current field of view, even when using zoom.

Focus area only has effect if the current focus mode is FOCUS_MODE_AUTO, FOCUS_MODE_MACRO, FOCUS_MODE_CONTINUOUS_VIDEO, or FOCUS_MODE_CONTINUOUS_PICTURE.

Returns
List<Camera.Area> a list of current focus areas

public void getFocusDistances (float[] output)

Added in API level 9

Gets the distances from the camera to where an object appears to be in focus. The object is sharpest at the optimal focus distance. The depth of field is the far focus distance minus near focus distance.

Focus distances may change after calling autoFocus(AutoFocusCallback), cancelAutoFocus(), or startPreview(). Applications can call getParameters() and this method anytime to get the latest focus distances. If the focus mode is FOCUS_MODE_CONTINUOUS_VIDEO, focus distances may change from time to time.

This method is intended to estimate the distance between the camera and the subject. After autofocus, the subject distance may be within near and far focus distance. However, the precision depends on the camera hardware, autofocus algorithm, the focus area, and the scene. The error can be large and it should be only used as a reference.

Far focus distance >= optimal focus distance >= near focus distance. If the focus distance is infinity, the value will be Float.POSITIVE_INFINITY.

Parameters
output focus distances in meters. output must be a float array with three elements. Near focus distance, optimal focus distance, and far focus distance will be filled in the array.

public String getFocusMode ()

Added in API level 5

Gets the current focus mode setting.

Returns
String current focus mode. This method will always return a non-null value. Applications should call autoFocus(AutoFocusCallback) to start the focus if focus mode is FOCUS_MODE_AUTO or FOCUS_MODE_MACRO.

Returns
int maximum exposure compensation index (>=0). If both this method and getMinExposureCompensation() return 0, exposure compensation is not supported.

public int getMaxNumDetectedFaces ()

Added in API level 14

Gets the maximum number of detected faces supported. This is the maximum length of the list returned from Camera.FaceDetectionListener. If the return value is 0, face detection of the specified type is not supported.

Returns
int the maximum number of detected face supported by the camera.

public int getMaxNumFocusAreas ()

Added in API level 14

Gets the maximum number of focus areas supported. This is the maximum length of the list in setFocusAreas(List) and getFocusAreas().

Returns
int the maximum number of focus areas supported by the camera.

See also:

public int getMaxNumMeteringAreas ()

Added in API level 14

Gets the maximum number of metering areas supported. This is the maximum length of the list in setMeteringAreas(List) and getMeteringAreas().

Returns
int the maximum number of metering areas supported by the camera.

See also:

public int getMaxZoom ()

Added in API level 8

Gets the maximum zoom value allowed for snapshot. This is the maximum value that applications can set to setZoom(int). Applications should call isZoomSupported() before using this method. This value may change in different preview size. Applications should call this again after setting preview size.

Returns
int the maximum zoom value supported by the camera.

public List<Camera.Area> getMeteringAreas ()

Added in API level 14

Gets the current metering areas. Camera driver uses these areas to decide exposure.

Before using this API or setMeteringAreas(List), apps should call getMaxNumMeteringAreas() to know the maximum number of metering areas first. If the value is 0, metering area is not supported.

Each metering area is a rectangle with specified weight. The direction is relative to the sensor orientation, that is, what the sensor sees. The direction is not affected by the rotation or mirroring of setDisplayOrientation(int). Coordinates of the rectangle range from -1000 to 1000. (-1000, -1000) is the upper left point. (1000, 1000) is the lower right point. The width and height of metering areas cannot be 0 or negative.

The weight must range from 1 to 1000, and represents a weight for every pixel in the area. This means that a large metering area with the same weight as a smaller area will have more effect in the metering result. Metering areas can partially overlap and the driver will add the weights in the overlap region.

A special case of a null metering area list means the driver is free to meter as it chooses. For example, the driver may use more signals to select metering areas and change them dynamically. Apps can set the metering area list to null if they want the driver to completely control metering.

Metering areas are relative to the current field of view (getZoom()). No matter what the zoom level is, (-1000,-1000) represents the top of the currently visible camera frame. The metering area cannot be set to be outside the current field of view, even when using zoom.

No matter what metering areas are, the final exposure are compensated by setExposureCompensation(int).

Returns
List<Camera.Area> a list of current metering areas

public int getMinExposureCompensation ()

Added in API level 8

Camcorder applications should set the preview size to a value that is not larger than the preferred preview size. In other words, the product of the width and height of the preview size should not be larger than that of the preferred preview size. In addition, we recommend to choose a preview size that has the same aspect ratio as the resolution of video to be recorded.

Returns
Camera.Size the preferred preview size (width and height) in pixels for video recording if getSupportedVideoSizes() does not return null; otherwise, null is returned.

public List<int[]> getSupportedPreviewFpsRange ()

Added in API level 9

Gets the supported preview fps (frame-per-second) ranges. Each range contains a minimum fps and maximum fps. If minimum fps equals to maximum fps, the camera outputs frames in fixed frame rate. If not, the camera outputs frames in auto frame rate. The actual frame rate fluctuates between the minimum and the maximum. The values are multiplied by 1000 and represented in integers. For example, if frame rate is 26.623 frames per second, the value is 26623.

public List<Integer> getZoomRatios ()

Added in API level 8

Gets the zoom ratios of all zoom values. Applications should check isZoomSupported() before using this method.

Returns
List<Integer> the zoom ratios in 1/100 increments. Ex: a zoom of 3.2x is returned as 320. The number of elements is getMaxZoom() + 1. The list is sorted from small to large. The first element is always 100. The last element is the zoom ratio of the maximum zoom value.

public boolean isAutoExposureLockSupported ()

Added in API level 14

Returns true if auto-exposure locking is supported. Applications should call this before trying to lock auto-exposure. See setAutoExposureLock(boolean) for details about the lock.

Returns
boolean true if auto-exposure lock is supported.

public boolean isAutoWhiteBalanceLockSupported ()

Added in API level 14

Returns true if auto-white balance locking is supported. Applications should call this before trying to lock auto-white balance. See setAutoWhiteBalanceLock(boolean) for details about the lock.

Returns
boolean true if auto-white balance lock is supported.

public boolean isSmoothZoomSupported ()

Added in API level 8

Returns true if smooth zoom is supported. Applications should call this before using other smooth zoom methods.

Returns
boolean true if smooth zoom is supported.

public boolean isVideoSnapshotSupported ()

Added in API level 14

Returns true if video snapshot is supported. That is, applications can call takePicture(Camera.ShutterCallback, Camera.PictureCallback, Camera.PictureCallback, Camera.PictureCallback) during recording. Applications do not need to call startPreview() after taking a picture. The preview will be still active. Other than that, taking a picture during recording is identical to taking a picture normally. All settings and methods related to takePicture work identically. Ex: getPictureSize(), getSupportedPictureSizes(), setJpegQuality(int), setRotation(int), and etc. The picture will have an EXIF header. FLASH_MODE_AUTO and FLASH_MODE_ON also still work, but the video will record the flash.

Applications can set shutter callback as null to avoid the shutter sound. It is also recommended to set raw picture and post view callbacks to null to avoid the interrupt of preview display.

Field-of-view of the recorded video may be different from that of the captured pictures. The maximum size of a video snapshot may be smaller than that for regular still captures. If the current picture size is set higher than can be supported by video snapshot, the picture will be captured at the maximum supported size instead.

Returns
boolean true if video snapshot is supported.

public boolean isVideoStabilizationSupported ()

Added in API level 15

Returns true if video stabilization is supported. See setVideoStabilization(boolean) for details of video stabilization.

Returns
boolean true if video stabilization is supported

See also:

public void setAutoExposureLock (boolean toggle)

Added in API level 14

Sets the auto-exposure lock state. Applications should check isAutoExposureLockSupported() before using this method.

If set to true, the camera auto-exposure routine will immediately pause until the lock is set to false. Exposure compensation settings changes will still take effect while auto-exposure is locked.

If auto-exposure is already locked, setting this to true again has no effect (the driver will not recalculate exposure values).

Stopping preview with stopPreview(), or triggering still image capture with takePicture(Camera.ShutterCallback, Camera.PictureCallback, Camera.PictureCallback), will not change the lock.

Exposure compensation, auto-exposure lock, and auto-white balance lock can be used to capture an exposure-bracketed burst of images, for example.

Auto-exposure state, including the lock state, will not be maintained after camera release() is called. Locking auto-exposure after open() but before the first call to startPreview() will not allow the auto-exposure routine to run at all, and may result in severely over- or under-exposed images.

Parameters
toggle new state of the auto-exposure lock. True means that auto-exposure is locked, false means that the auto-exposure routine is free to run normally.

public void setAutoWhiteBalanceLock (boolean toggle)

Added in API level 14

Sets the auto-white balance lock state. Applications should check isAutoWhiteBalanceLockSupported() before using this method.

If set to true, the camera auto-white balance routine will immediately pause until the lock is set to false.

If auto-white balance is already locked, setting this to true again has no effect (the driver will not recalculate white balance values).

Stopping preview with stopPreview(), or triggering still image capture with takePicture(Camera.ShutterCallback, Camera.PictureCallback, Camera.PictureCallback), will not change the the lock.

Changing the white balance mode with setWhiteBalance(String) will release the auto-white balance lock if it is set.

Exposure compensation, AE lock, and AWB lock can be used to capture an exposure-bracketed burst of images, for example. Auto-white balance state, including the lock state, will not be maintained after camera release() is called. Locking auto-white balance after open() but before the first call to startPreview() will not allow the auto-white balance routine to run at all, and may result in severely incorrect color in captured images.

Parameters
toggle new state of the auto-white balance lock. True means that auto-white balance is locked, false means that the auto-white balance routine is free to run normally.

public void setColorEffect (String value)

Added in API level 5

See also:

public void setPictureSize (int width, int height)

Added in API level 1

Sets the dimensions for pictures.

Applications need to consider the display orientation. See setPreviewSize(int, int) for reference.

Parameters
width the width for pictures, in pixels
height the height for pictures, in pixels

public void setPreviewFormat (int pixel_format)

Added in API level 1

Sets the image format for preview pictures.

If this is never called, the default format will be NV21, which uses the NV21 encoding format.

Use getSupportedPreviewFormats() to get a list of the available preview formats.

It is strongly recommended that either NV21 or YV12 is used, since they are supported by all camera devices.

For YV12, the image buffer that is received is not necessarily tightly packed, as there may be padding at the end of each row of pixel data, as described in YV12. For camera callback data, it can be assumed that the stride of the Y and UV data is the smallest possible that meets the alignment requirements. That is, if the preview size is width x height, then the following equations describe the buffer index for the beginning of row y for the Y plane and row c for the U and V planes:

 yStride   = (int) ceil(width / 16.0) * 16;
 uvStride  = (int) ceil( (yStride / 2) / 16.0) * 16;
 ySize     = yStride * height;
 uvSize    = uvStride * height / 2;
 yRowIndex = yStride * y;
 uRowIndex = ySize + uvSize + uvStride * c;
 vRowIndex = ySize + uvStride * c;
 size      = ySize + uvSize * 2;

Parameters
pixel_format the desired preview picture format, defined by one of the ImageFormat constants. (E.g., ImageFormat.NV21 (default), or ImageFormat.YV12)

public void setPreviewFpsRange (int min, int max)

Added in API level 9

Sets the minimum and maximum preview fps. This controls the rate of preview frames received in Camera.PreviewCallback. The minimum and maximum preview fps must be one of the elements from getSupportedPreviewFpsRange().

Parameters
min the minimum preview fps (scaled by 1000).
max the maximum preview fps (scaled by 1000).
Throws
RuntimeException if fps range is invalid.

public void setPreviewFrameRate (int fps)

Added in API level 1

This method was deprecated in API level 9.
replaced by setPreviewFpsRange(int, int)

Sets the rate at which preview frames are received. This is the target frame rate. The actual frame rate depends on the driver.

Parameters
fps the frame rate (frames per second)

public void setPreviewSize (int width, int height)

Added in API level 1

Sets the dimensions for preview pictures. If the preview has already started, applications should stop the preview first before changing preview size. The sides of width and height are based on camera orientation. That is, the preview size is the size before it is rotated by display orientation. So applications need to consider the display orientation while setting preview size. For example, suppose the camera supports both 480x320 and 320x480 preview sizes. The application wants a 3:2 preview ratio. If the display orientation is set to 0 or 180, preview size should be set to 480x320. If the display orientation is set to 90 or 270, preview size should be set to 320x480. The display orientation should also be considered while setting picture size and thumbnail size.

Parameters
width the width of the pictures, in pixels
height the height of the pictures, in pixels

public void setRecordingHint (boolean hint)

Added in API level 14

Sets recording mode hint. This tells the camera that the intent of the application is to record videos start(), not to take still pictures takePicture(Camera.ShutterCallback, Camera.PictureCallback, Camera.PictureCallback, Camera.PictureCallback). Using this hint can allow MediaRecorder.start() to start faster or with fewer glitches on output. This should be called before starting preview for the best result, but can be changed while the preview is active. The default value is false. The app can still call takePicture() when the hint is true or call MediaRecorder.start() when the hint is false. But the performance may be worse.

Parameters
hint true if the apps intend to record videos using MediaRecorder.

public void setRotation (int rotation)

Added in API level 5

Sets the clockwise rotation angle in degrees relative to the orientation of the camera. This affects the pictures returned from JPEG Camera.PictureCallback. The camera driver may set orientation in the EXIF header without rotating the picture. Or the driver may rotate the picture and the EXIF thumbnail. If the Jpeg picture is rotated, the orientation in the EXIF header will be missing or 1 (row #0 is top and column #0 is left side).

If applications want to rotate the picture to match the orientation of what users see, apps should use OrientationEventListener and Camera.CameraInfo. The value from OrientationEventListener is relative to the natural orientation of the device. CameraInfo.orientation is the angle between camera orientation and natural device orientation. The sum of the two is the rotation angle for back-facing camera. The difference of the two is the rotation angle for front-facing camera. Note that the JPEG pictures of front-facing cameras are not mirrored as in preview display.

For example, suppose the natural orientation of the device is portrait. The device is rotated 270 degrees clockwise, so the device orientation is 270. Suppose a back-facing camera sensor is mounted in landscape and the top side of the camera sensor is aligned with the right edge of the display in natural orientation. So the camera orientation is 90. The rotation should be set to 0 (270 + 90).

The reference code is as follows.

 public void onOrientationChanged(int orientation) {
     if (orientation == ORIENTATION_UNKNOWN) return;
     android.hardware.Camera.CameraInfo info =
            new android.hardware.Camera.CameraInfo();
     android.hardware.Camera.getCameraInfo(cameraId, info);
     orientation = (orientation + 45) / 90 * 90;
     int rotation = 0;
     if (info.facing == CameraInfo.CAMERA_FACING_FRONT) {
         rotation = (info.orientation - orientation + 360) % 360;
     } else {  // back-facing camera
         rotation = (info.orientation + orientation) % 360;
     }
     mParameters.setRotation(rotation);
 }
 

Parameters
rotation The rotation angle in degrees relative to the orientation of the camera. Rotation can only be 0, 90, 180 or 270.
Throws
IllegalArgumentException if rotation value is invalid.

public void setSceneMode (String value)

Added in API level 5

Sets the scene mode. Changing scene mode may override other parameters (such as flash mode, focus mode, white balance). For example, suppose originally flash mode is on and supported flash modes are on/off. In night scene mode, both flash mode and supported flash mode may be changed to off. After setting scene mode, applications should call getParameters to know if some parameters are changed.

Parameters
value scene mode.

See also:

public void setVideoStabilization (boolean toggle)

Added in API level 15

Enables and disables video stabilization. Use isVideoStabilizationSupported() to determine if calling this method is valid.

Video stabilization reduces the shaking due to the motion of the camera in both the preview stream and in recorded videos, including data received from the preview callback. It does not reduce motion blur in images captured with takePicture.

Video stabilization can be enabled and disabled while preview or recording is active, but toggling it may cause a jump in the video stream that may be undesirable in a recorded video.

Parameters
toggle Set to true to enable video stabilization, and false to disable video stabilization.

public void setWhiteBalance (String value)

Added in API level 5

Sets the white balance. Changing the setting will release the auto-white balance lock. It is recommended not to change white balance and AWB lock at the same time.

Parameters
value new white balance.

public void setZoom (int value)

Added in API level 8

Sets current zoom value. If the camera is zoomed (value > 0), the actual picture size may be smaller than picture size setting. Applications can check the actual picture size after picture is returned from Camera.PictureCallback. The preview size remains the same in zoom. Applications should check isZoomSupported() before using this method.

Parameters
value zoom value. The valid range is 0 to getMaxZoom().

public void unflatten (String flattened)

Added in API level 1

Takes a flattened string of parameters and adds each one to this Parameters object.

The flatten() method does the reverse.

Parameters
flattened a String of parameters (key-value paired) that are semi-colon delimited
