Parameters


open class Parameters
kotlin.Any
   ↳ android.hardware.Camera.Parameters

Camera service settings.

To make camera parameters take effect, applications have to call Camera#setParameters(Camera.Parameters). For example, after Camera.Parameters#setWhiteBalance is called, white balance is not actually changed until Camera#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 Camera.Parameters#getSupportedColorEffects() before calling Camera.Parameters#setColorEffect(String). If the camera does not support color effects, Camera.Parameters#getSupportedColorEffects() will return null.

Value: "auto"

FOCUS_MODE_CONTINUOUS_PICTURE

Added in API level 14
Deprecated in API level 21
static val FOCUS_MODE_CONTINUOUS_PICTURE: String

Deprecated: Deprecated in Java.

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(android.hardware.Camera.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.

Auto focus starts when the parameter is set.

Since API level 14, applications can call autoFocus(android.hardware.Camera.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.

getExposureCompensation

Added in API level 8
Deprecated in API level 21
open fun getExposureCompensation(): Int

Deprecated: Deprecated in Java.

Gets the current exposure compensation index.

Return
Int current exposure compensation index. The range is getMinExposureCompensation to getMaxExposureCompensation. 0 means exposure is not adjusted.

getExposureCompensationStep

Added in API level 8

open fun getExposureCompensationStep(): Float

Deprecated: Deprecated in Java.

Gets the exposure compensation step.

Return

getFocalLength

Added in API level 8
Deprecated in API level 21
open fun getFocalLength(): Float

Deprecated: Deprecated in Java.

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

Return
Float the focal length. Returns -1.0 when the device doesn't report focal length information.

getFocusAreas

Added in API level 14
Deprecated in API level 21
open fun getFocusAreas(): MutableList<Camera.Area!>!

Deprecated: Deprecated in Java.

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

Before using this API or setFocusAreas(java.util.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.

Return
MutableList<Camera.Area!>! a list of current focus areas

getFocusDistances

Added in API level 9
Deprecated in API level 21
open fun getFocusDistances(output: FloatArray!): Unit

Deprecated: Deprecated in Java.

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(android.hardware.Camera.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 FloatArray!: 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.

getFocusMode

Added in API level 5
Deprecated in API level 21
open fun getFocusMode(): String!

Deprecated: Deprecated in Java.

Gets the current focus mode setting.

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

getHorizontalViewAngle

Added in API level 8
Deprecated in API level 21
open fun getHorizontalViewAngle(): Float

Deprecated: Deprecated in Java.

Return
Int the maximum number of metering areas supported by the camera.

getMaxZoom

Added in API level 8
Deprecated in API level 21
open fun getMaxZoom(): Int

Deprecated: Deprecated in Java.

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.

Return
Int the maximum zoom value supported by the camera.

getMeteringAreas

Added in API level 14
Deprecated in API level 21
open fun getMeteringAreas(): MutableList<Camera.Area!>!

Deprecated: Deprecated in Java.

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

Before using this API or setMeteringAreas(java.util.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).

Return
MutableList<Camera.Area!>! a list of current metering areas

getMinExposureCompensation

Added in API level 8
Deprecated in API level 21

If the returned list is not null, the returned list will contain at least one Size and one of the sizes in the returned list must be passed to MediaRecorder.setVideoSize() for camcorder application if camera is used as the video source. In this case, the size of the preview can be different from the resolution of the recorded video during video recording.

Exception on 176x144 (QCIF) resolution: Camera devices usually have a fixed capability for downscaling from larger resolution to smaller, and the QCIF resolution sometimes is not fully supported due to this limitation on devices with high-resolution image sensors. Therefore, trying to configure a QCIF video resolution with any preview or picture size larger than 1920x1080 (either width or height) might not be supported, and setParameters(android.hardware.Camera.Parameters) will throw a RuntimeException if it is not.

Return
Boolean true if smooth zoom is supported.

isVideoSnapshotSupported

Added in API level 14
Deprecated in API level 21
open fun isVideoSnapshotSupported(): Boolean

Deprecated: Deprecated in Java.

Returns true if video snapshot is supported. That is, applications can call takePicture(android.hardware.Camera.ShutterCallback,android.hardware.Camera.PictureCallback,android.hardware.Camera.PictureCallback,android.hardware.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.

Return
Boolean true if video snapshot is supported.

setAutoExposureLock

Added in API level 14
Deprecated in API level 21
open fun setAutoExposureLock(toggle: Boolean): Unit

Deprecated: Deprecated in Java.

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(android.hardware.Camera.ShutterCallback,android.hardware.Camera.PictureCallback,android.hardware.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 Boolean: 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.

setAutoWhiteBalanceLock

Added in API level 14
Deprecated in API level 21
open fun setAutoWhiteBalanceLock(toggle: Boolean): Unit

Deprecated: Deprecated in Java.

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(android.hardware.Camera.ShutterCallback,android.hardware.Camera.PictureCallback,android.hardware.Camera.PictureCallback), will not change the the lock.

Changing the white balance mode with setWhiteBalance 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 Boolean: 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.

Exception on 176x144 (QCIF) resolution: Camera devices usually have a fixed capability for downscaling from larger resolution to smaller, and the QCIF resolution sometimes is not fully supported due to this limitation on devices with high-resolution image sensors. Therefore, trying to configure a QCIF picture size with any preview or video size larger than 1920x1080 (either width or height) might not be supported, and setParameters(android.hardware.Camera.Parameters) might throw a RuntimeException if it is not.

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

setPreviewFormat

Added in API level 1
open fun setPreviewFormat(pixel_format: Int): Unit

Deprecated: Deprecated in Java.

Sets the image format for preview pictures.

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

Use Parameters#getSupportedPreviewFormats to get a list of the available preview formats.

It is strongly recommended that either android.graphics.ImageFormat#NV21 or android.graphics.ImageFormat#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 android.graphics.ImageFormat#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:

<code>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;
  </code>
Parameters
pixel_format Int: the desired preview picture format, defined by one of the android.graphics.ImageFormat constants. (E.g., ImageFormat.NV21 (default), or ImageFormat.YV12)

Deprecated: Deprecated in Java.

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. Exception on 176x144 (QCIF) resolution: Camera devices usually have a fixed capability for downscaling from larger resolution to smaller, and the QCIF resolution sometimes is not fully supported due to this limitation on devices with high-resolution image sensors. Therefore, trying to configure a QCIF preview size with any picture or video size larger than 1920x1080 (either width or height) might not be supported, and setParameters(android.hardware.Camera.Parameters) might throw a RuntimeException if it is not.

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

setRecordingHint

Added in API level 14
Deprecated in API level 21
open fun setRecordingHint(hint: Boolean): Unit

Deprecated: Deprecated in Java.

Sets recording mode hint. This tells the camera that the intent of the application is to record videos android.media.MediaRecorder#start(), not to take still pictures takePicture(android.hardware.Camera.ShutterCallback,android.hardware.Camera.PictureCallback,android.hardware.Camera.PictureCallback,android.hardware.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 Boolean: true if the apps intend to record videos using android.media.MediaRecorder.

setRotation

Added in API level 5
Deprecated in API level 21
open fun setRotation(rotation: Int): Unit

Deprecated: Deprecated in Java.

Sets the clockwise rotation angle in degrees relative to the orientation of the camera. This affects the pictures returned from JPEG 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 android.view.OrientationEventListener and android.hardware.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 Int: The rotation angle in degrees relative to the orientation of the camera. Rotation can only be 0, 90, 180 or 270.
Exceptions
java.lang.IllegalArgumentException if rotation value is invalid.

setSceneMode

Added in API level 5
Deprecated in API level 21
open fun setSceneMode(value: String!): Unit

Deprecated: Deprecated in Java.

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 String!: scene mode.

setVideoStabilization

Added in API level 15
Deprecated in API level 21
open fun setVideoStabilization(toggle: Boolean): Unit

Deprecated: Deprecated in Java.

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 android.hardware.Camera#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 Boolean: Set to true to enable video stabilization, and false to disable video stabilization.

setWhiteBalance

Added in API level 5
Deprecated in API level 21
open fun setWhiteBalance(value: String!): Unit

Deprecated: Deprecated in Java.

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 String!: new white balance.

setZoom

Added in API level 8
Deprecated in API level 21
open fun setZoom(value: Int): Unit

Deprecated: Deprecated in Java.

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 PictureCallback. The preview size remains the same in zoom. Applications should check isZoomSupported before using this method.

Parameters
value Int: zoom value. The valid range is 0 to getMaxZoom.

unflatten

Added in API level 1
open fun unflatten(flattened: String!): Unit

Deprecated: Deprecated in Java.

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

The flatten() method does the reverse.

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