Mulai CameraX 1.2, Shutter Tanpa Jeda tersedia sebagai mode pengambilan.
Aktifkan Shutter Tanpa Jeda untuk mengurangi latensi secara signifikan dibandingkan dengan
mode pengambilan default, sehingga Anda tidak akan melewatkan gambar.
Shutter Tanpa Jeda menggunakan buffering ring yang menyimpan tiga bingkai pengambilan
terbaru. Saat pengguna menekan tombol rekam, CameraX akan memanggil
takePicture(), dan buffering ring akan mengambil bingkai yang diambil dengan
stempel waktu yang paling dekat dengan penekanan tombol tersebut. CameraX kemudian
memproses ulang sesi pengambilan untuk menghasilkan gambar dari bingkai tersebut, yang
disimpan ke disk dalam format JPEG.
Prasyarat
Sebelum mengaktifkan Shutter Tanpa Jeda, gunakan isZslSupported() untuk menentukan apakah
perangkat Anda memenuhi persyaratan berikut:
Menargetkan Android 6.0+ (level API 23 dan yang lebih baru).
Terakhir, karena menggunakan flash menghasilkan latensi yang lebih besar, Shutter Tanpa Jeda
tidak berfungsi saat flash AKTIF atau dalam mode OTOMATIS. Untuk mengetahui informasi selengkapnya tentang cara menyetel
mode flash, lihat setFlashMode().

To leave feedback on Zero-Shutter Lag, join the [Android CameraX Discussion Group](https://groups.google.com/a/android.com/g/camerax-developers).\n\nStarting in [CameraX 1.2](/jetpack/androidx/releases/camera), Zero-Shutter Lag is available as a capture mode.\nEnable Zero-Shutter Lag to significantly reduce latency compared to the\n[default capture mode](/reference/androidx/camera/core/ImageCapture#CAPTURE_MODE_MINIMIZE_LATENCY()), so you never miss the shot.\n\nEnable Zero-Shutter Lag\n-----------------------\n\nTo enable Zero-Shutter Lag, pass [`CAPTURE_MODE_ZERO_SHOT_LAG`](/reference/androidx/camera/core/ImageCapture#CAPTURE_MODE_ZERO_SHUTTER_LAG()) to\n[`ImageCapture.Builder.setCaptureMode()`](/reference/androidx/camera/core/ImageCapture.Builder#setCaptureMode(int)). If unsuccessful,\n`setCaptureMode()` falls back to `CAPTURE_MODE_MINIMIZE_LATENCY`.\n\nFor more on capture modes, see the [Image capture guide](/media/camera/camerax/take-photo#set-capture-mode).\n\nHow it works\n------------\n\nZero-Shutter Lag uses a ring buffer that stores the three most recent capture\nframes. When a user presses the capture button, CameraX invokes\n[`takePicture()`](/reference/android/hardware/Camera#takePicture(android.hardware.Camera.ShutterCallback,%20android.hardware.Camera.PictureCallback,%20android.hardware.Camera.PictureCallback,%20android.hardware.Camera.PictureCallback)), and the ring buffer retrieves the captured frame with the\ntimestamp that is closest to that of the button press. CameraX then\n[reprocesses](/reference/android/hardware/camera2/CameraDevice#reprocessing) the capture session to generate an image from that frame, which\nsaves to disk in JPEG format.\n\nPrerequisites\n-------------\n\nBefore you enable Zero-Shutter Lag, use [`isZslSupported()`](/reference/androidx/camera/core/CameraInfo#isZslSupported()) to determine if\nyour device meets the following requirements:\n\n- Targets Android 6.0+ (API level 23 and higher).\n- Supports [`PRIVATE` reprocessing](/reference/android/hardware/camera2/CameraMetadata#REQUEST_AVAILABLE_CAPABILITIES_PRIVATE_REPROCESSING).\n\nFor devices that don't meet the minimum requirements, CameraX falls back to\n`CAPTURE_MODE_MINIMIZE_LATENCY`.\n\nZero-Shutter Lag is only available for [Image capture](/training/camerax/take-photo). You cannot enable it\nfor [Video capture](/training/camerax/video-capture) or with [Camera extensions](/training/camera/camera-extensions).\n\nFinally, because using flash results in greater latency, Zero-Shutter Lag does\nnot work when flash is ON or in AUTO mode. For more information about setting\nthe flash mode, see [`setFlashMode()`](/media/camera/camerax/take-photo#set-flash-mode)."]]
