![]() CameraX then reprocesses the capture session to generate an image from that frame, which is saved to disk in JPEG format. When a user presses the capture button, CameraX invokes takePicture(), and the ring buffer retrieves the captured frame with the timestamp that is closest to that of the button press. ![]() Zero-Shutter Lag uses a ring buffer that stores the three most recent capture frames. With Zero-Shutter Lag enabled, latency is significantly reduced compared to the default capture mode, CAPTURE_MODE_MINIMIZE_LATENCY, so that you will never miss the shot. Starting in 1.2, Zero-Shutter Lag ( CAPTURE_MODE_ZERO_SHOT_LAG) is available as a capture mode. To leave feedback on Zero-Shutter Lag, join the Android CameraX Discussion Group. Zero-Shutter Lag Note: Zero-Shutter Lag is still an experimental feature. The capture mode defaults to CAPTURE_MODE_MINIMIZE_LATENCY.įor more information, see the setCaptureMode() reference documentation. CAPTURE_MODE_MAXIMIZE_QUALITY: optimize image capture for image quality.CAPTURE_MODE_MINIMIZE_LATENCY: optimize image capture for latency.To configure the capture mode when taking a photo: Such as flash, continuous auto-focus, zero-shutter lag, and more. Image capture provides basic controls for taking pictures, If the executor is absent, CameraX will default to an internal IO executor for ![]() If the caller chooses to save the image to a file location, you can specifyĪn executor to do the IO.Used to execute the user-provided OnImageCapturedCallback(). The callback executor is the parameter of the takePicture methods.The callback executor and the IO executor. There are two types of customizable executors on which ImageCapture runs, This method saves the captured image to the provided file location. takePicture(OutputFileOptions, Executor, OnImageSavedCallback):.This method provides an in-memory buffer of the captured image. takePicture(Executor, OnImageCapturedCallback):.The caller is responsible for deciding how to use the captured picture, High-quality photos and provides auto-white-balance, auto-exposure, andĪuto-focus (3A) functionality, in addition to simple manual camera controls. The image capture use case is designed for capturing high-resolution,
