As a result, theīuffer is rotated 90 degrees clockwise.
Orientation matches the device orientation:Ī back-facing camera would produce an image buffer with the same orientationĪs the buffer above, but SENSOR_ORIENTATION is 90 degrees. The image must be rotated 270 degrees counterclockwise so that the preview’s Produced by the camera sensor looks like this: The rotation is counterclockwise for back-facing cameras, clockwise.įor example, for the front-facing camera in figure 1, the image buffer Number of degrees specified by SENSOR_ORIENTATION for the camera preview toĪppear upright in the device’s natural orientation.

Of the front-facing camera (the camera pointing in the same direction as theĭisplay) is rotated 270 degrees relative to the phone to comply with the The camera sensor’s natural orientation is landscape. Typical relationship of phone and camera sensor Also, image sensors typically output their data in landscape aspect This arrangement maximizes the display area for the camera viewfinder in aĬamera app. Specifies that a camera image sensor “MUST be oriented so that the longĭimension of the camera aligns with the screen’s long dimension.” The same orientation as the primary display. Multi-display mode enables the use of secondary displays which might not be in
