Abstract
A method provides phase disparity data. First phase disparity data for a first image frame of a first scene is computed using a phase disparity engine of an image capture device. The method determines whether the image capture device is receiving light from a second scene that is different from the first scene and corresponds to a second image frame. The phase disparity engine discontinues computing of phase disparity data, in response to a determination that the second scene is not different from the first scene. The first phase disparity data are output in connection with the second image frame, in response to determining that the second scene is not different from the first scene.
Claims26
A method for providing phase disparity data, comprising:
- computing first phase disparity data for a first image frame of a first scene using a phase disparity engine of an image capture device;
- determining that a second scene of a second image frame is equivalent to the first scene;
- discontinuing computing of phase disparity data by the phase disparity engine, in response to the determination that the second scene is equivalent to the first scene;
- and
- outputting the first phase disparity data in connection with the second image frame, in response to the determination that the second scene is equivalent to the first scene.
An image capture device, comprising:
- an imaging sensor having a plurality of phase detection pixels;
- and
- a phase disparity engine coupled to the sensor, the phase disparity engine including at least one processor configured to:
- compute first phase disparity data for a first image frame of a first scene;
- determine that a second scene of a second image frame is equivalent to the first scene;
- discontinue computing of phase disparity data, in response to the determination that the second scene is equivalent to from the first scene;
- and
- output the first phase disparity data in connection with the second image frame, in response to the determination that the second scene is equivalent to the first scene.
An image capture device, comprising:
- means for capturing data including phase disparity information;
- means for computing a phase disparity data for a first scene of a first image frame;
- means for outputting the phase disparity data;
- and
- means for determining that a second scene of a second image frame is equivalent to the first scene;
- wherein the means for computing phase disparity data is configured for discontinuing computing of phase disparity data, in response to the determination that the second scene is equivalent to the first scene;
- and
- wherein the means for outputting the phase disparity data is configured to output a first phase disparity data in connection with the first image frame and to output the first phase disparity data in connection with the second image frame, in response to the determination that the second scene is equivalent to the first scene.
A non-transitory, machine-readable storage medium encoded with program code that is executable by a processor for providing phase disparity data, the program code comprising:
- program code for computing first phase disparity data for a first image frame of a first scene using a phase disparity engine of an image capture device;
- program code for determining that a second scene of a second image frame is equivalent to the first scene;
- program code for discontinuing computing of phase disparity, in response to the determination that the second scene is equivalent to the first scene;
- and
- program code for outputting the first phase disparity data in connection with the second image frame, in response to the determination that the second scene is equivalent to the first scene.
