Claim 30:
31. An apparatus, comprising:
a camera comprising an image sensor and a lens;
a memory storing processor-readable code; and
at least one processor coupled to the memory and to the camera, the at least one processor configured to execute the processor-readable code to cause the at least one processor to perform operations including:
controlling the camera to obtain a first image frame representing a scene captured at a first focal distance;
determining the first image frame includes a first face associated with the first focal distance and a second face associated with a second focal distance;
controlling the camera to obtain a second image frame representing the scene captured at a third focal distance between the first focal distance and the second focal distance;
controlling the camera to obtain a third image frame representing the scene captured at the second focal distance;
determining a corresponding set of regions of interest comprising a first region of interest in the second image frame associated with the first face and a second region of interest in the third image frame associated with the first face;
determining a value based on a comparison of the first region of interest with the second region of interest; and
determining a corrected image frame based on the second image frame and the value.
