Variable aperture (VA) camera control for controlling a depth of focus

An apparatus, comprising:

• a memory storing processor-readable code;
• and
• at least one processor coupled to the memory, the at least one processor configured to execute the processor-readable code to cause the at least one processor to perform operations including:
• determining a plurality of depths for a scene and a plurality of regions of interest, wherein a first one of the plurality of regions of interest corresponds to a first one of the plurality of depths, which is at a first distance from a reference point, and a second one of the plurality of regions of interest corresponds to a second one of the plurality of depths, which is at a second distance from the reference point;
• determining an aperture size for a camera based on a difference between the first distance and the second distance;
• determining a lens position for the camera that provides a focal plane that is between the first distance and the second distance based on the aperture size and the first one of the plurality of depths and the second one of the plurality of depths;
• and
• controlling the camera to adjust a variable aperture (VA) of the camera based on the determined aperture size and to adjust a lens associated with the variable aperture (VA) based on the determined lens position.
