1. An apparatus, comprising:
processing circuitry configured to
receive a first image from an image sensor,
determine auto focus information with respect to an object in the first image based on a distance to the object based on a depth map,
set a first area based on calculating a first outer point and a second outer point associated with the object using the depth map,
set a second area based on a particular ratio, the particular ratio determined based on the first outer point and the second outer point, and
determine auto zoom information based on calculating a zoom ratio corresponding to a size of the second area.
