An image processing apparatus includes an image generating unit configured to generate a polarization sensitive tomographic image indicating polarization characteristics of an object based on tomographic signals acquired from the object using light interference, an extracting unit configured to extract a depolarization region of the object, based on the tomographic signals, and a display control unit configured to display, on a display unit, a region on the polarization sensitive tomographic image corresponding to the depolarization region, in a state distinguishable from other regions.
