Abstract
An image processing apparatus includes: a composite unit that generates a composite parameter used for implementing a time varying variation correction processing for suppressing color variations associated with lapse of time and a spatial variation correction processing for suppressing color variations in accordance with a position in an image, on the basis of a time varying correction parameter used for the time varying variation correction processing and a spatial correction parameter used for the spatial variation correction processing; and an image correction unit that subjects input image data to the time varying variation correction processing and the spatial variation correction processing through use of the composite parameter generated by the composite unit.
