Abstract
A distance measurement accuracy is improved without increasing power consumption of an image processing apparatus that performs distance-measuring processing. In one embodiment, an image processing apparatus for calculating distance information on an image has a reliability calculation unitconfigured to calculate reliability in accordance with contrast for each pixel of the image and a distance calculation unitconfigured to calculate distance information on each of the pixels based on reliability of each of the pixels. The distance calculation unitcalculates the distance information about a second pixel group whose reliability is lower than that of a first pixel group by using a collation area whose size is larger than a predetermined size in a range in which an amount of calculation in a case where a collation area of the predetermined size is used for all the pixels of the image is not exceeded.
