IMAGE PROCESSING APPARATUS, IMAGE CAPTURING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM

There is provided an image processing apparatus. An obtaining unit obtains a distance map and a shot image, the distance map representing a distribution of information related to a distance in a depth direction of a shooting range using a distribution of distance values, the shot image corresponding to the shooting range. A first filter unit applies a first filter to the distance map. A second filter unit applies a second filter to the distance map to which the first filter has been applied. The first filter is a filter that reduces a distribution of distance values in a predetermined distance value range in the distance map. The second filter is a filter that changes a distance value of a target distance in the distance map using weighted averaging.
