Abstract

An image processing apparatus includes: a histogram computation block configured to compute a histogram of a plurality of motion vectors of each image detected for each of continuously taken images; an acceleration vector computation block configured to compute an acceleration vector corresponding to a change in the histogram; and a camera-shake correction amount computation block configured, on the basis of the acceleration vector and first motion vector for correction used in processing on an image preceding an image subject to processing, by assuming a second motion vector for correction for use in processing on the image subject to processing, to compute a camera-shake correction amount corresponding to the second motion vector for correction.

First claim

What is claimed is:

1. An image processing apparatus comprising:
one or more processors operable to:
compute a histogram of a plurality of motion vectors of each image of a plurality of images;
compute an acceleration vector corresponding to a change in said histogram; and
compute a camera-shake correction amount, comprising:
computing, based on said acceleration vector and a first motion vector used in processing a first image, a second motion vector for use in processin…
