Image capturing apparatus, image processing method and program

摘要

This invention provides an image free from camera shake by using a plurality of images captured by a camera array image capturing apparatus. A determination unit determines whether to execute a camera shake correction processing. A memory unit temporarily stores only a group of images determined by a determination unit to be camera shake corrected. A camera shake correcting unit synthesizes images to correct blurs in the images. A matching point searching unit determines matching pixels by checking pixel value similarity between images. A moving amount calculating unit, based on the result acquired by the matching point searching unit, calculates a moving amount of each pixel between images. A position correcting unit, based on the moving amount of each pixel calculated by the moving amount calculating unit, corrects the positions of the images. An image synthesizing unit synthesizes a group of images that are position-corrected by the position correcting unit.

主权项

1. A camera array comprising:
a plurality of image capturing units including at least a first image capturing unit with a first focal distance and a second image capturing unit with a longer focal distance than the first focal distance; and an output unit configured to output first image data acquired by the first image capturing unit without performing a camera shake correction, and output second image data acquired by the second image capturing unit after performing the camera shake correction; wherein, in response to one image capturing operation, the second image capturing unit captures a plurality of images of a subject to acquire the second image data representing a plurality of images; wherein the output unit synthesizes the plurality of images represented by the second image data to perform the camera shake correction.
