Blur detection apparatus and blur detection method

摘要

Positional shifts of subject images in plural areas of a light receiving surface are respectively detected in a blur detection apparatus for a camera for detecting blur based on chronological positional shifts of subject images on a light receiving surface. This allows blur of the main subject to be distinguished from that in the background in the image. The subject image position may be detected using an AF sensor. An acceleration sensor may be used for detecting blur in images with insufficient brightness or contrast. Blur detection by the acceleration sensor should account for a time interval between accelerations-one detected in one direction and the other in the opposite direction.
