First Claim
Patent Images
1. An image pickup apparatus, comprising:
- image pickup means having an image pickup surface formed thereon from pixels arranged in a matrix for outputting a result of image pickup of an optical image formed on the image pickup surface;
motion detection means for detecting a motion amount in the result of the image pickup for each of blocks into which the image pickup surface is divided in a horizontal direction and/or a vertical direction;
control means for controlling exposure time of said image pickup means for each of the blocks based on a result of the detection by said motion detection means; and
signal level correction means for correcting and outputting, for each of the blocks, a signal level of the result of the image pickup which varies in accordance with control of the exposure time.

7. A processing method for a result of image pickup, comprising:
-
a motion detection step of detecting a motion amount in a result of image pickup by image pickup means for each of blocks into which an image pickup surface of the image pickup means is divided in a horizontal direction and/or a vertical direction; a control step of controlling exposure time of the image pickup means for each of the blocks based on a result of the detection at the motion detection step; and a signal level correction step of correcting and outputting, for each of the blocks, a signal level of the result of the image pickup which varies in accordance with control of the exposure time.
