APPARATUS, METHOD, AND MEDIUM

摘要

The present invention is a control apparatus for controlling an image capturing sensor, the control apparatus comprising: a generation unit configured to selectively determine an exposure time from at least two or more different exposure times for each pixel constituting image data and to generate exposure time data indicative of an exposure time for each pixel; and a gain adjustment processing unit configured to make a gain adjustment to the image data based on the determined exposure time, wherein the generation unit calculates an output value from acquired image data, determines an exposure time for each pixel based on the calculated output value, calculates an error related to the calculated output value, and diffuses the calculated error to pixels adjacent to a processing-target pixel, thereby turning a pixel switching pattern into a blue noise pattern.
