摘要： Even when the brightness of an image in a video changes, detection of an object in the background is realized by accurately separating the object in the background from the background of the image. An image processing device in accordance with the present invention executes a process of converting a color space of a processing target image and acquiring color information on the converted color space, a process of calculating, for the target image, an average value of the brightness of color information on a target region that contains an object to be detected, and a process of comparing, for the target region, the brightness of color information on each pixel with the calculated average value, a process of generating a corrected image with corrected brightness/darkness, and a process of extracting the object on the basis of the corrected image (See Fig. 1).
