IMAGE PROCESSOR, IMAGE PROCESSING METHOD, PROGRAM AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To achieve image processing technique for normally detecting motion without the need of complicated processing by synthesizing a plurality of images photographed by changing exposure conditions after exposure error correction corresponding to a position of a screen is performed.SOLUTION: The image processor for synthesizing a plurality of images photographed by changing exposure conditions includes: detecting means for detecting an exposure error corresponding to a position of a screen with an image whose exposure amount is smaller than a prescribed value as an image of a detection object in the plurality of images photographed by changing the exposure conditions; calculating means for calculating correction information for correcting the exposure error detected by the detecting means in accordance with the position of the screen; adjusting means for adjusting a level corresponding to the exposure amount of the image being the detection object in accordance with the correction information and the position information of the screen; and image synthesizing means for synthesizing the plurality of images including the image whose level is adjusted and generating a synthesized image.
