Abstract:
1. An image processing apparatus comprising: an image combination unit which generates combined images by combining photographed images having different exposure times; a motion area detection unit which performs a comparison process on a plurality of the combined images generated by the image combination unit to acquire a pixel value difference and which performs a motion area detection process of comparing the pixel value difference with a predetermined threshold value and determining a pixel area, of which the pixel value difference is equal to or larger than the threshold value, to be a motion area where motion of a subject is estimated to have occurred; a before-combination image comparison unit which acquires the pixel value difference between to-be-combined images by comparing output values of the corresponding pixels between the to-be-combined images which are sources for generation of the combined images; and an over-detection removing unit which compares the pixel value difference between the to-be-combined images with a predetermined second threshold value and determines a pixel area, of which the pixel value difference between to-be-combined images is less than the second threshold value, not to be the motion area with respect to the corresponding pixels of the motion area detected by the motion area detection unit.
