Abstract:
1. An image processing apparatus comprising: image area setting means for causing each pixel included in a photographed photograph-image to be a correction target pixel in order, and sets an image area including the correction target pixel and plural pixels existing near the correction target pixel; prescribed value calculation means for calculating a prescribed value based on brightness information of pixels included in the image area for every image area set by the image area setting means; correction value calculation means for dividing a brightness target value of a whole photograph-image by the prescribed value calculated by the prescribed value calculation means to calculate a correction value; and, correction processing means for multiplying the brightness information of the correction target pixel of the image area by the correction value calculated by the correction value calculation means to execute a brightness correction processing, wherein if the correction target pixel is a pixel which has pixels only in a part of a surrounding area, the image area setting means sets sides of the photographed photograph-image to a symmetric axis, and complements pixels in an other part of the surrounding area with pixels-formed in the area by folding back the photographed photograph-image in order of the symmetric axis.
