摘要 <p><P>PROBLEM TO BE SOLVED: To favorably adjust the contrast of an image. <P>SOLUTION: This image processor inputs the image, conducts rank calculation processing for calculating a pixel value histogram of the input image as the first histogram, and for calculating a rank of level of a pixel value in the first histogram of the pixel value of an image processing-objective pixel in the input image, and image conversion processing for changing the pixel value of the pixel value of the image processing-objective pixel, into the pixel value of the calculated rank in the second histogram of a pixel histogram different from the first histogram, and outputs the image conversion-processed image. <P>COPYRIGHT: (C)2010,JPO&INPIT</p>
