PROBLEM TO BE SOLVED: To pick up the image of delicate idle slide information, which has complicated ruggedness, or the like with fidelity. SOLUTION: In a unidirectional idle illumination slide information extracting part 13, concerning a slanted illumination input image picked up while using a multidirectional illumination, a ratio with each of pixels in an upright illumination input image is found. In a rugged image luminance correcting part 14, concerning each of provided rugged images, flattening processing is performed for removing the incline of luminance between respective pixels and in a luminance reference matching part 15, luminance reference matching processing is performed for matching luminance references by correcting the inequality of luminance references for each of images. In a multidirectional idle slide information synthesizing part 16, image processing is performed for further extracting idle slide information from each of rugged images and adding the information to the upright illumination input image so that one image containing the idle slide information can be provided. |
