PROBLEM TO BE SOLVED: To attain calculation for color correction with one subroutine by unifying number of blocks different from a size of a negative. SOLUTION: The color scanning device is provided with an image pickup section 10, an arithmetic processing section 20, an exposure section 40, and a control section 50. The arithmetic processing section 20 consists of an image input means 21, a color data calculation means 22, a hue calculation section 23, a saturation calculation section 24, a color correction calculation means 25, an exposure calculation means 26, an exposure output means 27, a color data memory 31, a hue saturation memory 32, and a color correction memory 33. The arithmetic processing section 20 divides the image by a prescribed block number independently of a negative size and applies arithmetic processing to each block.
