PROBLEM TO BE SOLVED: To provide an image processing apparatus configured to improve image quality of input image data, an image processing method, an image processing program, and an information recording medium with the program recorded thereon.SOLUTION: An image processing apparatus 1 which generates output image data D81 by correcting input image data D1 with attribute information A1 and illumination information W1 includes: N edge-preservation weighted average calculation parts 21, 22, 23; N subtractors 31, 32, 33; a gain calculation parameter selection information calculation part 11; N+1 base component cooperation gain calculation parts 41, 42, 43, 44; N band cooperation gain calculation parts 51, 52, 53; N composite multipliers 61, 62, 63; a base component multiplier 74; N band division multipliers 71, 72, 73; and an adder 81. A contrast adjustment degree for each frequency band is changed with respect to an area having different attribute information and illumination information in the image, thereby improving image quality of a captured image. |
