An image processing apparatus (1) for compressing a range of bit number of each pixel value configuring an input image from an A bit to a B bit (A > B), comprises: a maximum value detection unit (41) for detecting a maximum value of pixel values configuring an input image; an extra determination unit (42) for determining an extra value according to the maximum value; a coefficient calculation unit (44) for calculating a coefficient according to an adding result of the maximum value and the extra value; and a compression unit (45) for compressing a range of the input image by using the coefficient. |
