The invention provides an image processing device and an image processing method, which not only can inhibit processing load in the colorful image processing, but also can let the polychromate to grasp color vision of people with unnormal polychromate (I type/2 type dichromat). The device comprises: an original color image capturing unit capturing an original color image of a object represented by YCbCr; a Cr component elimination processing unit performing, on each pixel data of the original color image captured by the original color image capturing unit, processing to make a value of Cr component to be zero; a hue rotation processing unit performing, on each pixel data of the color image after being subjected to the processing performed by the Cr component elimination processing unit, hue rotation processing of 5 degrees to 50 degrees in a CbCr color space; and a display control unit performing a control to display the color image after being subjected to the hue rotation processing performed by the hue rotation processing unit, on a display section as a hue-converted color image.
