Abstract: There are provided: 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.

Abstract: Techniques are provided in which a “dichromat” (e.g., a color-blind person) is able to identify the hue of an object without determining the color difference signals that are applied to the original color image. Such features may be implemented by performing hue rotation processing on each pixel data of the original color image captured.

Abstract: An image processing apparatus (100) is formed including: color image acquisition means (222) for acquiring a color image of an object, which is expressed by a luminance signal, a first color difference signal that is a color difference signal of a color pair that is easy to be identified by a dichromat and a second difference signal that is a color difference signal of a color pair that is difficult to be identified by the dichromat; color difference signal processing means (223) for performing mixing reprocessing that mixes a component of the second color difference signal with a component of the first color difference signal, for each pixel data of the color image; and display control means (230) for performing control to display the color image processed by the color difference signal processing means (223) on a display unit (109) as a color image subjected to color conversion. By this means, it is possible to provide a mechanism in which a dichromat can understand the hue of an object without learning.
