1. An image processing device comprising:

  • an area dividing circuita focus area judgment circuit connected to the area dividing circuitan area dedicated color conversion RGB value calculation circuit connected to both the area dividing circuit and the focus area judgment circuit anda display device,whereinthe area dividing circuit is configuredto input data showing an image, to divide the image into a plurality of blocks,to convert the input data showing the image to image data including color information of image data indicating red, image data indicating green and image data indicating blue,to allocate the image data including the color information into each of the blocks,to output data of the blocks as area dividing data, andto output the image data including the color information allocated to each of the blocks as area dedicated RGB data;

    the focus area judgment circuit is configuredto input the area dividing data from the area dividing circuit,to divide data of the blocks into a first image area and a second image area, andto output the divided area data including the first image area and the second image area as focus area judgment data,the area dedicated color conversion RGB value calculation circuit configuredto input the area dedicated RGB data from the area dividing circuit,to input the focus area judgment data from the focus area judgment circuit,to compare the area dedicated RGB data and the focus area judgment data,in the case where the area dedicated RGB data is included in the first image area, to calculate first color conversion data obtained by converting the area dedicated RGB data included in the first image area into image data emphasizing a color of a long wavelength from the area dedicated RGB data and an intensity coefficient to emphasize color, andin the case where the area dedicated RGB data is included in the second image area, to calculate second color conversion data obtained by converting the area dedicated RGB data included in the second image area into image data emphasizing a color of a short wavelength from the area dedicated RGB data, the intensity coefficient and a luminosity coefficient, andto output data showing an RGB image including the first color conversion data and the second color conversion data; and

    the display device is configuredto input the output data showing an RGB image from the area dedicated color conversion RGB value calculation circuit, andto display an image in which tone of the first image area is enhanced more than tone of the second image area.
