Claim:
1. An image processing device, comprising: a dark channel image generating section for generating, by an arithmetic unit, a dark channel image based on an input image; a transmittance image generating section for generating, by the arithmetic unit, a transmittance image based on the dark channel image generated by the dark channel image generating section and a pixel value of atmospheric light; a transmittance correcting section for correcting, by the arithmetic unit, the transmittance image generated by the transmittance image generating section; and a fog removal image generating section for removing, by the arithmetic unit, fog in the input image based on the transmittance image corrected by the transmittance correcting section, the pixel value of atmospheric light, and the input image; wherein the transmittance correcting section divides the transmittance image into predetermined areas, performs binarization according to an average value of transmittances of each pixel in each divided predetermined area, and selects transmittances of each pixel in each predetermined area based on a number of each value binarized in each predetermined area and an average value of transmittances of each value in each predetermined area.
