Patent ID: 8675962

Claim:
An image correction process circuit, comprising: an image correction portion that applies a predetermined image correction process to an input image to generate an output image; a calculation portion that obtains a luminance histogram for every one field of the input image and calculates two values or all three values of an average luminance value, a standard deviation value and an intermediate value; and a correction control portion that based on two values or all the three values of the average luminance value, the standard deviation value and the intermediate value of the luminance histogram which are calculated by the calculation portion, determines whether or not the image correction process is necessary for the input image and a correction amount for the image correction process, and performs control of the image correction portion, wherein the image correction portion applies a foggy-image correction process to the input image; and the correction control portion, based on the average luminance value and the standard deviation value of the luminance histogram, determines whether the foggy-image correction process is necessary or not for the input image and the correction amount for the image correction process.
