Patent ID: 7986295

Claim:
An image display control device that corrects an image signal based on statistical information, the image display control device comprising: a statistical information acquisition section that acquires the statistical information of the image signal in a frame unit; a calculator that generates a correction coefficient used to correct the image signal using the statistical information of a preceding frame output from the statistical information acquisition section; and an image correction section that corrects the image signal using the correction coefficient, the statistical information acquisition section including: a plurality of statistical units, each of the plurality of statistical units including a comparator that compares a luminance of the image signal with a reference luminance and outputs a comparison result; a statistical value buffer that updates a count value based on the comparison result; and a statistical value calculation section that calculates a specific statistical value based on the count value of the statistical value buffer that is output from each of the plurality of statistical units, the reference luminance of each of the plurality of statistical units being set to be a different value, and the image signal being parallelly input to each of the plurality of statistical units, the statistical information acquisition section further acquiring statistical information relating to a blue chroma and statistical information relating to a red chroma included in the image signal, and the statistical information acquisition section having a configuration that acquires the statistical information relating to the blue chroma and the statistical information relating to the red chroma, the statistical information acquisition section including: a luminance total value init that includes an adder that accumulates a luminance of each pixel, and a luminance total value buffer that stores the accumulated value as a luminance total value; a blue chroma total value unit that includes an adder that accumulates a blue chroma of each pixel, and a blue chroma total value buffer that stores the accumulated value as a blue chroma total value; a red chroma total value unit that includes an adder that accumulated a red chroma of each pixel, and a red chroma total value buffer that stores the accumulated value as a red chroma total value; and an average calculation section that calculates a luminance average value, a blue chroma average value, and a red chroma average value based on the luminance total value, the blue chroma total value, and the red chroma total value that have been calculated.
