Abstract:
1. An image processor comprising: a first correction circuit that outputs a first correction value, which corresponds to a pixel value of an input image, based on a first correction characteristic; a second correction circuit that outputs a second correction value, which corresponds to the pixel value of the input image, based on a second correction characteristic; a control circuit that controls a ratio for mixing the first correction value and the second correction value, wherein the control circuit is configured to change the ratio in a plurality of stages and includes a table that stores the ratio at each of the stages and a number of frames of the input image in association with the ratio; and a mixing circuit that mixes the first correction value and the second correction value based on the ratio, wherein the mixing circuit is configured to mix the first correction value and the second correction value at the same ratio for the input image corresponding to the number of frames, and wherein a corrected pixel value, which corresponds to the pixel value of the input image, is generated in accordance with an output value of the mixing circuit.
