Abstract:
An image processor includes 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 outputs a second correction value, which corresponds to the pixel value of the input image, based on a second correction characteristic. A control circuit controls a ratio for mixing the first correction value and the second correction value. A mixing circuit that mixes the first correction value and the second correction value based on the ratio. 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.
