摘要
An irregular color and irregular luminance correction circuit includes a memory, a CPU (Central Processing Unit), and an external interface. In the memory, luminance distribution values, luminance inclination values, screen distribution values, and correction values at n-pieces of levels at each correction point obtained at factory adjustment are stored as digital data. The CPU generates a correction value based on the luminance distribution value, the luminance inclination value, and the screen distribution value and stores these values in the memory as digital data. The irregular color and irregular luminance correction circuit performs irregular color and irregular luminance correction for an input image signal based on the correction value and an interpolation value. With these configurations, irregular color and irregular luminance caused by a display device and a screen in a projector can be solved.
