Abstract
An image processing apparatus capable of supplementing luminance by an amount of deterioration even if the degree of deterioration of a light emitting element of a pixel advances along with aging, comprising an image information extraction unit for quantizing an input image by threshold values Vth designated from a CPU and adding the quantized image to an image quantized in a previous frame in units of dots; a memory for storing the image data quantized and added for each frame; a CPU for reading out the image data stored in the memory, monitoring the deterioration degree for each pixel, and outputting a γ-conversion table for the suitable γ-correction for each pixel to an image processing unit when burn-in becomes remarkable; and an image processing unit for performing γ-correction for reducing the deterioration for each pixel for each color based on the γ-conversion table.
