Abstract:
1. A display device, comprising: a pixel array unit having display elements formed in vicinity of intersections of signal lines and scanning lines arranged in length and breadth, image pickup unit and an output unit which outputs binary data corresponding to image picked up by said image pickup unit; a image pickup device provided separate from said image pickup unit; a first image processing unit configured to generate multiple gradation data based on multiple binary data picked up by said image pickup units based on multiple image pickup conditions; a second image processing unit configured to receive either the image pickup data picked up by said image pickup device or the multiple gradation data generated by said first image processing unit, to conduct a prescribed image processing; a display controller IC which embeds said first image processing unit and supplies digital pixel data for said pixel array unit to said pixel array; a temporary storage capable of storing image pickup data of said image pickup unit for three horizontal lines; and a virtual image pickup display detector, wherein said pixel array unit is formed on an insulation substrate using TFTs (Thin Film Transistors), while said first image processing unit is transmitting the image pickup data stored in said temporary storage to said second image processing unit, the virtual image pickup data detector calculates the central image pickup data, and transfers the calculation result to said temporary storage, said first image processing unit is a semiconductor chip.
