<P>PROBLEM TO BE SOLVED: To carry out high-accuracy image persistence correction. <P>SOLUTION: A light receiving sensor 3 mounted on an EL panel 2 measures the emission luminance of a target pixel and outputs the luminance as an analog light reception signal. A variable amplifying unit 51 amplifies the light reception signal of the target pixel output from the light-receiving sensor 3 by a prescribed amplification rate. An A/D converting unit 52 converts the amplified light reception signal into a digital signal to output. A signal processing unit 53 computes a correction data for reduction in the luminance due to degradation with time on the basis of the digital data, corrects a video signal corresponding to the target pixel on the basis of the correction data, and supplies the corrected video signal to the target pixel of the EL panel 2. A dark current correcting unit 71 corrects the light reception signal by eliminating a dark current component of the light-receiving sensor included in the light reception signal of the target pixel output from the light-receiving sensor 3. The present invention is applied, for example, to a panel using a self-luminous element. <P>COPYRIGHT: (C)2010,JPO&INPIT |
