摘要：In order to obtain a good image without degradation of image quality bypermitting accurate detection of a defective pixel and further compensation for thedefective pixel even with occurrence of the defect originating in TFT during operation, it ismade possible to detect the defective pixel by self-diagnosis. The detection is carried outin such a manner that in a dark state the voltage applied to the photoelectric conversionelements is changed from a first voltage in normal reading to a second voltage andoutputs read out of the charged photoelectric conversion elements are compared with apredetermined threshold.
