Abstract: An organic photoelectric film on a substrate may perform photoelectric conversion of incident light. Pixel electrodes are arranged in a matrix form in an X-axis direction and a Y-axis direction between the substrate and the organic photoelectric film. A driving circuit may read pixel information from each pixel electrode of a pixel electrode line including a plurality of pixel electrodes arranged in the X-axis direction, and applies an on-voltage or an off-voltage to each pixel electrode 40 of the pixel electrode line. The driving circuit may scan a photoelectric conversion ON region to which the on-voltage is applied in the −Y-axis direction in synchronization with a timing of scanning a read line to which the pixel information is read in the −Y-axis direction.

Abstract: A moving image processing apparatus is configured to extract position information of a saturation region from a first frame, the saturation region including pixels each having at least a threshold pixel value that is associated with an afterimage being formed in a subsequent frame elapsed from the first frame. The moving image processing apparatus is configured to extract an afterimage region corresponding to the saturation region from the second frame, calculate motion information of the afterimage region based on motion information indicating motion between a second frame and a third frame, extract a candidate region that is matched to the afterimage region in the third frame based on the motion information, and correct the afterimage region based on the candidate region data.
