摘要： A scanning order calculating portion (23) included in a display control circuit (200) determines the order of selecting all rows by repeating the following: the row for which the total amount of potential variation relative to a reference row is the lowest is selected as a subsequent row, and the row having been selected as the subsequent row is used as the next reference row in a similar operation to determine the next row to be set as a subsequent row. A scanning order setting portion (24) controls an address outputting portion (26) such that the scanning signal lines are selected in the determined order, and also controls digital image signals DV outputted by output frame memory (22). Power consumed by driving video signal lines can be reduced by selecting the scanning signal lines in such an order that the total amount of potential variation of the video signal lines becomes smaller.

摘要： By reducing the potential drop of a storage node that occurs due to feedthrough, the capacitance of a storage capacitor is reduced and sensor sensitivity is improved. In a photosensor, the first terminal of a storage capacitor (C2) and the gate of a MOS transistor (M1), which outputs a signal in accordance with the potential of a storage node (N2), are connected to the storage node (N2). A forward biased pulse voltage is supplied to the anode of a first photodiode (DS) in a reset period, and a reverse biased voltage is supplied to the anode of the first photodiode in a storage period and a readout period. A reverse biased voltage is supplied to the anode of a second photodiode (DM) in all operation periods. A voltage that keeps the potential of the storage node lower than the threshold value of the MOS transistor (M1) is supplied to the second terminal of the storage capacitor in the reset period and the storage period, and a voltage that thrusts the potential of the storage node (N2) upward to the threshold value of the MOS transistor (M1) or higher is supplied to the second terminal of the storage capacitor in the readout period.
