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.
