Abstract: In a display device with optical sensors, a mode control portion (24) determines a mode to be a normal mode in which to operate a recognition processing portion (22) or a standby mode in which to stop the recognition processing portion (22) from operating. In transition from the normal mode to the standby mode, a decimated image memory (25) stores a decimated image having a smaller number of pixels than a scan picture. The mode control portion (24) performs pixel-by-pixel comparison between the stored decimated image and an image supplied anew, which is obtained by averaging decimated images for two consecutive frames, and causes transition from the standby mode to the normal mode when the number of pixels whose difference in pixel values is greater than or equal to a first threshold is greater than or equal to a second threshold. As a result, it is rendered possible to inhibit erroneous determination and promptly detect a touch position after a quick exit from the standby mode.
