PURPOSE:To realize the display device in which an image is adjusted with very excellent operability without incurring a high product cost. CONSTITUTION:A remote controller 1 generates operation information in response to the setting operation and superimposes the operation information onto an optical signal and provides an output, a light receiving section 2 receives the optical signal to decode the On the other hand, information and a microcomputer 3 generates an adjustment signal corresponding to the operation information. Then a D/A converter circuit 4 converts the adjustment signal into an analog signal, and a correction circuit 5 generates a correction signal corresponding to the analog adjustment signal and applies the correction signal to a CRT peripheral circuit. As a result, since various picture adjustments are attained depending on the setting operation of the remote controller 1 being a separate device from the main device, the image is adjusted with very excellent operability without incurring a high product cost. |
