    摘要： In a display device, a signal level detection circuit detects RGB signal levels for each pixel from an image signal, and then a control circuit detects an area using a gray scale of a single color based on RGB signal levels for each pixel. A first color conversion circuit carries out an image correction on an image signal while a second color conversion circuit carries out another image correction-on an image signal. An H/V position control circuit extracts an image signal of an area detected by the control circuit from an image signal subjected to the image correction of the second color conversion circuit. An image superposition circuit superposes the image signal extracted by the H/V position control circuit with the image signal subjected to the image correction of the first color conversion circuit, thus displaying the superposed image signal on a display.

    摘要： In order to automatically distinguish a type of cable connected to a display apparatus, and transmit appropriate specification information to a host, when a host 10 and a display apparatus 100 are connected via a DVI-D to DVI-D cable 14 for digital signal, a DDC 5V from the host is applied to an emitter of a detection transistor 19, and a lower voltage due to a resistor 17 is applied to its base so that the detection transistor turns on. A collector voltage thus becomes an H level so that a multiplexer 21 is switched to the side of a non-volatile memory 23 in which a digital EDID is stored. When they are connected via a D-Sub to DVI-I conversion cable 15 for analog signal, a DDC 5V terminal and an HPD terminal of the cable are short circuited, so the detection transistor turns off, the collector voltage becomes an L, and the multiplexer is switched to the non-volatile memory side in which an analog EDID is stored.
