PURPOSE:To synthesize and process display data of different modes at high speed by selectively outputting one of the two image data at a fixed timing by means of selectors after the two-image data are converted into image element data of the same mode. CONSTITUTION:A priority signal is set at 0. Thus, the selector 12 selects TPA data in a look-up table (LUT) 9 and gives its '1' of '0' signal to the selecting terminal S of the selector 11 as it is. The LUTs 9 and 10 convert the input data on sides A and B into a common mode (resolution), synchronize them and output the data to the selector 11. The selector 11 output color data on the side A corresponding to an object to a display circuit when the TPA data is '0' and color data on the side B corresponding to a transparent background to the display circuit when the TPA data is '1'. When the side B is preferentially displayed by using the side A, the priority signal is set at 1. |
