PURPOSE:To display the image data with large capacity in real time by reading out the superposing objective data in a video memory converting them to digital color information, synchronizing and superposing the digital color information with the moving image data. CONSTITUTION:By a display read-out control circuit 29, the video data are cut and divided, and a color lookup table 31A are addressed successively, and the video data P7-0 are converted to the color specifying data R5-0, etc., to be supplied to a superposing control circuit 27. By an MPU 19, a transmission/ superscription selection signal is supplied to the superposing control circuit 27. The color specifying data are converted by a DAC 31B to be supplied to a CRT 33, and are converted to the display data by a flat pannel control circuit 35 to be supplied to a flat display device 37. By a moving image read-out control circuit 23, the moving image data are read out from the video memory VM to be supplied to a conversion table 25, and are synchronized with the color specifying data from the table 31A to be supplied to a control circuit 27. |
