Abstract

PURPOSE: To digitally transmit data without increasing the number of lines in the case of changing the contents of a color lookup tabe memory by allowing source data for changing the contents of the color lookup table memory to interrupt the section of a horizontal synchronizing signal and successively transferring the data to a monitor TV side. CONSTITUTION: In the case of changing the display color of a picture, the source data for rewriting the contents of the lookup table memory 100 is previously stored in a source memory 108 on a computer side, a readout address counter 110 generates an address, and the source data is transmitted to the monitor TV side through a data line 102. On the monitor TV side, a write address counter 118 generates the address to write the source data in the memory 100, and a pulse generation circuit 120 generates a pulse signal to allow the write. Thus, the data is digitally transmitted without increasing the number of lines in the case of changing the contents of the memory 100.
