Abstract

PURPOSE:To update the next luminance signal to be displayed, in a short time, by designating an address of a video memory in which a luminance signal has been written, and erasing only the luminance signal of this address. CONSTITUTION:Analog input signal is written temporarily in a stream memory 31 through an A/D converter 2. A video memory address controller designates X and Y addresses of a video memory 5 by a data supplied from the memory 31, and stores a luminance signal from a luminance signal generating circuit 101 in the memory 5. This luminance signal is read out by an output of a monitor synchronizing signal generating circuit 11, and is displayed on a raster scan monitor 6. On the other hand, when a control signal S5 is LOW, readout and erase address controllers 14, 15 read out a display data of 1 frame before and the next data to be displayed, alternately from the memory 31, erase the luminance signal of 1 frame before, write the luminance signal to be displayed next, and display a biological phenomenon waveform.
