Cell classification apparatus capable of displaying a scene obtained by superimposing a character scene and graphic scene on a CRT

摘要

A first video signal is obtained by picking up an image of a sample by a TV camera. A second video signal representing character information regarding the sample is derived from a memory connected to a computer system. The first and second signals are superposed to obtain a sum signal representing a combined single scene, and the sum signal is displayed as a visible picture on a display device. Before the step of superposition of the first and second video signals, at least one of the video signals may be multiplied by a weight.
