Abstract
A video-signal processing device is connectable to an electronic endoscope designed to output at least one kind of video signal, and comprises a character-information signal producer for producing a character-information signal on the basis of character-code data, and an adder for adding the character-information signal to the video signal outputted from the electronic endoscope, whereby the video signal carrying the character-information signal is fed outside from the device. When the endoscope further outputs a control signal in response to a turning-ON of a function switch thereof, the device comprises a memory for storing fixed character-code data; and a memory-reader for reading the fixed character-code data from the memory in response to the control signal outputted from the endoscope. The character-information signal producer produces a fixed character-information signal on the basis of the fixed character-code data read from the memory.
