When a new processor is connected to an old electronic endoscope provided with a memory storing B data for image processing specific to the scope, white balance control is carried out by a microcomputer. That is, at the time when power is turned on, this microcomputer determines whether or not image processing data compatible with the new processor is present in the old electronic endoscope. If the compatible data are not present, the microcomputer carries out white balance control based on the image of white board picked up by the user, and additionally writes new C data for image processing at the time of white balance control in a memory of the old electronic endoscope together with data identification information. Thereby, the compatibility with an old type of electronic endoscope is maintained.
