Abstract: An electronic endoscope apparatus has an arrangement that its discrimination circuit discriminates the type or the operational state of the light source in accordance with a discrimination signal transmitted from a discrimination signal generator, and in accordance with the result of the discrimination, the processing operation to be performed by its video signal processing circuit is changed over to correspond to the difference in the type or the operational state of the light source. The video signal processing circuit performs a proper signal processing operation to correspond to the difference in the type of the light source to prevent deterioration in the image quality. The electronic endoscope apparatus is structured so that a different type light source can be adaptably connected to it.

Abstract: In an electronic endoscope apparatus each of the signals of a plurality of systems output from at least one solid state imaging device is judged by a signal monitoring device as to whether it is normal or not. On the basis of the judged result, the processing mode corresponding to each of the signals of the plurality of systems is changed and each signal is processed. If an abnormality occurs, an observed image with which the endoscope inspection can continue will be secured to be safe. Further, in the electronic endoscope apparatus, when the output signal from the solid state imaging device is judged to be abnormal, the amount of illuminating light will be attenuated, the danger by the excessive amount of illuminating light will be avoided and the safety of the person being monitored will be secured.

Abstract: There is provided a frozen picture memorizing memory holding as a frozen picture image a picture image signal imaged by an electronic endoscope. By the operation of a frozen picture directing switch, whether the frozen picture is adapted to the memorizing condition or not is judged through a picture image movement detecting circuit. In case it is judged to be adapted to the memorizing condition, the picture image signal is memorized actually as a frozen picture image to obtain a clear frozen picture having little color smear and fogging.
