Document Type and Number:
Japanese Patent JP3041099
Kind Code:
B2
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.
