    Abstract: An endoscope system includes: an image pickup device for picking up an object image; a drive control circuit for initializing and driving the image pickup device; and a monitoring portion for detecting abnormality of an image pickup signal from the image pickup device and outputting an initialization start signal to the drive control circuit. The monitoring portion compares a synchronization code, an optical black pixel value and an effective pixel value of the image pickup signal with respective thresholds indicating a normal range and a stipulated number of times or a stipulated number of pieces, and in a case of detecting abnormality of one of the synchronization code, the optical black pixel value and the effective pixel value, outputs the initialization start signal to the drive control circuit, and the drive control circuit initializes the image pickup device in a case of receiving the initialization start signal the monitoring portion.

    Abstract: An endoscope system includes a head portion, a connector portion and a CCU. The head portion includes a test signal generating portion configured to generate a first test pattern signal. The connector portion includes: a test signal generating portion configured to generate a second test pattern signal which is a same pattern signal as the first test pattern; a first comparison circuit configured to output a comparison result of comparing the first test pattern signal with the second test pattern signal; and a test signal generating portion configured to generate a third test pattern signal. The CCU includes: a test signal generating portion configured to generate a fourth test pattern signal which is a same pattern signal as the third test pattern; and a second comparison circuit configured to output a comparison result of comparing the third test pattern signal with the fourth test pattern signal.

    Abstract: An endoscope apparatus includes image sensors, a power supply unit, a failure detection unit, and a controller. The power supply unit supplies power independently to the image sensors. The failure detection unit detects a failure in each of the image sensors. The controller controls the power supply unit to stop power supply to an image sensor in which a failure is detected at the failure detection unit.
