An endoscope apparatus includes: e.g., an image pickup device including an effective pixel region and an ineffective pixel region, a signal transmission cable that transmits an output signal from the image pickup device, an analog front-end circuit that samples the transmitted output signal and converts a resulting output signal into a digital signal, and a timing generator that generate first and second image pickup drive signals for driving the image pickup device in first and second image pickup device drive modes using horizontal transfer clocks having different frequencies, respectively, and when the first image pickup device drive mode is switched to the second image pickup device drive mode, a control circuit adjusts a timing for a timing generator to generate the second image pickup drive signal. |
