An endoscope includes: a CDS circuit that samples an image pickup signal from a CCD via a feedthrough sampling pulse SHP and a clamp pulse SHD to output a post-sampling image pickup signal; a CPU that controls a sampling timing of each of SHP and SHD and evaluates the post-sampling image pickup signal from the CDS circuit, and a flash memory that stores timing information on the respective timings and timing determination procedure information. The CPU, upon receipt of an adjustment instruction for adjustment of the respective timings of SHP and SHD, rewrites the timing information in the flash memory according to a result of evaluation of a plurality of post-sampling image pickup signals obtained by shifting the respective timings based on the timing determination procedure information.
