PROBLEM TO BE SOLVED: To enable detecting difference in characteristic for each signal path in an imaging element of a multi-channel output type having a uniformized structure. SOLUTION: The imaging element has pseudosignal generating means 25-28 for generating pseudo video signals, pseudosignal reading means 21-24 for reading the pseudosignals from the means 25-28 and outputting them, and a level control means 29-32 for controlling the level of the signals outputted from the means 21-24.
