As will be described later, the horizontal combining unit 40 is constituted with a plurality of switches and combines pixel signals output on the first vertical signal lines VL1 and the second vertical signal lines VL2. The arithmetic units 50 each execute an arithmetic operation to add together signals input thereto via the horizontal combining unit 40. The A/D conversion units 80 convert signals output thereto from the arithmetic units 50 to digital signals and output the digital signals resulting from the conversion to the output unit 90. The output unit 90, which includes a signal processing unit (not shown), executes signal processing including correlated double sampling and signal level correction processing on the signals input thereto from the A/D conversion units 80 and outputs a signal resulting from the signal processing to the control unit 4 of the electronic camera.
