To prevent the occurrence of flickering at photographing under a conventional fluorescent light by obtaining an automatic exposure(AE) evaluation value from a digital video signal which is obtained from photographing an object and selecting plural shutter speeds from among specific shutter speeds, based on the AE evaluation value.

A CPU 121 uses a RAM as work regions in accordance with a program stored in a ROM and controls photographing, AE and automatic white balance or the like from an instruction or the like from an operating part 123. The CPU 121 controls the shutter speed and the variable gain so that the AE evaluation value reaches a reference value in the AE control. Furthermore, a variable gain amplifier 105 corrects an output signal level of a correlation double sampling circuit 104. Here, the CPU 121 obtains the AE evaluation value, based on a digital video signal obtained through photographing an object and selects at least two shutter speeds from among the shutter speeds which are integral multiples of 1/100 sec, based on the AE evaluation value.
