In an XY address scanning-type imaging apparatus, such as a CMOS imaging apparatus, a high-speed shutter which is capable of reducing fluorescent-lamp flicker components and which is required for electronic camera-shake correction can be realized. When the vertical synchronization frequency is denoted as fv (Hz) and N is a positive integer, the shutter is set to N/120 seconds when 120/fv is an integer, and the shutter is set to N/100 seconds when 100/fv is an integer. In the NTSC system, when camera-shake correction is ON, the shutter speed is set to {fraction (1/120 seconds, and when camera-shake correction is OFF, the shutter speed is set to {fraction (1/60 seconds. In the PAL system, when camera-shake correction is ON, the shutter speed is set to {fraction (1/100 seconds, and when camera-shake correction is OFF, the shutter speed is set to {fraction (1/50 seconds. The same applies to the progressive system.
