Abstract:
An XY address scanning-type imaging apparatus, such as a CMOS imaging apparatus, having a high-speed shutter which is capable of reducing fluorescent-lamp flicker components and which enhances electronic camera-shake correction. 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.
