Dispositif d'imagerie et procédé de réduction du scintillement

Imaging apparatus and flicker reduction method

Abstract

An XY address scanning-type imaging apparatus, such as a CMOS imaging apparatus, provides a high-speed shutter which is capable of reducing fluorescent-lamp flicker components and electronic camera-shake correction. A controller for controlling the electronic shutter speed is provided, the shutter which is operable to set the shutter speed 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 where the vertical synchronization frequency is denoted as fv (Hz) and N is a positive integer. In the NTSC system, when camera-shake correction is ON, the shutter speed is set to 1/120 seconds, and when camera-shake correction is OFF, the shutter speed is set to 1/60 seconds. In the PAL system, when camera-shake correction is ON, the shutter speed is set to 1/100 seconds, and when camera-shake correction is OFF, the shutter speed is set to 1/50 seconds. The imaging apparatus may also be applied to a progressive scanning system.
