Document Type and Number:
Japanese Patent JP2011250245
Kind Code:

Abstract:

To provide an imaging apparatus capable of obtaining an image in a desired exposure state even if a curtain speed characteristic is varied when a shutter curtain performs a light-shielding operation.

An imaging apparatus comprises: an imaging part for exposing a subject image to generate image information; an electronic shutter control part for controlling the imaging part to start exposure; a mechanical shutter part for regulating the exposure of the imaging part by a light-shielding operation; an exposure time calculation part for calculating exposure time based on a subject image; a shutter operation control part for controlling the electronic shutter control part to start exposure and controlling the mechanical shutter part to start the light-shielding operation based on the exposure time; a judgement part for judging time from the start of exposure by the electronic shutter control part to regulating the exposure by the mechanical shutter part; and an image processing part for correcting the image information generated by the imaging part based on the exposure time calculated by the exposure time calculation part and the judgement result by the judgement part.
