Title:
IMAGING APPARATUS
Document Type and Number:
Japanese Patent JP2014220762
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an imaging apparatus capable of reducing the influence given on the image processing by an adjustment processing of image brightness value when the brightness of an imaging region changes.SOLUTION: An imaging section 11 takes an image in an imaging range at a predetermined frame rate. An amplifier 12 amplifies the brightness value of image data output from the imaging section 11 on each pixel and output the same to the outside. An exposure adjustment section 13 adjusts the exposure conditions of the imaging section 11. A control section 14 adjusts the amplification ratio of the amplifier 12 and the exposure conditions of the exposure adjustment section 13 so that the brightness evaluation value obtained by performing statistical processing on the brightness values of plural pixels in the image data agrees with a predetermined target value. When the brightness evaluation value is within a brightness range where the image data output from the amplifier 12 can be processed, the control section 14 limits the adjustment amount of the exposure conditions and the amplification ratio so that the rate of change of the brightness evaluation value which is generated by the adjustment processing of the brightness value is equal to less than a predetermined standard value.
