ABSTRACT:
An imaging apparatus for focusing a light onto an image to generate an electric signal representing thus focused light image with a broader dynamic range includes an image pickup device, an image pickup device controller, and an accumulating charge selector. The image pickup device control controller controls an amount of electric charge that image pickup device can accumulate therein. The accumulating charge selector switches the image pickup deice to a first accumulative electric charge amount level and to a second accumulative electric charge amount level greater than said first accumulative electric charge amount level within said imaging period.
