Digital camera
First Claim
1. A digital camera, comprising:
- an image sensor formed, in a light-receiving surface, with a plurality of first light-receiving elements and a plurality of second light-receiving elements;
a first exposer for subjecting said first light-receiving elements to first exposure for a first period;
a second exposer for subjecting said second light-receiving elements to second exposure for a second period;
an outputter for separately outputting, from said image sensor, a first charge produced in said first light-receiving elements due to the first exposure and a second charge produced in said second light-receiving elements due to the second exposure; and
a generator for generating a still image signal of one screen on the basis of said first charge and said second charge;
wherein said first period is shorter than said second period and overlapped in time with said second period.

Abstract
A digital camera includes a shutter button. When taking a still picture of a subject in response to operation of the shutter button, a TG carries out first exposure and second exposure. The first exposure and the second exposure are simultaneously started by the suspension of outputting a charge sweep-out pulse. Elapsing a first exposure period, the TG reads a first charge out of a part of the light-receiving elements, thereby ending the first exposure. Elapsing a second exposure period, a mechanical shutter is closed thereby ending the second exposure. A second charge produced due to the second exposure is read out after completing the transfer of the first charge. The first and second charges outputted from the CCD imager are combined together by an image combining circuit.
