Abstract:
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 starts simultaneously with said second period, is shorter than said second period and is overlapped in time with said second period, said digital camera further comprising a first applier to apply a first charge read pulse to said first light-receiving elements, a second applier to apply a second charge read pulse to said second light-receiving elements, a third applier to apply a single charge sweep-out pulse to both said first light-receiving elements and said second light-receiving elements, and a shutter member to mechanically cut off incident light on said light-receiving surface, wherein said first exposer controls any two of said first applier, said third applier and said shutter member to carry out the first exposure while said second exposer controls any two of said second applier, said third applier and said shutter member to carry out the second exposure, and wherein said first exposer controls start and end time points of the first exposure by said first applier and said shutter member, respectively, and said second exposer controls start and end time points of the second exposure by said third applier and said shutter member, respectively.
