Abstract
A digital camera includes a CCD imager mounted at a front with a primary color filter. An optimal shutter speed is calculated based on a camera signal outputted from the CCD imager upon a pre-exposure. Where a calculated optimal shutter speed is low, a timing generator drives the CCD imager by a pixel-mixing scheme. Charges are first read out of part of the light receiving elements and transferred in a vertical direction. When the charges are transferred by a predetermined distance, the remaining part of the light receiving elements are read out. As a result of this, the charges of a same color of color components are mixed together. That is, a filtering process is effected within the CCD imager to remove aliasing components.
