ABSTRACT:
The pixel number control device has a correlated double sampling (CDS) circuit by which the number of pixel signals outputted from a CCD are controlled. In the record mode, in which a still image corresponding to the pixel signals is recorded in a recording medium, all of the pixel signals are outputted from the CDS circuit. In the monitor-through mode in which a moving image corresponding to the pixel signals obtained by the CCD is indicated by a liquid crystal display, a part of the pixel signals is subsampled and is not outputted from the CDS circuit.
