ABSTRACT:
An electronic still camera requires a solid-state image sensing apparatus capable of providing a higher-speed pickup image signal having a high vertical resolution. In a line reducing operation to reduce the number of lines of the pickup image signal to be output by applying read-out pulses to read-out gate units located at predetermined intervals in order to read out only signal electric charge from sensor units for picture elements arranged in the vertical direction on some lines, a vertical CCD is driven by a combination of a pair of vertical transfer clock signals .o slashed.V1 (.o slashed.V1') and .o slashed.V3 (.o slashed.V3') having phases opposite to each other and another pair of vertical transfer clock signals .o slashed.V2 and .o slashed.V4 also having phases opposite to each other, allowing the overlap period twice the vertical transfer clock signals to be lengthened.
