Solid-state image sensing device having signal holding circuits for holding image digital signals converted by analog-digital converters
Abstract:
A solid-state image sensing device according to the invention which can reduce an instantaneous current occurring in transferring image digital signals from analog-digital converters to registers to reduce noise sneaking into the analog-digital converters and a pixel array includes a pixel array, a vertical scanning circuit, a plurality of column ADCs, a plurality of registers, and control signal generation units. The control signal generation units are provided for respective groups into which the column ADCs and the registers disposed on one side of the pixel array are divided, and generate control signals of different timings, for respective units including at least one group, of transfer of converted image digital signals to the registers from the column ADCs operating in parallel.
