Abstract:
1. A solid-state image sensing device comprising: a pixel array having a plurality of imaging elements arranged in a matrix; a row selection circuit for selecting a row in the pixel array; a plurality of analog-digital converters which are disposed in respective columns in the pixel array and convert image analog signals read out from imaging elements selected by the row selection circuit into image digital signals; a plurality of signal holding circuits for holding the image digital signals converted by the analog-digital converters in respective columns in the pixel array; and control signal generation units for generating control signals for controlling timings of transfer of the converted image digital signals from the analog-digital converters to the signal holding circuits, wherein the control signal generation units are provided for respective groups into which the analog-digital converters and the signal holding circuits disposed on one side of the pixel array are divided, and generate the control signals of different timings, for respective units including at least one group, of transfer of the converted image digital signals to the signal holding circuits from the analog-digital converters operating in parallel, wherein the solid-state image sensing device switches among the control signal generation units for generating the control signals for the respective units including at least one group, and the control signal generation units generate the control signals of different transfer timings for the respective units including at least one group, and wherein the control signal generation units include first to fourth logic circuits for generating the control signals by performing logic operations on a transfer signal for starting processing for transferring the converted image digital signals from the analog-digital converters to the signal holding circuits and first and second selection signals for selecting among the groups, and based on the selection signals, the solid-state image sensing device switches among the first to fourth logic circuits for generating the control signals of different transfer timings among the groups provided with the first to fourth logic circuits respectively.
