Abstract
In a photosensitive imaging apparatus having multiple chips, each chip having a set of photosensors, chips of a single basic design can be instructed to operate consistently with either parallel or serial readout of the apparatus. Signals on a shift register line associated with each chip are recognized, by on-chip circuitry, as an instruction to operate the chip in either a parallel or a serial manner.
Claims7
A photosensitive apparatus, comprising:
- a plurality of photosensors;
- an output line;
- a shift register line for accepting signals over time;
- a shift register for causing an output of signals from the photosensors onto the output line as a result of signals on the shift register line;
- and
- readout control means for recognizing a instruction signal and reading out signals on the output line in one of a parallel manner or a serial manner in response to said instruction signal.
