Abstract:
A photosensitive apparatus, such as a scanner used in a digital copier, includes a plurality of photosensor chips. Each photosensor chip comprises a first set of photosensors, and a control portion for accepting an external integration signal, the signal causing an integration time for the set of photosensors. A signal adjustor is associated with the control portion, and effectively alters the external integration signal to cause the control portion to cause a modified integration time for the first set of photosensors. The system enables adjustments of integration times among chips within an apparatus sharing a common control line.
