1. A photosensor chip comprising: a first set of photosensors comprising an edge pixel and an interior pixel; and, a control portion for accepting a first external integration signal, said first external integration signal causing an edge pixel integration signal and an interior pixel integration signal for said first set of photosensors, said control portion comprising: a first signal adjuster effectively altering said first external integration signal to cause said edge pixel integration signal and said interior pixel integration signal for said first set of photosensors said first signal adjuster accepts an edge pixel datum instructing said first signal adjuster to cause said edge pixel integration signal to be different from said first external integration signal by a predetermined edge pixel duration, said predetermined edge pixel duration being related to said edge pixel datum, and said first signal adjuster accepts an interior pixel datum instructing said first signal adjuster to cause said interior pixel integration signal to be different from said first external integration signal by a predetermined interior pixel duration, said predetermined interior pixel duration being related to said interior pixel datum.
