Abstract:
A light sensing element having two functions is provided for a high-speed image scanning system to scan a document, including a set of matrix light-sensing cells for detecting a scanning location for the scanned document, thereby feeding the sensed signals to control the scanning location and scanning speed, and at least one set of trilinear light-sensing cells for sensing an document, thereby acquiring image signals.
