Abstract
An improved image sensing module disclosed herein has particular applications in imaging systems, such as image scanners, copy machines and facsimile machines, that optically convert an object to a signal or image before other processes can be proceeded. In one embodiment, the image sensing module employs a control signal circuitry that is integrated in an image sensor. The control signal circuitry receives a predetermined period for the light integration process of the image sensor and produces a sensor control signal that includes a time parameter that ensures that the light integration process lasts exactly for the predetermined time regardless how long an illumination source is kept on.
