    Abstract: A triggering system and process for a form reader is shown using a histogram of the optical scene. The form reader is open on three sides with a camera facing a platen on to which a form is placed. The camera converts the light rays reflected from the platen into a video stream that is sent to a processor. A change in content of a first light intensity level contrasted to the content of a second light intensity level is used to determine when the form enters the scene. Illustratively, the first light intensity level represents black levels and the second light intensity levels represent white levels. A threshold is pre-determined that isolates the first light intensity content, and when the first light intensity content remains constant (after the presence of a form) the form is deemed to be still wherein the system may then read the information on the form.

    Abstract: The boundaries of a scanned digital document are determined by identifying the largest connected component in the received digital document and assigning the boundaries of the largest connected component as the boundaries of the received digital document or by using a row by row and column by column analysis of the received digital document to identify horizontal and vertical bands in the digital image having pixels with a value opposite to the value of pixels of a background of the received digital document and assigning the horizontal and vertical bands to be the boundaries of the received digital document. These processes may be performed in series or parallel by a processor associated with a scanner that creates the digital document.

    Abstract: Pixel circuits in an image sensor are sampled repetitively during an image frame period. At each sampling, a signal indicative of the photocharge integrated by a pixel circuit since last reset is compared to a threshold. If the integrated photocharge signal has not reached the threshold, the pixel circuit is permitted to continue integrating photocharge. If the integrated photocharge signal has reached the threshold, the pixel circuit is reset to remove integrated photocharge and photocharge integration for that pixel circuit is restarted. A corresponding pixel circuit value is recorded for the reset pixel circuit.
