ABSTRACT:
The present invention is a digital imaging system for a copier that comprises a full-frame, two-dimensional sensor array to capture a document's image and a full-frame output light valve with backlight to flash expose the image onto a photoreceptor belt. The document is flash exposed to illuminate the page and the full-page image is captured by the full-frame, two dimensional sensor array. The sensor array then reads out the digital image data in response to a driver. The data is then input into the full-frame digital output light valve. The driver provides for the synchronous control of the system. Optionally, an electronic subsystem may perform digital image processing according to user demand--before the data arrives at the output light valve. After image processing (if any), the digital data, supplied to the full-page output light valve, forms a pattern on the display according to the data. The patterned image is then flash exposed by a backlight, through the light valve, and onto a photoreceptor.
