摘要： In a full-color image scanner having three parallel linear arrays of photosensors, each linear array of photosensors is sensitive to one primary color. With each readout cycle relating to a row of small areas on an original image moving past the scanner, the middle array of the three arrays of photosensors reads out its video data before the other two. This technique allows the arrays of photosensors to be spaced relatively close to each other, and in turn the close spacing of photosensors requires relatively fewer scan lines of video data to be temporarily buffered in the readout process.

摘要： An image sensor array includes a plurality of photosensor chips, which are butted end-to-end to form a single linear array of photosensors. Each individual chip in the array is provided with an independently-addressable output enable line and video output line. This configuration allows individual chips to be addressed to output image data at specific times and in a specific manner suitable for any kind of downstream circuitry.

摘要： A photosensitive imaging apparatus has a linear array of groups of photosensors. In a low-resolution scanning mode, all of the photosensors in each group act together as one large photosensor. In a high-resolution scanning mode, each photosensor in a group acts outputs image-based signals independently. In either mode, the signals output by the photosensors are transferred to one of two output lines, such as for “odd-” and “even-” positioned photosensors or groups of photosensors. The signals on the two lines can then be multiplexed to a single output line. The dual output lines enable fast signal output in either resolution mode.

摘要： A test circuit incorporated as part of an image sensor array having a plurality of image sensors and associated transfer circuits includes a test line associated with each photosensor. In a test mode, a signal output from a photosensor can be substituted with a predetermined voltage from an external source. By providing a predetermined test voltage to the transfer circuits and then reading out signals from the transfer circuits, faults in the transfer circuits can be isolated from faults in the photosensors.

摘要： A full-color scanning array uses CMOS active pixel cells, or photogates, as photosensors. A set of photogates, each photogate being specifically filtered for one primary color, is associated with a common node. A clearing gate downstream of the common node applies a relatively high potential to a selected photogate, for the purpose of clearing any charge from the photogate. In this way, the integration time for the photogate can be started at a precise time, and the effective exposure time of each photogate can thereby be precisely controlled. Alternately, one of the set of photogates can be repeatedly cleared without a signal being read therefrom, allowing the array to operate in a monochrome mode.

摘要： In a CMOS-based photosensor chip, the area between the last photosensor in a linear array of photosensors and the edge of the chip can be a source of unintended charge generation affecting the last photosensor. A guardring, in the form of a biased diffusion area, prevents the unwanted leakage of charge from the edge area to the end photosensor.

摘要： A CMOS-based photosensor array, having a plurality of photodiodes therein, includes a spillover protection circuit associated with each photodiode. The spillover protection circuit causes a potential to be applied to a photodiode in response to a charge spillover or “blooming” condition. The spillover protection device is momentarily disabled whenever a bias charge is injected onto the photodiode by the transfer circuit. Also, a reference voltage applied to the gate of a transistor forming the spillover protection device is higher than a threshold voltage of the transistor but is lower than a sum of the threshold voltage and a maximum light-intensity signal from the photodiode.

摘要： In an image sensor having a plurality of photodiodes, subsets of photodiodes share a common node for signals to be sent to an amplifier. Within each subset, each individual photodiode is selected for sending signals to the amplifier by an associated selection device. The selection device is a MOS device operating in a linear region. The subset of photodiodes share a common “fill and spill” or “bucket brigade” transfer circuit to the amplifier, the transfer circuit including at least one MOS device which operates in a subthreshold region.

摘要： In an image sensor array, as would be used in an input scanner such as in a digital copier, an original image is moved relative to a linear array of photosites. Each photosite includes at least two wide photosensors, each of which extends substantially across the photosite along the array direction, and at least two narrow photosensors, which are arranged next to each other along the array direction. In one embodiment, the wide photosensors include primary-color filters and the narrow photosensors are clear-filtered.
