Abstract: A high density charge coupled device imaging array 58 with a bilinear array 60, 62 of photosites on a single integrated circuit chip is utilized in an image scanning configuration. Offset photosites 60a, 62a in two rows are coupled via transfer gates 64 to storage register 72 and then to two shift registers 74, 76, and via transfer gates 66 directly to two shift registers 68, 70 in a quadrilinear array. The output of these four shift registers 68, 70, 74, 76 are multiplexed to generate a single output pulse train representative of the information scanned.

Abstract: A scanner-printer of the type that scans and prints in blocks, each block consisting of a preset number of image lines, in which the block of lines (SLn-2 to SLn+2) scanned by the scanning array is larger than the block of lines (SLn) printed by a printing array so that there are provided additional image scan lines before and after each block of image lines printed, the additional image scan lines providing image context data for use in processing image signals adjacent the boundaries between blocks of image lines.

Abstract: A photosensitive apparatus in which a photosensitive member defines a photosite of a predetermined area on a surface thereof, the photosensitive member forming electron-hole pairs when the photosite is exposed to light. A collection layer disposed on the photosite encompasses an area of less than the entire photosite.

Abstract: A high density charge coupled device imaging array 88 with a bilinear array of photosites on a single integrated circuit chip is utilized in an image scanning configuration. Offset photosites 90a, 94a in the two separated rows are coupled via transfer gates 98, 106 to storage registers 104,108 and then to two shift registers 110, 112, and via transfer gates 96 directly to two shift registers 100, 102 in a quadrilinear array. The output of these four shift registers 110,102,110,112 are multiplexed to generate a single output pulse train representative of the information scanned. By separating the offset rows 90, 94 of photosites by a row 92 therebetween, the necessity for accurate alignment of the photosite areas is reduced.

Abstract: A full width array spectrophotometer for full width scanning color analysis of color test targets, with one or two substantially linear elongated arrays of closely spaced multiple LED illumination sources of plural different color emissions in a multiply repeated pattern of at least three or four different colors transversely spanning a printer paper path and sequentially illuminated to illuminate a transverse band across a printed sheet moving in the paper path, and a corresponding elongated low cost light imaging bar comprising a parallel and corresponding ly elongated array of multiple closely spaced different color sensitive (three or four rows of color-filtered) photodetectors, which imaging bar is positioned to detect and analyze light reflected from the transverse sequentially illuminated band.

Abstract: 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.

Abstract: Sensor array architectures for both analog and digital sensor arrays adapted for single chip applications or abutment with other like arrays to form a composite scanning array, the architecture providing a sensor array in which the array video signal processing circuits, clock circuits, etc. are integrated onto the same chip as the sensor array itself and dark reference sensors are located in-line or apart from the image scanning sensors to avoid gaps in the scan line when several sensor arrays are assembled together.
