摘要： In a raster input scanner, an original image is converted into digital image data. A scanning bar having at least one array of photosites is moved relative to the original image, whereby the photosites are sequentially exposed to light within a range of intensities reflected from locations on the original image. Each of the image signals from the photosites is integrated as the scanning bar moves relative to the original image, some signals being integrated for a first duration to yield a long-integration image datum, and some signals being integrated for a second duration shorter than the first duration to yield a short-integration image datum. One of the long-integration image datum and the short-integration datum is selected for each location in the original image, depending on the intensity of light associated with the location in the original image.

摘要： 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.

摘要： An adaptive thresholder of the fractional average context type for processing image pixels in which an offset potential, which is used in conjunction with the image potentials of the nearest neighbor pixels to provide an updated threshold potential, is obtained on a pixel by pixel basis as a function of the pixel white peak and black valley potentials. The white peak and black valley potentials are compared with the image potential of each pixel being processed and with predetermined minimum white and maximum black potentials to provide updated white peak and black valley potentials for use in updating the offset potential during processing of each pixel.
