摘要： 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 scanned by the scanning array is larger than the block of lines printed by a printing array so that there is 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.

摘要： A method and apparatus for processing image information. An address designation or token is applied to each pixel or data byte in a scan line of image data describing its position in the scan line. By providing each data byte of image information with an address token defining its specific position in the scan line, the image information for data byte on the image is specifically located in the final image configuration, without requiring storage of the entire image information for manipulation. Operation on both data and address token is possible for image manipulation routines.

摘要： An image processing system for altering the size of an image represented by a plurality of input video signals including a controller for producing a scale factor and a scale factor valid signal. The controller also includes a padder which is used to increase the accuracy of the scale factor during the operation of the controller. The signals generated by the controller are passed to an interpolator suitable for producing an output signal as a function of one or more of the input video signals in response to the scale factor and scale factor valid signal.

摘要： Method and apparatus to increase the range of correction of photosite offset and gain response. Each photosite is provided with a correction value for offset and gain response based on measured light intensity value, which is stored in memory. Each photosite correction value is also provided with an attribute value which indicates whether the correction values are to be used as stored, whether a shift of the values is appropriate, in accordance with a stored shift value, or whether the photosite is noncorrectable, and accordingly requires the implementation of a bad pixel routine. Depending on the attribute value, logic is enabled to vary the correction values in accordance with a stored routine for shifting the stored correction value, or implementing a bad pixel routine. If the attribute requires a shifted value, the correction value is shifted a number of places in accordance with a shift stored in the decoder, before it is applied. If the attribute indicates that the photosite response is not correctable, a bad pixel correction routine is enabled, to produce substitute data.

摘要： A method and apparatus for processing a scan line of image data, wherein image data from portions of the scan line is processed simultaneously along plural channels, each channel processing a portion of the image data, and provided with context information from an adjacent portion of the scan line. Context pixels are added at the trail edge of a first scan line portion, derived from the lead edge of a second scan line portion. In certain image processing requiring preceding and succeeding pixel context information, subsequent to processing, on correctly processing pixels are transferred for subsequent processing, and pixels at the trail edge of a first scan line portion, and the lead edge of a second scan line portion are not transferred, leaving complementary scan line portions.

摘要： Method and apparatus for processing a stream of image pixel data to determine the presence of high frequency half-tone data. The arrangement applies the function ##EQU1## to a stream of image pixel data. The presence of minimums of .phi.(k) at times indicative of predetermined half-tone image frequencies is detected and an output signal indicative of the presence or absence of minimums at the predetermined half-tone image frequencies is provided. More particularly, the two's complement of the stream of image pixel data is added to each of a plurality of differently delayed signals derived from the original stream of image pixel data. The absolute value is taken of the resulting function. The signal is summed for a selected number of pixels, corrected for noise, and reviewed for minimums. Minimums occurring at selected positions in the pixel stream indicate certain frequencies of the data. An output is created based on frequency indications.
