Abstract: An image size control system for controlling the size of the image produced by pixels generated by a raster scanner. A binary rate multiplier is used for image size control along the X-axis, the multiplier being programmed to the size image desired to vary the frequency of the pixel clock signals output by the multiplier. A control flip-flop astride the image pixel stream is driven by the multiplier clock signals to speed up or reduce the rate at which image pixels are output with consequent change in image size along the X-axis. For image size control along the Y-axis, a phase lock loop speed controller is provided for the scanning carriage drive motor with programmable frequency generator. The frequency output of the generator is settable to the image size desired, changes in image size being achieved either by increasing or decreasing the rate at which the scanning carriage is moved.

Abstract: SCANNING APPARATUS A line scanning apparatus employing a multiplicity of linear arrays, the linear extent of which is less than the length of the scan line. To permit an entire line to be covered, the arrays are offset from one another in the direction of scan with adjoining array ends overlapped. To correct for the misalignment and redundancy introduced, the image data from the arrays is buffered until a line is completed when readout, is initiated. During readout, cross over from one array to the next is effected within the overlapped areas and the redundant data discarded.

Abstract: Pixel magnification/demagnification apparatus and method are disclosed for controlling the size of reproducible image, the image being represented by video image signals or pixels generated by a raster scanner (12). A binary rate multiplier (102) is used for image size control along the X-axis, the multiplier being programmed to the size image desired to vary the frequency of the pixel clock signals output by the multiplier. A control flip-flop (45) astride the image pixel stream is driven by the multiplier clock signals to speed up or reduce the rate at which image pixels are output with consequent change in image size along the X-axis. … For image size control along the Y-axis, a phase lock loop (86) control with programmable frequency generator (82) is provided for the scanning carriage drive motor (39). The frequency output of the generator is settable to the image size desired, changes in image size along the Y-axis being achieved either by increasing or decreasing the rate at which the scanning carriage (32) is moved.
