摘要： The present invention is a method and system for mixed resolution, multi-channel color image processing including compression, transmission and decompression. The color information is defined at a lower resolution since colors generally do not change at a high frequency and higher compression ratios may be obtained with the lower resolution. The edge information contains the commands switch between the foreground and background colors. The edge information occurs at high resolution and high frequency rates relative to the color information. The lower resolution color planes can be pixel replicated to the resolution of the edge information after compression and decompression for proper edge selection to occur. The resulting reconstructed image of foreground and background colors retains high detail.

摘要： An apparatus derives data to enable a fill action during operation of a print device along a scan line. The apparatus includes a processor which determines, for each of a sequence of contours of a glyph, point of intersection values between a scan line and the contours. The sequential point of intersection values indicate OFF-to-ON and ON-to-OFF transitions required of the print device. Sequential OFF-to-ON and ON-to-OFF transitions comprise a transition pair. The apparatus includes a memory comprising 2N storage positions for storage of N transition pairs. Comparator circuitry is coupled in parallel to the 2N storage positions. A controller operates the comparator circuitry to determine an order of all OFF-to-ON point of intersection values and an order of all ON-to-OFF point of intersection values in the 2N storage positions. Switch circuitry is responsive to the determined order of OFF-to-ON point of intersection values to re-order the OFF-to-ON point of intersection values in the 2N storage positions and is further responsive to the determined order of the ON-to-OFF point of intersection values to re-order the ON-to-OFF point intersection values in the 2N storage positions. Overlap regions are determined and transition pairs to be arranged so that overlap regions are ignored.

The transition data is supplied by pulse code logic that converts pixel data to the transition data. The embodiment of an edge placement device includes first edge placement logic coupled to taps from a first clock delay chain and second edge placement logic coupled to taps of a second clock phase delay chain. Also included is a phase splitter that generate a first and a second clock phase coupled, respectively, to the first and the second clock delay chain from a clock corresponding to a pixel time period. The first and the second clock phase have rising edges on alternate cycles of the clock. The first and the second edge placement logic each include a plurality of D flip flops. The clock inputs of each of the flip flops in the first and the second edge placement logic are coupled, respectively, to one tap from first or the second clock delay chain. The D inputs of the flip flops of the first and the second placement edge placement logic are coupled, respectively, to a first and a second data phase provided by the pulse code logic. By setting the values of the first and the second data phases, supplied on alternate cycles of the clock, video data is generated having transitions during the pixel time period corresponding to the pixel data.

摘要： Lower resolution source data is synthesized to a higher resolution format for subsequent rendering on a lower resolution output device. Synthesis occurs by selecting or generating and using a synthesis template that represents a configuration of a plurality of pixel data in the higher resolution format into which the lower resolution source data is to be synthesized. A working or active pixel is identified from the lower resolution source data, a synthesis template is selected, and then the synthesis template pixel data is substituted for the working pixel for rendering on the output device. The synthesized higher resolution data is rendered in a manner such that dots represented by the synthesized data are formed interstitially relative to scan lines of the given lower raster/resolution capability of the output device. The working pixel is identified in the lower resolution data by recognizing a configuration of a plurality of pixel data adjacent the working pixel. The synthesis template comprises at least a two by two cell matrix for pixel placement in the higher resolution format. The synthesis template pixel placement is formed to provide an apparent merge of the pixel data in the higher resolution format with the adjacent pixel data of the lower resolution format data.

摘要： An electrophotographic imaging device uses a transition placement device to position transitions in a stream of video data. A rasterizer included in the electrophotographic imaging device generates pixel data bytes based upon data received from a computer defining an image. A converter generates codes specifying positions of transitions within a pixel time period corresponding to a pixel data byte. The transition placement device includes a phase measuring device to measure a timing offset between an active edge of a beam detect signal and a rising edge of a reference clock. A transition adjustment device adjusts the positions of the transitions specified by the codes relative to the rising edge of the reference clock using the timing offset. Transition generation logic generates the transitions for the stream of video data using the adjusted transition positions received from the transition adjustment device. If the adjusted positions of the transitions shift the occurrence of the transitions to the next cycle of the reference clock, the transition adjustment device determines the position of the transitions relative to the rising edge of the reference clock into which the transitions were shifted. Registers included in a next cycle transition storage device delay the transitions shifted to the next cycle by one reference clock cycle before application to the transition generation logic.
