Abstract: An image input terminal synchronously transfers image data to an image processing system when the effective image data generation rate of the image input terminal exceeds the throughput rate of the image processing system. The image input terminal scans the document at a constant rate, but the constant rate is slower than the normal scan rate for the image input terminal, thereby effectively scanning the document at a higher resolution. To realize an effective image data generation rate equal to the throughput rate, the image input terminal periodically discards D scanlines or skips N-D scanlines of valid image data to give the image processing system ample time to complete the processing of valid image data. The image input terminal, to facilitate a synchronous transfer of image data, will skip D scanlines of valid image data out of N scanlines of valid image data.

Abstract translation: 当图像输入端的有效图像数据生成速率超过图像处理系统的吞吐率时，图像输入端子将图像数据同步地传送到图像处理系统。 图像输入端以恒定速率扫描文件，但是恒定速率比图像输入端的正常扫描速率慢，从而以更高的分辨率扫描文档。 为了实现等于吞吐率的有效图像数据生成速率，图像输入端周期性地丢弃D个扫描线或跳过有效图像数据的N-D个扫描线，以给图像处理系统充足的时间来完成有效图像数据的处理。 为了方便图像数据的同步传输，图像输入端将跳过有效图像数据的N条扫描线中的有效图像数据的D扫描线。

Abstract: An image processor, for example a digital color copier, receives an image signal transmitted in one of a plurality of different modes to process an image of one picture. An analyzer determines the processing mode of the received image signal. A first processor is selected for sequentially processing the image signal for one picture a line at a time in accordance with the analyzer determining one processing mode was received. A second processor is selected and receives the whole image signal for one picture for processing as a block in accordance with the analyzer determining a different mode was received. A processed image is output from the processor selected by the analyzer.

Abstract: A method and apparatus for color separation scanning wherein a workpiece is movably supported and scanned by a linear detector. At least one color filter is interposed in the optical path between the workpiece and the linear detector and multiple scans are taken of a linear portion of the workpiece. The data obtained from multiple scans are averaged and stored in memory.

Abstract: A raster scanner with linear scanning array, a scanning slit permitting the array to view a document image one line at a time, and document transport for transporting documents past the scanning slit. To accommodate the disparity between scanning rates and user data rates, a relatively small buffer stores lines of pixels output by the array pending user demand. Intermittent operation of the scanner in response to buffer pixel demands is effected through starting and stopping of the document transport. A control is provided to prevent uneven spacing of scan lines resulting from scanning stopped documents or documents in the process of being accelerated or decelerated to and from scanning speed by the document transport.

Abstract: In a printing system, intermediate data in a rendering-standby state can be rendered before intermediate data of an entire page is accumulated in a printing apparatus. A printer driver of a host computer sequentially converts a plurality of rendered objects of each page generated by an application to rendering commands of each page which can be interpreted by the printing apparatus. Every time a rendered object that should be rendered last in each of a plurality of bands, which are defined by dividing a page by the printing apparatus, is detected, the printer driver converts the rendered object that should be rendered last to a rendering command and notifies the printing apparatus of end information indicating the end of processing of the corresponding band.

Abstract: A camera module compresses image data and produces a thumbnail image of this image data in FIFO order (First In First Out) by several lines of the image so as to enable transmission of the image data to the host module while significantly decreasing the size of the frame buffer memory. This can be achieved by, for example, an electronic device, including: a camera module, which transmits the data acquired by photographing; and a host module, which receives the data; wherein the camera module alternately transmits a compressed small portion including the data made by compressing the small portion of the image data for one frame and a sub small portion including the data with the resolution of the small portion reduced.
