摘要： An image is rotated in opponent color space, such as L*a*b* or Y CB CR color space, by inputting the opponent color space image data, subsampling the opponent color space image data, and addressing the subsampled opponent color space image data into an output configuration corresponding to a specified rotation angle. For 90° and 270° rotation, the opponent color space image data is scaled before being addressed. This eliminates distortion of the rotated image, while allowing real-time rotation of the image in hardware.
摘要翻译：通过输入对方的彩色空间图像数据，对对方的彩色空间图像数据进行二次采样，以及寻址二次采样的对象色彩空间图像数据，使图像在对方的颜色空间（例如L * a * b *或Y CB CR颜色空间）中旋转变成对应于指定的旋转角度的输出配置。对于90°和270°旋转，对方的颜色空间图像数据在被寻址之前被缩放。这消除了旋转图像的失真，同时允许图像在硬件中实时旋转。

摘要： A multiplexing bus controller with input conditioning is provided in which the need for a dedicated microprocessor for handling input filtering, input change detection and serial-to-parallel/parallel-to-serial I/O data conversion is eliminated. The controller is realized in a gate array and provides input data oversampling and output refreshing to eliminate random noise coupled to the data lines. In addition, the oversampled data is filtered to debounce the signal received from the input devices. The input data is converted from serial-to-parallel and checked to detect any change from the previous input data stream. Upon detection of an input change, the host microprocessor is interrupted. When the host microprocessor sends data to the bus controller, the bus controller then converts the data to a serial stream for communication to the appropriate output device. Additionally, the bus controller is provided with an internal turnaround circuit to loop back outputs to the inputs for diagnostic purposes. Very low gate counts realized in the design of the multiplexing bus controller allow it to be realized on a single chip.

摘要： A printing system for processing one or more images of a job is provided. The printing system includes a video bus communicating with both a first transfer module and an image processing section. In operation, a first segment of the job is processed in the image processing section while a second segment of the job is buffered in the first transfer module. Subsequently, the first segment of the job is transferred away from the image processing section, with a second transfer module, coincidentally with the the second segment being transferred to the image processing section.

摘要： A method of rotating an input image matrix of pixel data 180° to form an output image matrix of pixel data using a computer. The input image matrix is divided into pre-rotated bands of image pixels. Groups of pixels of a first pre-rotated band are accessed beginning at a bottom end of the first band and ending at a top end of the first band. The order of the pixels within each group of pixels of the first band is then reversed. The groups of reordered pixels are written to a band memory to form a rotated band of pixel data. In the rotated band of pixel data, the order of the groups of pixels of the rotated band is in reverse order to the order of the groups of pixels in the first band. The steps of accessing, reversing, and writing steps are repeated for the other bands of image pixels. Finally, the rotated bands are combined in reverse order of the pre-rotated bands to form the output image matrix. Optionally, the bands are concurrently reordered and compressed. By appropriately selecting the size of the groups of pixels and performing the steps on separate direct memory access masters, the method can take advantage of the bandwidth of high-performance busses to rotate and compress data in real-time.
