Abstract: A technique that improves image analysis efficiency by reducing the number of computations needed to detect constant regions. Constant region detection according to the present techniques includes determining whether an image analysis window at a current position contains a constant region by analyzing a new line of pixels in the image analysis window if a pixel at a predetermined location in the image analysis window in the current position has a value equal to a pixel at the predetermined location from a previous position of the image analysis window. Analyzing only the new line of pixels saves the computational time that would otherwise go into analyzing all of the pixels in the image analysis window.

Abstract: A system and method for modifying a print job based on an analysis of the media to which the print job is to be printed. In one embodiment, a printer includes a controller operable to receive a signal representing a print job such that the controller is operable to interpret the signal into command signals for printing the print job to media. The printer further includes a media analysis device operable to analyze a characteristic of the media to which the print job is printed. The printer further includes a print job modification component that is coupled to the controller and to the media analysis device such that the print job adjustment component is operable to modify the print job in response to the analysis of the media.

Abstract: A host-based color printing system having a color printing accelerator module that assists the host processor in order to speed up the rate at which color formatting tasks are performed by the host. The color printing accelerator module has an I/O interface that connects to a first I/O port of the host computer of the host-based color printing system. A second I/O port of the host computer connects to an I/O interface of the printer. After the color formatting tasks have been performed by the host computer and the color printing accelerator module, the processed data is sent from the host computer to the printer for printing.

Abstract: Image data is converted from a first color space to a second color space. An image acquisition device acquires first color space image data of a pixel of an image. It is then determined if the first color space image data of the pixel and second color space image data of the pixel are referenced in a data structure. The second color space image data of the pixel is selected for sending to an output device if the first color space image data and the second color space image data of the pixel are referenced in the data structure. If the first color space image data and the second color space image data of the pixel are not referenced in the data structure, then the first color space image data of the pixel is transformed into the second color space image data of the pixel. The data structure can be a hash table. Also, the first color space can be RGB and the second color space can be CYMK.
