    摘要: A line-based one-dimensional system and method for video and graphic compression compresses an image data block that contains image data values from one or more neighboring pixels. The system and method involves compressing an image data sample of the image data block using multiple different compression techniques to generate multiple compression results, selecting one of the compression results, and compressing a next image data sample using the multiple different compression techniques and a compression error from the selected one of the compression results.

    摘要: A display device (506) is driven in a number of sub-fields. Each of the sub-fields is for outputting a respective illumination level by the display device. In each sub-field, a pixel of the displayed image may emit an amount of light corresponding to the particular sub-field, depending on whether it is switched on or not. A required intensity level of the pixel is realized by selecting an appropriate combination of sub-fields in which the pixel is switched on. A selection is made from the possible intensity levels that can be generated by all possible combinations of sub-fields. The selected intensity levels are uniformly spaced on a perceptual scale, allowing a relatively small number of intensity levels for displaying an image with a relatively high perceived quality. The image display unit (300) has a the combinations of sub-fields for the respective selected intensity levels.

A selection is made from the possible intensity levels that can be generated by all possible combinations of sub-fields. This selection contains those intensity levels that can be generated by sub-fields that are temporally close together, thus causing that the light of a pixel is emitted during a relatively short period. The image display unit (300) has a look-up table (306) for storing the combinations of sub-fields for the respective selected intensity levels.

    摘要: An image rendering system renders a color image in which each pixel is associated with a respective aim color value. A quantizer selecta a respective quantized value indicating a color from a palette of colors for each pixel, in dependence on the aim color value associated with that pixel. The pixels are rendered with the colors indicated by the respective quantized values. The palette consists of a proper subset of the set of all colors that the aim color values can represent, and contains at least one palette color which does not lie on an RGB boundary, and is perceptually closer than any other of the palette color values to an RGB boundary color belonging to said set. For pixels for which the aim color value represents said RGB boundary color the quantizer means selects a quantized value indicating a further palette color, that lies on the RGB boundary.

    摘要: An index determination element selects index values as a function of the source color values. The index values pointing to LUT color values stored in a lookup table unit. The LUT color values read from the lookup table unit are used to generate output color values. Each output color value corresponds to a pixel, a first component of the output color values is output for at least two pixels at a time and second components are output separately for each of these at least two pixels. As a result there is a space of combinations of index values that results in substantially the same first component of the output values, even though they points to substantially different LUT color values for these at least two pixels. The index determination element selects a combination from this space to minimize an error in the second components of the output color values for the at least two pixels.

    摘要: A testable processor system (10,20) comprises a plurality of modules (11, 12, . . . In). Each module (11) comprises a processor unit (110) and a debug controller (111). The debug controllers are coupled to a common test access point controller (TAP-controller 20), and have a test data input (Tin), a test data output (Tout) and at least one test register (112, 113). The test data inputs and outputs of the debug controllers (111, 121, 131, . . . , InI) are arranged in a scan chain having an input for receiving test input data (TDI) from the TAP-controller and an output for providing test output data (TDO) to the TAP-controller. At least one debug controller (111) has a selection facility (115) to select whether data in the scanchain is either shifted through the at least one test register (112) of that debug controller (111) or is immediately forwarded from the test data input (Tin) to the test data output (Tout) of that debug controller. The at least one debug controller has a bypass register (117) which controls the selection facility. The TAP-controller (20) provides a control signal (BYPASS CNTRL) which, when active, selects the bypass register as part of the scan chain.

    摘要: In a method of mixing a graphics signal and a video signal in a ratio alpha:(1-alpha), where the graphics signal is obtained by addressing a color look-up table (CLUT) in which color values (R, G, B) are stored, the number of color values stored for each mixing ratio depends on the mixing ratio so as to obtain an optimum filling of the color look-up table.
