Abstract: In a first embodiment, a method of converting a source pixel data of a first format for a display of a second format having a plurality of three-color pixel elements comprises determining implied sample areas for each data point of each color in the source pixel data of the first format. The resample areas for each emitter of each color in the display is also determined. A set of fractions for each resample area is formed. The denominators are a function of the resample area and the numerators are the function of an area of each of the implied sample areas that at least partially overlaps the resample areas. The data values for each implied sample area is multiplied by its respective fraction and all products are added together to obtain luminance values for each resample area.

Abstract: A compact image element encoding format selectively allocates a bit field within the format to alternately encode either multi-bit alpha resolution or increased color resolution. This encoding technique may be advantageously used to allocate encoding bits to model semi-transparency while using those same bits for other purposes (e.g., higher color resolution) in instances where semi-transparency is not required (e.g., for opaque image elements). In one advantageous embodiment, the same encoding format can provide either RGB5 or RGB4A3, on an image-element-by-image-element basis. Applications include but are not limited to texture mapping in a 3D computer graphics system such as a home video game system or a personal computer.

Abstract: A system and method for converting color images divides a first image into first RGB values per pixel, determines which of the RGB colors in the first image has a greater specific gravity, converts the first RGB values into second RGB color values based on the color with the greater specific gravity, and forms a second image based on the second RGB values.

The first and second numbers of bits are different and preferably the first number is greater than the second number. Through this system and method, an M-bit color image may be converted into an N-bit color image with greater color accuracy than other methods which have been proposed.

The signal subjected to the aforesaid return operation is lastly reconverted from the YUV color space to the RGB color space, thus being susceptible to be displayed on the display.

Abstract: Graphics processing circuitry includes processing circuitry operative to generate pixel information in response to primitive information, and a correction circuit, coupled to the processing circuitry, operative to generate gamma corrected pixel information in response to the pixel information. The correction circuit converts the floating point pixel information generated by the processing circuitry into a gamma corrected fixed-point value so that gamma space pixel data is stored in the frame buffer. This fixed point gamma corrected pixel information, converted from the floating point pixel information, compensates for the non-linear display characteristics exhibited by current display devices. This results in the display output being more accurate; thereby, improving the appearance quality of the resulting image.

Abstract: Systems and methods for reducing bit rates by replacing original texture in a video sequence with synthesized texture. Reducing the bit rate of the video sequence begins by identifying and removing selected texture from frames in a video sequence. The removed texture is analyzed to generate texture parameters. New texture is synthesized using the texture parameters in combination with a set of constraints. Then, the newly synthesized texture is mapped back into the frames of the video sequence from which the original texture was removed. The resulting frames are then encoded. The bit rate of the video sequence with the synthesized texture is less than the bit rate of the video sequence with the original texture. Also, the ability of a decoder to decode the new video sequence is not compromised because no assumptions are made about the texture synthesis capabilities of the decoder.

Abstract: When highly redundant information that expresses five tones using 4 bits is transferred to a printer in terms of a unit data length in data transfer, efficiency is very poor. Hence, multi-valued data is quantized to 5-valued data, which is output as a 4-bit code that can express five values. 4-bit codes for three bits are combined to be converted into an 8-bit code. The 8-bit codes are packed into data of a 16-bit unit, and the packed data is transferred to the printer.

The alpha value for each pixel is then decremented by 1 (modulo 256) making the changed pixels opaque and the unchanged pixels transparent.

Then, the load of the pixel signal row is computed. The load is the number of pixel signal in the pixel signal row that the luminance value of the pixel signal is larger than a predetermined threshold luminance value.

Afterwards, each pixel signal in the pixel signal row is performed luminance compensation sequentially. If the luminance value is larger than or equal to a low threshold luminance value, the luminance value is subtracted by the primary luminance compensation value.

In one aspect, the encoding table is created when the second set of pixel byte values satisfy a threshold.

The dithering system combines frame rate control techniques with contributions from overlapping pixels to establish the intensity level of each sub-pixel. The dithering system initially provides an assignment of frame numbers to each sub-pixel. The dithering system then receives a logical pixel color that includes an intensity value for each component color (e.g., red, green, and blue) for each logical pixel. The dithering system maps each component intensity value of each logical pixel to an intensity value with a low depth plus a remainder. The dithering system generates a sub-pixel intensity value for each sub-pixel of each logical pixel using frame rate control to adjust the intensity value of each sub-pixel based on the remainder and current frame number.
