摘要： A color conversion apparatus and a method of color conversion are described for converting a first color in a first color space to a second color in a second color space. The color conversion apparatus includes a plurality of lookup tables storing color mappings relating the first color space to the second color space and a converter using the lookup tables to convert the first color to the second color. The first color space is the sRGB color space and the second color space is a device dependent color space, or vice versa. To reduce the table size, tables having little effect on the second color contain groups of input colors mapping to a same output color and are implemented with a memory having the address inputs connected to the upper most significant bits of an incoming color value. A gamma correction circuit is used to calculate the remaining tables.

摘要： Data decoding devices avoiding data error from incorrect sampling points caused by serious interference are disclosed. The data decoding devices receive an analog signal carrying a reference clock and at least one digital data. In the data decoding device, a slicer slices the analog signal at different sampling points by first and second sampling clocks to obtain first and second bitstreams, and the first and second sampling clocks have the same frequency and a predetermined phase difference. A data check unit evaluates whether the first bitstream is erroneous according to an error checking code thereof, outputs the first bitstream if it is error-free, and evaluates whether the second bitstream is erroneous according to the error checking code if the first bitstream is erroneous.
