摘要： A source frame signal received at a first frame rate is converted to a destination frame signal output at a second frame rate. By adjusting the clock frequency of the clock signal in the destination frame signal, the second frame rate is made to be the same as the first frame rate. Adjusting the destination clock frequency prevents overflow and underflow conditions. The destination clock frequency is decreased to prevent underflow or increased to prevent overflow. The destination clock frequency during the last horizontal line is adjusted to comply with some display devices having a maximum time constraint from a last horizontal sync signal to a vertical sync signal in the destination frame signal.

摘要： A method and an apparatus for down-scaling an input image. The input image is composed of a series of image frames which are continuous in a time sequence. These image frames is grouped into at least a first set and a second set of image frames which are continuous and interchanging with each other. Sampling models employed in the present invention are typically following the method of skip-through. However, pixels contained in different sets of image frames are sampled by using different sampling models such that the lost of critical graphic information (e.g. pixel data) can be minimized after down-scaling. These sampled pixels of each image frame of each set are then output continuously by following the same order in the same time sequence. As a result, the complexity in both operation and architecture of the apparatus and the method of the present invention are reduced, and the problems of image blurring and losing partial image data which might otherwise happen in the prior arts are also solved.

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.

By adjusting the number of pixel data in the destination frame signal, the second frame rate is made to be the same as the first frame rate. Adjusting the amount of non-visible porch signals for at least one horizontal line of the destination frame signal prevents overflow and underflow conditions. The number of non-visible porch signals is increased to prevent underflow or decreased to prevent overflow.
