    摘要: A cache memory system for use in a motion estimation system is disclosed. The system includes: a first cache memory defined in terms of a first width and a first height, and a second cache memory defined in terms of a second width and a second height, wherein said second height is less than said first height, the cache memory system being operable in one of two modes: the first mode being characterised by banks of memory from the second cache memory being concatenated vertically such that their concatenated height is at least equal to the first height, and said concatenated banks being arranged to be appended to the width of the first cache memory to form a single contiguous address space; and the second mode being characterised by banks of memory from the first and second cache being stacked vertically, and being arranged to be addressed as two separate address spaces.

    摘要: A method of colour saturation compensation in a video signal is disclosed. The method includes the steps of: processing a luminance signal component of the video signal; determining whether the processing of the luminance signal results in a change in chrominance saturation; if the step of determining reveals that the chrominance saturation has changed, applying a chrominance compensation signal to the chrominance signals to counteract the effects of chrominance saturation, wherein said step of applying a compensation signal include the steps of: generating a compensation signal which is dependent on hue and luminance ratio (output luminance signal / input luminance signal). Apparatus for performing the method is also disclosed.

    摘要: A method includes receiving image information representing at least one image. The image information defines multiple pixels in the at least one image. The method also includes identifying filter weights associated with the pixels. The filter weights are based on edge contents of at least a portion of the at least one image. In addition, the method includes filtering the image information using the identified filter weights.
