Abstract:
A data processing apparatus has a compression circuit and an output interface. The compression circuit has a pre-processor and a compressor. The pre-processor receives a first input display data in a first color domain, and performs a color format conversion upon the first input display data to generate a second input display data in a second color domain, wherein the second color domain is different from the first color domain. The compressor performs compression in the second color domain, wherein the compressor is arranged to compress the second input display data into a compressed display data in the second color domain. The output interface packs an output display data derived from the compressed display data into an output bitstream, and outputs the output bitstream via a display interface.

Abstract:
A data processing apparatus has a compressor and an output interface. The compressor generates a compressed display data by compressing a display data according to a compression algorithm. The output interface records indication information in an output bitstream, and outputs the output bitstream via a display interface, wherein the output bitstream is derived from the compressed display data, and the indication information is set in response to the compression algorithm employed by the compressor. Another data processing apparatus has a de-compressor and an input interface. The de-compressor de-compresses a compressed display data derived from an input bitstream. The input interface receives the input bitstream via a display interface, parses indication information included in the input bitstream, and configures the de-compressor to employ a de-compression algorithm as indicated by the indication information.

An image encoding method includes at least following steps: receiving a plurality of target pixels within a frame, wherein pixel data of each target pixel has at least one color channel data corresponding to at least one color channel; determining a bit budget of the target pixels; and performing bit-plane scanning coding upon selected pixels according to the bit budget and a scanning order, and accordingly generating encoded pixel data of the selected pixels as encoded data of the target pixels, wherein the selected pixels are derived from the target pixels, and the bit-plane scanning coding extracts partial bits of pixel data of each selected pixel as encoded pixel data of the selected pixel. In addition, a corresponding image decoding method is provided.
Abstract:
A decoding apparatus has an arithmetic decoder and a controller. A counter logic of the controller generates a first statistics result according to a first syntax element decoding result. A control logic of the controller instructs the arithmetic decoder to perform a first scan procedure at least once to generate the first syntax element decoding result of transform coefficients of a transform coefficient block, controls a repetition number of a second scan procedure based at least partly on the first statistics result, and instructs the arithmetic decoder to perform the second scan procedure at least once to generate a second syntax element decoding result of the transform coefficients. The first scan procedure decodes a first coded syntax element of one transform coefficient when performed by the arithmetic decoder once. The second scan procedure decodes a second coded syntax element of one transform coefficient when performed by the arithmetic decoder once.
Abstract:
A method for denoising images by block-matching three-dimensional (BM3D) method is disclosed in the present invention. Embodiments of the present invention are used to improve the quality of captured images. Instead of using the same noise variance to denoise all patches of an image, each patch is processed based on a particular assessed noise variance. The assessed noise variance of one reference patch is determined based on noise variance associated with the patch set or based on content characteristics associated with the patch set. The patch set is obtained by block-matching to find similar patches of the reference patch. Noise reduction in frequency domain is applied to the patch set according to the assessed noise variance of the reference patch. The determining of the assessed noise variance can be performed in spatial domain or in frequency domain.
