20120301030 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND RECORDING MEDIUM - An image processing apparatus includes: an input portion | 11-29-2012 |
20140105288 | IMAGE ENCODING DEVICE, IMAGE ENCODING METHOD, IMAGE DECODING DEVICE, IMAGE DECODING METHOD, PROGRAM, AND STORAGE MEDIUM - A prediction set determining section selects a prediction set from a prediction set group including a plurality of prediction sets having different combinations of prediction modes corresponding to different prediction directions. Further, a prediction mode determining section selects a prediction mode from the prediction set thus selected. An entropy encoding section encodes the prediction set thus selected, the prediction mode thus selected, and residual data between an input image and a predicted image formed on the basis of the prediction set and the prediction mode. This allows an image encoding device to carry out predictions from more various angles, thereby improving prediction efficiency. | 04-17-2014 |
20140307801 | ARITHMETIC DECODING DEVICE, IMAGE DECODING DEVICE, ARITHMETIC CODING DEVICE, IMAGE CODING DEVICE, AND ARITHMETIC DECODING METHOD - The amount of processing is reduced with high coding efficiency maintained. There is provided an arithmetic decoding device including syntax decoding means for decoding each of at least a first syntax element and a second syntax element indicating a transform coefficient using arithmetic decoding with a context or arithmetic decoding without a context. The syntax decoding means performs decoding that at least includes not decoding the first syntax element and decoding the second syntax element using the arithmetic decoding without a context, and decoding the first syntax element using the arithmetic decoding with a context and decoding the second syntax element using the arithmetic decoding without a context. | 10-16-2014 |
20140348247 | ARITHMETIC DECODING DEVICE, IMAGE DECODING DEVICE, AND ARITHMETIC CODING DEVICE - To reduce the amount of processing related to coding and decoding of transform coefficients, a sub-block coefficient presence/absence flag indicating whether or not at least one non-zero transform coefficient is included is decoded for each of two or more sub-blocks obtained by dividing a unit region, and a context index of a target sub-block is derived on the basis of transform coefficient presence/absence flags each indicating whether or not a transform coefficient is 0. In accordance with the sub-block coefficient presence/absence flags of adjacent sub-blocks that are adjacent to the target sub-block, the context index of the target sub-block is derived. | 11-27-2014 |
20150110199 | ARITHMETIC DECODING DEVICE, IMAGE DECODING APPARATUS, ARITHMETIC CODING DEVICE, AND IMAGE CODING APPARATUS - In order to simplify hardware and improve coding efficiency, an adjacent sub-block coefficient presence/absence context deriving unit | 04-23-2015 |
20150181237 | ARITHMETIC DECODING DEVICE, ARITHMETIC CODING DEVICE, IMAGE DECODING APPARATUS, AND IMAGE CODING APPARATUS - A coefficient presence/absence flag decoding unit ( | 06-25-2015 |
20150222914 | IMAGE DECODING DEVICE AND IMAGE CODING DEVICE - A reference picture information decoding unit ( | 08-06-2015 |
20150245046 | IMAGE DECODING DEVICE - An image decoding device is equipped with a header information decoding means for decoding profile/level information included in a video parameter set after decoding byte-aligned 16-bit extension information (next_essential_info_byte_offset) in the video parameter set. | 08-27-2015 |
