20080310510 | Image Coding, Recording and Reading Apparatus - An image coding, recording and reading apparatus generates a local decoded image which is used for motion compensation prediction at the same time when coding an original image to be coded so as to generate an original image coded stream, acquires a difference image which is a difference between the local decoded image and the original image to be coded, codes the difference image so as to generate a difference image coded stream, records the original image coded stream and the difference image stream generated thereby into a storage memory, and adds an original image and a difference image which are obtained by decoding both the above-mentioned coded streams read out of the storage memory, respectively, so as to generate an addition image. | 12-18-2008 |

20150043630 | IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE, IMAGE ENCODING METHOD, AND IMAGE DECODING METHOD - An image decoding device and an image decoding method are disclosed. The decoding device includes: a variable length decoder to variable-length-decode an inputted encoded bit stream to obtain a parameter for prediction signal generation, a compressed difference image, and filters; and a filtering processor to carry out a filtering process on a decoded image acquired by adding a prediction image and a difference image, wherein the prediction image is generated by using the parameter for prediction signal generation, and the difference image is acquired by decoding the compressed difference image, wherein the variable length decoder variable-length-decodes class identification information for a block in the decoded image, and wherein the filtering processor refers to the class identification information for the block to determine a class for the block, and carries out a filtering process on the block based on the determined class and the filters. | 02-12-2015 |
20150195582 | VIDEO ENCODING DEVICE, VIDEO DECODING DEVICE, VIDEO ENCODING METHOD, AND VIDEO DECODING METHOD - Since time hierarchically encoded video data needs to include video data of a basic hierarchical layer, and video data cannot be generated in which a frame belonging to an upper hierarchical layer is only encoded, even in a case in which only a part of frames is processed, a basic hierarchical layer frame is needed to be included, and thus, there has been a problem that video data in which only the frame belonging to the upper hierarchical layer is encoded cannot be separately processed. In the present invention, a variable length encoding unit is disposed which encodes, for each sequence, a basic hierarchical layer existence flag showing whether or not a basic hierarchical layer is included in the sequence. | 07-09-2015 |
