20130107944 | MOVING IMAGE ENCODING METHOD AND DECODING METHOD | 05-02-2013 |
20140010309 | IMAGE ENCODING METHOD AND IMAGE DECODING METHOD - According to one embodiment, disclosed is a method of dividing an input image signal into pixel blocks, and performing inter-prediction on the divided pixel blocks. This method includes selecting predicted motion information from a motion information buffer storing motion information in an encoded region, and predicting motion information of an encoding target block by using the predicted motion information. The method further includes acquiring representative motion information from a plurality of items of motion information in an encoded region in accordance with first information indicating a method of selecting the predicted motion information, thereby obtaining only the representative motion information. | 01-09-2014 |
20140185666 | APPARATUS AND METHOD FOR MOVING IMAGE ENCODING AND APPARATUS AND METHOD FOR MOVING IMAGE DECODING - According to certain embodiment, there is provided a moving image encoding apparatus in which a first encoding unit performs a first encoding process on an input image to generate first encoded data and to perform a first decoding process on the first encoded data to generate a first decoded image, a difference calculating unit generates a difference image between the input image and the first decoded image, a first pixel range converting unit converts pixel values of the difference image to be within a first specific range to generate a first converted image, a second encoding unit performs a second encoding process on the first converted image to generate second encoded data, the second encoding process being different from the first encoding process and the first specific range is a range including a range of pixel values that can be encoded by the second encoding unit. | 07-03-2014 |
20140205018 | IMAGE PROCESSING APPARATUS, IMAGE ENCODING APPARATUS, AND IMAGE PROCESSING METHOD - According to an embodiment, an image processing apparatus includes a first decoding unit, a selection unit and a generation unit. The first decoding unit generates a first decoded image by decoding first encoded data. The selection unit selects one of the first decoded image and the second decoded image for each display timing. The generation unit generates a display image to be displayed at a display timing for which the first decoded image is selected, based on the first decoded image. The second decoded image has a higher resolution than that of the first decoded image. The first decoded image and the second decoded image are different in either a frame rate or a display timing phase. | 07-24-2014 |
