20190141341 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus divides a base image corresponding to a plurality of first images captured from different viewpoints, and a plurality of second images each corresponding to one or more of the plurality of first images, into a plurality of sub-bands including a sub-band that includes high-frequency components and a sub-band that does not include high-frequency components. As for the plurality of second images, the image processing apparatus then encodes the sub-band that includes high-frequency components. As for the base image, the image processing apparatus encodes the sub-band that does not include high-frequency components. | 2019-05-09 |
20190141342 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus divides a plurality of difference images that are based on addition and subtraction between a plurality of parallax images, and a composite image that is based on addition between a plurality of parallax images, into a plurality of sub-bands including a sub-band that includes high-frequency components and a sub-band that does not include high-frequency components. When encoding the plurality of difference images and the composite image, as for the plurality of difference images, the image processing apparatus encodes data of the sub-band that includes high-frequency components, and, as for the composite image, the image processing apparatus encodes data of the plurality of sub-bands. | 2019-05-09 |
20190141343 | IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD - An image processing apparatus divides a plurality of difference images that are based on addition and subtraction between a plurality of parallax images, and a second difference image between a current composite image that is based on addition of the plurality of parallax images and a past composite image, into a plurality of sub-bands. As for the plurality of first difference images, the image processing apparatus then encodes data of a sub-band that includes high-frequency components, out of the plurality of sub-bands. As for the second difference image, the image processing apparatus encodes data of the plurality of sub-bands. | 2019-05-09 |
20190141344 | VIDEO CODING METHOD, VIDEO DECODING METHOD, VIDEO CODING APPARATUS AND VIDEO DECODING APPARATUS - A moving picture coding method includes: making a determination as to whether or not to code all blocks in a current picture in the skip mode; setting, based on a result of the determination, a first flag indicating whether or not a temporally neighboring block is to be referenced, a value of a parameter for determining a total number of merging candidates, and a second flag for each block included in the current picture, the second flag indicating whether or not the block is to be coded in the skip mode; calculating, as a merging candidate, a neighboring block usable for merging; and coding an index which indicates a merging candidate to be used for coding of the current block and attaching the coded index to a bitstream. | 2019-05-09 |
