Abstract
Provided is an image processing device including: a division unit that divides pictures of image data into multiple arrangements; multiple coding units, each of which codes pictures in the mutually-different arrangements that result from the division by the division unit and generates a stream; and a composition unit that composites the streams in the arrangements, which are generated by the multiple coding units, in which the coding unit generates header information on the stream in such a manner that a stream which results from the compositing by the composition unit becomes normal.
Claims15
An image processing device comprising:
- coding circuitry configured to:
- divide pictures of image data into a first group of even-numbered images and a second group of odd-numbered images;
- parallel process the first group and the second group independently of each other to generate a first stream of coded data of the first group and a second stream of coded data of the second group, wherein no information is exchanged between processing of the first group and the second group, a front picture of a group-of-pictures (GOP) structure of the first stream is coded as an 1-frame and a front picture of the GOP structure of the second stream is coded as a P-frame;
- and
- composite the first steam and the second stream by alternatively arranging each one of the first group and the second group, wherein (i) a first header information of the first stream and (ii) a second header information of the second stream are combined to generate header information on the composited first and second streams.
An image processing method performed by coding circuitry, the method comprising:
- dividing pictures of image data into a first group of even-numbered images and a second group of odd-numbered images;
- parallel processing the first group and the second group independently of each other to generate a first stream of coded data of the first group and a second stream of coded data of the second group, wherein no information is exchanged between processing of the first group and the second group, a front picture of a group-of-pictures (GOP) structure of the first stream is coded as an I-frame and a front picture of the GOP structure of the second stream is coded as a P-frame;
- and
- compositing the first steam and the second stream by alternatively arranging each one of the first group and the second group, wherein (i) a first header information of the first stream and (ii) a second header information of the second stream are combined to generate header information on the composited first and second streams.
A non-transitory computer readable medium storing a program thereon that, when executed by coding circuitry, causes the coding circuitry to perform a method comprising:
- dividing pictures of image data into a first group of even-numbered images and a second group of odd-numbered images;
- parallel processing the first group and the second group independently of each other to generate a first stream of coded data of the first group and a second stream of coded data of the second group, wherein no information is exchanged between processing of the first group and the second group, a front picture of a group-of-pictures (GOP) structure of the first stream is coded as an I-frame and a front picture of the GOP structure of the second stream is coded as a P-frame;
- and
- compositing the first steam and the second stream by alternatively arranging each one of the first group and the second group, wherein (i) a first header information of the first stream and (ii) a second header information of a second stream are combined to generate header information on the composited first and second streams.
An image processing apparatus comprising:
- coding circuitry configured to:
- image a photographic subject;
- divide pictures of image data that the coding circuitry obtains by imaging the photographic subject into a first group of even-numbered images and a second group of odd-numbered images;
- parallel process the first group and the second group independently of each other to generate a first stream of coded data of the first group and a second stream of coded data of the second group, wherein no information is exchanged between processing of the first group and the second group, a front picture of a group-of-pictures (GOP) structure of the first stream is coded as an I-frame and a front picture of the GOP structure of the second stream is coded as a P-frame;
- and
- composite the first steam and the second stream by alternatively arranging each one of the first group and the second group, wherein (i) a first header information of the first stream and (ii) a second header information of the second stream are combined to generate header information on the composited first and second streams.
