Abstract
An encoding device includes a memory, and a processor coupled to the memory and the processor configured to extract a first line-drawing region from a first image in a plurality of images, by replacing the first line-drawing region of the first image with an image which is included in a second image preceding the first image in the plurality of images and corresponds to the first line-drawing region, generate a third image, generate video encoding information by performing a video encoding processing based on the third image, generate line-drawing encoding information by performing a line-drawing encoding processing based on the first line-drawing region, and transmit the video encoding information and the line-drawing encoding information to a decoding device.
Claims6
An encoding device comprising:
- a memory;
- and
- a processor coupled to the memory and the processor configured to:
- extract a first line-drawing region which indicates a line drawing, from a first image in a plurality of images,
- by replacing the first line-drawing region of the first image with an image which is included in a second image preceding the first image in the plurality of images and corresponds to the first line-drawing region, generate a third image,
- generate video encoding information by performing a video encoding processing based on the third image,
- generate line-drawing encoding information which indicates encoding information of the first line-drawing region, by performing a line-drawing encoding processing based on the first line-drawing region,
- transmit the video encoding information and the line-drawing encoding information to a decoding device,
- determine whether a second line-drawing region is included in a fourth image following the first image in the plurality of images, the video encoding processing being performed based on the fourth image when the second line-drawing region is not included in the fourth image,
- store, by overwriting, the third image on the second image stored in a buffer, and
- generate a fifth image by replacing the second line-drawing region of the fourth image with an image which is included in the third image stored in the buffer and corresponds to the second line-drawing region when the second line-drawing region is included in the fourth image, and
- the video encoding processing is performed based on the fifth image when the second line-drawing region is included in the fourth image.
An encoding method comprising:
- extracting a first line-drawing region which indicates a line drawing, from a first image in a plurality of images;
- by replacing the first line-drawing region of the first image with an image which is included in a second image preceding the first image in the plurality of images and corresponds to the first line-drawing region, generating a third image;
- generating video encoding information by performing a video encoding processing based on the third image;
- generating line-drawing encoding information which indicates encoding information of the first line-drawing region, by performing a line-drawing encoding processing based on the first line-drawing region;
- transmitting the video encoding information and the line-drawing encoding information to a decoding device;
- determining whether a second line-drawing region is included in a fourth image following the first image in the plurality of images, the video encoding processing being performed based on the fourth image when the second line-drawing region is not included in the fourth image;
- storing, by overwriting, the third image on the second image stored in a buffer;
- and
- generating a fifth image by replacing the second line-drawing region of the fourth image with an image which is included in the third image stored in the buffer and corresponds to the second line-drawing region when the second line-drawing region is included in the fourth image,
- the video encoding processing is performed based on the fifth image when the second line-drawing region is included in the fourth image.
