Abstract
A method of encapsulating an encoded bitstream representing one or more images includes providing description of images and/or sub-image picture, providing composed picture description, and outputting the bitstream. The description of images and/or sub-image pictures identifying portions of the bitstream representing the images and/or sub-images of the one or more images is provided. The composed picture description of at least one composed picture formed by one or more images and/or sub-image pictures also is provided. The bitstream, together with the composed picture description, is output as an encapsulated data file.
Claims25
A method for generating an image file based on a plurality of images, the method comprising:
- obtaining the plurality of images;
- and
- generating the image file based on the plurality of images,
- wherein the image file includes offset information for identifying a data position of each of the plurality of images within the image file, and includes composition image information relating to a composition image that is based on the plurality of images, and
- wherein the composition image information includes both of (i) horizontal offset information for representing a spatial position of each of the plurality of images in a horizontal direction within the composition image and (ii) vertical offset information for representing a spatial position of each of the plurality of images in a vertical direction within the composition image.
A method for reproducing image data in an image file, the method comprising:
- obtaining the image file including offset information for identifying a data position of each of a plurality of images within the image file and including composition image information relating to a composition image that is based on the plurality of images, wherein the composition image information includes both of (i) horizontal offset information for representing a spatial position of each of the plurality of images in a horizontal direction within the composition image and (ii) vertical offset information for representing a spatial position of each of the plurality of images in a vertical direction within the composition image;
- and
- reproducing the composition image by using the offset information, the horizontal offset information, and the vertical offset information.
An apparatus for generating an image file based on a plurality of images, the apparatus comprising:
- at least one processor;
- and
- at least one memory storing one or more programs configured to be executed by the at least one processor, the one or more programs including instructions for:
- obtaining the plurality of images, and
- generating the image file based on the plurality of images,
- wherein the image file includes offset information for identifying a data position of each of the plurality of images within the image file, and includes composition image information relating to a composition image that is based on the plurality of images, and
- wherein the composition image information includes both of (i) horizontal offset information for representing a spatial position of each of the plurality of images in a horizontal direction within the composition image and (ii) vertical offset information for representing a spatial position of each of the plurality of images in a vertical direction within the composition image.
An apparatus for reproducing image data in an image file, the apparatus comprising:
- at least one processor;
- and
- at least one memory storing one or more programs configured to be executed by the at least one processor, the one or more programs including instructions for:
- obtaining the image file including offset information for identifying a data position of each of a plurality of images within the image file and including composition image information relating to a composition image that is based on the plurality of images, wherein the composition image information includes both of (i) horizontal offset information for representing a spatial position of each of the plurality of images in a horizontal direction within the composition image and (ii) vertical offset information for representing a spatial position of each of the plurality of images in a vertical direction within the composition image, and
- reproducing the composition image by using the offset information, the horizontal offset information, and the vertical offset information.
A non-transitory computer-readable storage medium storing a program to cause a computer to execute a method for generating an image file based on a plurality of images, the method comprising:
- obtaining the plurality of images;
- and
- generating the image file based on the plurality of images,
- wherein the image file includes offset information for identifying a data position of each of the plurality of images within the image file, and includes composition image information relating to a composition image that is based on the plurality of images, and
- wherein the composition image information includes both of (i) horizontal offset information for representing a spatial position of each of the plurality of images in a horizontal direction within the composition image and (ii) vertical offset information for representing a spatial position of each of the plurality of images in a vertical direction within the composition image.
A non-transitory computer-readable storage medium storing a program to cause a computer to execute a method for reproducing image data in an image file, the method comprising:
- obtaining the image file including offset information for identifying a data position of each of a plurality of images within the image file and including composition image information relating to a composition image that is based on the plurality of images, wherein the composition image information includes both of (i) horizontal offset information for representing a spatial position of each of the plurality of images in a horizontal direction within the composition image and (ii) vertical offset information for representing a spatial position of each of the plurality of images in a vertical direction within the composition image;
- and
- reproducing the composition image by using the offset information, the horizontal offset information, and the vertical offset information.
