Abstract
There is provided an image coding apparatus including: circuitry configured to set a correspondence relationship between resolution information and an enhancement layer, in a case where the number of the layers is greater than the number of multiple candidates for the resolution information on a layer of an image; and code the image and generate a bitstream including information relating to the set correspondence relationship.
Claims14
An image encoding apparatus comprising:
- circuitry configured to:
- set a number of resolution information on a layer of an image which is transmitted previously;
- set, in a case where the set number of the resolution information is greater than 1, information indicating whether or not a correspondence relationship between the resolution information and an enhancement layer of the image is present, the information being transmitted after the number of the resolution information;
- not transmit, in a case where the set number of the resolution information is 1, the information indicating whether or not the correspondence relationship between the resolution information and the enhancement layer is present;
- and
- encode the image and generate a bitstream including the number of resolution information and the information relating to the correspondence relationship.

An image encoding method comprising:
- setting a number of resolution information on a layer of an image which is transmitted previously;
- setting, in a case where the set number of the resolution information is greater than 1, information, indicating whether or not a correspondence relationship between the resolution information and an enhancement layer is present, the information being transmitted after the number of the resolution information;
- not transmitting, in a case where the set number of the resolution information is 1, the information indicating whether or not the correspondence relationship between the resolution information and the enhancement layer is present;
- and
- encoding the image and generating a bitstream including the number of resolution information and the information relating to the correspondence relationship.

A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute an image encoding method, the method comprising:
- setting a number of resolution information on a layer of an image which is transmitted previously;
- setting, in a case where the set number of the resolution information is greater than 1, information indicating whether or not a correspondence relationship between the resolution information and an enhancement layer is present, the information being transmitted after the number of the resolution information;
- not transmitting, in a case where the set number of the resolution information is 1, the information indicating whether or not the correspondence relationship between the resolution information and the enhancement layer is present;
- and
- encoding the image and generating a bitstream including the number of resolution information and the information relating to the correspondence relationship.

An image encoding apparatus comprising:
- a setting unit configured to
- set a number of resolution information on a layer of an image which is transmitted previously,
- set, in a case where the set number of the resolution information is greater than 1, information indicating whether or not a correspondence relationship between the resolution information and an enhancement layer is present, the information being transmitted after the number of the resolution information, and
- not transmit, in a case where the set number of the resolution information is 1, the information indicating whether or not the correspondence relationship between the resolution information and the enhancement layer is present;
- and
- an encoding unit configured to encode the image and generate a bitstream including the number of resolution information and the information relating to the correspondence relationship, wherein the setting unit and the encoding unit are each implemented via at least one processor.
