Image decoding apparatus, image decoding method, and storage medium

An image decoding method, the image decoding method comprising:

• acquiring information regarding a size of a region of interest that is a partial region in an image capable of being decoded;
• determining a frame rate for the region of interest in accordance with the information regarding the size of the region of interest acquired;
• and
• acquiring encoded data corresponding to the region of interest that is a partial region in the image and decode the encoded data corresponding to the region of interest, in accordance with the frame rate determined.

A non-transitory storage medium storing a program causing a computer to execute an image decoding process, the image decoding process comprising:

• acquiring information regarding a size of a region of interest that is a partial region in an image capable of being decoded;
• determining a frame rate for the region of interest in accordance with the information regarding the size of the region of interest acquired;
• and
• acquiring encoded data corresponding to the region of interest that is a partial region in the image and decode the encoded data corresponding to the region of interest, in accordance with the frame rate determined.

An image decoding apparatus comprising:

• a size acquisition unit configured to acquire information regarding a size of a region of interest that is a partial region in an image capable of being decoded;
• a determination unit configured to determine a frame rate for the region of interest in accordance with the information regarding the size of the region of interest acquired by the size acquisition unit;
• and
• a decoding unit configured to acquire encoded data corresponding to the region of interest that is a partial region in the image and decode the encoded data corresponding to the region of interest, in accordance with the frame rate determined by the determination unit.
