Image processing device and image processing method

An image processing method comprising:

• setting first temporal resolution for a first partial region higher than second temporal resolution for a second partial region, wherein
• the first partial region corresponds to one of a center image and a front image of image data,
• the second partial region corresponds to at least one image of the image data different from the center image and the front image, and
• the first partial region and the second partial region are included in one frame of the image data;
• and
• coding the image data to generate a bit stream including information indicating the first temporal resolution and the second temporal resolution.

An image processing device comprising:

• a reception unit configured to receive a bit stream in which image data is coded;
• an analysis unit configured to analyze information included in the received bit stream and indicating first temporal resolution and second temporal resolution for a first partial region and a second partial region of image data respectively, wherein
• the first partial region corresponds to one of a center image and a front image of the image data,
• the second partial region corresponds to at least one image of the image data different from the center image and the front image, and
• the first partial region and the second partial region are included in one frame of the image data;
• a data extraction unit configured to extract data of the first partial region and the second partial region from the received bit stream in accordance with the first temporal resolution and the second temporal resolution;
• and
• a bit stream generation unit configured to convert the received bit stream based on the extracted data, wherein
• the converted bit stream is different from the received bit stream, and
• the reception unit, the analysis unit, the data extraction unit, and the bit stream generation unit are each implemented via at least one processor.

An image processing device comprising:

• the information is included in a bit stream in which the image data is coded, and
• the first temporal resolution is higher than the second temporal resolution;
• and
• a decoding unit configured to partially decode, as a current frame of the image data, the coded image data corresponding to the first partial region in accordance with the analyzed information while complementing the second partial region based on a frame of the image data different from the current frame,
• wherein the analysis unit and the decoding unit are each implemented via at least one processor.
