Abstract
The present disclosure relates to an image processing device and an image processing method for instantaneously displaying an image of a user's field of view. An encoder encodes a celestial sphere image of a cube formed by images of multiple planes generated from omnidirectional images, the encoding being performed plane by plane at a high resolution, to generate a high-resolution encoded stream corresponding to each of the planes. The encoder further encodes, at a low resolution, the celestial sphere image to generate a low-resolution encoded stream. The present disclosure may be applied, for example, to image display systems that generate a celestial sphere image so as to display an image of the user's field of view derived therefrom.
Claims20
An image processing device comprising:
- a first encoding section configured to encode a first celestial sphere image of a model formed by images of a plurality of planes generated from omnidirectional images, the encoding being performed plane by plane at a first resolution, to generate a first encoded stream corresponding to each of the planes;
- and
- a second encoding section configured to encode, at a second resolution, a second celestial sphere image generated from the omnidirectional images to generate a second encoded stream.
An image processing method comprising:
- a first encoding step by an image processing device of encoding a first celestial sphere image of a model formed by images of a plurality of planes generated from omnidirectional images, the encoding being performed plane by plane at a first resolution, to generate a first encoded stream corresponding to each of the planes;
- and
- a second encoding step by the image processing device of encoding, at a second resolution, a second celestial sphere image generated from the omnidirectional images to generate a second encoded stream.
An image processing device comprising:
- a decoding section configured to decode, with respect to a first encoded stream generated by dividing a first celestial sphere image of a model formed by images of a plurality of planes generated from omnidirectional images into the planes and encoding the image plane by plane at a first resolution and a second encoded stream generated by encoding a second celestial sphere image generated from the omnidirectional images at a second resolution, the first encoded stream corresponding to one of each opposed pair of the planes to generate the first celestial sphere image of the corresponding plane at the first resolution.
An image processing method comprising:
- a decoding step by an image processing device of decoding, with respect to a first encoded stream generated by dividing a first celestial sphere image of a model formed by images of a plurality of planes generated from omnidirectional images into the planes and encoding the image plane by plane at a first resolution and a second encoded stream generated by encoding a second celestial sphere image generated from the omnidirectional images at a second resolution, the first encoded stream corresponding to one of each opposed pair of the planes to generate the first celestial sphere image of the corresponding plane at the first resolution.
