Information processing apparatus and control method therefor

An information processing apparatus comprising:

• a first obtaining unit configured to obtain information about at least one of a position and orientation of each of a plurality of image capturing apparatuses that capture an object from a plurality of different directions;
• a second obtaining unit configured to obtain information about at least one of a position and orientation of a virtual viewpoint;
• a reduction unit configured to reduce, based on information about at least one of the position and orientation of each of the plurality of image capturing apparatuses and at least one of the position and orientation of the virtual viewpoint, an information amount of a captured image selected from captured images of the plurality of image capturing apparatuses;
• and
• a control unit configured to control to store, in a memory, the captured image with the information amount reduced by the reduction unit.

A control method for an information processing apparatus that transmits, to an image processing apparatus for generating a virtual viewpoint image, at least some of a plurality of images based on image capturing from a plurality of different directions, the method comprising:

• obtaining an image based on image capturing by an image capturing apparatus;
• obtaining camera viewpoint information about at least one of a position and orientation of the image capturing apparatus;
• obtaining virtual viewpoint information about at least one of a position and orientation of the virtual viewpoint;
• reducing an information amount of the obtained image based on the camera viewpoint information and the virtual viewpoint information;
• and
• transmitting the image with the reduced information amount to the image processing apparatus.

A control method for an information processing apparatus, comprising:

• obtaining information about at least one of a position and orientation of each of a plurality of image capturing apparatuses that capture an object from a plurality of different directions;
• obtaining information about at least one of a position and orientation of a virtual viewpoint;
• reducing an information amount of a captured image selected from captured images of the plurality of image capturing apparatuses based on information about at least one of the position and orientation of each of the plurality of image capturing apparatuses and at least one of the position and orientation of the virtual viewpoint;
• and
• writing, in a storage device, the captured image with the reduced information amount.
