Image processing apparatus and image processing method

An image processing method executed by an image processing apparatus, comprising:

• an acceptance step of accepting, of a plurality of images generated by projecting an omnidirectional image mapped to a 3D model onto a plurality of two-dimensional planes, an image corresponding to a viewing direction of a user and the omnidirectional image reduced in resolution;
• a drawing step of generating a display image on a basis of at least one of the image or the omnidirectional image reduced in resolution accepted by the process in the acceptance step;
• a viewing direction acquisition step of acquiring viewing direction information related with the viewing direction of the user;
• and
• a sending step of sending a viewing direction log recorded on a basis of the viewing direction information acquired by the process in the viewing direction acquisition step.

An image processing apparatus comprising:

• a storage block configured to store a plurality of images generated by projecting an omnidirectional image mapped to a 3D model onto a plurality of two-dimensional planes and the omnidirectional image reduced in resolution;
• a sending block configured to send the omnidirectional image and an image corresponding to a viewing direction of a user among the plurality of images to a terminal;
• an acceptance block configured to accept a viewing direction log related with the viewing direction of the user from the terminal;
• and
• an image change block configured to change the plurality of images stored in the storage block in accordance with the viewing direction log accepted by the acceptance block.

An image processing method executed by an image processing apparatus, comprising:

• a sending step of sending, from a storage block in which a plurality of images generated by projecting an omnidirectional image mapped to a 3D model onto a plurality of two-dimensional planes and the omnidirectional image reduced in resolution are stored, the omnidirectional image and an image corresponding to a viewing direction of a user among the plurality of images to a terminal;
• an acceptance step of accepting a viewing direction log related with the viewing direction of the user from the terminal;
• and
• an image changing step of changing the plurality of images stored in the storage block in accordance with the viewing direction log accepted by the process in the acceptance step.
