Abstract
A motion detection section 720 detects a motion exceeding a permissible limit in a wide-viewing-angle image displayed on a head-mounted display 100. A field-of-view restriction processing section 750 restricts a field of view for observing the wide-viewing-angle image in a case in which the motion exceeding the permissible limit has been detected in the wide-viewing-angle image. An image provision section 760 provides, for the head-mounted display 100, the wide-viewing-angle image in which the field of view has been restricted.
Claims7
An image processing device comprising:
- a motion detection section configured to detect a motion exceeding a permissible limit in a wide-viewing-angle image displayed on a wearable display device;
- a field-of-view restriction processing section configured to restrict a field of view for observing the wide-viewing-angle image when the motion exceeding the permissible limit is detected in the wide-viewing-angle image;
- and
- an image provision section configured to provide the wide-viewing-angle image in which the field of view is restricted for the wearable display device,
- wherein the field-of-view restriction processing section restricts the field of view for observing the wide-viewing-angle image by using processing for masking a peripheral area of the wide-viewing-angle image,
- wherein transmittance of the masking is decreased from 100% to 0% over a predetermined time period,
- wherein, when receiving an operation instruction to zoom in or zoom out the wide-viewing-angle image beyond a predetermined scale factor, the motion detection section determines that the motion exceeding the permissible limit is detected and the field of view is restricted for a duration of the operation instruction, and
- wherein, when a motion that does not depend on a physical motion of a user is detected in the wide-viewing-angle image, the motion detection section determines that the motion exceeding the permissible limit is detected and the wide-viewing-angle image is masked.

An image processing method comprising:
- detecting a motion exceeding a permissible limit in a wide-viewing-angle image displayed on a wearable display device;
- restricting a field of view for observing the wide-viewing-angle image when receiving an operation instruction to zoom in or zoom out the wide-viewing-angle image beyond a predetermined scale factor for a duration of the operation instruction;
- and
- providing the wide-viewing-angle image in which the field of view is restricted for the wearable display device,
- wherein the masking includes making the peripheral area black and transparency of the masking is increased towards a center of the wide-viewing-angle image;
- and
- when receiving an operation instruction to zoom in or zoom out the wide-viewing-angle image beyond a predetermined scale factor from a fixed viewpoint, the motion detection section determines that the motion exceeding the permissible limit is detected and the field of view is restricted for a duration of the operation instruction, and
- when a motion that does not depend on a physical motion of a user is detected in the wide-viewing-angle image, it is determined that the motion exceeding the permissible limit is detected and the wide-viewing-angle image is masked.
