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. ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The image processing device according to claim 1, 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 or processing for blurring an entirety or periphery of the wide-viewing-angle image. ### Claim 3 (depends on 1) The image processing device according to claim 1, 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. ### Claim 4 (depends on 1) The image processing device according to claim 1, wherein when receiving an operation instruction to move in a virtual space displayed on the wearable display device beyond a predetermined speed, the motion detection section determines that the motion exceeding the permissible limit is detected. ### Claim 5 (depends on 1) The image processing device according to claim 1, 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. ### Claim 6 (depends on 1) The image processing device according to claim 1, wherein when a change amount in a point-of-view position or line-of-sight direction for observing the wide-viewing-angle image exceeds a predetermined threshold depending on a frame rate of the wide-viewing-angle image, the motion detection section determines that the motion exceeding the permissible limit is detected. ### Claim 7 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 the motion exceeding the permissible limit is detected in the wide-viewing-angle image; and providing the wide-viewing-angle image in which the field of view is restricted for the wearable display device. ### Claim 8 A program for a computer, comprising: by a motion detection section, detecting a motion exceeding a permissible limit in a wide-viewing-angle image displayed on a wearable display device; by a field-of-view restriction processing section, restricting 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 by an image provision section, providing the wide-viewing-angle image in which the field of view is restricted for the wearable display device.
