    Abstract: The technique disclosed herein makes it possible to save a proper screenshot, i.e., images with display angles of view of an HMD, and also enable one to check a situation even outside the display angles of view at the time of saving the screenshot. When receiving a notification that a screen capture command is received from a command receiver, an image file generator acquires wide angle images from a wide angle image generator, acquires display angle-of-view information from a display image generator, sets the wide angle images as image data to be stored in a main image region of an image file, sets the acquired display angle-of-view information as data to be stored in a metadata region of the image file, generates an image file of a screenshot according to the settings, and saves the image file in an HDD.
