IMAGE GENERATION APPARATUS AND IMAGE GENERATION METHOD

A panorama image processing unit generates a wide viewing angle image like a panorama image which is seen from a given point of view. An image conversion unit converts the generated wide viewing angle image into an image of a transmission format in which the angular resolution which is a number of pixels per unit angle centered at the point of view is adjusted in response to a ray direction toward the point of view. An image provision unit transmits the image in the transmission format in which the angular resolution is adjusted to a head-mounted display unit. The head-mounted display unit converts the received image so as to conform the image to an optical characteristic of a device and displays the image on the device.
