Abstract

This invention has an object to provide an image editing program and apparatus allowing users to intuitively produce images covering the omnidirection. In a virtual space, an omnidirectional image is projected according to a coordinate conversion and displayed at a display device 20. For omnidirectional image edition, a view direction and a view angle are changed in the virtual space with a pointing device 30, and under control of a central control unit 11, display of the omnidirectional image in a screen image is renewed to perform two-dimensional drawing to an image for drawing having the same coordinate system as that of the screen image with the pointing device 30 using the screen image as a clue. After the end of drawing, the coordinate conversion is made to the drawing image to project the image at a proper position of the omnidirectional image. The omnidirectional image is thus completed by repeating the steps of view direction changes and drawing.
