An image generating device includes: a storage section that stores images of surrounding spaces centered at plural different fixed points; a detecting section that detects translational movement on the basis of the location of the point of view; an image processor that acquires an image of a displaying target by clipping out part of the image of the surrounding space centered at the fixed point, stored in the storage section, on the basis of the location of the point of view and the direction of the line of sight; and a switching section that makes switching to the image of the surrounding space centered at another fixed point closest to the point of view after translational movement if the plural different fixed points are so disposed that the surrounding spaces centered at the fixed points overlap with each other in a world coordinate system and translational movement is detected.
