Abstract:
1. An image generating apparatus comprising: an input unit inputting an instruction about a shift of a range of an image to be displayed on a screen; a determination unit for determining, when said range is successively shifted, a predetermined parameter value related to an image to be displayed based on an altitude of virtual point of view according to a movement speed in a coordinate system in an instructed direction; an obtaining unit for identifying a plurality of original images with respective parameters defined based on the parameter value determined by the determination unit, and for obtaining the plurality of original images identified; and an image generating unit for performing a predetermined converting process upon the plurality of original images so that the parameter values of the plurality of original images match the parameter value determined by the determination unit, and for outputting a final image obtained by combining the plurality of original images so that their corresponding areas are made to overlap, wherein: when the movement speed in the coordinate system in the instructed direction changes, the determination unit updates the parameter value so that an on-screen movement speed of an image currently displayed on the screen is maintained; and the image generating unit performs a processing so that the parameter value of the final image matches the parameter value updated in the determination unit.
