IMAGE GENERATION DEVICE, AUTOMATIC GENERATION METHOD, RECORDING MEDIUM, AND PROGRAM

摘要

A parts selection unit (203) reads out outline information stored in an outline information storage unit (212) and selects a parts image in alignment with stored outline information. Then the parts selection unit (203) selects remaining parts so that the total work load is within a range not exceeding a predetermined allowable value, based on stored indicator information. That is, with the processing loads of successively selected parts image being calculated in the processing load calculation unit (204), a remaining parts image is selected. Image rendering unit (206) generates a three-dimensional image based on each parts image selected by the parts selection unit (203) and stored in a map storage unit (205).
