Abstract
A low dynamic range (LDR) image data storage stores LDR image sets each of which includes a plurality of LDR segmented images captured with a camera panned. Here each LDR image set is of a different exposure level, respectively. A high-dynamic-range (HDR) synthesizing unit combines and merges a plurality of LDR segmented images of different exposure levels so as to generate an HDR segmented image set including a plurality of HDR segmented images of different pan angles or tilt angles. A panoramic image synthesizing unit generates an HDR panoramic image by stitching together adjacent HDR segmented images.
