1. An image generating method comprising:
- a first step of generating a small region panorama image group which is an image group of N images which include a shooting range common to each other, the N images being composed of a plurality of common partially overlapped regions and having independency from each other in each of the partially overlapped regions, wherein N is an integer larger than 2; and
a second step of generating, for a target image obtained by shooting at least a part of the shooting range, a predicted background image in which light source environment is the same as that of the target image with the use of the target image and the small region panorama image group.

Abstract
A small region panorama image group (I1P, I2P, I3P) is generated in advance. The small region panorama image group (I1P, I2P, I3P) includes images including a common shooting range, being composed of a plurality of common partially overlapped regions (A, B, C, D), and having independency from each other in each partially overlapped region (A, B, C, D). With the use of the small region panorama image group (I1P, I2P, I3P), a predicted background image is generated in which light source environment is the same as that of a shot target image.

5. Object detecting equipment comprising:
-
a small region panorama image group generation section for generating, with the use of a plurality of images stored in a shot image storing section, a small region panorama image group which is an image group of N images which include a shooting range common to each other, the N images being composed of a plurality of common partially overlapped regions and having independency from each other in each of the partially overlapped regions, wherein N is an integer larger than 2; and
an object detection section for detecting an object reflected in a detection target image obtained by shooting at least a part of the shooting range by generating a predicted background image in which light source environment is the same as that of the detection target image is generated for the detection target image with the use of the detection target image and the small region panorama image group and comparing the detection target image and the predicted background image with each other.

6. An image generating program for allowing a computer to execute image generation, wherein the computer executes:
-
a first step of generating a small region panorama image group which is an image group of N images which include a shooting range common to each other, the N images being composed of a plurality of common partially overlapped regions and having independency from each other in each of the partially overlapped regions, wherein N is an integer larger than 2; and
a second step of generating, for a target image obtained by shooting at least a part of the shooting range, a predicted background image in which light source environment is the same as that of the target image with the use of the target image and the small region panorama image group.
