Image processing device, image processing method and image processing program for joining a plurality of divided images

An image processing device for joining at least first and second divided images produced from divided portions defined in a subject and having partially overlapping portions, comprising:

• a detecting portion for detecting a relative positional relationship between said first and second divided images having overlap regions overlapped together;
• a setting portion for setting a plurality of sets each including corresponding points in the two divided images within said overlapping regions based on the positional relationship detected by said detecting portion;
• and
• a joining portion for joining said two divided images based on said corresponding point sets.

An image processing method comprising the steps of:

• obtaining a plurality of divided images produced from divided portions defined in a subject and having partially overlapping portions;
• and
• producing an entire image representing said subject by joining said plurality of produced divided images, wherein
• the joining of said divided images is performed while placing higher importance on a specific portion among said overlapping regions.

An image processing method comprising the steps of:

• obtaining a plurality of divided images produced from divided portions defined in a subject and having partially overlapping portions;
• detecting a direction of positional shift between the two divided images having the overlap regions overlapping with each other;
• setting a plurality of sets each including corresponding points in said two divided images based on the detected positional shift direction;
• and
• joining said two divided images based on the set corresponding point sets.

An image processing program causing a computer to execute the steps of:
