Field: Computer technology (Electrical engineering)
Classification: CPC G  B | IPC B  G

Claim 0:
1. A non-transitory computer readable storage medium storing computer readable instructions that are executable by a computer, the computer readable instructions, when executed by the computer, causing the computer to:
obtain first image data composing a first image and second image data composing a second image, the second image corresponding to an object;
specify a plurality of first edge pixels in the first image with use of the first image data and a plurality of second edge pixels in the second image with use of the second image data;
determine positional relation between the first image and the second image in a first degree of accuracy;
based on positional relation between the plurality of first edge pixels and the plurality of second edge pixels within the determined positional relation between the first image and the second image, determine a plurality of first usable pixels among the plurality of first edge pixels and a plurality of second usable pixels among the plurality of second edge pixels, a sum of the plurality of first usable pixels and the plurality of second usable pixels being smaller than a sum of the plurality of first edge pixels and the plurality of second edge pixels; and
with use of the plurality of first usable pixels and the plurality of second usable pixels, determine positional relation between the first image and the second image in a second degree of accuracy, the second degree being higher than the first degree.
