Image processing device, image processing method, and image processing program

An image processing method, comprising:

• a control step of controlling a scan frequency of a region of an imaging unit;
• and
• an analysis step of analyzing a captured image captured in the imaging unit,
• wherein the analysis step includes steps of
• analyzing the captured image to detect an optical signal transmitted from a signal source,
• identifying an attribute of the signal source on the basis of information included in the detected optical signal, and
• setting a region including the signal source in the captured image in a region with a different scan frequency, and
• the control step includes a step of controlling a scan frequency of the imaging unit for each region that is set in the captured image.

An image processing program that causes a computer to execute:

• a control procedure of controlling a scan frequency of a region of an imaging unit;
• and
• an analysis procedure of analyzing a captured image captured in the imaging unit,
• wherein the analysis procedure includes procedures of
• analyzing the captured image to detect an optical signal transmitted from a signal source,
• identifying an attribute of the signal source on the basis of information included in the detected optical signal, and
• setting a region including the signal source in the captured image in a region with a different scan frequency, and
• the control procedure includes a procedure of controlling a scan frequency of the imaging unit for each region that is set in the captured image.
