Target detection device, machine learning implementation device, target detection program, and machine learning implementation program

A non-transitory computer-readable storage medium storing a target detection program causing a computer to perform:

• a first image acquiring function to acquire a first image depicting the subject, which is generated by irradiating a subject with light belonging to a first wavelength group;
• a second image acquiring function to acquire a second image depicting the subject, which is generated by irradiating the subject with light belonging to a second wavelength group other than the first wavelength group and having a different wavelength from the light with which the subject has been irradiated to generate the first image;
• and
• a target detecting function to detect a target included in the subject using the first image and the second image,
• wherein, at least one of the first image acquiring function or the second image acquiring function is configured to acquire an image in which each pixel represents a value calculated based on a luminance of a main image and a luminance of a subordinate image,
• the luminance of the main image obtained as a result of irradiating the subject with light belonging to the first wavelength group or the second wavelength group, the main image being obtained based on a main wavelength belonging to the same wavelength group as the light irradiated to the subject,
• the luminance of the subordinate image obtained as a result of irradiating the subject with light belonging to the first wavelength group or the second wavelength group, the subordinate image being obtained based on a subordinate wavelength belonging to the same wavelength group as the light irradiated to the subject and has a different wavelength from the main wavelength.
