Reading Device, Reading Method, And Non-Transitory Recording Medium

A reading device comprising:

• a light source configured to emit a first light band and a second light band towards a reading target object, the first and second light bands being different;
• an imager including multiple photoelectric conversion elements, each photoelectric conversion element configured to be sensitive to one of multiple light reception wavelengths, the imager configured to:
• receive light having the multiple light reception wavelengths reflected from the reading target object;
• output a first color read value of the reading target object with a first color having a first light reception wavelength of the multiple light reception wavelengths;
• output a second color read value of the reading target object with a second color having a second light reception wavelength of the multiple light reception wavelengths;
• output a third color read value of the reading target object with the second color having the first light reception wavelength;
• and
• circuitry configured to correct the first color read value based on the second color read value and the third color read value and output the corrected first color read value.

A reading method comprising;

• emitting light from a light source that emits a first light band and a second light band towards a reading target object, the first and second light bands being different;
• receiving light having multiple light reception wavelengths reflected from the reading target object by an imager including multiple photoelectric conversion elements, each photoelectric conversion element configured to be sensitive to one of the multiple light reception wavelengths;
• outputting a first color read value of the reading target object with a first color having a first light reception wavelength of the multiple light reception wavelengths;
• outputting a second color read value of the reading target object with a second color having a second light reception wavelength of the multiple light reception wavelengths;
• correcting the first color read value based on the second color read value;
• and
• outputting the corrected first color read value.

A non-transitory recording medium storing a plurality of instructions which, when executed by one or more processors, causes the one or more processors to perform a reading method comprising;

• emitting light from a light source that emits a first light band and a second light band towards a reading target object, the first and second light bands being different;
• receiving light having multiple light reception wavelengths reflected from the reading target object by an imager including multiple photoelectric conversion elements, each photoelectric conversion element configured to be sensitive to one of the multiple light reception wavelengths;
• outputting a first color read value of the reading target object with a first color having a first light reception wavelength of the multiple light reception wavelengths;
• outputting a second color read value of the reading target object with a second color having a second light reception wavelength of the multiple light reception wavelengths;
• correcting the first color read value based on the second color read value;
• and
• outputting the corrected first color read value.
