Abstract
An imaging device outputs imaging data captured with a predetermined exposure time, and a brightness determination unit determines whether the brightness of the imaging data is within a predetermined range. Re-imaging is performed with the exposure time changed when the brightness of the imaging data is not within the predetermined range. The re-imaging is performed with the exposure time lengthened when the brightness of the imaging data is less than a determination value, and the re-imaging is performed with the exposure time shortened when the brightness of the imaging data is saturated.
