Abstract
When analyzing captured images and reading the optical information contained within them, the system allows for a wide range of exposure time options while appropriately adjusting the imaging conditions. [Solution] When an imaging unit periodically captures an image in each frame and analyzes the image to read the optical information contained therein, the amount of movement of the imaging unit per frame is estimated based on the images captured within a certain time range, and the imaging adjustment process 212 adjusts the imaging conditions, including at least one of the exposure time and illumination time (S113, S115). At this time, the upper limit of the value of at least one of the above items set in the imaging adjustment process 212 is determined based on the estimated amount of movement of the imaging unit per frame (S112, S114).
