Abstract
An optical information reading apparatus includes: a light source; an imaging element configured to repeat a first exposure and a second exposure; and a control part configured to control the light source such that a gravity center of a light quantity of exposure illumination at a time of the first exposure and a gravity center of a light quantity of dummy illumination before and after the second exposure or before the second exposure are at an even time interval.
Claims6
An optical information reading apparatus comprising:
- a light source;
- an imaging element configured to repeat a first exposure and a second exposure;
- and
- a control part configured to control the light source such that a gravity center of a light quantity of exposure illumination at a time of the first exposure and a gravity center of a light quantity of dummy illumination before and after the second exposure or before the second exposure are at an even time interval,
- wherein the control part is further configured to turn off the light source during the second exposure, and
- wherein the control part is further configured to control the light source such that a time interval between successive illuminations of the light source is at an uneven time interval.
