Abstract
An image capturing device includes an image forming device including a sensor defining an optical reception axis, at least one reading distance, and a region framed by the sensor on a substrate at said at least one reading distance. An illumination device includes an array of adjacent light sources defining an optical illumination axis. The light sources are individually drivable, and each light source is adapted to illuminate an area of a size much smaller than the size of said region framed by the sensor. The illumination axis does not coincide with the reception axis. A driver of the light sources is adapted to drive the light sources so as to switch off at least the light sources that illuminate outside of the boundary of the region framed by the sensor on the substrate at said at least one reading distance.
