Image capturing device

An optical reader comprising an array of individually drivable, adjacent light sources, and a driver adapted to drive the light sources of the array in an illumination mode, an aiming mode, and a reading outcome indication mode, wherein:

• the light sources of the array are made in the form of an integrated circuit on a common substrate;
• and
• the driver switches on only a first subset of the sources during illumination mode and a subset of the sources of the first subset when in an aiming mode or in a reading outcome indication mode,
• wherein the optical reader includes an image forming device including a sensor including an array of photosensitive elements and defining a region framed by the sensor at a reading distance within a depth of field, the first subset of the sources corresponding only to those sources that must be switched on to illuminate the entire and only the region framed by the sensor, wherein the first subset of sources varies with the reading distance, and the subset of the first subset when in the aiming mode provides a visual indication of the region framed by the sensor.
