ABSTRACT:
In one embodiment, a scanning device includes a light source configured to selectively illuminate an area of interest and a light sensitive receiver configured to receive light from the light source and generate signals based on the received light. Control logic is configured to power the light source at a power level, generating mid-tone-scan signals at the light sensitive receiver. Calibration logic is configured to determine a calibration factor for a selected pixel based data including the mid-tone-scan signals.
