Method and System for Reducing Perceived Illumination Flicker in Multi-Sensor Barcode Scanners

Abstract: the present disclosure describes methods and systems for reducing perceived flickering in multi-sensor barcode scanners. the proposed solution introduces a dummy illumination pulse during transitions between sensors or frames, mitigating noticeable flicker. the timing, duration, and spacing of the dummy pulse are calculated based on factors such as the next expected exposure, frame rate, and/or previous exposure. this solution can be applied to a variety of barcode scanners, including those with different sensors for near and far scanning or those using different leds for capturing frames. the system also potentially includes an illumination boost circuitry that recharges during the generation of the dummy illumination pulse, preventing system faults. the method offers an effective solution to illumination flicker in multi-sensor barcode scanners without causing unnecessary delays or system errors.
