SCANNING SYSTEM AND METHOD FOR CONTROLLING AIMING LIGHT SOURCE

Document Type and Number:

WIPO Patent Application WO/2022/016314

Kind Code:

A1

Abstract:

A scanning system and method for controlling an aiming light source (7), comprising: an image sensor (4), for sequentially exposing a pixel array by means of a rolling shutter to acquire a target image, the pixel array comprising effective pixels (5) and non-imaging pixels (6), the effective pixels (5) being pixels actually used for image decoding, the non-imaging pixels (6) being pixels that are not actually used for image decoding, and the aiming light source (7) being used for projecting an aiming pattern (8) to aim at a target; and a control unit (12), used for controlling the image sensor (4) and the aiming light source (7), so that the aiming light source (7) is turned off during the exposure time of the effective pixels (5), and the aiming light source (7) is turned on during at least part of the exposure time of the non-imaging pixels (6).
