IMAGE READING DEVICE CAPABLE OF PRODUCING ILLUMINATION INCLUDING A CONTINUOUS, LOW-INTENSITY LEVEL ILLUMINATION COMPONENT AND ONE OR MORE PULSED, HIGH-INTENSITY LEVEL ILLUMINATION COMPONENTS

摘要

An image reading device includes an illumination system and a processor that causes the illumination system to produce illumination according to an illumination period having a continuous or substantially continuous, illumination sub-period and at least one pulsed, illumination sub-period. The illumination period allows the image reading device to determine a proper exposure for imaged indicia by sectioning a single frame into individual exposures.
