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.

主权项

1. An image reading device comprising:
an illumination system; and a processor for controlling the illumination system; wherein the processor causes the illumination system to produce illumination according to an illumination period comprising a continuous or substantially continuous, illumination sub-period and at least one pulsed, illumination sub-period; wherein the continuous or substantially continuous, illumination sub-period causes the illumination system to produce a continuous or substantially continuous, illumination component and the at least one pulsed, illumination sub-period producing at least one pulsed, illumination component.
