    • A graphical code reader is disclosed. The graphical code reader includes an infrared light-emitting diode and a red light-emitting diode. The graphical code reader also includes an image sensor. A lens is positioned to focus reflected light on the image sensor. The graphical code reader also includes a processor and memory in electronic communication with the processor. Instructions are stored in the memory. The instructions are executable by the processor to implement a method that involves illuminating the infrared light-emitting diode at an infrared illumination intensity level and illuminating the red light-emitting diode at a red illumination intensity level. The method also involves capturing a digital image for processing. The digital image is an electronic representation of an optical image formed on the image sensor. The method also involves processing the digital image to attempt to decode a graphical code within the digital image.
    • 公开了图形代码阅读器。 图形代码读取器包括红外发光二极管和红色发光二极管。 图形代码读取器还包括图像传感器。 定位镜头以将反射光聚焦在图像传感器上。 图形代码读取器还包括处理器和与处理器电子通信的存储器。 指令存储在内存中。 该指令可由处理器执行,以实现一种方法,其涉及以红外照明强度水平照射红外发光二极管并以红色照明强度水平照射红色发光二极管。 该方法还涉及捕获数字图像进行处理。 数字图像是形成在图像传感器上的光学图像的电子表示。 该方法还涉及处理数字图像以尝试对数字图像内的图形代码进行解码。
