    • PROBLEM TO BE SOLVED: To provide an indicia reading terminal achieving high-speed decoding even if the number of pixels of an image sensor increases.
      SOLUTION: There is described an indicia reading terminal that is operative to process a frame of image data for attempting to decode a decodable indicia. A frame can be a frame that is among a succession of frames for subjecting to processing subsequent to and during a time a trigger signal is active. Such a succession of frames can include zero or more binned frames, zero or more unbinned frames, zero or more windowed frames, and zero or more unwindowed full frames. An indicia reading terminal can also include a variable focus imaging lens. Control of the variable focus imaging lens can be provided so that during an exposure period for a binned frame the variable focus imaging lens is set to a short range focus setting and further so that during an exposure period for a windowed frame the variable focus imaging lens is set to a long range focus setting.

    • 要解决的问题:即使图像传感器的像素数量增加,也提供实现高速解码的标记读取终端。 解决方案:描述了一个标记读取终端,其操作用于处理图像数据帧以尝试解码可解码的标记。 帧可以是在触发信号有效的时间之后和在触发信号有效的时间之间进行处理的帧之间的帧。 这样的一系列帧可以包括零个或多个binned帧,零个或多个未匹配的帧,零个或多个窗口帧,以及零个或多个未窗口的全帧。 标记读取终端还可以包括可变焦点成像透镜。 可以提供可变焦距成像透镜的控制,使得在对于分类框架的曝光期间,可变焦距成像透镜被设置为短距离聚焦设置,并且进一步使得在窗框的曝光时段期间,可变焦距成像透镜 设置为长焦距设置。 版权所有(C)2010,JPO&INPIT
