摘要：
The present invention relates to an indicia reading terminal operative to capture and process a succession of frames of image data during an operator activated read attempt. The succession of frames can comprise alternating frames, wherein the alternating frames can have first and second frame featurizations. The frames having the first frame featurization can have a first window position and the frames of the second featurization can have a second window position. In one embodiment, exposure of frames of the first featurization can be controlled according to a first exposure control process and exposure of frames of the second featurization can be controlled according to a second exposure control process. In one embodiment, gain that is applied to image signals of frames of the first featurization can be controlled according to a first gain control process and gain that is applied to image signals of frames of the second featurization can be controlled according to second gain control process.
