5.3 - Windowing

If only one size of bar code is being scanned in an application, the CR3 can be optimized to reduce processing time by adjusting the viewing frame within the ﬁ eld of view of the image (ONLY FOR SXGA MODE).

By reducing the vertical window value of the imager to 200 pixels, 1-D codes are processed more quickly. Because only a horizontal strip of a 1-D code is needed to be decoded, using a narrow strip of the imager is all that is needed. The area above and below the 200 pixels, which is always in the center of the imager, is ignored. This approach reduces the number of pixels that must be processed.

Windowing can improve the processing time of 1D and 2D codes.

You may negatively impact reader performance if the window size is too small. If it is necessary to have the reader farther away than normal to read the code, the window may be too small.

Reading other types of codes, especially large codes, may be difﬁ cult while using this setting.
