摘要
The present disclosure provides systems and methods for acquiring images of a code at variable distances. The systems and methods utilize variable focus lenses to provide operating conditions where acquisition of images of the code at shorter distances provides a wider viewing angle and lower magnification than acquisition of images of the code at longer distance. In some cases, the distances for code image acquisition can be predefined. The predefined distances can have corresponding predefined variable focus lens settings to facilitate image acquisition.
