Extended working range dataform reader including fuzzy logic image control circuitry
Abstract
A portable data collection system is disclosed. The system includes a dataform reader module having a board camera electrically coupled to a control and decoder board in an open loop feedback configuration. The control and decoder board includes fuzzy logic image control circuitry which analyzes a captured frame of a video image including a dataform produced by the board camera. Based on the analysis of the captured frame, the fuzzy logic image control circuitry generates control signals to adjust operating parameters of the board camera such that an image suitable for decoding is produced.
