A portable data collection system including a dataform reader module (10) having a board camera electrically coupled to a control and decoder board (18) in an open loop feedback configuration. The control and decoder board (18) includes fuzzy logic image control circuitry (18) which analyzes a captured frame of a video image including a dataform produced by the board camera (14). Based on the analysis of the captured image, the fuzzy logic image control circuitry (18) generates control signals to adjust operating parameters of the board camera (14) such that an image suitable for decoding is produced.
