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.
A dataform reader comprising: a) a board camera including a two dimensional photosensor array comprising a set of pixels and control circuitry for generating a video signal representative of an illumination content on each pixel in the set of pixels over an exposure period; b) the board camera contr
A dataform reader comprising: a) a board camera including a two dimensional photosensor array comprising a set of pixels and control circuitry for generating a video signal representative of an illumination content on each pixel in the set of pixels over an exposure period; b) the board camera control circuitry including a gain control signal input and an exposure period control signal input; c) an analog to digital converter coupled to the board camera, the analog to digital converter receiving the video signal and generating gray scale values; and d) a control unit coupled to the board camera and the analog to digital converter to receive the gray scale values and analyze a portion of the gray scale values, generate at the least one of a gain control signal input to the board camera control circuitry gain control signal input and an exposure period control signal input to the board camera control circuitry exposure period control signal input.
