A system for selectively reading code symbols includes a code-symbol-capturing subsystem for acquiring information about code symbols within the code-symbol-capturing subsystem's field of view. The system also includes a code-symbol-decoding processor that detects a marked region of interest within the code-symbol-capturing subsystem's field of view. After initialization, the code-symbol-decoding processor decodes only those code symbols falling within the marked region of interest.

System and method for selectively reading code symbols

A portable data terminal including a processor, a plurality of system resources, data storage means configured to store a plurality of program instructions, the program instructions including at least one hardware device driver and at least one scan driver, an image engine including a host interface, an imager in communication with the host interface, an illumination assembly and an aimer assembly wherein the illumination and aimer assemblies are controlled by the processor according to instructions stored in the data storage means, and a data structure having at least one data type and at least one value, the data structure being defined by the scan driver wherein the scan driver is configured to modify the data structure and transfer at least one of the values of the data structure to the hardware device driver in order to manage acquisition and release of a system resource by the image engine.

Image engine with multiple drivers

A method of operating a bar code scanning system adapted for assembling information bearing indicia (IBI) information from partial scans of IBI data which may comprise some undecodable characters, the method comprising the steps of: converting light reflected from a target into output signals representative thereof utilizing an image sensor; illuminating the target utilizing an illumination source; directing light from the target to the image sensor array utilizing receive optics; determining if information contained in IBI within the target derived from the output signals is not decodable; transmitting an image of the IBI to a host processor if the IBI is not decoded.
