There is described a decodable indicia reading terminal which in one embodiment can capture and process a certain (e.g., a first) and a subsequent (e.g., a second) frame of image data, wherein the certain and the subsequent frames have different imaging attributes. In one embodiment the attributes between certain and subsequent frames are differentiated in that the certain frame represents light incident on pixels of a first image sensor and the subsequent frame of image data represents light incident on pixels of a second image sensor spaced apart from the first image sensor. Additionally, or in the alternative, the attributes between certain and subsequent frames can be differentiated in that the first frame represents light incident on an image sensor under a first illumination profile and the subsequent frame represents light incident on pixels of an image sensor under a second illumination profile. In one embodiment imaging attributes of a frame subject to decoding are maintained constant for each frame subject to processing during a time that a trigger signal remains active. In one embodiment the certain and subsequent frames can be processed to yield partial decoding results and the partial decoding results can be combined to form a complete decoding result.

A hybrid-type bi-optical bar code symbol reading system having a vertical housing section with a vertical scanning window, and a horizontal housing section with a horizontal scanning window, from which laser scanning planes are projected and intersect within a 3D scanning volume defined between the vertical and horizontal scanning windows. An automatic object edge-motion detection subsystem is provided for detecting the entry and exit of objects at the edge of the 3D scanning volume, and generating control signals in response thereto. A digital imaging subsystem is supported within the system housing and automatically projects a field of view (FOV) within the 3D scanning volume in response to control signals generated by the automatic object edge-motion detection subsystem and timer settings managed by a system controller.

A hybrid-type bi-optical bar code symbol reading system having a vertical housing section having a vertical scanning window and a horizontal housing section having a horizontal scanning window, from which laser scanning planes are projected and intersect within a 3D scanning volume defined between the vertical and horizontal scanning windows. A digital imaging module is supported within the vertical section of the system housing and automatically projects a field of view (FOV) within the 3D scanning volume when an object is detected in close proximity to the vertical scanning window of the system, providing an automatically-triggered digital imaging region in close proximity to the vertical scanning window.

A solid-state imager is mounted at a point-of-transaction workstation for capturing images of diverse targets useful for customer identification, customer payment validation, and operator surveillance. The imager is manually or automatically triggered and is operated at high speed to resist image blurring due to relative movement between the target and the imager.

A hardware identification system is provided in a bar code reading arrangement including a main body and a plurality of modular detachable scanning heads connectable to the main body dependent on the application desired for the reader. Each of the heads includes a voltage divider dividing identification voltage and the main body includes a microprocessor including an analog to digital converter which reads the identification voltage, converts it to a digital signal and compares the identification voltage against a look-up table of identification voltages and their associated hardware element to identify the module type. Alternatively, or in addition, the module may be similarly configured to identify the main body by virtue of an identification voltage defined by a voltage divider in the main body. Alternatively the hardware identification system includes an electronic subassembly such as a PC board used for example in computer systems for automatic identification of hardware.
