摘要： A hand-supportable digital imaging-based bar code symbol reader comprises: an automatic object presence detection subsystem; an image formation and detection subsystem employing a CMOS area-type image detection array; an LED-based illumination subsystem employing an LED illumination array to generate a field of narrow-band LED-based illumination within the FOV; an automatic light exposure measurement and illumination control subsystem employing LED illumination driver circuitry; an image capturing and buffering subsystem; an image-processing bar code symbol reading subsystem; an input/output subsystem; and a system control subsystem for controlling the subsystems. The automatic light exposure measurement and illumination control subsystem controls the LED illumination driver circuitry to expose the automatically detected object, to a field of narrow-band LED-based illumination only when substantially all rows of pixels in the CMOS image sensing array are in a state of integration, thereby enabling the image capturing and buffering subsystem to capture high quality digital images independent of the relative motion between the bar code symbol reader and the object.

摘要： A hand-supportable automatic digital imaging-based bar code symbol reading device comprises: an automatic object presence detection subsystem; an area-type image formation and detection subsystem having a narrow-area image-capture mode of operation; a LED-based illumination subsystem having narrow-area illumination mode of operation; an image capturing and buffering subsystem; and an image-processing bar code symbol reading subsystem. The automatic object presence detection subsystem automatically detects an object, and the LED-based illumination subsystem automatically illuminates the detected object in a field of narrow-area narrow-band illumination, while the area-type image formation and detection subsystem captures a narrow-area image thereof. The image-processing bar code symbol reading subsystem automatically and directly applies decode image processing operations on the captured image, in an outwardly-directed manner, referenced from the center of the captured narrow-area image, to automatically read a 1D bar code symbol on the detected object.
