ABSTRACT:
A digital imaging-based bar code symbol reading system comprising: an area image formation and detection subsystem having a CMOS area image sensing array with an image capture mode; a LED-based illumination subsystem for producing narrow-band illumination; and a narrow-band transmission-type optical filter subsystem integrated within the hand-supportable housing of the device. During the image capture mode, and only when substantially all rows of pixels on the CMOS area image sensing array are enabled and simultaneously ready for photo-integration, the LED-based illumination subsystem is activated so as to produce narrow-band illumination into the FOV of the area image formation and detection subsystem while the automatic light exposure measurement and illumination control subsystem automatically measures the light exposure incident upon a central portion of the FOV, and controls the time duration that narrow-band illumination is produced from the LED-based illumination subsystem.
