20120150589 | BAR CODE SYMBOL READING SYSTEM SUPPORTING VISUAL OR/AND AUDIBLE DISPLAY OF PRODUCT SCAN SPEED FOR THROUGHPUT OPTIMIZATION IN POINT OF SALE (POS) ENVIRONMENTS - A POS-based bar code symbol reading system that reads bar code symbols on objects being passed through the 3D imaging or scanning volume supported by the system, and employs one or more object motion sensors (e.g. imaging based, IR Pulse-Doppler LIDAR-based, ultra-sonic energy based, etc.) to (i) measure or estimate the speed of objects being manually passed through the 3D imaging or scanning volume by the system operator, and (ii) visually and/or audibly display object scanning speed measures or estimates to provide the system operator with feedback for optimizing system throughput. The POS-based bar code symbol reading system has a performance advantage that leads to quicker customer checkout times and productivity gain that cannot be matched by the conventional bar code symbol scanning technology. | 06-14-2012 |
20120199654 | AUTO-EXPOSURE METHOD USING CONTINUOUS VIDEO FRAMES UNDER CONTROLLED ILLUMINATION - An adaptive strobe illumination control process for use in a digital image capture and processing system. In general, the process involves: (i) illuminating an object in the field of view (FOV) with several different pulses of strobe (i.e. stroboscopic) illumination over a pair of consecutive video image frames; (ii) detecting digital images of the illuminated object over these consecutive image frames; and (iii) decode processing the digital images in an effort to read a code symbol graphically encoded therein. In a first illustrative embodiment, upon failure to read a code symbol graphically encoded in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the exposure time (i.e. photonic integration time interval) is automatically adjusted during subsequent image frames (i.e. image acquisition cycles) according to the principles of the present disclosure. In a second illustrative embodiment, upon failure to read a code symbol graphically encoded in one of the first and second images, these digital images are analyzed in real-time, and based on the results of this real-time image analysis, the energy level of the strobe illumination is automatically adjusted during subsequent image frames (i.e. image acquisition cycles) according to the principles of the present disclosure. | 08-09-2012 |
