发明名称 AUTO-EXPOSURE METHOD USING CONTINUOUS VIDEO FRAMES UNDER CONTROLLED ILLUMINATION
摘要 A strobe illumination control process for use in a digital image capture and processing system includes illuminating an object in the field of view with different pulses of illumination over a pair of consecutive video image frames, detecting digital images of the illuminated object over these consecutive image frames, and decode processing the digital images. In a first illustrative embodiment, upon failure to read a symbol 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 is adjusted during subsequent image frames. In a second illustrative embodiment, upon failure to read a symbol 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 illumination is adjusted during subsequent image frames.
