Method and apparatus for exposure level setting in machine vision systems |
摘要 |
In a solid state image sensor having a pixel array, a first frame is imaged using varying exposure times in a series of zones. The exposure time for a subsequent frame is selected from the results of the first frame, The exposure times are controlled in a rolling blade manner by controlling the number of lines between reset and readout. The sensor is particularly suited to use in bar code readers.
