A line scan CCD optical integration time self-adaptive control method, which contains 1, estimating line scan CCD corresponded optical integration time according to relative parameter of line scan CCD output signal, 2, controlling line scan CCD driving time sequence generator according to estimated optical integration time and generating the driving pulse sequence needed in CCD normal work, said driving pulse sequence containing integration pulse sequence, transferring pulse sequence and reset pulse sequence, 3, line scan CCD output adjusted optical integration time signal by driving of pulse sequence, preprocessing and calculating said signal to extract correlation parameter of line scan CCD output signal, 4, comparing the correlation parameter of extracted CCD line scan output signal with preset threshold value, when the value is exceeds the threshold value, adjusting again by step 1, 2, 3, until the parameter is in preset threshold value range, 5, automatically completing adjustment of optical integration time.
