The method of CCD exposure time control based on driver timing was proposed for the situation of the high performance CCD imaging detector without electronic shutter. The charge will be drained quickly in the excess period by increasing the charge excretion state after the horizental readout under the certain frame frequency. It can control the CCD exposure time effectively,and overcome the problem the CCD minimum exposure time is equal to the readout time. Results show that the booming resistance of the large aperture static imaging spectrometer is well improved and the non-linearity of the method is 4.61%.
