CCD solid-state pickup device with controlled shutter pulse generation
摘要:
A CCD solid-state image pickup device includes a CCD solid-state image pickup element which includes a sensor array comprising a number of one-dimensionally arranged photosensitive units, a read-out gate, a transfer register and electronic shutter means comprising a drain gate and a drain region, the read-out gate and the transfer register being disposed at one side of the sensor array and the electronic shutter means being disposed at the other side of the sensor array, an output level comparator for comparing the output level of each image pickup signal from the CCD solid-state image pickup element with the output level of a predetermined reference signal to output a comparison signal, and a shutter-timing generating unit for generating an output timing of a shutter pulse for a predetermined period on the basis of the comparison signal from the output level comparator, and supplying the shutter pulse to the electronic shutter means of the CCD solid-state image pickup element at the generated output timing.
