Abstract
An imaging device has a photosensitive array, a vertical transfer CCD array, a horizontal transfer CCD, a drain region, drain gates, a drive circuit and a processing circuit. An electric charge accumulated in the photosensitive array is first transferred to the vertical transfer CCD array, and then transferred from the vertical transfer CCD array to the horizontal transfer CCD. The electric charge held in the horizontal transfer CCD is transferred to the drain region at a predetermined timing defined by to a slow motion ratio N. The slow motion operation can be changed independently of the frequencies of the CCD drive signals. Therefore, the power consumption is much reduced and a slow motion ratio can be obtained.
