Abstract
An image sensing device for a TV camera and method of driving the same is disclosed whereby the effective charge accumulation time in each light-sensing row in the imaging area can be reduced thereby eliminating fuzzy images produced when fast moving objects are picked up. The driving circuit of the imaging device gives the sensor a shutter function of less than 1/60 second and up to 1/2000 second exposure time without changing the structure of the sensor. There is provided a method in which charges accumulated in each row of the light-sensing elements are taken out and discarded at an optional time during an active video period, leaving an effective charge accumulation period of less than 1/60 second.
