Video camera apparatus having a solid-state image sensor and a high shutter speed

摘要

A high shutter speed video camera has an objective lens and a CCD. The CCD is defined by a photosensor array for producing charge signals representing the image formed thereon by the lens, and a shift register for storing and moving the charge signals in a predetermined direction in response to drive pulses. A driver is provided for sequentially producing a first read pulse signal for effecting the transfer of the charge signals from the photosensor array to the shift register, high speed vertical drive pulses for moving the charge signals in the shift register at a high speed until all the charge signals are removed from the shift register, second read pulse signal for effecting the transfer of the charge signals from the photosensor array to the shift register, and normal speed vertical drive pulses for moving the charge signals in the shift register at a normal speed until the charge signals are removed from the shift register. Since the time interval between the first and second read pulse signals is selected to be very short, such as 1/1000 second, the image picked up by the CCD during this time interval is identical to an image picked up with a shutter speed of 1/1000.
