Abstract

An electronic shutter camera with full frame resolution employs a progressively scanned interline transfer charge coupled device for generating full frame images of objects moving past an observation point either asynchronously in response to an external trigger signal or synchronously with internal timing. The image charges accumulated on the pixel regions of the CCD are discharged once per frame time, and the pixel regions are also initially discharged prior to the beginning of an image charge integration period to remove noise. A special double pulse mode enables the shutter speed to be specified by externally generated double trigger pulses, with the spacing between pulses specifying the desired shutter time. Manual selection of a wide range of shutter speeds is also provided. Each image frame is stored in a digital memory and is output as either interlaced or non-interlaced analog or digital video.
