Poynting Products FS-2505 Digital Freeze Frame Camera 1984
In the mid 80's my company built a digital video camera for industrial applications which could acquire, store, and display a strobe illumimated image for high speed industrial inspection. We added a digital video memory to a CID TN2505 (GE) solid state camera. Solid State Imagers are, in fact, analog devices. This camera functioned by A/D converting the video signal, storing that data in digital memory, and then reading that digital memory to reproduce the video signal using a D/A converter. So, this camera just might be the first commercially available Digital Video Camera (ie,generating STANDARD RS-170 Video from DIGITAL memory). When the memory was updated, the video was real time, but when updating memory was inhibited, the video was a freeze frame image. We had been building external digital freeze frame buffers for the camera which was only 388 x 248, so when the 64K by 1 bit memory became available, we put the memory and camera together. We had the advantage of working with low resolution, but is was quite innovative.
