A device that adds freeze-frame capability to camcorders or video cameras so that they can be used as a digital snapshot camera. The freeze-frame adapter is designed as an add-on module which connects to the battery receptacle of the video camera or camcorder. The snapshot module contains both the freeze-frame electronics and the battery and replaces the battery of the camcorder. The battery provides power to both the camcorder and the photo adapter module. No modifications of the camcorder are required. The video signal used as the source of images for the freeze-frame adapter is derived from the Audio-Video output of the camcorder. The unit is always on and ready for use whenever the camcorder is on. Still images can be acquired simultaneously to video. The viewfinder of the camcorder also operates as the viewfinder in the snap-shot mode. The image is captured by pressing a shutter button on the freeze-frame adapter. Images can be acquired while the camcorder is filming. Both motion and still images can be acquired simultaneously. Captured images can be downloaded into a computer via a standard serial or parallel port or other data transfer link.
