Video Cameras and Frame Grabbers
Video cameras are similar to digital cameras
Except that a video camera takes image after image continuously
The output from many video cameras is analog and requires digitizing circuitry to make the image usable in a computer
Digital camcorders are now available
Frame grabber software allows the capture of a single still image from the video stream
Frame grabbed images are of rather low resolution, however, ៀ-90 dots/inch
