The Movie camera is a type of photographic camera which takes a rapid sequence of photographs on film; once developed this film can be projected as a motion picture. In contrast to a still camera which captures a single snapshot at a time, the movie camera takes a series of images, each called a "frame".The frames are later played back at a specific speed, called the "frame rate" (number of frames per second) to give the illusion of motion. Our eyes and brain merge the separate pictures together to generate the illusion, a phenomenon called the "persistence of vision".
Video cameras (not movie cameras) can broadly be classified into two categories : analog and digital. Analog cameras are of the "tube" type; they are bulky and generally used in professional studios. Digital cameras are of the "CCD type"; they are light and portable, and generally used for home/office purposes.
