Video and digital Camera

Video and digital cameras use electronics, generally a charge coupled device or sometimes a CMOS sensor to capture images which can be transferred or stored in tape or computer memory inside the camera for later playback or processing. Traditional cameras imprison light onto photographic film or photographic plate. A video camera is a kind of movie camera which stores images onto magnetic tape. Cameras that capture a lot of images in sequence are known as movie cameras or as cine cameras in Europe; those designed for single images are still cameras. However these categories overlap, as still cameras are often used to capture moving images in extraordinary effects work and modern digital cameras are often able to trivially switch between still and motion recording modes. Cameras that take 3D photographs are called as stereo cameras. Stereo cameras for creation 3D prints or slides have two lenses side by side. Stereo cameras for making lenticular prints have 3, 4, 5, or yet more lenses.
