What are the overhead projectors that do not stipulation transparencies (reflects from weekly image) call?
Answers: The correct term is episcope. You may also find them described as epidiascopes. A diascope is the correct label for, for example, a slide projector and an epidiascope combines the functions of the episcope (where a bright light illuminate an opaque goal and the image is projected near a lens onto a screen) and a diascope (where a light is shone through a transparent photograph or drawing and is projected beside a lens.)
Both of these, of course, come long before the invention of digital cameras and LCD projectors and their place have now mostly be taken by a camera/digital projector set up.
Is it LCD projectors?
