ABSTRACT:
In a picture telephone, an apparatus is provided which images the face of an operator in a natural manner for a conversation, with an eye height at which the operator looks at an image expressing a partner of the conversation. A number of photodiodes are disposed each adjacent to each pixel electrode, on surfaces facing each other of a pair of substrates between which a liquid crystal of a transmission type active matrix liquid crystal display apparatus is interposed. Outputs from the respective photodiodes are read out by a so-called inter-line transmission method which utilizes a scanning function of a CCD (charge coupled device).
