Electronic transparency method and apparatus
First Claim
1. An electronic transparency apparatus comprising:
- first processor means for generating and supplying video data;
a LCD display unit having;
1) a liquid crystal display;
2) input means for receiving said video data from said first processor means;
3) frame buffer means, coupled to said input means, for storing said video data as a frame of video data; and
4) output buffer means, coupled to said frame buffer means and said liquid crystal display, for receiving said frame to video data from said frame buffer means and for presenting said frame of video data to said liquid crystal display;
a memory module having;
1) second processor means coupled to said frame buffer means for selectively enabling a first and second data path for said video data; and
2) a storage device, coupled to said second processor means and said frame buffer means whereby said apparatus displays said video data from said first processor means when said first data path is enabled and said storage device adapted to selectively capture and store said video data as a plurality of frames of video data when said second path is enabled; and
3) means for editing and subsequently displaying selected ones of said stored frames of video data on said apparatus.

Abstract
An electronic transparency device is provided with a memory in which a plurality of frames of video data ("slides") can be stored. The apparatus includes a control microprocessor which can cause predefined sequences of slides to be presented on the LCD panel automatically. These slide "shows" are defined by the user using a hand held remote control unit in conjuntion with menus displayed on the LCD panel in window fashion by the microprocessor. The user can specify the duration that each slide in a sequence is to be shown, the video transition by which it is to be introduced, the degree of "windowshading" with which it is to be displayed, etc. Once a show is defined, it can be instituted and controlled from the remote control unit. Among other numerous features, the transparency also includes a pointer that can be superimposed on the display and controlled by the remote control unit. This pointer can be used to define certain portions of the screen that are to be displayed in highlighted fashion.
