Visualizer/ Document Camera

Visualizer/ Document Camera also known as Visual Presenters, Digital overheads, or Docucams, are real-time image capture devices for displaying objects to large audience. Document Camera is able to magnify and project Images of actual, three-dimensional objects/ transparencies.

They are, like, high resolution Web Cams, mounted on arms so as to facilitate their placement over a page. This allows a Teacher, Lecturer or Presenter to write on a sheet of paper or display a 2-D/ 3-D Object while the audience watches. Theoretically, all objects can be displayed by document camera. Most objects are simply placed under the camera. The camera takes the picture which in turn produces a live picture using a projector or monitor.

Different types of document camera/ visualizer allow great flexibility in terms of placement of objects. Larger objects, for example, can simply be placed in front of the camera and the camera rotated as necessary, or a ceiling mounted document camera can also be used to allow a larger working area to be used.
