Definitions

  • the present arrangement provides a system and method for controlling the operation of a portable projection device.
  • projection devices were (and are) designed as non-mobile devices that are positioned in a room and project a series of audio-visual images on a screen that is viewable by individuals within the room and in the line of sight of the projected image.
  • these projection devices are precisely configured to minimize errors in the audio-visual images being displayed. Examples of these systems include but are not limited to movie theaters, professional meeting rooms, lecture halls and the like.
  • pico projectors A pico projector may be included in any handheld device that can selectively project at least one of an image or series of images on a surface. Moreover, it is important for the pico projector to be able to generate a clear image of sufficient quality on any type of surface. This may include, for example, a conventional display screen or a wall in a room. It is, therefore, necessary for the pico projector to compensate for any surface impurities when generating and projecting a display image.
  • a further drawback associated with pico projection relates to the nature of the device itself. Because the pico projector is naturally handheld and/or portable, the pico projector suffers from increased visual display errors as compared to a traditional projection device. The increased visual errors (e.g. noise, distortion, etc) in images projected by pico projectors result from the often sub-optimal positioning of the pico projector with respect to the surface on which the images are being displayed as well as the orientation of individuals viewing the image to the surface on which the image is displayed.
