Abstract: An interactive presentation system uses a presentation computer, a computer-controlled image projector and a projection screen, in which control of the presentation computer is accomplished by using a wireless optical pointer that projects an encoded control cursor onto the projection screen. The projected screen images are monitored by a video camera, and the control cursor is scanned, detected and decoded for emulating various keyboard commands and/or pointing device (mouse, touch pad, track ball) position-dependent cursor operations. The control cursor is reliably detected and its coordinate location is accurately determined on the basis of one or more primary image attributes, for example image intensity and image repetition rate, both of which are independent of monitoring angles and pointing device projection angles, and one or more secondary image attributes, for example image size, color and pattern.

Abstract: A document camera is used to show image of an object on a display. In the document camera, a first image data of the object obtained by a video-capturing device is derived into a second image data and a third image data by an image processor in response to a zoom operation, wherein the second image data results in a zoomed image of the object and the third image data results in a scaled image of the object. In response to the zoom operation, there is also a mark frame data generated by a position information controller, which results in a mark frame. The zoomed image, scaled image and mark frame are then synthesized into a combined image by an image synthesizer, and the mark frame superimposes the scaled image to indicate a result of the zoom operation.
