Abstract

In a camera-assisted presentation system, a microcomputer activates a motion detecting module to detect a motion of an object, based on a variation in luminance of image data representing a material photographed by a photographing module. In the case of detection of a motion of the object, the microcomputer controls an output control module to prohibit transfer of the image data to an image output module. Image data photographed immediately before detection of the motion is kept in an output image storage sub-module of the image output module. This arrangement effectively prevents any action of setting the material from being undesirably displayed on an external display unit, thus ensuring smooth presentation with improved display of images during the actions of setting the material in the camera-assisted presentation system.
