Abstract: Provided is a circuit assembly that does not need to include test circuit components that are mounted on a control board in a one-to-one relationship with electronic components. A circuit assembly includes a plurality of electronic components; a plurality of control terminals electrically connected to the plurality of electronic components; a holding member that has insulating properties and holds the plurality of control terminals; and a control board configured to output signals to the electronic components via the control terminals, wherein each of the control terminals includes: a first terminal body portion connected to the control board: a pad portion that is electrically connected to the first terminal body portion, is provided along the holding member, and is exposed from part of the holding member; and a second terminal body portion electrically connected to the pad portion and the corresponding electronic component.

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.
