    摘要： A system generating composed signals of stable multiple pictures reduces a scale of hardware required for forming video signals sent from a plurality of terminals into one composed picture on a video conference system. A system generating composed signals of multiple pictures for use in a video conference system includes video conference terminals connected via a network, a multi-point control unit connected to the network for controlling transmission of video signals among the video conference terminals, and a multiple picture composer connected to the multi-point control unit for receiving video signals sent out from the video conference terminals through the multi-point control unit, and information showing a reducing ratio and display positions of the video signals. The multiple picture composer includes a scaling section reducing video signals corresponding to each of the video conference terminals according to the reducing ratio, and a gate circuit section controlling to output the video signals reproduced by the scaling section according to the display positions, thus generating composed signals of the video signals of the video conference terminals.

    摘要： In an image monitor apparatus for monitoring an image: a camera picks up an image; an emission control unit controls at least one light emitting element; an image signal acquiring unit performs analog-to-digital conversion of the image picked up by the camera so as to generate a digitized image signal, and stores the digitized image signal; a luminance examining unit examines luminance of the image represented by the digitized image signal, and determines whether or not the amount of light detected and stored in an image-pickup plane of the camera is appropriate; and a luminance control unit controls at least one of the camera and the luminance control unit so that the amount of light stored in an image-pickup plane becomes appropriate.
