A distinguishing device for dental plaque and dental calculus includes a light-emitting diode, an image sensing unit, and a processor. The light-emitting diode movies in a first direction and is separated from teeth in an oral cavity by a predetermined distance in a second direction. The second direction is perpendicular to the first direction. The light-emitting diode generates a blue light to illuminate the teeth, so that dental plaque on the teeth generates a first autofluorescence and dental calculus on the teeth generates a second autofluorescence. The image sensing unit is configured to sense the first autofluorescence and the second autofluorescence. The processor is coupled to the image sensing unit to distinguish a dental plaque area from a dental calculus area on the teeth according to the first autofluorescence and the second autofluorescence.

A video conference system built in an internet protocol (IP) network is provided. The system has a multimedia capturing unit, a DECT telephone, and a video conference terminal apparatus. The DECT telephone is utilized to perform video conferencing with the video conference terminal apparatus by receiving and transmitting sounds. The DECT telephone is further utilized to control the video conference terminal apparatus to capture a target image in the video signals from other users in the video conference. The video conference terminal apparatus updates the phonebook image in the phonebook database thereof with the target image.
