PROBLEM TO BE SOLVED: To perform zoom-up and panning, etc., without physically moving a camera system by wide-band transmitting image data obtained by a camera provided with a wide angle lens and performing an image conversion processing on a transmission side or a reception side. SOLUTION: The camera 2 is provided with the wide angle lens (fisheye lens, preferably) and digitizes and outputs the image data obtained by a CCD sensor. An image processing circuit 3 compression-processes the image data and a transmitter 4 transmits the entire signals including voice interleaved by a controller 5 through a wide band width network to a reception part 20. A receiver 21 receives the signals from plural video sources and the controller 24 supports the entire video/audio system. The image processing circuit 22 corrects the distortion of a spherical lens from received wide angle images and converts them to plane images. Also, corresponding to an instruction from an input device 25, a part of the images is selected and the images are re- mapped as if a still camera is moving. |
