摘要： PURPOSE:To make an image pickup face and a display face flush and to make the level of an image pickup system the same with that of a camera system by regularly dividing an input and output interface face into the display face and the image pickup face by the polymer of an optical fiber within a two-dimensional space. CONSTITUTION:The plural optical fibers are regularly arrayed and fixed, one edge face A is used as the input and output interface face of a video, and the other edge face side is fixed as edge faces B1 and B2 by collecting the optical fiber by each 1/2. Then, the B1 face is adhered to a camera 2 and the B2 face is adhered to a display device 3. Then, an input light to which the 172 sub-sampling of the edge face A is operated, is guided to the Bq face, so that the input of the video equivalent to the position or the edge race A can be operated by the camera 2. Also, the luminance change of the picture element of the video displayed at the display device 3 is guided to the edge face A, and the picture element can be reproduced at the edge face A. Thus, the image pickup face and the display face can be made flush, and the level of the image pickup element can be the same with that of the camera system.

摘要： PURPOSE:To enlarge and display the picture, which is displayed on a liquid crystal display element, on a screen with a high definition. CONSTITUTION:A prismatic mirror 1 adjacent to a projection lens 3 is arranged, and two side faces of this mirror on the projection lens side are used as reflection faces RP1 and RP2, and a picture to be projected on liquid crystal display elements 21 and 22 is preliminarily divided into two right and left parts, and right and left half pictures are displayed on liquid crystal display elements 21 and 22 through picture signal lines 71 and 72. Pictures on liquid crystal display elements 21 and 22 are projected and displayed on right and left halves of a screen 6 respectively and are synthesized as if the original picture were projected from one liquid crystal display element, and the picture is displayed with a high definition by double liquid crystal display elements.

摘要： PURPOSE:To receive a high definition picture with a sufficient picture element number. CONSTITUTION:One optical division means or over (21-23) is arranged in the rear side of a lens 3 and an image of an object 4 is formed to plural positions. That is, sensor mount boards 11-14 with solid-state area sensors arranged in 2-dimension are arranged in the image forming positions respectively, and an image area between the sensors unable to be picked up by the sensor arranged in one image forming position is picked up by the sensor arranged to the other image forming position, and the image is picked up so as to supplement the area unable to be picked up by the sensor of the other image forming position to pick up the image of the entire object 4. That is, number of picture elements required for image pickup is increased by arranging lots of sensors in the image forming area of the lens 3 to attain high definition image pickup.

摘要： PURPOSE:To miniaturize the above device and to display a picture with a wide view on a large screen by segmenting only the image of an observer among the observer image and a display screen image to be photographed through a half mirror. CONSTITUTION:A half mirror 2 is arranged in front of the display screen of a display device 1 so that the half mirror 2 can separate a display screen picture optical path 5 for the figure picture on a communicating party side projected on the display screen and an observer image optical path 6 for an observer 4 projected on the half mirror. The two inputs of an input video signal 7 to the display device 1 and an output video signal 8 from a photographing device (TV camera) 3 are inputted to a signal processor 9 for generating a differential signal so as to be outputted as an observer video signal 10 from the device to a communicating party side display device at a distant place. After the differential video is obtained, only the video of the observer is transmitted to the communicating party side at a suitable luminance level. Thus, it is not necessary to incline the half mirror almost at 45 deg., the device is miniaturized, and the video of the communicating party can be displayed with wide view on the large screen.

摘要： PURPOSE:To miniaturize an image pickup device itself without lowering presence by moving a camera to a range, where the camera does not interrupt a party figure image displayed on a display device, and displaying the range to be interrupted by the camera corresponding to the setting position of the camera. CONSTITUTION:A CCD supercompact camera having a supercompact camera head part 8 is used, the image of the observer is picked up while arranging the supercompact camera on the front face of a display device 1, and a display face hidden by the supercompact camera is masked by a window called camera window 15. Then, the display position of the camera window 15 is moved corresponding to the setting position of the supercompact camera by a transparent supercompact camera supporting board 9 and by displaying the camera window 15 at a position where the window does not interrupt the figure image of the communicating party, the image is picked up with the aligned glance. Thus, the device is miniaturized, and the presence or the expression can be satisfactorily read.

摘要： PURPOSE:To prevent the transfer of data file information similar to an opposite existing in a present floppy disk by controlling a data file to be transferred by means of a contents file. CONSTITUTION:The contents file 7 to which a file identifier to be transferred is inputted is prepared in the floppy disk where a data file 6 is described. Prior to the transfer of data file information 6, the contents file 7 is reciprocally transferred. The file identifier registered in the contents file of the opposite and the file identifier in the present floppy disk are collated from the transferred contents file 7. When data file information similar to self data file information exists in the contents file of the opposite as the result of collation, the transfer of data file information 6 is not requested to the opposite. Thus, only the data file required can be transferred. Correspondence to plural conference contents and conference opposites is attained by using the same floppy disk only by rewriting the contents file 7.

摘要： PURPOSE:To easily perform the expansion, compression, rotation, and deformation of an image by dividing a halftone image to bit planes, and performing vector encoding at every bit plane as a binary image. CONSTITUTION:The halftone image is digitized by an A/D conversion means 301, and is divided into the bit planes by a bit plane division means 302. Next, the vector encoding is performed by extracting the contour of the bit plane at every linked bundle of bits 1 by a vector encoding means 303. A sub framing means 304 receives information with respect to the weight of the bit plane from the bit plane division means 302, and performs sub framing by adding vectorized data inputted from the vector encoding means 303, and correspondence between the weight and encoded data is performed at every bit plane. A framing means 305 performs framing by unifying sub frames at every bit plane as the encoded data of one image.
