摘要： PURPOSE:To facilitate change of variables installing a RAM capable of direct writing from the terminal of an operating section in the digital signal processing sections existing in a signal receiving section and a signal transmitting section. CONSTITUTION:Analog image information is inputted to the signal transmitting section 10 where the information is converted to a digital signal. The digital signal is encoded by using the prescribed variable in the digital signal processing section 112 and is inputted through a digital network 40 to the signal receiving section 20. The signal is decoded to the analog signal by using the prescribed variable in the digital signal processing section 212. The analog signal is inputted to the operating section 30. The variables, such as table value parameter, necessary for encoding and decoding are written into the RAM in the digital signal processing sections 112, 212 from a disk 33 possessed by the operating section 30. The change of the variables arising from the improvement of the image quality is easily executed in this way from the operating section 30.

摘要： PURPOSE: To avoid congestion of a communication network, to reduce the loads on the video reception processing of a communication terminal and to avoid the uniform degradation of video image quality as a result. CONSTITUTION: A distance/line-of-sight matching degree judgement part 110 judges the matching degree of the distance and the line of sight between the other self of a user and the other self of another person from the movement information of the other self of the user and the movement information of the other self of another person and requests video images to the other terminal. A video camera 102 photographs the video image of the user, transfers it to a video storage/processing part 104 and writes the received video image in a memory. When data received by a line interface part 113 are video request information, a video request analysis part 106 analyzes a received video request and informs the video storage/processing part 104 of request resolution and a request origin equipment. The video storage/processing part 104 reads the video image from the memory, converts it to the specified resolution and then, transmits it to a request origin communication terminal.

摘要： PURPOSE:To select the relation of directions between a participant and other participant by displaying a small window with a face picture of the other participant displayed therein on a screen of the participant so as to surround a desk virtually through the use of the perspective method in a way of offering the recognition of relation of directions. CONSTITUTION:Four seats 101-104 are virtually prepared, three cameras 105-107 and one handset 108 are provided to each site to form a space surrounding a desk 109. Then a face of an opposite party is displayed on a display screen of the handset 108 and its own face picture is sent by using the fixed video cameras 105-107. The handset 108 consists of integration of a camera, a display device and a direction sensor and when the handset 108 is mounted, the picture of the opposite party is observed and the direction of the face is detected. Then the relation of direction with other participants is selected by varying a face picture in the small window depending on the direction of its own face in this way.

摘要： PURPOSE:To obtain a television telephone system to meet the requirement in cooperative work environment such as office, etc., by projection-converting an image which is image-picked up by means of a camera, sticking it together on photograph positions of an image memory and transmitting and displaying the content of the memory. CONSTITUTION:An object of photograph T1 is photographed. by a movable camera with position sensor 2, and the photographed image V(t) 5 is obtained. The image 5 is the one obtained by photographing a part of an area S3 in the object of photograph T1, and the photographing area S3 is fetched into an image memory space W4 as the image in the number of pixel nXm, At that time, it is decided based on the photograph position which the camera 2 detects into which place of the space W4 the photograph image is fetched, For image-picking up the whole object T1, the camera 2 is moved and a photographing area S is moved, another differente partial area is photographed and the photographed image V(t) which is continuous to time (t) is fetched into memory space W4. Then, it is overwritten on memory space W4 and is sticked to space so as to fetch the image. The image is displayed in a display part.

摘要： PURPOSE:To automatically generate the summary of a video by analyzing a voice reproduced following the reproduction of the video, comparing feature information obtained from an analytic result with the feature information with respect to the voice set in advance, and extracting a scene satisfying a condition from the video. CONSTITUTION:An image scene extraction device 24 performs the analysis of an audio signal, and captures comparatively wide spectrum feature and the audio features of a signal level with steep rise and continuing in a short time as the audio feature with high correlation, for example, when a shout of joy arise. And it is compared with the conditions set at those features, and when it satisfies the condition, the recording of a video signal and the audio signal are performed on a video tape recorder 25. By repeating such operation, the string of highlight scenes when the shout of joy arises is recorded on the video tape recorder 25. After a program is completed, a user can observe the highlight scene in a short time by rewinding and reproducing the video tape recorder 25.

摘要： PURPOSE:To transmit a picture with high picture quality at a low bit rate while the size of a code book is decreased by using two kinds of sizes of the block being split inputted picture dependingon the quantity of distortion in matching with the code book. CONSTITUTION:A predetermined threshold value xT is compared with a minimum distortion Min di obtained at a minimum selector 19 by a threshold comparator 21. When the value di is small, The 1-bit representing a 4 X 4 block is added to a block number (i) stored in a code book address latch 20 by a block size information adder 22 and the result is sent as a coded output. When the distortion Min di is larger than the threshold value xT, the block in the input block data 13 is split into 4 sets of 2 X 2 blocks by a block 4-split device 23, a block closest to individual 2 X 2 blocks is selected from the 2 X 2 code block 24 the same as the case with the 4 X 4 block and the information representing the 2 X 2 block is added to the number of the blocks by a block side information adder 22 and the result is sent.

摘要： PURPOSE:To make it possible to improve the quality of a picture especially in a small number of picture elements on the scope by correcting the picture with providing a dotted grid having the same number of the picture element with the number the picture element of the picture image on a display scope. CONSTITUTION:A dotted grid 3 that is made to have the same resolution with that of the picture image is printed in advance on a transparent sheet sizing to cover all of the surface of a CRT2 and is sticked on the surface of the CRT2. Or, by generating a pattern by circuits using a pattern generator, the dotted grid 3 is generated on the display plane of the CRT2. Regarding the resolution of the dotted grid 3 generated on the display plane of the CRT2, it has a close relationship between that and that of the scope. When the resolution of the dot coincides with that of the picture image, the highest average opinion evaluation is obtained and even when the resolution of either the dot or the picture image is high, the evaluation is low than in the case when both resolutions are the same. Also, as a parameter for the resolution of the picture image, when the resolution is high, the average opinion evaluation is increased.
