    Abstract: PROBLEM TO BE SOLVED: To provide a communication controller by which users making party communication can easily share a charged file including the utility charge of a communication channel imposed on the party communication in diversified modes. SOLUTION: The communication controller has a party connection control module 104 that transmits data sent by terminals 51-53 via a communication channel 3 to a communication unit other than the terminals sending the data as its control and a user bill monetary amount decision module 103 that calculates a charge imposed on the terminal 51-53 because of use of the communication channel 3 and decides a charge imposed on user 41-43 on the basis of the calculated charge and the charge imposed on the party communication connection service.

    Abstract: PROBLEM TO BE SOLVED: To obtain a video image pickup device that can easily inspect detection of a defect in a short time and to obtain inspection device therefor and its inspection method. SOLUTION: An evaluation picture 2 is generated by quantizing reference picture data in a 2nd quantization step number less than a 1st quantization step number of a digital signal processed in a video photographing device 1 in a usual photographing. A quantizer in the video photographing device 1 quantizes a digital signal obtained by photographing the evaluation picture 2 through a solid-state image pickup element in a 3rd quantization step number less than the 1st quantization step number to generate evaluation picture measurement data. The data are compared with the reference picture data to inspect the video photographing device 1.

    Abstract: PROBLEM TO BE SOLVED: To simplify circuit configuration and to lighten processing to be performed by a control part. SOLUTION: An external host 11 writes Q matrix data into a register 5. A control part 6 reads the Q matrix data written in the register 5 and writes them into a Q matrix storage part 31. While using the Q matrix data stored in the Q matrix storage part 31, a discrete cosine transform(DCT)/Q processing part 2 quantizes image data outputted from a ME/MC processing part 1 and outputs them to a variable length code (VLC) processing part 3. While using the Q matrix data stored in the Q matrix storage part 31, the VLC processing part 3 applies VLC processing to the inputted data and outputs them to an interface 4 as well.

    Abstract: PROBLEM TO BE SOLVED: To reduce the storage capacity of a memory provided in the compression coding/decoding device in an image information transmission system in compliance with the Motion Picture Experts Group(MPEG) or the Joint Photograph Experts Group(JPEG) or the like. SOLUTION: In an encoder 1 as a compression coder applying compression coding to a received image signal in compliance with the standards such as the MPEG, other compression/expansion is conducted by using a signal compression circuit 11 and a signal expansion circuit 12 than the main compression coding which is conducted by using a motion detection/compensation processing circuit 9, a discrete cosine transformation/quantization circuit 4, a Huffman coding circuit 5. Thus, the storage capacity of the memory 2 is reduced by reducing the information quantity to be written in a memory 2 provided to the compression coder. Moreover, the storage capacity of the memory 2 provided to the decoder by applying other compression/expansion to the decoder in compliance with the MPEG or the like other than the decoding processing corresponding to the compression coding is reduced.

    Abstract: PURPOSE: To reduce circuit scale in the case of simultaneously detecting a frame motion vector and a field motion vector. CONSTITUTION: A reference frame block is supplied from a memory 20 to a feature extracting circuit 21A, and a retrieval frame block is supplied from a memory 30 to a feature extracting circuit 31A. At the extracting circuits 21A and 31A, matching elements for frame are provided by dividing the frame block into small blocks and integrating picture elements constituting the respective small blocks. The frame motion vector is provided by performing matching processing while using the matching elements provided from the extracting circuits 21A and 31A. The odd-numbered field motion vector and the even- numbered field motion vector are provided by performing matching processing while using a matching element for odd-numbered field and a matching element for even-numbered field which are provided by dividing the matching elements provided from the extracting A feature extracting circuit for providing the matching elements for field is not required.
