摘要： PROBLEM TO BE SOLVED: To prevent transfer processing of the entire system from being delayed due to a delay in one transfer processing in the network system in which a network adopting the line survival system is used to transfer data requiring real time processing. SOLUTION: A server machine 1 is provided with a request content confirmation means 2 discriminating a content of a read request from a client machine 5, a data transfer control means 3 controlling transfer of data requested by a read request to a network 4. When data on request are moving image data, the request content confirmation means 2 sets a termination period of data transfer processing. When the processing time of transferring data on request from a disk device 15 exceeds a termination period, the data transfer control means 3 interrupts transfer processing and starts transfer processing with respect to other read request.

摘要： PURPOSE: To provide the output of an image whose line width is the same as that of the input image of a multi-color image by deciding the position and the line width as to one line among one line or over and arranging relatively the remaining lines depending on the line width. CONSTITUTION: A line position decision means 106 decides positions x1 ', x2 ' of lines 203, 204 obtained by magnifying/reducing lines 201, 202. That is, the means 106 rounds off, omits or raises to the tenth of fractions x1 ×x-scale and x2 ×x-scale as the x1 ', x2 ', where x-scale is a magnification/reduction rate in the lateral direction. Moreover, line width decision means 107 decides sets of width l1 ', l2 ' of the lines 203, 204 resulting from magnifying/reducing the lines 201, 204. That is, the means 107 rounds off, omits or raises to the tenth of fractions |l1 ×x-scale| and |l2 ×x-scale| as the l1 ', l2 ', where x-scale is a magnification/reduction rate in the lateral direction. As a result, in the case of the l1 =l2 for an input image, the width of the output image has a relation of l1 '=l2 '.

摘要： PURPOSE:To increase the data transfer speed and also to improve the resistance to the faults of buses by detecting the faults through plural transmission lines, stopping the function of a faulty transmission line, and transferring again the data through an available transmission line. CONSTITUTION:When a fault occurs on an H-side bus 5a, the data are transferred to a bus slave 4 from a bus master A1. Then an H-side detecting/ informing means 4b of the slave 4 recognizes a fact that the data are not normally transferred and reports the fault to an H-side fault detecting/processing means 1b of the bus master A1 via an H-side transfer result informing line 5b. Then a bus selector means 1e refers to a bus workable/non-workable information holding means 1f and confirms that the bus 5a is not workable and an L-side bus 5c is workable to start only an L-side bus control means 1c for retransfer of the data that are held due to the bus fault. Thus the means 1c transfers these held data to the slave 4 via the bus 5c.

摘要： PURPOSE:To reduce and display a character image of KANJI(Chinese character), etc., with high picture quality by decreasing the number of close horizontal lines and reducing the image by constitution which uses a table, etc. CONSTITUTION:Images 102 and 103 of an image 101 are inputted by a means which inputs eight dots in four rows and two columns of image data. Then, table means 106 and 107 output one black dot when one-three dots of the four dots are black, no black dot when there is no black dot, and two black dots when the four dots are black. Further, two dots 108 and 109 are outputted for a four-dot input 102. Namely, when there are white and black dots among the four dots, the both are outputted, so the number of the horizontal lines decreases, but they can be discriminated. When the dots are all black, the dots constitute a vertical line and a white dot is mixed unless the four dots are all black, so they can be discriminated. Lastly, two two-dot outputs 108 and 109 as reduction process results are 0Red and the OR output is generated.

摘要： PURPOSE:To extremely accurately sample a video signal by obtaining the synchronization of the video signal and a sampling clock signal and correcting the phase difference between a horizontal synchronizing signal and the video signal when the video signal to be inputted is sampled. CONSTITUTION:While a two-phase sampling clock signal 103 is generated in the internal part, the sampling clock signal 103 is switch-synchronized with a supplied horizontal synchronizing signal 101 as a reference, and further, the phase difference between a video signal 102 and the horizontal synchronizing signal 101 is detected with the synchronized sampling clock signal as the reference, a delay is added either to the horizontal synchronizing signal 101 or to the video signal 102, and the synchronization is executed. Thus, since the three signals, which are the sampling clock signal, the horizontal synchronizing signal, and the video signal, are completely synchronized, the supplied video signal 102 can be sampled accurately without generating any dot omission and dot formation even when the phase difference exists between the video signal 102 and the horizontal synchronizing signal 101, and further, a period is long, in which the video signal 102 is not supplied.

摘要： PURPOSE: To perform the modification processing of modification areas different by sizes by assigning addresses of a storage circuit, where attribute information for individual modification area are stored, to respective modification areas and storing attribute information and reading out attribute information from the storage circuit in a certain relation to a picture signal to give a signal for deciding the modification area. CONSTITUTION: An attribute information conversion part 3 converts attribute information for individual specific picture elements to that for individual modification areas by data in a modification area parameter storage part 1 and sends these converted information to the storage circuit, and addresses from an address generation part 2 and attribute information from the conversion part 3 are inputted to the storage circuit, and attribute information is stored for each modification area. A synthesis circuit 7 reads out attribute information for each modification area stored in the storage circuit synchronously with the picture signal and makes the read attribute information into a signal synthesized with the picture signal or into a synthesis control signal for synthesis of the picture signal and a synthesized signal supplied from another circuit, thus performing the synthesis processing. Thus, the size of a modification area is previously set to perform the modification processing of the modification area of any size.

摘要： PURPOSE:To enable real-time binarization in sufficient consideration of information on colors or gradations by adding processing in character units when a color or gradational video signal is converted into a binary signal. CONSTITUTION:A video signal generating device 11 generates a color or multilevel video image signal 101 and a color/gradation deciding circuit 12 receives it and decides a color or gradation in dot units. Further, a counter 13 receives the signal 101 to count dots and rasters, and an address generating circuit 14 decides a character from the input number of counted dots and sends the address corresponding to the character to a memory 16. Current picture information inputted to the memory 16 is rewritten on a read-modify-write basis and last picture information is sent to a processing method determining circuit 17. A correcting circuit 15 corrects information from the circuit 12. The circuit 17 determines a processing method for the input information and a processing circuit 18 converts the video signal 101 into a binary signal by the determined processing method and outputs the binary signal.
