Abstract: The present invention is an error picture image data correction apparatus that can correct the error picture image data and suppress the image quality deterioration when there are plural error data in the continuous plural pixels and the data around the error picture image data are high frequency signal data. The apparatus comprises a weighted mean value operation part 101, 102 and 103 for calculating weighted mean value of the 2 pixel data having true value, a channel switch circuit 104, an adder 105, 106 and 109, a selector 107 and 108, a clip circuit 110, a control circuit 113 and an output switch circuit 111. When the input signals of the weighted mean value operation part 101, 102 and 103 at time i is described as G(i), R(i) respectively, t represents time width, n>1, n>k≧0, n and k are integers, and error data are G(i), G(i−t), G(i−2t), . . .

Abstract: Information of the flow of contract information and the flow of payment is acquired from the worldwide-known trade finance EDI service in cooperation therewith. Information of the flow of distribution is acquired from the electronic clearance system. Matching processing is conducted for two kinds of information items from the trade finance EDI service and the customs according to common information contained in both information items such as a container number of a cargo liner or an item number of the cargo for improvement of job efficiency of each firm concerning the trade. The information items are resultantly unified by establishing a connection therebetween and is accumulated in a database in no special order. There is implemented a device to collect clearance information from a plurality of customs at the same time.
