摘要： PURPOSE:To enable also a person having no expert knowledge to easily con struct ecometric model by automatically preparing a model expression expressing mutual relation between economical indicator data. CONSTITUTION:A relational expression (model expression) between plural economical indicator data is prepared by a pattern retrieving device 1011, a statistic analyzer 1012 and an automatic model expression preparing device 1013. A topic influence analyzer 1014 prepares a model expression expressing relation between economical index data and topic information. Then an externally generated variable scenario automatic preparation device 1031 automatically prepares an externally generated variable scenario. A qualitative data scenario preparing device 1032 prepares a qualitative data scenario. Then which is to be executed, normal mode simulation or test mode simulation, is judged. Whether a forecasted result in each mode is proper or not is judged, and when the result is proper, the forecasted result is stored in a forecasted result storing device 1100.

摘要： PROBLEM TO BE SOLVED: To easily create an image of a wide field of view and high precision by a multi-camera arranged at different focuses.
SOLUTION: A multi-camera 101 to 108 are arranged so that the imaging regions 109 to 116 include a region of a virtual screen 117 assumed on a photographing object, and have a duplication part. Each focus between the multi-cameras 101 to 108 and the virtual screen 117, is arbitrary for each camera. Correction data for combining the multi-camera 101 to 108 on the virtual screen 117 are created by an arithmetic unit 128 from images photographed by the multi-cameras 101 to 108, and the correction data are set in an image processing device 126. By this method, the image processing device 126 reproduces a correction image of a wide field of view.

摘要： PROBLEM TO BE SOLVED: To obtain a calculation method for quickly calculating value at risk and an earning at risk by calculating the value at risk and the earning at risk, based on the detailed information of a certain item and an item rate scenario. SOLUTION: A market DB preparation program realized a date (here-after referred to as an interest changing date) for reconsidering interest in the future based on the information of a details DB and applies interest, corresponding to an interest changing date in an item interest rate scenario DB. Then market data are prepared and stored in a market DB. A VAR/EAR calculation program calculates the current price or the like, before the change of an interest scenario from the information of the market DB and the information of the interest scenario and stores the calculated result in a simulation result DB. Since the value at risk and an earning at risk calculated by this Monte Carlo simulation are highly efficient, processing speed can be improved, while the accuracy of calculation is maintained.
