In this paper, we propose a computational generation method of elemental images for time-multiplexed 3D integral imaging display based lens division. In the proposed method, we analyze the image formation between 3D object and elemental images based on ray optics. Based on the analyzed formation, we generate the elemental image set for time-multiplexed display. Positions of an object point picked up in proposed method is shifted for half size of lens divided from those in conventional method when generating elemental images. To show the usefulness of the proposed method, we carry out the preliminary experiments and present the results. 본 논문에서는 렌즈분할 기반의 시간다중화 3D 집적영상 디스플레이를 위한 컴퓨터적인 요소영상 생성 방법을 제안한다. 제안하는 방법에 대하여 3차원 물체와 요소영상 사이의 기하광학적인 결상관계를 해석하고, 이 결상관계를 통하여 시간다중화 방식의 요소영상들을 생성한다. 요소영상 생성할 때, 제안하는 방법에서는 픽업되는 물체점의 위치가 기존 방식의 위치보다 절반의 분할렌즈 크기만큼 이동된다. 제안한 방법에 대한 기초적인 실험을 수행하고 그 결과를 보고한다.

One of the recent Chinese tendency is to bring the old thoughts back to their senses. This study focuses on inquiry into the economic consciousness from the traditional Chinese mythological stories and the economic thoughts from five major Chinese philosophers and literary scholars as the origins of the Chinese economic mind. The Chinese economic mind regarding commerce as important has been firmly preserved since the mythological age. So, the Chinese commerce progressed enough to open the Silk Road as early as in the third century B.C. And many wealthy merchants appeared in spite of the agriculture-first and commerce-last policy based on the "four classes thought" advocating an inequal jobs in order of scholars, farmers, artisans, and merchants oriented by the Legalist and the Confucian scholars, After all, such a thought was substituted for a "new four classes thought" of equal jobs, and now the four classes thought is not clear in the Chinese economic mind. The Korean economic mind seems to be similar to the Chinese because of their similar cultural histories and thoughts. But both are quite different in many aspects. For example, the Korean commercial consciousness has not so enough strong as the Chinese to overcome the traditional "four classes thought" and the agriculture-first and commerce-last policy oriented by the doctrines of Chu-tzu through the Choson dynasty era. Thus the tradition of the "four classes thought" is still remained in the Korean economic mind.

For leading a financial Big Bang in the capital market by stimulating financial innovation and competition, the Korean government is working on the establishment of Capital Market and Financial Investment Services Act which will consolidate the existing capital market related acts. One of the main points of this act is to regard financial products with possibilities of losing a part of the principal as ``financial investment products``. Another main point is that a financial investment company is allowed to manage all six financial investment businesses(investment transactions, investment intermediation, collective investments, investment commitments, investment consulting and trust businesses). Also the Act extends the scope of investment business. For example, the Act allows financial investment companies to join the micro-settlement system of Korea Financial Telecommunications & Clearings Institute and this will greatly improve the convenience of the securities account, which until now was bound to provide only basic services. Finally the Act is upgrade the investor protection mechanism. For example, financial investment companies are required to receive clients`` signatures which confirm that clients are well informed of the details of the investment products when they sell investment products. Though the scope of this legislation is yet limited to the capital market and the securities industry, requests will be growing that banking and insurance industries should adopt the same regulation system. On the other hand, the business scope extension in securities industry is likely to causes more competitions among the industries and consumers in banking and insurance industries may claim more strict consumer protections in their areas. Because nowadays many securities companies are belong to financial groups, all the financial companies in a financial group will enjoy synergy effects by turning a securities company into a financial investment company. One of the worries regarding the Act is related with allowing financial investment companies to join the micro-settlement system. In spite of all the carefully designed systemsafety- purposed devices, overall risks of micro-settlement system due to the entrance of the securities companies are estimated to be increased slightly. For the banking industry, this legislation will be the chance to diversify banks`` income structures and increase their customers. However, the trust business in bank can be shrunken as the financial investment companies can run the trust business as a main business. For the insurance industry, the Act will help to improve the asset managing environment and escalate the possibility of joining the micro-settlement system, but competitions will also be growing because some business area can be overlapped. Clearly the securities industry will enjoy many benefits from the Act. First of all, the role and scale of the capital market will be enlarged and capital market related financial institutions can be large enough to compete with international investment banks such as Merrill Lynch through the capital increase and M&As. Competitiveness of investment products will grow and business grounds for the financial investment companies will be strengthened by offering comprehensive financial services. However, there is a good possibility that foreign investment companies can erode the new profitable market with advanced financial technique, skilled experts and sufficient capitals. For minimizing the adverse effects and maximizing the positive effects, the methods of financial supervision should be adjusted. The confusion caused from the co-existence of institutional regulations(banking and insurance industry sectors) and functional regulations (securities industry sector) can be eliminated by changing the supervisory organization in the way that institutional regulations are supplemented by functional regulations. Also the balances between the securities industry supervision and banking/insurance supervision should be considered to get rid of possible discriminations caused by different regulation systems.
