소득수준이 향상됨에 따라 소비자의 예술에 대한 관심이 커지고 있으며, 이러한 추세를 반영하듯 아트마케팅이 대중화되고 있다. 본 연구는 예술작품을 활용한 광고 형식을 유형화 한 후 명화의 시장 노출 빈도에 따른 소비자들의 광고 효과(광고태도/회상/진단성)를 실험연구를 통해 살펴보았다. 본 연구결과, 첫째, 명화 활용 방식에 따른 회상은 통계적으로 유의미한 차이가 발생하지 않았다. 그러나 재해석된 명화에 대한 진단성은 긍정적인 것으로 나타났다. 둘째, 시장노출빈도가 적은 명화광고가 상대적으로 더 많이 회상된 것으로 나타났다. 셋째, 시장 노출빈도가 높은 명화를 재해석한 광고가 가장 회상이 높게 나타났다. 본 연구는 고관여 제품에 한정하였으나 향후 저관여 제품에 대한 연구도 진행해 볼 필요가 있다. 본 결과는 효과적인 명화차용 광고를 제작하는데 기여할 것으로 기대된다.

Sexual behavior and reproductivity of male fIsh were studied as an in vivo screening method of endocrine disruptors. Male medaka (Oryzias latipes) were exposed to 17$\beta$-estradiol at nominal concentrations of 2 and 20 $\mu\textrm{g}$/l for 14 days. After exposure of the chemical, sexual behavior between male medaka and normal female which were injected with prostaglandin $F_{2\alpha}$ just before the test, was analysed by using video camera for one hour. Normal control male showed courtship dancing such as following, guarding, dancing and crossing while 17$\beta$-estradiol treated male did not show any type oj courtship dancing. Furthermore, fecundity and fertility were significantly decreased in the treated group. It was suggested that analysis of sexual behavior could be a useful endpoint for the screening of the endocrine disruptors.

This letter proposes a real-time digital image stabilization system for cell phone cameras without the need for frame memory. The system post-processes an image captured with a safe shutter speed using an adaptive denoising filter and a global color correction algorithm. This system can transfer the normal brightness of an image previewed under long exposure to the captured image making it bright and crisp with low noise. It is even possible to take photos in low-light conditions. By not needing frame memory, the approach is feasible for integration into the size-constrained image sensors of cell phone cameras.

The experimental model of the 8-view stereoscopic display system using the photopolymer-based VHOE is proposed. At first, the VHOE is implemented by angle-multiplexed recording of 8-view's diffraction gratings using the optimized exposure-time scheduling scheme in the photopolymer (HRF-150-100) and then. the VHOE-based 8-view stereoscopic display system is implemented by sequentially synchronizing the incident angles of the reference beam of the VHOE with the 8-view stereo images on the LCD pannel. Accordingly, from some experimental results using 8-view images generated by the toed-in stereo camera system, it is found that 8-view stereo images can be diffracted to eight different directions time-sequentially and there is some disparity between the stereo images.

현재의 비디오 카메라는 인간의 눈으로 볼 수 있는 것과 동일한 화질의 비디오 영상을 얻을 수 없다. 인간의 눈은 움직이는 물체에 중점을 두고 초점을 맞추는 시각적 특성을 가진다. 하지만 현재의 비디오 카메라 시스템은 영상에 대한 인간의 눈의 시각적 특성에 대한 고려 없이 조리개와 렌즈의 조절 작업이 이루어진다. 본 논문은 이러한 비디오 카메라 시스템의 개선을 위해 인간의 눈의 시각적 특성에 기반을 둔 실시간 피사체 적응 비디오 카메라 시스템을 제안한다. 제안하는 알고리즘은 영상내에서 움직임을 가진 물체를 찾아낸 뒤, 이것에 가중치를 두고 조리개와 초점제어 작업의 순서로 이루어진다. 움직이는 물체는 영상 코덱의 움직임 정보를 파악하여 찾아내었다. 제안된 알고리즘은 프로그램언어로 구현되었으며, 초점거리와 조리개제어가 가능한 카메라와 PC를 사용하여 영상을 분석, 검증하였다.

This paper presents a design of the real-time preprocessor for CMOS image sensor suitable to the digital camera applications. CMOS image sensor offers some advantages in on-chip integration, system power reduction, and low cost. However, it has a lower-quality image than CCDs. We describe an image enhancement algorithm, which includes color interpolation, color correction, gamma correction, sharpening, and automatic exposure control, to compensate for this disadvantage, and present its efficient hardware architecture to implement on the real-time processor. The presented real-time preprocessor was designed using VHDL, and it contains about 19.2K logic gates. We also implement our system on FPGA chips in order to provide the real-time adjustment and it was successfully tested.

This paper presents the measurement and correction of PCB alignment errors for PCB-manufacturing machines. The conventional PCB-manufacturing machine doesn't have enough accuracy to accommodate the demand for high-resolution circuit pattern and high-density mounting capacity of electronic chips. It is because of alignment errors of PCB loaded to the PCB-manufacturing machine. Therefore, this study focuses on the development of the system which is able to measure and correct alignment errors whit high-accuracy. An automatic optical inspection part measures the PCB alignment error using two cameras, and the high-accuracy 3-axis stage makes correct of these error. The operating system is run in the environment of Window 98 (or NT). Finally we implemented this system to PCB screen printer and PCB exposure system.

The demand for human security significantly promotes the development of surveillance applications using a multi-sensor integrated UAV system. For more sophisticated operations, the system should provide a sequence of images rectified in a ground coordinate system in realtime. This rectification requires accurate position and attitude of the camera at the time of exposure of each image, which can be estimated through an Aerial Triangulation process using the GPS/INS data and tie points between adjacent images. In this work, the KLT tracker is utilized to obtain the tie points. To satisfy the realtime requirements, we present an approach to speed up the tracker by supplying the initial guessed positions of tie points based on the exterior orientation. The experimental results show that, when the guessed positions are supplied, the KLT tracker consumed less computational time than the ordinary KLT which is more suitable to be incorporated into the realtime image georeferencing process.

With the spread of various kinds of cameras such as digital cameras and DSLR and a growing interest in high-definition and high-resolution images, a method that synthesizes multiple images is being studied among various methods. High Dynamic Range (HDR) images store light exposure with even wider range of number than normal digital images. Therefore, it can store the intensity of light inherent in specific scenes expressed by light sources in real life quite accurately. This study suggests feature points synthesis algorithm to improve the performance of HDR panorama recognition method (algorithm) at recognition and coordination level through classifying the feature points for image recognition using more than one multi frames.

Conventional ultraviolets A,B,C are known to be very important factor of killing, changing surface properties of biological cells and materials. It is of great importance to investigate the influence of extreme ultraviolet (EUV) exposure on the biological cell. Here we have studied high density EUV plasma and its emission characteristics, which have been generated by plasma focus device with hypercycloidal pinch (HCP) electrode under various Ar gas pressures ranged from 30~500 mTorr in this experiment. We have also measured the plasma characteristics generated from the HCP plasma focus device such as electron temperature by the Boltzman plot, plasma density by the Stark broading method, discharge images by open-shuttered pin hole camera, and EUV emission signals by using the photodiode AXUV-100 Zr/C.
