An image restoration problem with Poisson noise arises in many applications of medical imaging, astronomy, and microscopy. To overcome ill-posedness, Total Variation (TV) model is commonly used owing to edge preserving property. Since staircase artifacts are observed in restored smooth regions, higher-order TV regularization is introduced. However, sharpness of edges in the image is also attenuated. To compromise benefits of TV and higher-order TV, the weighted sum of the non-convex TV and non-convex higher order TV is used as a regularizer in the proposed variational model. The proposed model is non-convex and non-smooth, and so it is very challenging to solve the model. We propose an iterative reweighted algorithm with the proximal linearized alternating direction method of multipliers to solve the proposed model and study convergence properties of the algorithm.

본 연구에서는 자동차 TV광고에서 나타나는 섹슈얼리티의 의미화를 영상기호학적 시각에서 연구하는데 그 목표가 있다. 이를 위해서 페미니즘적 비평을 소개하고, '아네트 쿤(Annette Kuhn)'이 제시한 섹슈얼리티 표현의 구조를 파악하였다. 연구는 국내 자동차TV광고 자료 188편을 대상으로 하였다. 이 중 아네트 쿤의 섹슈얼리티 구조적 특징을 가지고 있는 45편의 광고를 선정하였고, 분석한 결과는 각 구조별로 체계적으로 제시하였다. TV광고의 섹슈얼리티 영상기호 분석이 갖는 의미는 다음과 같이 정리될 수 있다. 대중의 시선을 확보하기 위해 성적표현의 비중이 점차 높아지고 있는 상황에서 다분히 주관적 일수 있는 섹슈얼리티를 기호학에 근거를 두고 설명한 아네트 쿤의 연구로 구조화하여 분석함으로써 어느 정도 객관적으로 구체화 할 수 있었다. 또한, 섹슈얼리티와 자동차가 갖는 독특한 관계를 이해한다면 자동차디자인의 기획 단계에서 컨셉 설정에 따른 구체적인 자료로 활용할 수 있을 것이다. 마지막으로 섹슈얼리티 영상기호의 분석은 TV광고의 제작뿐만 아니라 섹슈얼리티를 표현하고자 하는 다른 여러 영상 제작 과정에 있어서도 실제적인 도움을 줄 수 있겠다.

Korean movies and TV shows have been widely distributed in the international market and have played an important role in shaping the national image of Korea. In this paper, we found that the factors of "actor's image" and "background music and images" among the popular factors of Korean dramas have a positive influence on shaping the national image of Korea through questionnaires and spss tools. At the same time, the study also hopes to analyze the reasons for the success of Korean film and television productions to explore their useful value for the international communication of Chinese film and television productions.

In this paper we propose efficient design and implementation of JPEG image display board that can display JPEG image on TV. we used NAND Flash Memory to save the compressed JPEG bit stream and video encoder to display the decoded JPEG mage on TV. Also we convert YCbCr to RGB to super impose character on JPEG image. The designed B/D is implemented using FPGA.

This study investigated how Korean drama viewing of chinese people influence their formation of Korea's national image as well as their satisfaction through consumption of Korean products. The direct effect and indirect effect of Korean drama viewing on Korea's national image were focused. The survey data on 105 Chinese citizens in Shanghai was put into the analysis. The study found that 1) Korean drama viewing has a positive effect on consumption satisfaction of korean products; 2) Korean drama viewing does not have any direct effect on Korea's national image; 3) the consumption satisfaction of korean products has an positive effect on Korea's national image; 4) Korean drama viewing has an indirect positive effect on Korea's national image, mediated by consumption satisfaction of Korean products. Theoretical and practical implication were discussed.

In this paper, detection algorithm of face region based on skin color of in the TV images is proposed. In the first, reference image is set to the sampled skin color, and then the extracted of face region is candidated using the Euclidean distance between the pixels of TV image. The eye image is detected by using the mean value and standard deviation of the component forming color difference between Y and C through the conversion of RGB color into CMY color model. Detecting the lips image is calculated by utilizing Q component through the conversion of RGB color model into YIQ color space. The detection of the face region is extracted using basis of knowledge by doing logical calculation of the eye image and lips image. To testify the proposed method, some experiments are performed using front color image down loaded from TV color image. Experimental results showed that face region can be detected in both case of the irrespective location & size of the human face.

Current paper introduces the additional multimedia module for digital TV. The module is developed for displaying the image captured by digital still camera, camcorder, or PC in the digital TV. For these purpose, the module has the interface circuit for accessing five media type of memory cards. It decodes JPEG, BMP, or TIFF image data saved in the memory card and converts the image data to analog RGB signal. It also supports three types of output image size from HD to WXGA resolution. So the introduced module could be adopted In the most of digital TV.

The purpose of this study is to find an efficient marketing strategy in terms of media channel communications using one specific case study. Results of previous studies have shown that consumers' exposure to TV, newspaper, radio and magazine related to description of corporate image tends to be influential for consumers' product image, which mainly consists of product preference, expertise, and credibility. It means that media strategy should be different, depending on what kinds of image they try to be purposive. In conclusion, we concluded that TV and radio should be the best vehicle for increasing consumers' positive preference rather than those of newspaper and magazine. Newspaper and magazine are also influential in terms of expertise, and newspaper and magazine should be better than TV and radio in terms of credibility. The results of this study should be similar to previous studies in that TV and radio should be more inducing interest, and print media should be more credible than TV and radio.

Free viewpoint TV can provide multi-angle view point images for viewer needs. In the real world, But all angle view point images can not be captured by camera. Only a few any angle view point images are captured by each camera. Group of the captured images is called multi-view image. Therefore free viewpoint TV wants to production of virtual sub angle view point images form captured any angle view point images. Interpolation methods are known of this problem general solution. To product interpolated view point image of correct angle need to depth image of multi-view image. Unfortunately, multi-view video including depth image is necessary to develop a new compression encoding technique for storage and transmission because of a huge amount of data. Layered depth image is an efficient representation method of multi-view video data. This method makes a data structure that is synthesis of multi-view color and depth image. This paper proposed enhanced compression method using layered depth image representation and H.264/AVC video coding technology. In experimental results, confirmed high compression performance and good quality reconstructed image.

Motion-image-quality of LCD-TVs is discussed by dynamic spatial frequency response. Smaller temporal aperture or higher frame rate can improve dynamic response, but an increase of motion velocity easily cancels the improvement. A guideline for deciding the desirable temporal aperture and frame rate of LCD-TVs is described, under the condition that camera and display have the same parameters. Two candidates of the desirable parameter sets will be (240 or 300 Hz, 50 to 100% aperture) and (120Hz, 25 to 50% aperture), from the viewpoint of "limit of acceptance" on motion-imagequality-deterioration for critical picture materials.
