In order to display Bayer input stream received from CMOS image sensor to the display device, image signal processing must be performed. That is, the hardware performing the image signal processing for Bayer data is called ISP(Image Signal Processor). We can see real image through ISP processing. ISP executes functionalities for gamma correction, interpolation, color space conversion, image effect, image scale, AWB, AE and AF. In this paper, we obtained the optimum algorithm through software verification of ISP module for CMOS camera image sensor and described using VHDL and verified in ModelSim6.0a simulator. Also we downloaded into Xilinx XCV-1000e for the designed ISP module and completed the board level verification using PCI interface.

Purpose: This study attempts to find how the cultural marketing activities utilizing cultural space affect firm's brand image and brand loyalty, and whether this culture marketing technique is recognized as a social contribution activity by potential customers and thereby influence brand image and loyalty. Methods: The data was collected by using the structured questionnaires to consumers who have experience using the Naver Library, Starfield Library, and Hyundai Card Library. The proposed research model is tested using 178 valid questionnaires using Smart PLS 2.0. Results: This research indicated that among cultural marketing factors, cultural support and cultural promotion have little impact on brand image, whereas culture firm influence brand image. Brand image also had an impact on brand loyalty, but it was found that public libraries operated by companies were not recognized as corporate social contribution activities, nor did they have an impact on the formation of the company's brand image. Conclusions: The study offered a theoretical and empirical foundation for future research by empirically identifying the relationship between cultural marketing and brand image and loyalty and confirmed the coordinating effect of social contribution activities between a cultural firm and its brand image.

This study is based on the Virtual Reality Space what grow rapidly compared with other space type. We make a certain definite possibilities by the functional, material, scientific and conceptual space comparison approved with existing visual space about the function of sound and visual system & the application of the mechanical system. Symbol and Expression Media are showing characteristics more than a tool in Modern times being changed from materialistic world to immaterial one. Especially, Augmented Reality, which is the new technology showing human beings real world and virtual world simultaneously recently and being exceeded to existent many limits, is going ahead. Simulation space is the technology one which can be applied to various fields such as culture, industry and education etc., and it helps human beings to overcome their limitations. The gains from this study are the specified and detailed yardsticks and cases of Simulation(space) facilities classified as a specific space. Therefore, the space mainly consists of the parts on size, equipment, and material etc. judging from technical point of view. Architectural Space, especially, should be considered very importantly in the middle of the transition from image realization to experience. The comprehension on various contents together with mechanical facilities will be requested to the connection applied to physical space expression, and that is what we have to study continuously afterward.

Arriving in the new space age, securing technology for fusion application of KOMPSAT-3·3A and global satellite images is becoming more important. In general, multi-sensor satellite images have relative geometric errors due to various external factors at the time of acquisition, degrading the quality of the satellite image outputs. Therefore, we propose a fine-image registration methodology to minimize the relative geometric error between KOMPSAT-3·3A and global satellite images. After selecting the overlapping area between the KOMPSAT-3·3A and foreign satellite images, the spatial resolution between the two images is unified. Subsequently, tie-points are extracted using a hybrid matching method in which feature- and area-based matching methods are combined. Then, fine-image registration is performed through iterative registration based on pyramid images. To evaluate the performance and accuracy of the proposed method, we used KOMPSAT-3·3A, Sentinel-2A, and PlanetScope satellite images acquired over Daejeon city, South Korea. As a result, the average RMSE of the accuracy of the proposed method was derived as 1.2 and 3.59 pixels in Sentinel-2A and PlanetScope images, respectively. Consequently, it is considered that fine-image registration between multi-sensor satellite images can be effectively performed using the proposed method.

In this paper, we introduce the implementation of the security system using iris recognition. This system acquires images with infrared camera and extracts the 2D code from a infrared image which uses scale-space filtering and concavity. We examine the system by (i) extract 2D code and (ii) compare the code that stored on the server (iii) mearsure FAR and FRR using pattern matching. Experiment results show that the proposed method is very suitable.

The paper raises a question in argument about the method of creating space depending on accidental creation by computer as the method of describing movement pattern, and emphasizes the role of the mathematics which may change the shape into the image or reflection, that is, data which human may understand and expect. If the mathematics could be the method of describing movement pattern, it may play a important role on the analysis of architectural space based on the idea of post-constructionism, which is likely to consider the modern architectural space recognized as the sequential frames containing movement, as the suspended state of the moving object. And then, this infinite series, 'the sum' of the suspended state, is not studied mathematically and scientifically, but is able to be shaped by reviewing the validity in mathematics about the nonlinear space. This is, therefore, the fundamental research in order to define the role of the mathematics in formation of space of contemporary architecture.

Language is the method for communication. Semantician, G. Leech categorized the function of language as informational, expressive, directive, aesthetic and phatic one. Therefore, language can be defined as the social symbol system and the media for communication. Space, also, performs the role of symbol, information and communication. Space can be the media for the communication and the design can be logical construction process by it's arbitrary interpretation. The researcher considered the common points between verbal language and visual language as the tools for the mutual communication, tried to transit them into the 'space' as object language after analyzing 'image of poetry' as meta language, so that the old perspective of space design as function can be renewed as information system of the significant meaning delivery in the context of language's multiplicity, expandibility and changeability.

The historic cultural landscape of East lake in Kyung river area during Joseon dynasty was very outstanding that it had many attractions of scenic beauty, however, the Han river of today is being recognized as a natural landscape and as a place with low cultural and historical traits. This study applied landscape characteristics of the cultural space of Joseon Dynasty on visual image elements of Lynch to research the landscape characteristics. The research results are as follows. When East lake was applied to visual image elements, it was recognized as a 'superb' 'paths,' and the 'edge' which signifies the boundary showed its 'superb' clarity of the East lake. For the 'node,' a turning point of direction, Dumopo represented the 'superb' awareness. As East lake, Apgujung, and Jecheonjung represented the 'superb' awareness when 'landmark' among visual image elements of Lynch was applied to the cultural space, the awareness level and reputation were proportional to the visual image elements. When pattern, structure, and meaning of the cultural space were clear and had definite identity, the 'landmark' and 'district' elements were 'superb.' It was also identified that when awareness level of space was higher, the awareness of historic cultural landscape was high as well. Therefore, considering visual awareness level of the historic cultural landscape of Han river during restoration to investigate and to conduct case studies is considered to increase the awareness level of historicity and cultural character as well as restoration of the place.
