At this time, digital cameras are used in art and forensic science. However, the digital camera has some limitations which need to understand of photograph and lighting. It is a useful paper to make an infrared flatbed scanner. The following processes offer an infrared flatbed scanner development. First, the infrared flatbed scanner changes visible fluorescent lamp to infrared LED. Second, it equips a long-pass filter, which is available to pass over 810nm wavelength, on the glass to complete the optimal infrared flatbed scanner. In addition, it must copy from digital camera to computer directly. The infrared digital camera has disadvantage to always irradiate infrared lamp. Because of difference between visible length and infrared length characteristic, they have different focal distance. This devised scanner for solving mentioned problems does not need to irradiate infrared lamp, and there is not a problem about focal point because the depth of field of flatbed scanner is minimum 2mm. Lastly, the infrared flatbed scanner can make high resolution which is 12,800dpi unlike digital camera. Accordingly, the infrared scanner looks forward to be used in many field of study.

According to development of the areial photogrammetry, it is uneconomical to acquire the terrain information and compute the earthwork volume of each building site by a field surveying which is used recently because it is acquired much money and time. The aim in the this thesis is to acquire the terrain information using the Digital Terrain Model (DTM) to gain in the aerial photograph and compute the rapid and economical earthwork carrying out digital test. Because of being little difference between the digital test and field (site) surveying in the earthwork volume, that result is fitter in preliminary planning than in practical planning to the extent.

These days, we can't confirm cadastre information about stereoscopic digital map that was consist of 2 dimensions and more difficult to understand of detailed parcel boundary, area, land using for 3 dimensions. An each local government providing three-dimensional that are connected to an aerial photograph with cadastre maps. Satisfaction is high for citizens but, this service additional cost for purchase of an aerial photograph order to provide of it. So far, in various ways are under study about three dimensions using Google Earth which is possible to provides 3 dimensional information by real time for individual parcel situation. The purpose of this study was analyzed an accuracy of overlapping between cadstre maps and an image on Google Earth Web in the each different coordinates system. Also, this paper could be provided for use possibility of 3 dimensions information service with an indicator of using or a guideline of direction for local government which provide 3 dimensions information oneday.

In mid-July, 2006 the torrential rainfall across Gangwon-do region caused 48 casualties and 1,248 houses submerged, resulting in damages with the restoration costs of 3 trillion and 512.5 billion won. This was because the topographic characteristics of Gangwon-do region for which mountainous areas mostly account increased the effects of landslide. In this study, the landslide region was shot using the PKNU No.4 system immediately after the occurrence of landslide in order to analyze it as objectively, exactly, and rapidly as possible. 1,054 areas with landslide occurrence were extracted by digitizing the shot images through visual reading after orthometric correction using ERDAS 9.1. Using the Arc GIS 9.2, a GIS program, hydrologic, topographic, clinical, geologic, pedologic aspects and characteristics of the landslide region were established in database through overlay analysis of digital map, vegetation map, geologic map, and soil map, and the status and characteristics of the occurrence of the landslide were analyzed.

Before the appearance of luc-media image, art is performed by the hands of man. That was the best of the reality and the absolute standard of reality. However the appearance of luc-media image brings together the scientific thoughts on realism, which gave birth to 'impressionism' where 'light' becomes the most important part in art as well as in luc-media image and analyzed scientifically. In this paper, I'd like to analyze 5 paintings of Monet, a representative of the impressionism, chronically and present the various aspects of luc-media image as follows; 'picture the present moment', 'picture the light', 'picture the sound and movement', 'picture in the several frames', 'picture continuous frames'. These image phenomenon presented in this paper are mainly concerned with the photograph image, because the time when impressionists entered the stage was the age of photograph image, accordingly there are a little difference from digital image.

In the history of photograph, after the development of color photographs, those with multiple colors and high definition has gradually become the mainstream works in the field of photography. In the modern society of China that has been through reform and opening up, people's minds were increasingly liberated to widely accept color photos in terms of photography. Furthermore, the broad penetration of digital photography has brought together a new trend in the field of black-and-white photography. In line with this trend, more black-and-white photographs have appeared which are different from existing ones in the film-based period. In this recognition, the study seeks to compare the black-and-white documentary photograph works of Chinese photographers and analyze the modern Chinese black-and-white photographs.

The LiDAR data structure has the potential for modeling in three dimensions because the LiDAR data can represent voxels with z value under certain defined conditions. Therefore, it is possible to classify the physical damaged degree of vegetation by forest fire as using the LiDAR data because the physical loss of canopy height and width by forest fire can be relative to an amount of points reached to the ground through the canopy of damaged forest. On the other hand, biological damage of vegetation by forest fire can be explained using the NDVI (Normalized Difference Vegetation Index) which show vegetation vitality. In this study, we graded the damaged degree of vegetation by forest fire in Yangyang-Gun of South Korea using the LiDAR data for physical grading and digital aerial photograph including Red, Green, Blue and Near Infra-Red bands for biological grading. The LiDAR data was classified into 2 classes, of which one was Serious Physical Damaged (SPD) and the other was Light Physical Damaged (LPD) area. The NDVI was also classified into 2 classes which are Serious Biological Damaged (SBD) and Light Biological Damaged (LBD) area respectively. With each 2 classes ofthe LiDAR data and NDVI, the damaged area by forest fire was graded into 4 degrees like damaged class 1,2,3 and 4 grade. As a result of this study, 1 graded area was the broadest and next was the 3 grade. With this result, we could know that the burned area by forest fire in Yangyang-Gun was damaged rather biologically because the NDVI in 1 and 3 grade appeared low value whereas the LiDAR data in 1 and 3 grade included light physical damage like the LPD.

In this study, we propose an information providing and learning system using augmented reality in the exhibition (museum, performance) environment. In a typical exhibition space, a description of a picture or a photograph is provided in a printed matter or a space in the form of an information space (explanatory space), or an auxiliary explanation using an 'audio guide' or a 'docent' program. Augmented reality technology is applied to the exhibition space in the form of a fusion of these methods, and the description of the exhibition is provided to the user in various forms such as text, picture, audio and image, thereby providing stereoscopic information and learning. We apply the augmented reality technology in a specific exhibition space and utilize it as a tool of providing information and learning using image description of pictures.

As mobile digital devices have come into more widespread use, the demand for mobile storage devices have been increasing rapidly and most of digital cameras and camcorders are using SD memory cards. The SD memory card are generally employing a form of copying data into a personal computer after storing user data based on flash memory. The current paper proposes the SD memory card of being capable of storing photograph and image data through network rather than using a method of storing data in flash memory. By delivering data and memory address values obtained through SD Slave IP to network server without sending them to flash memory, one can store data necessary to be stored in a computer's SD memory in real time in a safe and convenient way.

In this paper, we look photographes of costumes and composed them as image files by extracting only costume part of the photograph excluding the background part. And we calculated representative color value to implement smart costume coordination program using complementary colors corresponding to representative color values in the costume area. And then, We have solved the problem of over-segmentation caused by extracting the costumes area by applying an anisotropic diffusion algorithm that can remove the noise of the image and flatten the gradient. In order to satisfy users' various needs, we plan to add not only complementary colors coordination but also more various color scheme.
