This thesis proposed a method that connecting step motor to image send board which can acquire image to move and remote controlling via streaming image board of PDA(personal digital assistant) based on embedded Linux which is using wireless network There are three embedded Linux system to embody movable image send board. First, though the wireless network a signal of PDA is transmitted to the board which has embedded Linux and a system which is controlled by the expansion I/O port of the board. Second, it's a system streaming realtime image at a PDA which has embedded Linux. The last is a system which controls a process of image board using TCP/IP communication and image send board at PC. These are the system which can use industrial settings and homes. It can also make use of an embodiment method about travelling image robot.

Nowadays image processing is very useful for some field of traffic applications. The one reason is we can construct the system in a low price, the other is the improvement of hardware processing power, it can be more fast to processing the data. In this study, I propose the traffic monitoring system that implement on the embedded system environment. The whole system consists of two main part, one is host controller board, the other is image processing board. The part of host controller board take charge of control the total system, interface of external environment. and OSD(On screen display). The part of image processing board takes charge of image input and output using video encoder and decoder, image classification and memory control of using FPGA, control of mouse signal. And finally, fer stable operation of host controller board, uC/OS-II operating system is ported on the board.

This paper represents the design of a real-time image preprocessing system. The preprocessing system performs hardware-wise mask operations and thresholding operations at the speed of camera output single rate. The preprocessing system consists of the preprocessing board and the main processing board. The preprocessing board includes preprocessing unit that includes a $5\times5$ mask processor and LUT, and can perform mask and threshold operations in real-time. To achieve high-resolution image input data($20485\timesn$), the preprocessing board has a linescan camera interface. The main processing board includes the image processor unit and main processor unit. The image processor unit is equipped with TI's TMS320C32 DSP and can perform image processing algorithms at high speed. The main processor unit controls the operation of total system. The proposed system is faster than the conventional CPU based system.

According as the drivers increase who have their cars, the comprehensive studies on the automobile for the traffic safety have been raised as the important problems. Visual Recognition System for radio-controled driving is a part of the sensor processor of Unmanned Autonomous Vehicle System. When a driver drives his car on an unknown highway or general road, it produces a model from the successively inputted road traffic information. The suggested Recognition System of the Road Traffic Safety Information Board is to recognize and distinguish automatically a Road Traffic Safety Information Board as one of road traffic information. The whole processes of Recognition System of the Road Traffic Safety Information Board suggested in this study are as follows. We took the photographs of Road Traffic Safety Information Board with a digital camera in order to get an image and normalize bitmap image file with a size of $200{\times}200$ byte with Photo Shop 5.0. The existing True Color is made up the color data of sixteen million kinds. We changed it with 256 Color, because it has large capacity, and spend much time on calculating. We have practiced works of 30 times with erosion and dilation algorithm to remove unnecessary images. We drawing out original image with the Region Splitting Technique as a kind of segmentation. We made three kinds of grouping(Attention Information Board, Prohibit Information Board, and Introduction Information Board) by RYB( Red, Yellow, Blue) color segmentation. We minimized the image size of board, direction, and the influence of rounding. We also minimized the Influence according to position. and the brightness of light and darkness with Eigen Vector and Eigen Value. The data sampling this feature value appeared after building the learning Code Book Database. The suggested Recognition System of the Road Traffic Safety Information Board firstly distinguished three kinds of groups in the database of learning Code Book, and suggested in order to recognize after comparing and judging the board want to recognize within the same group with Nearest Neighborhood Decision Making.

In this study, the basic image-board and algorithm has been developed to extract a road lane by modeling the driving process. The high speed processing enables an image capture, processing and prompt decision making. In order to high speed processing ASIC like FPGA was designed and integrated in one board system. The algorithm enabling road driving must recognize a straight and bend edge separately. The high speed image processing board using FPGA can be used in real-time decision makeing system for road driving and in the machine vision under bad working environments like a coal mine. And it also can be used in the safety control system in subway and in image input system of CCTV and CATV by designing the board to meet various user's needs.

Recently the development of medical modality like as MRI, 3D US, DR etc is very active. Therefore it is more required not only the enhancement of quality in medical service but the improvement of medical system based on quantization, minimization, and optimization of high speed. Especially, as the changing into the digital modality system, it gets to start using ASIC(Application Specific Integrated Circuit) to realize one board system. It requires the implementation of hardware debugging and effective speedy algorithm with more speed and accuracy in order to support and replace existing device. If objected image could be linked to high speed process board with special interface and pre-processed using FPGA, it can be used in real time image processing and protocol of HIS(Hospital Information System). This study can support the basic circuit design of medical image board which is able to realize image processing basically using digitalized medical image, and to interface between existing device and image board containing image processing algorithm.

교통 분야에서도 역시 영상을 이용한 시스템의 개발이 주요 이슈가 되고 있다. 이는 영상을 이용한 시스템의 경우 설치비용이 기존 시스템들에 비해 엄청나게 저렴하다는 것과 설치하는 기간 중에도 교통의 흐름을 거의 방해하지 않고 설치가 가능하다는 장점을 가지고 있기 때문이다. 본 연구에서는 임베디드 시스템 환경에서 영상 검지기 시스템의 구현을 제안하였다. 전체 시스템은 호스트 컨트롤러 보드부분과 영상처리 보드 부분으로 나뉜다. 호스트 컨트롤러 보드 부분은 전체 시스템의 제어와 외부와의 인터페이스, 그리고 OSD(On Screen Display) 부분을 담당하게 된다. 영상처리 보드 부분은 알고리즘의 적용, 마우스 신호의 베어를 담당하고 있다 그리고 안정적인 호스트 컨트롤러의 보드의 운영을 위해 uC/OS-II 를 호스트 컨트롤러 보드에 포팅하였다.

This study is concerned with image information management system for small scale hospital. We intended to developing image management system which is used of the existing analog devices such as medical camera, supersonic analyser, endoscope etc. We developed a video in interface board based USB 2.0 for handling image in real time. It is capable of transmitting image input signal like as NTSC, PAL to personal computer through USB 2.0. The developed the board of 40 speeds compared with the exiting system based USB 1.0. Especially the developed system is very helpful for small hospital like as dental clinic, because it is easy and convenient to manage image information without expert. So it will provide reduction of time and cost for handling image information(collecting, saving, retrieval, transmitting image).

적외선 영상 시스템으로 야외에서 다양한 영상에 대하여 테스트를 할 때 테스트 한 영상을 저장하여 비교확인이 필요하다. 야외에서 시험을 하기 때문에 휴대성이 간편해야 하며 장시간의 영상을 저장하여야 하기 때문에 많은 저장공간이 필요로 한다. 또한 시험 이후에 쉽게 PC와 접속하여 저장된 데이터를 다운로드 받을 수 있어야 한다. 최근 메모리 시스템의 발전으로 쉽게 On Board 형태로 사용할 수 있는 eMMC 메모리를 활용하여 야외시험용 적외선 영상 저장보드를 설계할 수 있다. 본 논문에서는 적외선 영상을 쉽게 저장하고 다운받을 수 있는 휴대가 간편한 영상 저장보드 설계에 대하여 설명하고 PC와 접속하여 저장된 영상을 다운 받을 수 있는 GUI 프로그램에 대하여 설명한다.
