An optical fiber 16 for forwarding the light is provided.

엘이디(14)와 광섬유(16)의 사이에는 엘이디(14)에서 조사되는 빛을 모아서 광섬유(16)로 전달하는 렌즈(18)가 구비되어진다. 엘이디(14)의 일측에 디지탈 카메라부(12)에서 생성된 디지탈 영상신호를 사용자의 스위치(20) 조작에 의하여 정지영상을 생성하는 디지탈 신호처리부(22)가 구비되어지고, 이 디지탈 신호처리부(22)에서 처리된 영상신호를 사용자에게 디스플레이하는 표시장치(24)가 구비되어진다. 본체(10)와 유선 및 무선으로 연결되어 디지탈 신호처리부(22)에서 처리된 영상신호를 저장함과 동시에 사용자에게 디스플레이하는 컴퓨터 시스템(26)이 구비되어진다.A lens 18 is provided between the LED 14 and the optical fiber 16 to collect light transmitted from the LED 14 and transmit the collected light to the optical fiber 16. On one side of the LED 14 is provided with a digital signal processor 22 for generating a still image by operating the user's switch 20 of the digital image signal generated by the digital camera unit 12, the digital signal processor ( A display device 24 for displaying the image signal processed in 22 to a user is provided. The computer system 26 is connected to the main body 10 by wire and wirelessly to store the image signal processed by the digital signal processor 22 and display the same to the user.

상기와 같이 구성된 의료용 카메라가 작동되는 상태를 간력하게 설명한다.The state in which the medical camera configured as described above operates is briefly described.

사용자가 의료용 카메라(28)에 전원을 공급하면, 엘이디(14)에서 빛이 조사되고, 이 조사된 빛은 렌즈(18)를 통하여 광섬유(16)로 전달된다. 이때, 전달된 빛은 광섬유(16)를 통하여 디지탈 카메라부(12)의 전방에 위치하는 피사체에 조사된다. 엘이디(14)에서 전달된 빛이 광섬유(16)를 통하여 디지탈 카메라부(12)의 전방에 위치하는 피사체에 조사되면, 디지탈 카메라부(12)는 피사체를 촬영하고, 디지탈 신호처리부(22)는 촬영된 디지탈 영상신호를 사용자의 필요에 따라 정지영상으로 생성한다. 이때, 영상신호는 표시장치(24) 및 컴퓨터시스템(26)에 의하여 사용자에게 디스플레이된다.When the user supplies power to the medical camera 28, light is irradiated from the LED 14, and the irradiated light is transmitted to the optical fiber 16 through the lens 18. At this time, the transmitted light is irradiated to the subject located in front of the digital camera unit 12 through the optical fiber 16. When the light transmitted from the LED 14 is irradiated to the subject located in front of the digital camera unit 12 through the optical fiber 16, the digital camera unit 12 photographs the subject, and the digital signal processor 22 The photographed digital video signal is generated as a still image according to a user's needs. At this time, the video signal is displayed to the user by the display device 24 and the computer system 26.

상기와 같이 구성된 의료용 카메라를 이용하여 환자의 국부를 촬영하여 확인 및 진찰할 수 있었지만, 이러한 의료용 카메라는 엘이디에서 조사되는 빛이 렌즈및 광섬유를 통하여 피사체에 조사됨으로 엘이디에서 조사되는 빛의 세기(밝기)가 감소되는 문제가 있었다. 즉, 엘이디에서 조사되는 빛은 렌즈를 통하여 광섬유로 전달되는데, 이때 빛이 전달되는 과정에서 빛의 세기가 손실(損失)됨으로 피사체로 전달되는 빛의 세기가 감소되는 것이다.Although it was possible to check and examine a patient's local area by using the medical camera configured as described above, such a medical camera has a light intensity (brightness) irradiated from the LED as the light irradiated from the LED is irradiated onto the subject through the lens and the optical fiber. ) Was reduced. That is, the light irradiated from the LED is transmitted to the optical fiber through the lens. In this process, the intensity of light transmitted to the subject is reduced because the intensity of light is lost in the process of transmitting the light.

또한, 엘이디에서 조사되는 빛의 세기가 감소됨에 따라 피사체가 흐리게 촬영됨은 물론 이에 따라 사용자에게 디스플레이되는 영상이 선명하지 못한 문제가 있었다. 또한, 디스플레이되는 영상이 선명하지 못함으로 환자의 국부를 명확하게 확인 및 진찰할 수 없는 문제가 내포되어 있다.In addition, as the intensity of the light emitted from the LED is reduced, the subject is blurred, and thus the image displayed to the user is not clear. In addition, since the displayed image is not clear, there is a problem that the local part of the patient cannot be clearly identified and examined.

이에 본 발명은 상술한 문제점을 감안하여 안출한 것으로, 그 목적은 광섬유와 엘이디를 일체로 구성하여 엘이디에서 조사되는 빛의 세기가 손실되는 것을 방지함은 사용자에게 디스플레이되는 영상의 선명함을 극대화할 수 있으며 동시에 환자의 국부를 명확하게 확인 및 진찰할 수 있는 의료용 카메라를 제공함에 있다.Accordingly, the present invention has been made in view of the above-described problems, and an object thereof is to configure the optical fiber and the LED integrally to prevent the loss of the light intensity emitted from the LED to maximize the clarity of the image displayed to the user. And at the same time to provide a medical camera that can clearly identify and examine the patient's local.

The digital camera unit 32 uses a charge-coupled device (CCD) device or a metal-oxide semiconductor (MOS) device. One side of the digital camera unit 32 is provided with an LED (LED) 34 that illuminates a subject, and the LED 34 transmits the irradiated light to the front of the digital camera unit 32. Fiber 36 is formed integrally.

엘이디(34)의 일측에 디지탈 카메라부(32)에서 생성된 디지탈 영상신호를 사용자의 스위치(38) 조작에 의하여 정지영상을 생성하는 디지탈 신호처리부(40)가 구비되고, 이 디지탈 신호처리부(40)에서 처리된 영상신호를 사용자에게 디스플레이하는 표시장치(42)가 구비된다. 본체(30)와 유선 및 무선으로 연결되어 디지탈 신호처리부(40)에서 처리된 영상신호를 저장함과 동시에 사용자에게 디스플레이하는 컴퓨터 시스템(44)이 구비된다.On one side of the LED 34, a digital signal processor 40 for generating a still image by operating a switch 38 of a digital video signal generated by the digital camera unit 32 is provided, and the digital signal processor 40 A display device 42 for displaying the image signal processed in the user to the user is provided. A computer system 44 which is connected to the main body 30 by wire and wirelessly and stores the image signal processed by the digital signal processor 40 and displays the same to the user is provided.

상기와 같이 구성된 의료용 카메라가 작동되는 상태 및 이에 따른 효과를 설명한다.The state in which the medical camera configured as described above operates and its effects will be described.

사용자가 의료용 카메라(46)에 전원을 공급하면, 엘이디(34)에서 빛이 조사되고, 이 조사된 빛은 광섬유(36)를 통하여 디지탈 카메라부(32)의 전방에 위치하는 피사체에 조사된다. 이때, 엘이디(34)와 광섬유(36)가 일체로 구성되어 있음으로 엘이디(34)에서 조사되는 빛이 손실되지 않는 것이다.When the user supplies power to the medical camera 46, light is radiated from the LED 34, and the irradiated light is irradiated to the subject located in front of the digital camera unit 32 through the optical fiber 36. At this time, since the LED 34 and the optical fiber 36 are integrally formed, the light irradiated from the LED 34 is not lost.

엘이디(34)에서 전달된 빛이 광섬유(36)를 통하여 디지탈 카메라부(32)의 전방에 위치하는 피사체에 조사되면, 디지탈 카메라부(32)는 피사체를 촬영하고, 디지탈 신호처리부(40)는 촬영된 디지탈 영상신호를 사용자의 필요에 따라 정지영상으로 생성한다. 이때, 영상신호는 표시장치(42) 및 컴퓨터시스템(44)에 의하여 사용자에게 디스플레이된다.When the light transmitted from the LED 34 is irradiated to the subject located in front of the digital camera unit 32 through the optical fiber 36, the digital camera unit 32 photographs the subject, and the digital signal processing unit 40 The photographed digital video signal is generated as a still image according to a user's needs. At this time, the video signal is displayed to the user by the display device 42 and the computer system 44.

피사체에 조명을 가하는 엘이디(34)와 조사되는 빛을 디지탈 카메라부(32)의 전방으로 전달하는 광섬유(36)가 일체로 구성되어 있음으로 엘이디(34)에서 조사되는 빛의 세기가 손실되는 것을 방지할 수 있는 것이다.Since the LED 34 illuminating the subject and the optical fiber 36 which transmits the irradiated light to the front of the digital camera unit 32 are integrally formed, the intensity of the light irradiated from the LED 34 is lost. It can be prevented.

또한, 엘이디(34)에서 조사되는 빛의 세기가 그대로 피사체로 조사됨으로 사용자에게 디스플레이되는 영상의 선명함을 극대화 할 수 있는 것이다.In addition, the intensity of light emitted from the LED 34 is irradiated to the subject as it is to maximize the sharpness of the image displayed to the user.

또한, 사용자에게 디스플레이되는 영상의 선명함이 극대화 됨으로 환자의 국부를 명확하게 확인 및 진찰할 수 있는 것이다.In addition, since the sharpness of the image displayed to the user is maximized, it is possible to clearly identify and examine the local part of the patient.

상술한 바와 같이 본 발명에 따른 의료용 카메라는 엘이디와 광섬유가 일체로 구성되어 있음으로 엘이디에서 조사되는 빛의 세기가 손실되는 것을 방지할 수 있음은 물론 엘이디에서 조사되는 빛의 세기가 그대로 피사체로 조사됨으로 사용자에게 디스플레이되는 영상의 선명함을 극대화 할 수 있으며 동시에 환자의 국부를 명확하게 확인 및 진찰할 수 있는 효과를 갖는 것이다.As described above, the medical camera according to the present invention can prevent the loss of light intensity irradiated from the LED because the LED and the optical fiber are integrally formed, and of course, the light intensity irradiated from the LED is irradiated to the subject as it is. By maximizing the vividness of the image displayed to the user and at the same time has the effect of clearly confirming and examining the local part of the patient.
