PURPOSE: A display device, a control method, and a display system are provided to block a power supply process from a first storage unit to a first control unit by controlling the power supply unit of the display device in a second control unit of an upgrading device. CONSTITUTION: An image processing unit (120) processes an image signal. A display unit (130) displays the processed image signal. A connecting unit (140) connects to an upgrading device (200) processing the image signal. When the upgrading device is connected, a first control unit (180) receives the processed image signal from the upgrading device by controlling the connecting unit. A power supply unit (160) is controlled by the connected upgrading device.

본 발명은 디지털 카메라의 자동 초점 조정 방법에 있어서, 상기 디지털 카메라의 포커스 렌즈를 최대 원거리 촬영을 위한 위치로 이동시킨 후, 미리 설정된 간격만큼 이미지 센서 방향으로 이동하며 해당 위치에 따른 에지값을 추출하는 과정과, 상기 추출된 에지값들을 기반으로 미리 설정된 함수의 형태를 예측하고, 상기 예측된 함수의 최대값을 계산하는 과정과, 상기 포커스 렌즈의 현재 위치에서 계산된 미리 설정된 함수의 최대값과 상기 포커스 렌즈의 이전 위치에서 계산된 미리 설정된 함수의 최대값의 차이를 구하는 과정과, 상기 포커스 렌즈의 현재 위치에서 계산된 미리 설정된 함수의 최대값과 상기 포커스 렌즈의 이전 위치에서 계산된 미리 설정된 함수의 최대값의 차이가 미리 설정된 문턱값 이하인 경우, 현재 계산된 미리 설정된 함수의 최대 값 위치로 상기 포커스 렌즈를 이동시키는 과정을 포함함을 특징으로 한다.
Abstract:
PURPOSE: A hybrid infrared ray filter for a digital camera is provided to prevent the degrading of image quality due to the infrared ray transmittance difference caused from the change of an incident angle of incident light. CONSTITUTION: A hybrid infrared ray filter for a digital camera comprises an absorption filter plate(23), a reflective coating layer(21) and an antireflective coating layer(25). The absorption filter plate absorbs infrared ray. The reflective coating layer is formed in one side of the absorption filter plate and reflects infrared ray. The antireflective coating layer is formed on the other side of the absorption filter plate. Visible ray can the antireflective coating layer.
Abstract:
PURPOSE: A camera optical system is provided to maintain high resolution in a process of close range photographing by moving only a part of a lens system not the whole lens system in a close range photographing. CONSTITUTION: A first lens system is opposed to the subject. The first lens system deviates from the optical axis in a distant photographing process. The first lens system is positioned on the optical axis in a close range photographing process. A second lens system(120) is located between the first lens system and an image sensor(140). A camera optical system satisfies the equation of 0.03

PURPOSE: A graphic processing method for embodying 3D graphic and graphic processor using the same are provided, which interpolate alpha data to pixels at interpolator, and prevent aliasing. CONSTITUTION: A converter changes three-dimensional object into two-dimensional polygon(S1210). A virtual setting unit establishes an imaginary polygon in proportion to a converted polygon(S1220). An alpha data setting unit establishes alpha data of pixel as 1, corresponding to a vertex of converted two-dimensional polygon(S1230). The alpha data establishment part establishes alpha data of pixel as 0, corresponding to the vertex of the imaginary polygon(S1240). An interpolation unit interpolates alpha data to pixels(S1250).
Abstract:
A mobile communication terminal and a camera photographing method of the mobile terminal using a conversion lens are provided to enable a user to freely select a photographing mode according to his/her taste or when necessary by performing the shooting for special effects through the conversion lens which is mounted in a camera assembly. A camera assembly(120) is installed at one side of a terminal body(110). A conversion lens(130) is adhered to the front side of the camera assembly. A locking groove(121) is formed in the front of the camera assembly so that the conversion lens can be attached to the camera assembly. The conversion lens comprises a locking hook(131) corresponding to the locking groove.
Abstract:
A camera lens assembly is provided to reduce the size and weight thereof by driving a lens part for securing sufficient light for photographing by an elastic element. In a lens assembly(102), a lens(127) positioned at an outermost position moves forward in the protruding direction from an opening(111), and any one of the lenses disposed between the outermost position and an image sensor(109) moves in the optical axis direction of the image sensor for controlling a focusing distance.
