摘要： Disclosed is a method for auto-focus control of a digital camera, the method including moving a focus lens of the digital camera to a position for a longest-distance photographing, and then extracting an edge value according to a corresponding position while moving the focus lens by a preset interval in a direction toward an image sensor; estimating a form of a preset function based on the extracted edge values, and calculating a maximum value of the estimated function; calculating a difference between a maximum value of the preset function calculated at a first current position of the focus lens and a maximum value of the preset function calculated at a previous position of the focus lens; and moving the focus lens to a position corresponding to a currently-calculated maximum value of the preset function when the difference between the maximum value of the preset function calculated at the first current position of the focus lens and the maximum value of the preset function calculated at the previous position of the focus lens is less than or equal to a preset threshold value.

摘要： A method and apparatus for compensating hand-trembling of a camera with reduced time required for capture compensated images. The method may include: calculating exposure time proper for preventing hand-trembling using an AE (Automatic Exposure) algorithm during an image-capturing standby mode; executing image-capturing multiple times depending on the exposure time at the time of inputting a photographing signal through a photographing button, and detecting the amount of hand-trembling at each time of image-capturing. The storing of images can be selected by a preset number of required images from the captured images as resultant images, the images being sequentially stored from an image having a lowest amount of hand-trembling as a resultant image, whereby an image with reduced hand-trembling can be obtained.

摘要： In a shutter device for use with a camera lens assembly, the shutter device includes a shutter base, a shutter blade is rotatably mounted on the shutter base, a magnet movably coupled to the shutter base so as to enable rotation of the shutter blade, and a yoke extending lengthwise while facing the magnet wherein the movement range of the shutter base is limited within a length of the yoke. The zoom-in/zoom-out operation is enabled by moving only the shutter base, thus enabling a compact size fabrication of the camera lens assembly. The shutter blade is easily installed adjacent to a diaphragm, and the operational speed of the shutter blade is controlled by adjusting the structure of an electronic coil.
