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.

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.
