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： Disclosed is a method of producing an electron-absorption modulator having a reverse mesa structure. In the electron-absorption modulator, a first clad of a first conductivity type, an active layer of the first conductivity type, a second clad layer of a second conductivity type and an ohmic contact layer of the second conductivity type are formed on a semiconductor substrate of the first conductivity type. Then, a predetermined mask pattern is formed on the ohmic contact layer. Afterwards, the ohmic contact layer is etched by using the mask pattern. Then, the second clad layer and the active layer below the ohmic contact layer are etched in the form of the reverse mesa structure to expose the first clad layer. Then, the first clad layer is etched at a predetermined depth in the form of a mesa structure.

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.
