摘要： A method and an apparatus for taking pictures on a mobile communication terminal having a camera module are provided, which can control the photographing of an object in accordance with the motion of the object. The method includes generating a current frame by photographing an object, determining whether blurring has occurred in the current frame, measuring an amount of motion of the current frame if no blurring has occurred in the generated current frame, and storing the current frame if the measured amount of motion is greater than a pre-stored reference amount of motion.

摘要： Disclosed herein is a hot plugging device for optical transceiver modules. The hot plugging device comprises a module housing, latching grooves extended from prescribed positions of both sides of the module housing to one end of the module housing, respectively, sliding members extended in the longitudinal direction of the module housing and linearly movably accommodated in the latching grooves, respectively, and a rotating member rotatably attached to one end of the module housing for engaging ends of the sliding members with corresponding ends of the latching grooves, respectively, while the rotating member is placed at a prescribed angle to the longitudinal direction of the module housing. With the hot plugging device of the present invention, a locking unit of the module housing is easily released, and the release of the locking unit is maintained, whereby the module housing is easily separated from a cage. Also, a working space necessary to separate the module housing from the cage is reduced, whereby many more optical transceiver modules can be mounted. Furthermore, only latching pieces are deformed when the module housing is separated from the cage. Consequently, the present invention has an effect of preventing permanent deformation of the module housing or the cage or damage to the module housing or the cage.

摘要： An auto focus (AF) apparatus and method for a camera that improves the AF action by reducing the number of time and steps required of a conventional apparatus and method. An encoder initial value is detected by measuring an initial position of a lens unit by means of an encoder; matching the measured encoder initial value to an initial position value to which the lens unit is to move while performing the auto focus; performing the auto focus starting from the matched initial position value, and dividing a distance that the lens unit is to cover into sections corresponding to a preset number of steps; detecting an edge value which shows a brightness change for a contour of a subject for as many as the number of the preset steps. The AF is completed by moving the lens unit to a position corresponding to a maximum edge value selected from among the detected edge values.
