  • Patent number: 8059956
    Abstract: 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.

  • Publication number: 20100309323
    Abstract: An optical image stabilizer for a camera lens module, including a housing fixed to a case of the camera lens module, at least one piezoelectric actuator fixed to the housing, and an image sensor assembly housed in the housing. A driving tip of the piezoelectric actuator is curved in shape and makes a point contact with the image sensor assembly. If the piezoelectric actuator is driven, the image sensor assembly freely moves on a plane perpendicular to a photographing direction as the driving tip rubs against the image sensor assembly. This optical image stabilizer is simple in structure and easy to control, so it can be mounted in devices in which installation spaces are limited, like small digital cameras and mobile terminals.
