Patent number: 8059956Abstract: 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.Type: GrantFiled: May 20, 2008Date of Patent: November 15, 2011Assignee: Samsung Electronics Co., Ltd.Inventors: Sung-Hoon Kim, Yong-Gu Lee, Doo-Sik Shin, Yeon-Jun Lee
