AUTO FOCUSING IMAGE PICK-UP APPARATUS, TERMINAL INCLUDING THE SAME AND AUTO FOCUS CONTROLLING METHOD USING THE SAME

摘要

One embodiment provides auto-focusing adjustment imaging device and autofocus adjustment method uses. It includes at least one lens that automatic focusing adjustment imaging device, which includes: optical unit,; Image sensor cell, for optical signal to be entered the image information obtained from optical unit; Image processing unit, for extracting focusedimage information from converted information; Storage unit, for storing automatic focusing (AF) code value; Control unit generates a driving signal, for moving optical unit for detecting alternative frequency codes value corresponding to focusedimage information extraction by image processing unit; And driving device, for adjusting at least one lens position, according to driving signal. Alternative frequency codes value updates the image finally focused with alternative frequency codes value, to be quickly obtained the image of focusing, accurate focusing adjustment is carried out to obtain the quantity of high quality graphic, even if using increase or the variation of a use environment. ;The 2016 of copyright KIPO submissions
