AN APPARATUS, A METHOD, AND A COMPUTER PROGRAM PRODUCT FOR AUTOMATIC FOCUSING

摘要

An apparatus (500) comprises: an image detector (122) for capturing an image frame (FN), a driving unit (200) for adjusting focusing of light onto said image detector (122), and a pulse generating unit (120), wherein said pulse generating unit (120) is configured to generate one or more synchronization pulses (S11, S12) based on the timing of optical exposure of a predetermined portion (TRIGLN) of said image frame (FN), and said driving unit (200) is configured to perform said adjusting based on the timing of said one or more synchronization pulses (S11, S12).
