APPARATUS FOR ADJUSTING AUTOFOCUS AND METHOD OF CONTROLLING THE SAME |
摘要 |
An apparatus for adjusting an autofocus and a method of controlling the same are provided. The apparatus includes an imaging device that photographs light from a subject so as to generate an image signal; a contrast calculation unit that calculates a first contrast value of an image from the image signal; a correction unit that corrects a luminance of the image signal if the calculated first contrast value is equal to or less than a reference value; and a focus adjustment unit that adjusts a focus by using a second contrast value that is calculated from the corrected image signal, thereby providing an improved focus adjustment function.
