Abstract

The invention provides a zoom control method and device. The zoom control method includes the steps of: displaying an input image on a display unit; displaying an object detection frame showing at least a part of an object included in the input image on the display unit; The input image performs a zoom operation, wherein the object detection frame is not located at the center of the input image, and the position of the object detection frame after performing the zoom operation is substantially the same as the previous position of the object detection frame before performing the zoom operation, wherein, when there is When there are a plurality of object detection frames, the zoom factor is determined based on the plurality of object detection frames and the input image. The zoom control method allows photographing a subject by automatically performing a zoom operation with an appropriate composition, and solves a problem in which a subject disappears from a screen due to the zoom operation.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2011-0118515 filed in the Korean Intellectual Property Office on Nov. 14, 2011, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] Embodiments relate to a method and apparatus for controlling a zoom operation and a digital photographing apparatus. Background technique [0003] Most recent digital cameras have optical zoom capabilities greater than 10x. The optical zoom function may mean a function of adjusting focus so that an object can become infocus according to its size. The optical zoom function can arbitrarily determine the change of angle of view from standard to telephoto and from wide-angle to standard. Users prefer zoom lenses over short-focus lenses because zoom lenses have a variety of angles of view, provide a sense of perspective to images, and can be used to capture distant distance object. [0004] Meanwhile, unlike the optical ...
