Embodiment Construction

[0035] Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0036] figure 1 is a block diagram showing the structure of the camera system 100 according to the embodiment.

[0037] figure 1 Among them, the camera system 100 according to the present embodiment may be a digital camera, a mobile terminal including a camera (or a camera module), or the like.

[0038] The camera system 100 may include an imaging unit 110 , a display unit 120 , an input unit 130 , a storage unit 140 , and a controller 150 .

[0039] The imaging unit 110 photographs a subject to output image data (eg, raw image data). The imaging unit 110 forms an optical image of a subject, and detects the formed optical image as digital image data, that is, raw image data. The imaging unit 110 may include a lens system including at least one lens for forming an optical image of an object. The imaging unit may further ...

Abstract

Disclosed herein is a method of object tracking using a camera system. A preview image is displayed on a display unit of the camera system. A plurality of objects of interest is selected from the preview image. The plurality of objects of interest is tracked to determine respective priorities. Autofocus is performed based on a highest priority object of the plurality of objects of interest.

Description

technical field [0001] Embodiments of the present disclosure relate to a method of tracking an object using a digital camera and a camera system for object tracking that efficiently performs auto focus (AF) when tracking a plurality of objects. Background technique [0002] With the popularity of digital cameras, many people easily capture various images. Such a digital camera has an automatic mode function in order to allow beginners to easily take pictures, and to allow ordinary users to acquire high-quality images more conveniently. In order to obtain high-quality images, it is necessary to know the lighting status and the position of objects in the preview screen, and to adjust the autofocus (AF) accurately. [0003] In order to accurately adjust AF, it is necessary to know the position of the subject and use subject tracking algorithms to continuously track the subject. An example of a method of adjusting AF using a subject tracking algorithm may include continuous au...
