Abstract
The present embodiment relates to a dual camera module comprising: a first camera module including a first liquid lens and capturing a first image; and a second camera module including a second liquid lens and capturing a second image, wherein a viewing angle of the first camera module is smaller than a viewing angle of the second camera module, at least a part of the viewing angle of the first camera module is included in the viewing angle of the second camera module such that there is an overlapping area between the first image and the second image so as to enable a composite image formed by combining the first image and the second image to be generated, and when the first camera module is focused, a focal length of the first liquid lens is varied according to the distance between the first liquid lens and a subject, and when the second camera module is focused, a focal length of the second liquid lens is varied according to the distance between the second liquid lens and the subject.
