Communication apparatus and optical device thereof

A communication apparatus for performing mobile communication, the communication apparatus comprising:

• a housing having a first surface and a second surface, wherein the first surface and the second surface are opposed to each other;
• a first optical module partially exposed to the first surface of the housing, and capturing a first image corresponding to the first surface of the housing;
• a second optical module partially exposed to the second surface of the housing, and capturing a second image corresponding to the second surface of the housing;
• a third optical module partially exposed to the second surface of the housing, and capturing a third image corresponding to the second surface of the housing;
• and
• an image processing module disposed within the housing and electrically connected with the first optical module, the second optical module and the third optical module, wherein the image processing module produces a 360-degree panoramic image according to the first image and the second image, and the image processing module obtains depth-of-field information of the second image or the third image according to the second image and the third image.
