3D depth camera provides the depth information of the subject that is information about the position and size of the three-dimensional object, whereas obtaining the planar image through the 3D depth camera. However, in a regular smartphone camera, each pixel signifies the intensity of the light received from a specific point in the image. Ordinary cameras can only obtain planar images and the camera is unable to determine how near or far away the object is. Furthermore, digital imaging technologies have become so diverse and progressive due to the integrated circuits (ICs), CMOS image sensor technology, and advanced packaging that they can have any camera capabilities integrated into them.
