Abstract
Disclosed is a multi-aperture camera system for improving depth accuracy through a focusing distance scan. The system includes a single optical system including a first aperture through which an RGB optical signal is input and a second aperture through which a non-RGB optical signal is input, the single optical system moving relative to an image sensor to be arranged at positions; an image sensor configured to obtain image sets corresponding to the positions as the single optical system moves to be arranged at the positions, wherein each image set includes an RGB image based on the RGB optical signal and a non-RGB image based on the non-RGB optical signal; and a depth determination unit configured to calculate a disparity in each image set to determine a depth of an object by using the disparity, wherein the first and second apertures have mutually intersecting central positions.
