Claim One:
1. An apparatus for generating a depth image, the apparatus comprising: a camera unit configured to obtain any one of left and right RGB images, left and right RGB and IR images (RGB/IR images) and left and right IR images; and a first generating unit configured to: control the camera unit to obtain any one of left and right RGB images, the left and right RGB/IR images, and the left and right IR images, and generate a depth image from the left and right RGB images or the left and right IR images received from the camera unit; wherein the camera unit comprises: a first sensor unit configured to obtain any one of the left RGB image, the left RGB/IR image, and the left IR image; a second sensor unit configured to obtain any one of the right RGB image, the right RGB/IR image, and the right IR image; a light receiving unit configured to detect an intensity of illumination; at least one emission unit configured to emit an IR by being turned on or off in response to control of the first generating unit; and a splitter configured to disperse the IR emitted from the emission unit in a predetermined pattern; wherein the first generating unit comprises: a controller configured to control ON and OFF of the emission unit in response to an intensity of light detected by the light receiving unit; a synchronization unit configured to synchronize the left and right IR images from outputs of the first and second sensor units; and a second generating unit configured to generate the depth image from the left and right IR images received from the synchronization unit.
