The first controller 55170 transmits the processed 2D image signal to the 3D image processing apparatus 55200 (55426). The second controller 55270 controls the second image processor 55220 to convert the received 2D image signal into a 3D image signal (55427), and transmits the converted 3D image signal to the display device 55100 (55428). . The first controller 55170 displays the received 3D image signal as a 3D image on the display unit 55130 (55429).

In the embodiment illustrated in FIG. 40, the first image processing unit 55120 processes the 2D image signal, and the second image processing unit 55220 converts 2D into 3D. Also included is an embodiment in which the processor 55220 converts the 2D image signal into 3D. In this case, the first controller 55170 may recognize that the image signal is 2D and transmit the image signal to the 3D image processing apparatus 55200.

41 to 43 correspond to a case in which an image receiver 5510 is provided in the 3D image processing apparatus 55200 to directly receive an image signal.

As shown in FIG. 41, when the 3D image processing apparatus 55200 receives the 3D image signal from the image source 55300 (55431), the second controller 55270 recognizes that the received image signal is the 3D image signal. In operation 55435, the second image processor 55120 is controlled to process the received 3D image signal. The second controller 55270 transmits the processed 3D image signal to the display apparatus 55100 (55436). The first controller 55170 displays the received 3D image signal as a 3D image on the display unit 55130 (55437).

As shown in FIG. 42, when the 3D image processing apparatus 55200 receives a 2D image signal from the image source 55300 (55441), the second controller 55270 recognizes that the received image signal is a 2D image signal. In operation 55443, the received 2D image signal is processed (55445), and the second image processor 55120 is controlled to convert the processed 2D image signal into a 3D image signal (55447). The second controller 55270 transmits the converted 3D image signal to the display apparatus 55100 (55448). The first controller 55170 displays the received 3D image signal as a 3D image on the display unit 55130 (55449).

The embodiment of FIG. 43 differs from the embodiment of FIG. 42 in that the first image processor 55220 processes the 2D image signal. As shown in FIG. 43, when the 2D image signal from the image source 55300 is received by the 3D image processing apparatus 55200 (55451), the second controller 55270 recognizes that the received image signal is a 2D image signal. In operation 55453, the received 2D image signal is transmitted to the display apparatus 55100 in operation 55454. The first controller 55170 controls the first image processor 55120 to process the received 2D image signal (55455), and transmits the processed 2D image signal to the 3D image processing apparatus 55200 (55456). The second controller 55270 controls the second image processor 55220 to convert the received 2D image signal into a 3D image signal (55457). The second controller 55270 transmits the converted 3D image signal to the display apparatus 55100 (55458). The first controller 55170 displays the received 3D image signal as a 3D image on the display unit 55130 (55459).

As described above, according to the exemplary embodiment of the present invention, the 3D image processing apparatus 55200 is detachably coupled to the display apparatus 55100 for processing the 2D image, so that the 3D image may be easily upgraded to 3D and the 3D contents may be played back.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
