<p>Disclosed in an embodiment of the present invention are a depth-of-field retaining device, 3D display system and display method. The depth-of-field retaining device comprises: a 3D video signal input device, a position determining device, an image processing device, and a 3D video signal output device. The 3D video signal input device, the position determining device, and the 3D video signal output device are all connected to the image processing device. The 3D video signal input device transmits the obtained 3D video signals to the image processing device. The position determining device transmits the detected position information of both the viewer and the display screen to the image processing device. Based on the position information, the image processing device adjusts the spaces between various object points in the left and right eye view in 3D video signals to keep the depth-of-field fixed, and transmits the adjusted 3D video signals to the 3D video signal output device.</p> |
