Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] see figure 1 , is a schematic structural view of the stereoscopic display device of the present invention. The stereoscopic display device includes an input unit 10 , a processing unit 20 and an output unit 30 .

[0041] The input unit 10 includes a controller 11 and a 3D video input unit 12, the controller 11 receives the input depth control signal and outputs it to the processing unit 20, and the 3D video input unit 12 is used to receive the input 3D video signal and outputs it to the processing unit 20. In this embodiment, the depth-of-field control signal received by the controller 11...

Abstract

The invention provides a stereoscopic display device with an adjustable field depth. The device comprises an input unit, a processing unit and an output unit, wherein the input unit is used for receiving a 3D video signal and a field depth control signal which are input from the external; the processing unit is used for receiving the field depth control signal and the 3D video signal and adjusting the field depth of a 3D video according to the field depth control signal; and the output unit is used for outputting adjusted 3D video signal. After the field depth control signal is received by the device, the parallactic error information dx in the field depth control signal is analyzed, a left eye view and a right eye view in the 3D video signal are amplified by utilizing the parallactic error information, the resolution ratio of the amplified views in the horizontal direction exceeds the resolution ratio of a 3D image not divided, different parts of the left eye view and the right eye view are intercepted according to field depth variation information stating whether the field depth is increased or reduced in the field depth control signal and the stereoscopic effect type of the 3D image, and a purpose of adjusting the field depth is achieved.

Description

technical field [0001] The invention belongs to the stereoscopic display technology, and in particular relates to a stereoscopic display device with adjustable depth of field and a method for adjusting the depth of field. Background technique [0002] The display device has gone through the development from black and white display to color display, from spherical display to current flat display. The color display device is rich in colors, which perfectly reflects the colorful world; the flat display has no distortion, and can accurately present the image to the viewer. These are undoubtedly major advances in the display field. However, the above-mentioned display device is still a two-dimensional display device, and what is presented to the viewer is a two-dimensional image, which cannot make the viewer experience the three-dimensional sense of the real world. The essential factor is that in the two-dimensional image, the depth information contained in the three-dimensional ...
