Embodiment 1

[0087] Taking the conventional 7-viewpoint grating stereoscopic display device as an example, N=7.

[0088] When the original image signal is 7-viewpoint naked-view image information, the device extracts a 2D image from the original image signal, and uses the extracted 2D image signal as reference image information. In addition, the display device also needs to acquire the depth information of the N-viewpoint view sequence. Wherein, when acquiring the depth information of the N-viewpoint view sequence, the acquisition may be performed with reference to content between sub-pictures in the original image signal.

[0089] After extracting the reference image information and obtaining the depth information of the N-viewpoint view sequence, the 3D sub-images of each viewpoint in the N-viewpoint can be synthesized according to the reference image information and the depth information of the N-viewpoint view sequence, so that the N viewpoint view sequence.

Embodiment 2

[0104] Taking an 8-viewpoint grating stereoscopic display device as an example, that is, N=8.

[0105]When the original image signal is 8-viewpoint naked-view image information, the device extracts a 2D image from the original image signal, and uses the extracted 2D image signal as reference image information. In addition, the device also needs to acquire the depth information of the N-viewpoint view sequence. Wherein, when acquiring the depth information of the N-viewpoint view sequence, the acquisition may be performed with reference to an arrangement manner among sub-pictures in the original image signal.

[0106] After extracting the reference image information and obtaining the depth information of the N-viewpoint view sequence, the 3D sub-images of each viewpoint in the N-viewpoint can be synthesized according to the reference image information and the depth information of the N-viewpoint view sequence, so that the N viewpoint view sequence.

[0107] In this embodiment...

Embodiment 3

[0121] In this embodiment, the original image information is a 2D image signal, from which reference image information is extracted, and the depth information of the N-viewpoint view sequence is obtained according to the original image information and a corresponding algorithm, and according to the reference image information and the obtained The depth information of the N-viewpoint view sequence is synthesized into 3D sub-images of each viewpoint in the N-viewpoint, so that the N-viewpoint view sequence can be obtained.

[0122] In this embodiment, the view sequence of N viewpoints may include H display units, wherein each display unit may include N sub-pixel sets, wherein, in the N sub-pixel sets in one display unit, according to In order from right to left, from the second sub-pixel set to the i-th sub-pixel set, the disparity between each sub-pixel set and the first sub-pixel set constitutes an increasing sequence, from the i-th sub-pixel set to the N-th sub-pixel set , th...

Abstract

The invention discloses a signal processing method which includes the steps: acquiring original image information at least comprising an image; acquiring reference image information and N viewpoint viewgraph sequence depth information according to the original image information; and acquiring an N viewpoint viewgraph sequence according to the reference image information and the N viewpoint viewgraph sequence depth information. The N viewpoint viewgraph sequence comprises H viewport units, each viewport unit comprises N sub-pixel sets, the parallax between each sub-pixel set and the first sub-pixel set forms an increasing sequence from the second sub-pixel set to the i sub-pixel set according to the sequence from right to left in the N sub-pixel sets, the parallax between each sub-pixel set and the first sub-pixel set forms a decreasing sequence from the i sub-pixel set to the N sub-pixel set, and the i is a positive integer which is not less than N / 2 and not more than N-1. The invention further discloses a device for implementing the method.

Description

technical field [0001] The present invention relates to display technology, in particular to a signal processing method and device. Background technique [0002] At present, the naked-view stereoscopic display device is still in the research stage and has not been popularized in large quantities. Moreover, due to the limitations of the naked-view display technology and signal processing technology, the naked-view stereoscopic display device is not perfect. [0003] At present, the naked-eye three-dimensional (3D) autostereoscopic displays developed based on binocular parallax are mainly grating-type 3D autostereoscopic displays. It is formed by adding a grating on a 2D flat-panel display. The grating can be divided into cylindrical grating or slit grating, cylindrical grating is also called cylindrical lens grating or lenticular lens grating, and slit grating is also called visually impaired baffle or slit baffle. Using the principle of grating light splitting, the light e...
