Problems solved by technology

[0005] Furthermore, the sensitivity of each user to the stereoscopic display signal is different, and the degree of stereoscopic perception of each user is also different; therefore, under the same parallax effect, some users may feel that the parallax is too large, the stereoscopic effect is too strong, and the eyes are extremely sensitive. Tired easily; some users may feel that the parallax is too small and the stereoscopic effect is not strong enough

Embodiment Construction

[0032] In order to reduce the reverse parallax in the inversion area and improve the stereoscopic display effect in the non-inversion area, the embodiments of the present invention provide an image signal processing method and device.

[0033] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] The two-dimensional image signal or two-viewpoint three-dimensional image signal is first converted into a two-dimensional image signal (usually the original two-dimensional image signal) and corresponding depth information (Depth), and the depth information can be expressed as (where, e is the distance between the two lenses of the virtual camera, which is usually taken as the interpupillary distance of the human eye, that is, 65mm, f is the focal length of the virtual camera, D is the parallax, and the Depth information is inversely proportional to the parallax. The existence of the virtual camera is ...

Abstract

The invention discloses an image signal processing method and device. By the adoption of the image signal processing method and device, reverse parallax of an inversion area can be reduced, and the three-dimensional display effect of a non-inversion area can be improved at the same time. The image signal processing method comprises the steps that an image signal and depth information of the image signal are obtained; the image signal is processed into N sub-view signals different in depth information; the N sub-view signals are processed into multiple view signals, wherein the parallax between every two adjacent sub-views is larger than the parallax between next two adjacent sub-views, and N is larger than 1.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic display, in particular to an image signal processing method and device. Background technique [0002] Autostereoscopic display is based on glasses-free 3D display technology. Glasses-free 3D display technology utilizes the left-eye view and right-eye view with parallax (the left and right eye views are also called sub-views, and for users, each sub-view corresponds to a viewpoint when displayed), which are displayed alternately at a certain frequency. The view for the left eye and the view for the right eye have parallax, so after the view for the left eye and the view for the right eye with parallax are displayed, the human brain synthesizes and generates stereoscopic vision. [0003] In autostereoscopic display, the received ordinary two-dimensional signal or two-viewpoint three-dimensional image signal is converted into subviews of N viewpoints, and the parallax between adjacent s...
