Description

Image signal processing method and device
The present application is a divisional application of chinese patent application 201410128350.6 entitled "a method and apparatus for processing image signals" filed on 04/01/2014.
Technical Field
The present invention relates to the field of stereoscopic display technologies, and in particular, to a method and an apparatus for processing an image signal.
Background
Autostereoscopic displays are based on naked eye 3D display technology. The naked eye 3D display technology uses left and right eye views (left and right eye views are also called sub-views, and each sub-view corresponds to a viewpoint when displayed for a user) with parallax to be alternately displayed at a certain frequency, and since the left and right eye views have parallax, the left and right eye views with parallax are displayed, and then are synthesized by the brain of a person to generate stereoscopic vision.
In the auto-stereoscopic display, a received common two-dimensional signal or two-viewpoint three-dimensional image signal is converted into sub-views of N viewpoints, the parallaxes between adjacent sub-views are the same, the sub-views of the N viewpoints are synthesized into a multi-view and displayed, and because any two adjacent sub-views have the parallaxes, a user can watch a stereoscopic display image in each visual area (the display area of the two adjacent sub-views corresponds to one visual area).
As shown in fig. 1, if the received signal is converted into N sub-view signals, 1, 2, 3, … …, N-2, N-1, and N sub-views are sequentially arranged, and then arranged from 1 again; because every two adjacent sub-views have parallax, N-1 parallaxes exist between the first view and the Nth view; therefore, between two adjacent display periods, there are N-2 opposite parallaxes between the nth sub-view of the previous period and the first sub-view in the current period (two adjacent viewpoints, one view region), which become an inversion region, and the user cannot see a normal stereoscopic image in this region. As shown in fig. 1, the stereoscopic images can be normally viewed at positions a, b and c, and the stereoscopic images cannot be normally viewed at position d, which is an inversion region. As shown in FIG. 2, assume that the stereoscopic information of the 1-sub-view signal is D0The parallax of two adjacent pixel points is D, the inverse parallax entering the left eye and the right eye in the inversion area is | (N-1) × D |, and the display effect is that the image has serious reverse double images.
Moreover, the sensitivity of each user to the stereo display signal is different, and the stereo perception degree of each user is also different; therefore, under the same parallax effect, some users may feel that the parallax is too large, the stereoscopic vision effect is too strong, and the eyes are easily tired; some users may feel that the parallax is too small, and the stereoscopic vision effect is not strong enough.
Disclosure of Invention
The invention provides an image signal processing method and device, which can reduce the reverse parallax of an inversion region and improve the stereoscopic display effect of a non-inversion region.
The embodiment of the invention provides the following specific technical scheme:
acquiring an image signal and depth information of the image signal;
processing the image signal into N sub-view signals with different depth information, wherein the parallax between every two adjacent sub-view signals is gradually increased by changing the gray value of each point in the depth information gray map, and N is greater than 1;
processing the N sub-view signals into a multi-view signal.
Based on the technical scheme, in the embodiment of the invention, the depth information of each sub-view signal is adjusted according to the acquired depth information of the image signal, so that each sub-view has different depth information, and the parallax between every two adjacent sub-views is gradually reduced according to the arrangement sequence of each sub-view signal; in the prior art, if the parallax between each two adjacent sub-views is the same, for example, both the two sub-views are D, then the parallax of the inversion region between two adjacent display periods (each display period displays N sub-views) is N-1 inverse parallax, i.e., inverse (N-1) D, whereas in the present invention, since the parallax between two adjacent sub-views is gradually reduced (which can be described as D, K2D, K3D, …, K (N-1) D, wherein 1> K2> K3> … > K (N-1)), the parallax of the inversion region between two adjacent display periods is necessarily smaller than the inverse (N-1) D, so that the inverse parallax of the inversion region between two adjacent display periods in the synthesized multi-view signal is reduced, thereby reducing the influence of the inversion effect, and because the parallax of two adjacent view points in the multi-view signal is gradually changed, the stereoscopic display device can meet the requirement that a plurality of viewers with different stereoscopic sensibility watch simultaneously, thereby improving the stereoscopic display effect.

Detailed Description
In order to reduce the reverse parallax of the inversion region and improve the stereoscopic display effect of the non-inversion region, the embodiment of the invention provides an image signal processing method and device.
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The two-dimensional image signal or the two-viewpoint three-dimensional image signal is first converted into a two-dimensional image signal (often the original two-dimensional image signal) and corresponding Depth information (Depth), which can be expressed as(wherein e is a distance between two lenses of the virtual camera, usually, a distance between pupils of human eyes is taken as 65mm, f is a focal length of the virtual camera, D is parallax, Depth information is in inverse proportion to the parallax, the virtual camera exists in an auto-stereoscopic signal processing algorithm, most of related parameters of the virtual camera are the same as those of an actual 3D camera), different sub-view signals can be obtained by changing Depth information, and finally, the sub-view signals are combined into a multi-view signal.
The Depth information Depth is also expressed in the form of a gray scale map, and the minimum value and the maximum value of the Depth information are respectively corresponding to 0 and 255 of the gray scale map, and the other Depth information is sequentially corresponding to each gray scale value in the gray scale map in proportion. The process of converting a two-dimensional signal or a two-viewpoint three-dimensional image signal into a multi-viewpoint signal is shown in fig. 3, the two-dimensional image signal or the two-viewpoint three-dimensional image signal is converted into a combination of a new two-dimensional image signal and Depth information, the new two-dimensional image signal is generally the same as the original two-dimensional image signal, when a new sub-view signal is generated, different sub-view signals can be obtained only by changing the Depth information (changing the gray value of each point in a gray scale image), and the relation between Depth and parallax is known, and the parallax is changed by changing the Depth information. The sub-view signal 1 is generated from a new two-dimensional image signal and Depth1, the sub-view signal 2 is generated from a new two-dimensional image signal and Depth2, and the sub-view signal N is generated from a two-dimensional image signal and Depth, where Depth1, Depth2, … …, and Depth are not the same. The inventor found that in the prior art, the Depth information difference between two adjacent sub-view signals is the same, which may be denoted as Depth2-Depth 1-Depth 3-Depth 2- … … -DepthN-Depth (N-1), that is, in the N sub-view signals, the disparity between two adjacent sub-views is the same, and further, in the N sub-view signals, the disparity between two pixels corresponding to the same pixel coordinate in two adjacent sub-views is the same.
In the following embodiments, based on the above principle, the depth information is adjusted so that the disparity between every two adjacent sub-view signals in each obtained sub-view signal is different, so as to achieve the purpose of reducing the inverse disparity of the inversion region in the multi-view signal and providing multiple different disparity visual experiences.
In a first embodiment of the present invention, as shown in fig. 4, an image signal processing method is provided, which specifically includes the following steps:
step 401: an image signal and depth information of the image signal are acquired.
Step 402: the image signal is processed into N sub-view signals having different depth information.
Step 403: and processing the N sub-view signals into a multi-view signal, wherein the parallax between every two adjacent sub-view signals is gradually reduced, and N is greater than 1.
Wherein, regarding a two-viewpoint three-dimensional image signal, one view signal is used as a reference, depth information of the view signal used as the reference is calculated according to the difference between the two view signals, and a plurality of sub-view signals are obtained according to the view signal used as the reference and the depth information.
When a multi-view signal (namely an auto-stereoscopic signal) is generated by a two-dimensional image signal or a two-viewpoint three-dimensional image signal, N sub-view signals are generated in the middle, N is larger than 1, when the sub-view signals are generated, each sub-view signal corresponds to different Depth information, different sub-view signals can be obtained only by changing the Depth information (namely changing the gray value of each point in a Depth gray scale image), the Depth information and the parallax are in inverse proportion, the parallax is changed by changing the Depth information, and therefore the fact that different sub-view signals are obtained by changing the parallax when the Depth information is changed can be considered that different sub-view signals are obtained by changing the parallax.
Each sub-view signal is obtained by changing Depth information, so that the difference between the Depth of each two adjacent sub-view signals is not the same, but gradually increases, that is, the parallax gradually decreases.
In the embodiment of the invention, the depth information of the two-dimensional image signal or the two-viewpoint three-dimensional image signal can be adjusted in various ways, and only various different depth information can be obtained, wherein each depth information corresponds to one sub-view signal.
Preferably, after obtaining the image signal and the depth information of the image signal, scaling the gray value of each pixel of the depth information of the image signal according to different scaling ratios to obtain each sub-view signal;
or,
and respectively scaling the gray value of each pixel in the local area of the depth information of the image signal according to different scaling ratios to obtain each sub-view signal.
The change of the depth information of each adjacent sub-view signal is in inverse proportion to the change of the parallax of each adjacent sub-view signal, namely, when the depth information of each adjacent sub-view signal has an increasing change trend, the parallax of each adjacent sub-view signal has a decreasing trend.
Based on the characteristic, in the embodiment of the invention, the plurality of sub-view signals with different depth information are obtained by adjusting the depth information, so that the difference of the depth information between every two adjacent sub-view signals is different, that is, difference images obtained by subtracting the depth information of the two adjacent sub-view signals are different, and thus, the parallax of every two adjacent sub-view signals is different.
Preferably, the plurality of sub-view signals obtained by adjusting the depth information are such that, in each pixel corresponding to the same pixel coordinate in each sub-view signal, the disparity between two pixels corresponding to the same pixel coordinate in each two adjacent sub-views is gradually reduced; and in each difference value image obtained by subtracting the depth information of the adjacent sub-view signals, the pixel value of each pixel with the same pixel coordinate is gradually increased.
For example, as shown in fig. 5, if the disparity between the first sub-view signal and the second sub-view signal is D by default, the disparity between two adjacent sub-view signals in one visual cycle is D, k1D、k2D、……、kN-3D、kN-2D, wherein k1、k2、……、kN-3And kN-2Is coefficient of variation, and 1>k1>k2>……>kN-3>kN-2The disparity between the pixel in the last sub-view signal of one visual cycle and the pixel in the first sub-view signal of the next cycle is | (1+ k)1+......+kN-3+kN-2) D | is much smaller than (N-1) D | so that the inversion effect of the inversion region can be greatly reduced, and visual experiences with various parallaxes can be provided.
Preferably, the disparity between each two adjacent sub-view signals gradually decreases, and there are two cases:
the parallax between every two adjacent pixels is linearly reduced;
or,
the non-linearity of parallax between every two adjacent pixels is reduced.
Preferably, in each pixel corresponding to the same pixel coordinate in each sub-view signal, the non-linear reduction of the disparity between two pixels corresponding to the same pixel coordinate in each two adjacent sub-views may be such that the disparity between each two adjacent pixels satisfies f (x) Ax2+ Bx + C, where x represents the disparity coordinates of two adjacent sub-view signals, and the disparity coordinates of the N-1 st sub-view image signal and the nth sub-view image signal are N-1.
For example, as shown in fig. 6, the disparity of the 1 st and 2 nd viewpoints is D, and the disparity of the 2 nd and 3 rd viewpoints is k1D, disparity of 3 rd and 4 th viewpoints is k2D, by analogy, the parallax of the N-1 view and the N view is kN-2D, the reduction of parallax is linearly variable, i.e. D-k1D=k1D-k2D=……=kN-3D-kN-2D, the change straight line corresponds to the formula f (x) ═ Ax + B, where x is a parallax coordinate, the parallax coordinates of the 1 st and 2 nd sub-view signals are 1, the parallax coordinates of the 2 nd and 3 rd sub-view signals are 2, and so on, the parallax coordinates of the N-1 st and N th viewpoints are N-1, f (x) represents the parallax magnitude, the positive or negative of a determines whether the straight line is a rising straight line or a falling straight line, where a is a negative value, and the larger the value of a, the slower the falling is, that is, the rate of change of parallax is smaller. In this way, the parallax change is uniform, and the parallax changes regularly from large to small. As shown in fig. 7, for example, 5 sub-view signals are used, and the stereo information of 1 sub-view signal is assumed to be D0The disparity of the 1 st and 2 nd sub-view signals is D, the disparity of the 2 nd and 3 rd sub-view signals is 0.8D, the disparity of the 3 rd and 4 th sub-view signals is 0.6D, the disparity of the 4 th and 5 th sub-view signals is 0.4D, and the disparity of the inversion region is |2.8D |, where a in (x) ═ Ax + B is-0.2 and B is 1.2, the formula is f (x) — 0.2x +1.2, as shown in fig. 8.
For another example, as shown in fig. 9, in each pixel having the same pixel coordinate in each sub-view signal, the non-linearity of the parallax between every two adjacent pixels is reduced, and the variation curve conforms to the formula: (x) Ax2+ Bx + C, where x is the disparity coordinate, the 1 st sub-view signal and the 2 nd sub-view signal have a disparity coordinate of 1, the 2 nd sub-view signal and the 3 rd sub-view signal have a disparity coordinate of 2, and so on, the N-1 st sub-view signal and the N-1 st sub-view signal have a disparity coordinate of N-1, and f (x) is the disparity magnitude,whether the curve is an ascending curve or a descending curve is determined by the positive and negative of (2), and when the curve is a descending curve, the curve isThe value of 2A is a negative value, and determines the degree of slowness of curve descent, and the larger 2A, the more rapid the descent, i.e., the larger the rate of change in parallax, and the smaller 2A, the slower the descent, i.e., the smaller the rate of change in parallax, and in this manner, the number of views having large stereoscopic depth to be retained is small, and the number of views having small stereoscopic depth is large. For example, a display period has 5 view arrangements (i.e. 5 sub-view signals), and 1 view (1 sub-view signal) stereo information is assumed to be D0Where the parallax of the 1 st and 2 nd viewpoints is D, the parallax of the 2 nd and 3 rd viewpoints is 0.7D, the parallax of the 3 rd and 4 th viewpoints is 0.5D, the parallax of the 4 th and 5 th viewpoints is 0.4D, and the parallax of the inversion region is |2.6D |, as shown in fig. 10, when f (x) ═ Ax |2If a in + Bx + C is 0.05, B is-0.45, and C is 1.4, then f (x) is 0.05x2-0.45x +1.4 as shown in figure 11.
For another example, as shown in fig. 12, in each sub-view signal, in each pixel corresponding to the same pixel coordinate, the non-linear disparity between two pixels corresponding to the same pixel coordinate in each two adjacent sub-views decreases, and the variation curve conforms to the formula: (x) Ax2In this mode, + Bx + C, the number of retained views having a large stereoscopic depth is large, and the number of views having a small stereoscopic depth is small. For example, a display period has 5 view arrangements (i.e. 5 sub-view signals), and 1 view (1 sub-view signal) stereo information is assumed to be D0The 1 st and 2 nd view parallaxes are D, the 2 nd and 3 rd view parallaxes are 0.9D, the 3 rd and 4 th view parallaxes are 0.7D, the 4 th and 5 th view parallaxes are 0.4D, and the inversion region parallaxes are |3D |, as shown in fig. 13. When f (x) Ax2+ Bx + C where a is-0.05, B is 0.05, and C is 1, then f (x) is-0.05 x2+0.05x +1 as shown in FIG. 14.
When synthesizing a multi-view signal (namely, an autostereoscopic signal), acquiring each pixel at the same coordinate position in each sub-view signal, sequentially arranging the pixels according to the sequence of each sub-view to form a display period, and synthesizing the multi-view signal after sequentially arranging each pixel position.
Based on the same principle, in a second embodiment of the present invention, as shown in fig. 15, an image signal processing apparatus is provided, and for specific implementation of the apparatus, reference may be made to the description of the above method portion, and repeated descriptions are omitted, and the apparatus mainly includes:
an obtaining module 1501, configured to obtain an image signal and depth information of the image signal;
a first processing module 1502 for processing the image signal into N sub-view signals having different depth information;
a second processing module 1503, configured to process the N sub-view signals into a multi-view signal, where a disparity between every two adjacent sub-views gradually decreases, and N is greater than 1.
Preferably, the second processing module is specifically configured to:
linearly reducing the parallax between every two adjacent sub-views;
or,
the non-linearity of the parallax between every two adjacent sub-views is reduced.
Preferably, the second processing module is specifically configured to:
when the N sub-view signals are processed into multi-view signals, the parallax f (x) between every two adjacent sub-views is made equal to Ax2+ Bx + C, where x represents the disparity coordinates of two adjacent sub-view signals, and the disparity coordinates of the N-1 th sub-view signal and the nth sub-view signal are N-1.
Specifically, the first processing module is specifically configured to:
respectively zooming the gray value of each pixel of the depth information of the image signal according to different zooming ratios to obtain each sub-view signal;
or,
and respectively scaling the gray value of each pixel in the local area of the depth information of the image signal according to different scaling ratios to obtain each sub-view signal.
Based on the technical scheme, in the embodiment of the invention, the depth information of each sub-view signal is adjusted according to the acquired depth information of the image signal, so that each sub-view has different depth information, and the parallax between every two adjacent sub-views is gradually reduced according to the arrangement sequence of each sub-view signal; in the prior art, if the parallax between each two adjacent sub-views is the same, for example, both the two sub-views are D, then the parallax of the inversion region between two adjacent display periods (each display period displays N sub-views) is N-1 inverse parallax, i.e., inverse (N-1) D, whereas in the present invention, since the parallax between two adjacent sub-views is gradually reduced (which can be described as D, K2D, K3D, …, K (N-1) D, wherein 1> K2> K3> … > K (N-1)), the parallax of the inversion region between two adjacent display periods is necessarily smaller than the inverse (N-1) D, so that the inverse parallax of the inversion region between two adjacent display periods in the synthesized multi-view signal is reduced, thereby reducing the influence of the inversion effect, and because the parallax of two adjacent view points in the multi-view signal is gradually changed, the stereoscopic display device can meet the requirement that a plurality of viewers with different stereoscopic sensibility watch simultaneously, thereby improving the stereoscopic display effect.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
