Description

3D image control method

technical field

The present invention relates to a three-dimensional image control method, in particular to a naked-view three-dimensional image control method.

Background technique

In recent years, with the improvement of the quality of life, the display technology has been continuously improved. From the early black and white TV and color TV to the current high-definition, thin and flat TV, all of them mean that people are pursuing more realistic and natural image quality. In order to meet the demand for more realistic images, display technology has evolved from two-dimensional to three-dimensional to provide a visual experience of three-dimensional space. Nowadays, the stereoscopic display technology mostly adopts the way of binocular parallax to achieve. Therefore, to allow people to receive stereoscopic images, the left and right eyes must receive slightly different images respectively. The 3D image display technology can be roughly divided into glasses type and naked-view type. Among them, the naked-view type 3D image display technology does not need to wear special glasses, which is self-evident for users.

However, while the naked-view 3D image display technology is improving day by day, its display quality still has great room for improvement. Therefore, how to improve the existing 3D image display technology to enhance the image quality of 3D images is one of the problems that researchers should solve.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

Please refer to FIG. 1 , which is a schematic diagram illustrating the structure of a display device applicable to an embodiment of the present invention. The display device 1 has a plurality of sub-pixels 10 arranged in a plurality of rows and a plurality of columns. Moreover, the display device 1 defines a plurality of viewing angles, and each viewing angle corresponds to at least a part of the sub-pixels 10 to provide a viewing angle image. In practice, multiple light splitting elements 14 can be used to generate different viewing angles, and the light splitting elements 14 can be lenticular convex lenses, but not limited thereto. In addition, the display device 1 defines a plurality of viewing areas 12 parallel to each other, and each viewing area 12 corresponds to one of the viewing angles. By arranging the light-splitting elements 14 in an oblique manner, an angle θ can be formed between the visible regions 12 and the column direction in which the sub-pixels 10 are arranged.

In practice, the corresponding relationship between sub-pixels 10 and viewing angles is determined according to the number of viewing angles and the included angle θ, and adjacent sub-pixels 10 usually belong to different viewing angles. Therefore, taking the sub-pixel 100 among the sub-pixels 10 as an example, it is assumed that it is the sub-pixel 10 to be displayed in the visible area where the corresponding viewing angle is located. Due to the existence of the included angle θ, in addition to one of the sub-pixels 10 itself, the surrounding sub-pixels 10 belonging to other viewing angles will also fall into the visible area. Taking N viewing angles as an example, it can be represented by the following equation.

View1 _perceived ＝View1 _display +C ₁ ×(ViewN _display +View2 _display )

+C ₂ ×(View(N-1) _display +View3 _display )+...(1)

View2 _perceived ＝View2 _display +C ₁ ×(View1 _display +View3 _display )

+C ₂ ×(ViewN _display +View4 _display )+...(2)

.

.

.

ViewN _perceived ＝ViewN _display +C ₁ ×(View(N-1) _display +View1 _display )

+C ₂ ×(View(N-2) _display +View2 _display )+...(3)

Wherein, Viewi _perceived is the brightness of the sub-pixel 10 at the i-th viewing angle seen by the user, Viewi _display is the brightness of the sub-pixel 10 at the i-th viewing angle displayed by the display device, and Cj represents the sub-pixels except for the i-th viewing angle The degree of influence of the luminance of the sub-pixel 10 at other viewing angles other than 10 on the brightness of the sub-pixel 10 at the i-th viewing angle. In practice, Cj can be regarded as a weight value, and the weight value is related to the area occupied by the corresponding sub-pixel 10 in the original matrix in the corresponding viewable area. Further converting the above equation into a matrix representation, the following equation can be obtained.

Among them, C is the correction matrix, V _d is the output matrix, and V _p is the original matrix.

According to the above matrix, the elements of the original matrix correspond to the brightness of at least part of the sub-pixels 10 of the same column. Furthermore, the diagonal elements of the correction matrix are 1, and each row except the first row is a result of the rightward cyclic shift of the row above it. In practice, the inverse of the correction matrix can be multiplied by the original matrix to generate the output matrix. Furthermore, each element of the original matrix can be multiplied by a corresponding coefficient and added together to generate one of the plurality of elements of the output matrix. The above-mentioned coefficients are the elements of the inverse matrix of the correction matrix, so the above-mentioned coefficients are associated with the weight value represented by Cj.

Please refer to FIG. 1 and FIG. 2 at the same time, wherein FIG. 2 is a flow chart of the 3D image control method of this embodiment. The 3D image control method of this embodiment is applicable to the display device 1 shown in FIG. 1 , and includes the following steps. First, in step S20, an original matrix is provided. Wherein, each element of the original matrix corresponds to the brightness of one of the sub-pixels 10 in one of the perspective images. Next, in step S22, the original matrix and the correction matrix are operated in sequence to generate an output matrix. The display device 1 determines the brightness of one of the sub-pixels 10 of one of the viewing angle images according to the elements in the output matrix. Through the above calculation, the brightness of the sub-pixel 10 can be reduced to compensate the influence caused by the light leakage of its adjacent sub-pixels 10 . Therefore, the display device 1 can use the output matrix to determine images of each viewing angle, and further provide optimized display of 3D images.

Please refer to FIG. 3 , which is a schematic structural diagram of another display device for illustrating a 3D image control method according to another embodiment of the present invention. As shown in FIG. 3 , the display device 3 includes a plurality of sub-pixels 30 . Wherein, the sub-pixels 30 in the first column and the fourth column belong to the red sub-pixels, the sub-pixels 30 in the second column and the fifth column belong to the green sub-pixels, and the sub-pixels 30 in the third column and the sixth column belong to the blue sub-pixels. color sub-pixels. The viewable area 32 forms an angle ψ ₁ with the row direction of the sub-pixels 30 , wherein ψ ₁ is tan ⁻¹ (1/6), approximately equal to 9.46 degrees. The number marked on each sub-pixel 30 represents the viewing angle corresponding to the sub-pixel 30. For example, the sub-pixel 30 marked with "1" corresponds to the first viewing angle, and the sub-pixel 30 marked with "5" corresponds to the fifth viewing angle. The embodiment takes a total of 5 viewing angles as an example, but it is not limited thereto. Therefore, the sub-pixels 30 marked with the same number can form a corresponding viewing angle image. Taking the second viewing angle as an example, assuming that the sub-pixel 300 is the sub-pixel 30 to be displayed, it is most affected by the light leakage of the sub-pixel 302 and the sub-pixel 304 . Similarly, other viewing angles are most affected by the upper and lower sub-pixels 30 .

Therefore, the correction matrix, output matrix and original matrix can be described by the following equations respectively.

Wherein, the relative positional relationship of the sub-pixels 30 of each viewing angle is shown by the subscripts of the above-mentioned original matrix elements and output matrix elements. For example, the coordinates of the sub-pixel 30 of the third viewing angle are (x, y-2), and the sub-pixels 30 of the second viewing angle are located below the sub-pixels 30 of the third viewing angle, so their coordinates are (x, y-3). Moreover, the sub-pixel 30 of the first viewing angle is located below the sub-pixel 30 of the second viewing angle, so its coordinates are (x, y-4), and the coordinates of the sub-pixels 30 of the fourth viewing angle and the fifth viewing angle can be deduced by analogy. In practice, C ₁ may be a value less than 0.3, but not limited thereto. Although the present embodiment takes ψ ₁ approximately equal to 9.46° as an example, in practice, when ψ ₁ is between 8° and 11°, the mutual influence of the sub-pixels 30 at different viewing angles is similar to that of the present embodiment. Therefore, the original matrix, correction matrix and output matrix of this embodiment are applicable to display devices where ψ ₁ is between 8 degrees and 11 degrees, and those skilled in the art can properly adjust C ₁ to achieve the optimum the goal of.

Please refer to FIG. 4 , which is a schematic structural diagram of another display device for illustrating a 3D image control method according to another embodiment of the present invention. As shown in FIG. 4 , the display device 4 includes a plurality of sub-pixels 40 . Wherein, the sub-pixels 40 in the first column and the fourth column belong to the red sub-pixels, the sub-pixels 40 in the second column and the fifth column belong to the green sub-pixels, and the sub-pixels 40 in the third column and the sixth column belong to the blue sub-pixels. color sub-pixels. The viewable area 42 forms an included angle ψ ₂ with the row direction of the sub-pixels 40 , wherein ψ ₂ is tan ⁻¹ (1/3), approximately equal to 18.43 degrees. The numbers marked on the sub-pixels 40 represent the viewing angles corresponding to the sub-pixels 40 , and this embodiment also takes a total of 5 viewing angles as an example, but it is not limited thereto. Taking the second viewing angle as an example, assuming that the sub-pixel 400 is the sub-pixel 40 to be displayed, it is most affected by the light leakage of the sub-pixel 402 and the sub-pixel 404 . Similarly, other viewing angles are most affected by the upper and lower sub-pixels 40 . Furthermore, the arrangement of the sub-pixels 40 in this embodiment is the same as the arrangement of the sub-pixels 30 in the above-mentioned embodiments. Therefore, this embodiment can also apply the original matrix, correction matrix and output matrix when ψ ₁ is approximately equal to 9.46 degrees. In this embodiment, each sub-pixel 40 is less affected by its upper and lower sub-pixels 40 than in the foregoing embodiments, so the value of C ₁ selected in practice is also smaller than that of the foregoing embodiments. Although the present embodiment takes ψ ₂ approximately equal to 18.43 degrees as an example, in practice, when ψ ₂ is between 16 degrees and 20 degrees, the mutual influence of the sub-pixels 40 of each viewing angle is similar to that of the present embodiment. Therefore, the original matrix, correction matrix, and output matrix of this embodiment are applicable to display devices with ψ ₂ between 16° and 20°, and those skilled in the art can properly adjust C ₁ to achieve the optimum the goal of.

As shown in FIG. 5 , the display device 5 includes a plurality of sub-pixels 50 . Among them, the sub-pixels 50 in the first column and the fourth column are red sub-pixels, the sub-pixels 50 in the second column and the fifth column are green sub-pixels, and the sub-pixels 50 in the third column and the sixth column are blue sub-pixels. color sub-pixels. The viewable area 52 forms an included angle ψ ₃ with the row direction of the sub-pixels 50 , wherein ψ ₃ is tan ⁻¹ (1/9), approximately equal to 6.34 degrees. The numbers marked on the sub-pixels 50 represent the viewing angles corresponding to the sub-pixels 50 , and this embodiment also takes a total of 5 viewing angles as an example, but it is not limited thereto. Taking the third viewing angle as an example, assuming that the sub-pixel 500 is the sub-pixel 50 to be displayed, it is most affected by the light leakage of the sub-pixel 502 and the sub-pixel 504 . Secondly, the sub-pixel 500 is also affected by the light leakage of the sub-pixel 506 and the sub-pixel 508 , but its influence is smaller than that of the sub-pixel 502 and the sub-pixel 504 . Similarly, other viewing angles are most affected by the upper and lower sub-pixels 50 respectively.

Therefore, the correction matrix, output matrix and original matrix can be described by the following equations respectively.

Wherein, the relative positional relationship of the sub-pixels 50 of each viewing angle is shown by the subscripts of the above-mentioned original matrix elements and output matrix elements. Furthermore, since the sub-pixel 50 is most affected by its upper and lower sub-pixels 50 , in practice C ₁ is greater than C ₂ . Although the present embodiment takes ψ ₃ approximately equal to 6.34 degrees as an example, in practice, when ψ ₃ is between 5 degrees and 8 degrees, the mutual influence of the sub-pixels 50 of each viewing angle is similar to that of the present embodiment. Therefore, the original matrix, correction matrix and output matrix of this embodiment are applicable to display devices with ψ ₃ between 5 degrees and 8 degrees, and those skilled in the art can adjust C ₁ and C ₂ appropriately to achieve purpose of optimization.

Please refer to FIG. 6 , which is a schematic structural diagram of another display device for illustrating a 3D image control method according to another embodiment of the present invention. As shown in FIG. 6 , the display device 6 includes a plurality of sub-pixels 60 . Wherein, the sub-pixels 60 in the first column, the fourth column, the seventh column and the tenth column belong to the red sub-pixels, the sub-pixels 60 in the second column, the fifth column and the eighth column belong to the green sub-pixels, and the sub-pixels 60 in the third column belong to the green sub-pixels. The sub-pixels 60 in the first, sixth and ninth columns are blue sub-pixels. The viewable area 62 forms an included angle ψ ₄ with the row direction of the sub-pixels 60 , and ψ ₄ is tan ⁻¹ (2/3), approximately equal to 33.69 degrees. The numbers marked on the sub-pixels 60 represent the viewing angles corresponding to the sub-pixels 60 , and this embodiment also takes a total of 5 viewing angles as an example, but it is not limited thereto. Taking the second viewing angle as an example, assuming that the sub-pixel 602 is the sub-pixel 60 to be displayed, in practice, adjacent sub-pixels 60 of the same color can be selected as the basis for correction, but the present invention is not limited thereto. For example, adjacent sub-pixels 601 and 603 of the same color can be selected as the basis for correction. Taking the third viewing angle as an example, assuming that the sub-pixel 603 is the sub-pixel 60 to be displayed, then the adjacent sub-pixels 602 and 604 of the same color can be selected as the basis for correction, and so on for other viewing angles.

Therefore, the correction matrix, output matrix and original matrix can be described by the following equations respectively.
