Stereoscopic image display method

The present invention relates to a stereoscopic image display method, and more particularly to a stereoscopic image display method suitable for a polarizing panel.

With the advancement and development of science and technology, people's enjoyment of material life and spiritual level has always increased and never decreased. On the spiritual level, in this era of rapid technological change, people hope to achieve the imaginative effect of stereoscopic displays through stereoscopic displays; therefore, how to make stereoscopic images or stereoscopic images become stereoscopic images. Today's stereoscopic display technology is the desired goal.

Moreover, stereoscopic display methods such as polarizing glasses and shutter glasses are the mainstream of the current stereoscopic display technology.

Since the shutter glasses method alternately displays the left and right eye images, it is easy to have a feeling of image flickering, and it is easy to cause visual fatigue when viewed for a long time. In contrast, the polarized glasses method displays left and right eye images through different polarized lights, so that the feeling of image flicker can be avoided. According to the above, the viewing comfort of the polarized glasses method is higher than that of the shutter glasses, and the cost of the polarized glasses method is lower than that of the shutter glasses.

FIG. 1 is a flow chart of a method for displaying a stereoscopic image according to an embodiment of the invention. Referring to FIG. 1 , in the embodiment, the stereoscopic image display method is applicable to a polarizing panel having a plurality of odd pixel column units and a plurality of even pixel column units, wherein each odd pixel column unit may be an odd pixel of the polarizing panel. Columns, each even pixel column unit may be an even pixel column of the polarizing panel. These odd pixel column units display one of a left eye image or a right eye image, and these even pixel column units display the other of the left eye image or the right eye image. Here, the left eye image is, for example, a horizontally polarized light image, and the right eye image is, for example, a vertically polarized light image. Therefore, the left eye image and the right eye image are filtered by the polarized glasses and enter the left and right eyes of the user respectively to form a stereoscopic image. image. However, depending on the display mode, the left-eye image may be a vertically polarized image, and the right-eye image may be a horizontally polarized image, which is not limited by the present invention.

It is assumed here that the even pixel column unit of the polarizing panel displays the left eye image, and the odd pixel column unit of the polarizing panel displays the right eye image, and the stereoscopic image display method includes the following steps. First, the original left eye image and the original right eye image are received (step S110), wherein the original left eye image is processed to form a left eye image and has a plurality of even pixel data column pixel data and a plurality of odd pixel data column pixel data. The original right eye image is processed to form a right eye image and also has a plurality of odd pixel data column pixel data and a plurality of even pixel data columns pixel data pixel data pixel data pixel data pixel data, and then each idol of the original left eye image One of the plurality of pixel data columns of the left eye image displayed by the even pixel column unit of the polarizing panel after the interpolation of at least one of the two odd pixel data columns adjacent to the original left eye image is performed. (Step S120). And, each odd pixel data column of the original right eye image and at least one of the adjacent two pixel data columns of the original right eye image are interpolated as the right eye image displayed by the odd pixel column unit of the polarizing panel. One of the plurality of pixel data columns (step S130). Furthermore, the left eye image and the right eye image are combined to obtain a display screen (step S140). Here, the odd pixel data column of the display screen corresponds to the right eye image, and the even pixel data column of the display screen corresponds to the left eye image.

Finally, the display screen is written to the polarizing panel (step S150), and the left eye screen is displayed by displaying the right eye screen through the odd pixel column unit of the polarizing panel and the even pixel column unit passing through the polarizing panel. According to the above, based on the interpolation operation, the even pixel data of the display image contains the image information of all the original left eye images, so that the displayed left eye image is more complete than the traditional one, so that the image quality of the left eye image is naturally higher than Traditional polarized stereo display technology. On the other hand, based on the interpolation operation, the odd pixel data column of the display image also contains the image information of all the original right eye images, so that the displayed right eye image is also more complete than the traditional one, so that the image quality of the right eye image is good. Naturally, it will be higher than the traditional polarized stereo display technology.

2 is a schematic diagram of an original left eye image, an original right eye image, and a display screen according to an embodiment of the invention. Referring to FIG. 2, first, taking the original left-eye image as an example, each even pixel data column of the original left-eye image and at least one of the adjacent two odd-pixel data columns in the original left-eye image are interpolated. One of a plurality of even pixel data columns of the display screen.

Here, each of the even pixel data columns of the original left eye image is interpolated with one of the two adjacent odd pixel data columns, that is, the second pixel data column of the original left eye image (ie, the pixel data PD21, PD22, PD23, etc.) and the first pixel data column (ie, pixel data PD11, PD12, PD13, ..., etc.) and the third pixel data column (ie, pixel data PD31, PD32, PD33, ..., etc.) in the original left-eye image. One of the pixel data columns (i.e., pixel data XD21, XD22, XD13, ...) of the original left eye image after the interpolation operation is performed, that is, the pixel data PD41, PD42, PD43, ..., etc.) is interpolated with one of the third pixel data column and the fifth pixel data column (not shown) in the original left-eye image as the fourth pixel data column of the display screen (ie, pixel data XD41) , XD42, XD43, ..., etc.), and so on.

Further, the pixel data PD21 is interpolated with the vertically adjacent pixel data PD11 or PD31 as the pixel data XD21 of the display screen, and the pixel data PD22 is interpolated with the pixel data PD12 or PD32 as a display screen. Pixel data XD22, and so on. Taking the prime data PD21 as an example, the interpolation operation method is the average value of GR21 (ie, the grayscale value of the pixel data PD21) and GR11 (that is, the grayscale value of the pixel data PD11) or GR31 (that is, the grayscale value of the PD31). The grayscale value of the pixel data XD21. Considering the completeness of the image information, the image information retained by each even pixel data column (such as column 2 or column 4) and the previous odd pixel column (such as column 1 or column 3) are interpolated. The integrity will be higher, that is, the pixel data PD21 and the pixel data PD11 are interpolated, the pixel data PD22 and the pixel data PD12 are interpolated, and the rest are deduced by analogy.

In addition, since the left-eye picture is mainly composed of even-pixel data, it is possible to set a corresponding weight value for each pixel data, and then perform an interpolation operation according to the weight value. For example, the weight value WT1 of the prime data PD21 is set to 2, and the weight value WT2 of the pixel data PD11 and PD31 is set to 1, and the grayscale value of the pixel data XD21 = (GR21 × 2 + GR 11 × 1) / (2 + 1) Or (GR21 × 2 + GR31 × 1) / (2 + 1). In other embodiments, the weight value WT1 is greater than or equal to the weight value WT2, and when WT1 is equal to the weight value WT2, it is the same as the interpolation operation described above.

On the other hand, each even pixel data column of the original left eye image can be interpolated with two adjacent odd pixel data columns in the original left eye image as one of a plurality of even pixel data columns of the display image. That is, the second pixel data column of the original left eye image and the first pixel data column and the third pixel data column of the original left eye image are interpolated and used as the second pixel data column of the display screen, the original left eye. The fourth pixel data column of the image is interpolated with the third pixel data column and the fifth pixel data column of the original left eye image as the fourth pixel data column of the display screen, and the rest is deduced by analogy.

Further, the pixel data PD21 is interpolated with the pixel data PD11 and PD31 as the pixel data XD21 of the display screen, and the pixel data PD22 is interpolated with the pixel data PD12 and PD32 as the pixel data XD22 of the display screen. The rest is like this. Taking the data PD21 as an example, the grayscale value of the pixel data XD21 = (GR21 + GR11 + GR31) / 3. In addition, regarding the last even pixel data column, there is only one adjacent odd pixel data column, so the interpolation operation of the last even pixel data column and the adjacent odd pixel data column is similar to the above two. Insert the operation method.

In addition, the corresponding weight value can also be set for each pixel data, and then the interpolation operation is performed according to the weight value. For example, the weight value WT1 of the prime data PD21 is also set to 2, and the weight value WT2 of the pixel data PD11 and PD31 is also set to 1, and the grayscale value of the pixel data XD21 = (GR21 × 2 + GR 11 × 1 + GR 31 × 1) /(2+1+1). In other embodiments, the weight value WT1 is greater than or equal to the weight value WT2, and when WT1 is equal to the weight value WT2, it is the same as the interpolation operation described above.

Furthermore, in addition to being performed in one dimension, the interpolation operation can also be performed in a two-dimensional manner, that is, using a matrix for interpolation. Taking the pixel data PD22 as an example, a 3×3 matrix can be used for interpolation, that is, the pixel data PD22 is interpolated with the pixel data PD12, PD32, PD21, PD23, PD11, PD13, PD31, PD33 as The pixel data XD22 of the display screen, wherein the pixel data PD12 and PD32 are vertically adjacent to the pixel data PD22, the pixel data PD21 and PD23 are horizontally adjacent to the pixel data PD22, and the pixel data PD11, PD13, PD31, PD33 are obliquely adjacent to the pixel data. PD22. According to the above, the grayscale value of the data XD22=(GR11+GR12+GR13+GR21+GR22+GR23+GR31+GR32+GR33)/9, wherein GR11~GR13, GR21~GR23 and GR31~GR33 are pixel data PD11 respectively. Gray scale values of ~PD13, PD21~23 and PD31~PD33. Regarding the pixel data PD21, it is impossible to take a 3×3 matrix, and thus it is possible to adjust to take 3×2 or take at least one of two pixel data vertically adjacent to the pixel data PD21 for interpolation.

If the corresponding weight value is set for each pixel data, the interpolation operation can be performed according to the weight value. For example, the weight value WT1 of the prime data PD 22 is set to 4, the weight value WT2 of the pixel data PD12 and PD32 is set to 2, the weight value WT3 of the pixel data PD21 and PD23 is set to 1, and the weights of the pixel data PD11, PD13, PD31, and PD33 are set. When the value WT4 is set to 1, the grayscale value of the pixel data XD22=(GR22×4+GR12×2+GR32×2+GR21×1+GR23×1+GR11×1+GR13×1+GR31×1+GR33× 1) / (4 + 2 + 1 + 1 + + + + + 1 + 1). In other embodiments, the weight values WT1 ≧ WT2 ≧ WT3 ≧ WT4, and when the weight values WT1, WT2, WT3, and WR4 are the same, the interpolation operation method is the same as the interpolation operation method described above.

The above description is based on the original left-eye image, and the original right-eye image is roughly the same as the original left-eye image. The difference is that the original right-eye image is dominated by odd-pixel data. In other words, the first pixel data column (ie, pixel data PD11, PD12, PD13, ..., etc.) of the original right-eye image is interpolated with the second pixel data column (ie, pixel data PD21, PD22, PD23, ..., etc.) as The first pixel data column of the display screen (ie, pixel data XD11, XD12, XD13, ..., etc.), the third pixel data column of the original right eye image (ie, pixel data PD31, PD32, PD33, ..., etc.) and the second pixel data At least one of the column and the fourth pixel data column (ie, the pixel data PD41, PD42, PD43, ..., etc.) is interpolated and used as the third pixel data column of the display screen (ie, pixel data XD31, XD32, XD33, ... Etc), and so on.

And, in the manner that each odd pixel data column and one of the adjacent two even pixel data are interpolated, each odd pixel data column of the original right eye image (such as the first or third pixel data column) The image information retained by the interpolation operation with the next even pixel data column (such as the 2nd or 4th pixel data column) is higher, that is, the pixel data PD11 of the original right eye image is interpolated with the pixel data PD12. The operation is performed as the pixel data XD11, and the pixel data PD12 of the original right-eye image is interpolated with the pixel data PD22 as the pixel data XD12, and the rest is deduced by analogy.

In the manner that each odd pixel data column and the adjacent two even pixel data are interpolated, the first odd pixel data column has only one adjacent pixel data column, so the first odd pixel data column and phase The interpolation operation of the adjacent even pixel data column is similar to the interpolation operation of the above two.

In addition, in the above description, the original left eye image is mainly composed of odd pixel data, and the original left eye image is mainly composed of odd pixel data. The column is dominant, and the original right-eye image may be dominated by the even-pixel data column, and the above-mentioned interpolation operation modes are mutually reversed, and the embodiment of the present invention is not limited thereto.

In summary, in the stereoscopic image display method of the embodiment of the present invention, the original left eye image generates an even pixel data column (ie, a left eye image) of the display image through an interpolation operation, and the original right eye image is interpolated. An odd pixel data column (ie, a right eye image) that produces a display image. Therefore, when the left eye image and the right eye image are displayed through the polarizing panel, the image information is relatively complete, and the image quality is improved.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
