[0052] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0053] Currently, naked-eye 3D screens have been used in many scenarios, such as large or small game equipment, large screens in shopping malls, screens on building exterior walls, portable terminals, etc. Naked-eye 3D screens can display images from two viewpoints, including a left image and a right image. When people watch naked-eye 3D screens with naked eyes, the left eye should see the right image and the right eye should see the left image, thus achieving the effect of seeing a three-dimensional image. However, due to factors such as refraction and diffraction of light, the left eye may see the left image and the right eye may see the right image. This phenomenon is called crosstalk.

[0054] Figure 1 is a schematic diagram of a crosstalk phenomenon provided by an embodiment of the present application. Figure 1 , the original image (i.e. the original image to be displayed) includes a left image and a right image. For example, the left image mainly displays the text "AAAAAA" and the right image mainly displays the image of a person. Figure 1 The display image before crosstalk compensation. After the crosstalk phenomenon occurs, the left image (text image) with crosstalk appears in the right image (character image) viewed by the naked eye.

[0055] In order to solve this problem, an embodiment of the present application provides a 3D image display method, which first determines crosstalk compensation data based on first viewpoint image data and crosstalk, and then performs crosstalk compensation on second viewpoint image data based on crosstalk compensation parameters. In this way, crosstalk can be eliminated. After the first viewpoint image and the second viewpoint image are subsequently projected, the naked eye will not be able to see the first viewpoint image on the second viewpoint image, that is, crosstalk between the left and right viewpoint images of the naked eye 3D screen is avoided.

[0056] Continue to see Figure 1 , after adopting the 3D image display method provided by the embodiment of the present application to compensate the crosstalk of the left image, see Figure 1 In the displayed image after crosstalk compensation, the naked eye will not be able to see the text image in the right image (human image).

[0057] The 3D image display method provided in the embodiment of the present application can be applied to a display device, which can be any type of naked-eye 3D display device. The embodiment of the present application does not limit the structure, type, size, etc. of the display device, nor does it limit the naked-eye 3D technology adopted by the display device.

[0058] The business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0059] Next, the 3D image display method provided in the embodiment of the present application is explained in detail.

[0060] Figure 2 This is a flow chart of a 3D image display method provided by an embodiment of the present application. Please refer to Figure 2 , the method comprises the following steps.

[0061] Step 201: Determine crosstalk compensation data based on first viewpoint image data and a crosstalk ratio, where the crosstalk ratio represents the degree of crosstalk of the first viewpoint image to the second viewpoint image.

[0062] In the embodiment of the present application, the method of processing the crosstalk of the left image to the right image and the method of processing the crosstalk of the right image to the left image may be the same. That is, the first viewpoint image data may be the image data of the left image or the image data of the right image.

[0063] In the case where the first viewpoint image data is the image data of the left image, the crosstalk rate represents the degree of crosstalk from the left image to the right image, and the crosstalk compensation data is used to eliminate the crosstalk from the left image to the right image. In the case where the first viewpoint image data is the image data of the right image, the crosstalk rate represents the degree of crosstalk from the right image to the left image, and the crosstalk compensation data is used to eliminate the crosstalk from the right image to the left image.

[0064] In the embodiment of the present application, the first viewpoint image data is the image data of the first viewpoint image, and the second viewpoint image data is the image data of the second viewpoint image. One of the first viewpoint image and the second viewpoint image is a left image, and the other is a right image. Both the first viewpoint image data and the second viewpoint image data are data that have not been crosstalk compensated.

[0065] In a possible implementation, the first viewpoint image data and the second viewpoint image data both include brightness data. That is, the embodiment of the present application can avoid crosstalk of the naked eye 3D screen by performing crosstalk compensation on the brightness data. Of course, in some other embodiments, the first viewpoint image data and the second viewpoint image data may also include RGB values, grayscale values, contrast, color saturation or other image data. The following text takes the first viewpoint image data and the second viewpoint image data as brightness data as an example for introduction.

[0066] In a possible implementation, before determining the crosstalk compensation data based on the first viewpoint image data and the crosstalk rate, the brightness value of each pixel in the first viewpoint image is determined based on the RGB value of each pixel in the first viewpoint image to obtain the first viewpoint image data. The first viewpoint image includes a plurality of pixels.

[0067] There are multiple implementation methods for determining the brightness value of each pixel in the first viewpoint image based on the RGB value of each pixel in the first viewpoint image, including the following methods 1 to 3.

[0068] Method 1: traverse each pixel in the first viewpoint image, obtain the RGB value of the currently traversed pixel, and determine the brightness value of the currently traversed pixel based on the RGB value of the currently traversed pixel. That is, determine the brightness values ​​of the multiple pixels serially.

[0069] Method 2: Acquire RGB values ​​of multiple pixels in the first viewpoint image at the same time, and determine the brightness values ​​of the multiple pixels based on the RGB values ​​of the multiple pixels at the same time, that is, determine the brightness values ​​of the multiple pixels in parallel.

[0070] Method 3: Each time the RGB values ​​of the first number of pixels in the first viewpoint image are obtained, the brightness values ​​of the first number of pixels currently obtained are determined based on the RGB values ​​of the first number of pixels currently obtained. That is, serial and parallel are used together to determine the brightness values ​​of the multiple pixels.

[0071] Among them, the first number is a preset value, and the first number can be determined according to the processor type, the number of processor cores, the computing power (referred to as computing power for short) of the display device, etc.

[0072] The above describes the implementation method of obtaining the brightness value included in the first viewpoint image data. The implementation method of obtaining the brightness value included in the second viewpoint image data is the same as the implementation method of obtaining the brightness value included in the first viewpoint image data, and will not be repeated here. It should be noted that the time of obtaining the second viewpoint image data can be any time before step 202, and the embodiment of the present application does not limit this.

[0073] It should be understood that the RGB value of each pixel includes R value, G value and B value, and the brightness value of each pixel can be obtained by calculating the brightness values ​​corresponding to the R value, G value and B value respectively, and then adding the calculated three brightness values.

[0074] The present application embodiment does not limit the specific implementation method of determining the brightness value based on the RGB value, and the specific implementation method can be referred to the relevant technology. Here is an example, according to the formula P = (P 255 -P0)(grayscale value / 255) g +P0 to calculate the brightness values ​​corresponding to the R value, G value and B value respectively. In this formula, P represents the brightness value corresponding to the R value / G value / B value of a pixel, the grayscale value represents the corresponding R value / G value / B value, the value of g can be the gamma value of 2.2, P 255 P represents the actual brightness value of a pure white pixel displayed by the display device, and P0 represents the actual brightness value of a pure black pixel displayed by the display device. 255 and P0 can be measured using relevant instruments.

[0075] After the first viewpoint image data is acquired, the crosstalk compensation data may be determined based on the first viewpoint image data and the crosstalk ratio.

[0076] In an embodiment of the present application, one implementation method for determining crosstalk compensation data based on the first viewpoint image data and the crosstalk rate is: determine the product of the first viewpoint image data and the crosstalk rate to obtain crosstalk image data; and determine crosstalk compensation data based on the crosstalk image data.

[0077] Exemplarily, let the crosstalk rate be T, let the first viewpoint image data be L, L includes brightness values ​​of m*n pixels, let the crosstalk image data be C, then, C=L*T, C also includes m*n values.

[0078] Among them, the crosstalk rate is, for example, 0.07, 0.1 or other values. It should be understood that the degree of crosstalk from the left image to the right image may be the same as or different from the degree of crosstalk from the right image to the left image, that is, the crosstalk rate of the left image to the right image and the crosstalk rate of the right image to the left image may be the same or different. The specific value of the crosstalk rate can be determined by measurement, for example, by measuring the crosstalk degree without crosstalk compensation for multiple times, and taking the average value of the crosstalk rate obtained by the multiple measurements as the crosstalk rate in step 201. The embodiment of the present application does not limit the method for determining the crosstalk rate.

[0079] It should be understood that the crosstalk image data can be regarded as the image data of the crosstalk image that the naked eye will see on the second viewpoint image when crosstalk compensation is not performed. In order to achieve the purpose of eliminating crosstalk, the crosstalk image needs to be compensated to a pure white brightness image (not visible to the naked eye), and the maximum value in the crosstalk image data represents the brightest degree of the crosstalk image. Therefore, after obtaining the crosstalk image data, the crosstalk compensation data can be determined based on the maximum value.

[0080] In a possible implementation, based on the crosstalk image data, an implementation method for determining the crosstalk compensation data is: determining the maximum value in the crosstalk image data to obtain the maximum crosstalk value; determining the difference between the maximum crosstalk value and the crosstalk image data to obtain the crosstalk compensation data.

[0081] For example, taking the crosstalk image data C including m*n values ​​as an example, the maximum value among the m*n values ​​is determined as the maximum crosstalk value, and the maximum crosstalk value is recorded as C. max , let the crosstalk compensation data be S, then, S = C max -C. It should be understood that S also includes m*n values, and the value of a certain position in S is C max Resulting from subtracting the value at the same position in C.

[0082] It should be understood that the above data (including first viewpoint image data, second viewpoint image data, crosstalk image data, crosstalk compensation data) are all positive numbers. This is because the current display device displays images in the form of RGB values, grayscale values, brightness values, etc., which are represented by positive numbers.

[0083] Step 202: Perform crosstalk compensation on the second viewpoint image data based on the crosstalk compensation data.

[0084] In the embodiment of the present application, the crosstalk compensation data may be added to the second viewpoint image data to perform crosstalk compensation on the second viewpoint image data, thereby eliminating the crosstalk of the first viewpoint image on the second viewpoint image.

[0085] Exemplarily, the second viewpoint image data is denoted as R, R includes m*n values, the second viewpoint image data after crosstalk compensation is denoted as R', and the crosstalk compensation data S=C max -C, then, R'=R+S=R+C max -C. It can be seen that, in the case where the crosstalk image corresponding to the crosstalk image data C is originally seen, if “C” is used to represent the crosstalk image, “(R+C max -C)” means the real displayed image, then, “(R+C max -C)+C=R+C max" indicates the image seen by the naked eye after crosstalk compensation, that is, the naked eye will see the second viewpoint image superimposed with a pure white image (it should be understood that the pure white here is not really white, but whitish, which is actually a gray image. The grayscale value of this gray image depends on C max size), but the first viewpoint image will no longer be seen.

[0086] In the above implementation, the crosstalk compensation data is obtained by subtracting the crosstalk image data from the maximum crosstalk value, and is a positive number. In other possible implementations, the crosstalk compensation data may also be obtained by subtracting the maximum crosstalk value from the crosstalk image data, so that the obtained crosstalk compensation data is a negative number. Subsequent subtraction of the crosstalk compensation data from the second viewpoint image data may also achieve the same effect as the above implementation.

[0087] Step 203: Based on the crosstalk-compensated second viewpoint image data, display the crosstalk-compensated second viewpoint image on the naked-eye 3D screen.

[0088] As can be seen from the above, in one possible implementation method, the second viewpoint image data after crosstalk compensation includes the brightness value of each pixel in the second viewpoint image after crosstalk compensation. Then, based on the second viewpoint image data after crosstalk compensation, the corresponding implementation method of displaying the second viewpoint image after crosstalk compensation on the naked-eye 3D screen can be: based on the brightness value of each pixel in the second viewpoint image after crosstalk compensation, determine the RGB value of each pixel in the second viewpoint image after crosstalk compensation; and display the second viewpoint image after crosstalk compensation according to the RGB value of each pixel in the second viewpoint image after crosstalk compensation.

[0089] Among them, based on the brightness value of each pixel in the second viewpoint image after crosstalk compensation, the specific implementation method of determining the RGB value of each pixel in the second viewpoint image after crosstalk compensation can refer to the method of converting the brightness value into the RGB value in the related art, which will not be introduced in detail in the embodiments of the present application.

[0090] As can be seen from the above, the method of processing the crosstalk of the left image to the right image can be the same as the method of processing the crosstalk of the right image to the left image. Then, the crosstalk processing of the second viewpoint image to the first viewpoint image can also be implemented by referring to steps 201 to 203, which will be introduced below.

[0091] In an embodiment of the present application, crosstalk compensation data is determined based on the second viewpoint image data and the crosstalk rate, where the crosstalk rate represents the degree of crosstalk of the second viewpoint image on the first viewpoint image; based on the crosstalk compensation data, crosstalk compensation is performed on the first viewpoint image data to eliminate the crosstalk of the second viewpoint image on the first viewpoint image; based on the crosstalk compensated first viewpoint image data, the crosstalk compensated first viewpoint image is displayed on the naked eye 3D screen.

[0092] Among them, the specific implementation method of determining the crosstalk compensation data based on the second viewpoint image data and the crosstalk rate is similar to step 201, the specific implementation method of performing crosstalk compensation on the first viewpoint image data based on the crosstalk compensation data is similar to step 202, and the specific implementation method of displaying the first viewpoint image after crosstalk compensation on the naked-eye 3D screen based on the first viewpoint image data after crosstalk compensation is similar to step 203, which will not be repeated here.

[0093] One implementation of determining the crosstalk compensation data based on the second viewpoint image data and the crosstalk rate is: determining the product of the second viewpoint image data and the crosstalk rate to obtain the crosstalk image data; and determining the crosstalk compensation data based on the crosstalk image data. The specific implementation method can refer to the specific implementation method of similar content in step 201, which will not be repeated here.

[0094] One implementation method of determining the crosstalk compensation data based on the crosstalk image data is: determining the maximum value in the crosstalk image data to obtain the maximum crosstalk value; determining the difference between the maximum crosstalk value and the crosstalk image data to obtain the crosstalk compensation data. The specific implementation method can refer to the specific implementation method of similar content in step 201, which will not be repeated here.

[0095] One implementation method of performing crosstalk compensation on the first viewpoint image data based on the crosstalk compensation data is: adding the crosstalk compensation data to the first viewpoint image data to obtain the first viewpoint image data after crosstalk compensation. The specific implementation method can refer to the specific implementation method of similar content in step 202, which will not be repeated here.

[0096] Wherein, before determining the crosstalk compensation data based on the second viewpoint image data and the crosstalk rate, the brightness value of each pixel in the second viewpoint image is determined based on the RGB value of each pixel in the second viewpoint image to obtain the second viewpoint image data. The specific implementation method can refer to the specific implementation method of similar content in step 201, which will not be repeated here.

[0097] The crosstalk-compensated first view image data includes the crosstalk-compensated brightness value of each pixel in the first view image. Based on this, one implementation method of displaying the crosstalk-compensated first view image on the naked-eye 3D screen based on the crosstalk-compensated first view image data is: based on the crosstalk-compensated brightness value of each pixel in the first view image, determine the crosstalk-compensated RGB value of each pixel in the first view image; and display the crosstalk-compensated first view image according to the crosstalk-compensated RGB value of each pixel in the first view image. The specific implementation method can refer to the specific implementation method of similar content in step 203, which will not be repeated here.

[0098] Next, please combine Figure 3The 3D image display method provided in the embodiment of the present application is explained again by way of example.

[0099] Figure 3 is a flow chart of another 3D image display method provided by an embodiment of the present application. Taking the elimination of crosstalk of the left image to the right image as an example, see Figure 3 , see Figure 3 , the method comprises the following steps.

[0100] Step 301: Obtain brightness data L of the left image, including the brightness value of each pixel in the left image (for example, the brightness value can be determined based on the RGB value).

[0101] Step 302: Calculate the brightness data of the left image crosstalked to the right image, ie, the crosstalk image data C, according to the crosstalk rate.

[0102] Step 303: Determine the maximum value C in the crosstalk image data C max , calculate the crosstalk compensation data S = C max -C.

[0103] Step 304: Obtain brightness data R of the right image, including the brightness value of each pixel in the right image.

[0104] Step 305: Based on the crosstalk compensation data S, crosstalk compensation is performed on the brightness data of the right image to obtain the brightness data R'=R+S after crosstalk compensation of the right image. That is, the brightness of the right image displayed on the basis of the pure white (whitened) image is calculated.

[0105] Step 306: convert the brightness data R′ of the right image after crosstalk compensation into RGB values ​​after crosstalk compensation of the right image.

[0106] Step 307: Based on the crosstalk-compensated RGB values ​​of the right image, the right image after crosstalk compensation is displayed on the naked-eye 3D screen. For example, based on the crosstalk-compensated RGB values ​​of the right image, the right image after crosstalk compensation is displayed by interlacing.

[0107] Among them, step 304 can be executed at any time before step 305, and this embodiment of the present application is not limited to this.

[0108] To summarize, in the embodiment of the present application, crosstalk compensation data is first determined based on the first viewpoint image data and crosstalk, and then crosstalk compensation is performed on the second viewpoint image data based on the crosstalk compensation parameters, so that the crosstalk can be eliminated. After the second viewpoint image after crosstalk compensation is displayed on the naked eye 3D screen, the naked eye will not be able to see the first viewpoint image on the second viewpoint image, that is, crosstalk of the first viewpoint image on the second viewpoint image is avoided.
