[0033] With the development of display technology, high refresh rate display devices are widely used in video monitoring, entertainment video and audio playback, real-time video connection and other scenarios with high real-time requirements. In order to display images more clearly, the prior art usually increases the refresh rate of the display device, for example, increases the full-screen refresh rate of the display device from 60Hz to 75Hz, 90Hz or 120Hz, or even experimentally to 144Hz. However, with the increase of the full-screen refresh rate of the display device, the power consumption of the display device is increased.

[0034] Therefore, the display control method, the display control device, the display control equipment and the display equipment are provided. Based on the case that the display area is divided into multiple display areas, each frame of image in continuous multiple frames of image is segmented and grouped to obtain multiple groups of sub-images corresponding to the multiple display areas. Therefore, the refresh rate of the corresponding display area can be determined based on the image change of each group of sub-images, and each display area is controlled to output according to the corresponding refresh rate, so that the refresh rate of the display area matches the actual required refresh rate of each group of sub-images. In this way, the corresponding group of sub-images with fast image change can be output at a high refresh rate, and the corresponding group of sub-images with slow image change can be output at a low refresh rate. In this way, the overall power consumption of the display equipment can be reduced to realize the display effect of high refresh rate with low power consumption.

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0036] Figure 1A A flowchart of a display control method according to an embodiment of the present application is shown. Figure 1B A schematic diagram of a display area of a display equipment divided into multiple display areas is shown. Figure 1C A flowchart of segmentation and grouping of M frames of image is shown. In at least one embodiment of the present application, as shown in Figure 1A The display control method includes the following steps S11-S14.

[0037] Step S11, M frames of continuous image are obtained, M is an integer not less than 1. Exemplarily, M frames of continuous image can be obtained from a video according to a preset acquisition period, for example, 1 acquisition per M frames of image. The number of M can be set according to actual needs, for example, M is set to 100, then 100 frames of continuous image are obtained. It should be noted that the acquisition period and the number of M can be selected and adjusted according to actual needs, and the embodiments of the present application do not limit this.

[0038] Step S12, each frame of image in M frames of image is segmented into N sub-images, the i-th sub-image of M frames of image constitutes the i-th group of sub-images, N groups of sub-images are obtained; wherein, N is an integer not less than 2, i is an integer not less than 1 and less than or equal to N, N groups of sub-images correspond to N display areas one by one, and N display areas are divided by the display area of the display equipment 10.

[0039] Exemplarily, as shown in Figure 1BAs shown, the entire display area A of the display device 10 can be pre-divided into N display areas, for example, the N display areas are A1, A2, ..., AN. Each frame of the M-frame image can be segmented based on the N display areas divided in the display area A, for example, by using the following formula (1) to segment each frame of the image:

[0040] I o =I / P formula (1);

[0041] Where I represents a frame of image, P is the image segmentation matrix, and P can be a 1×N matrix or an N×1 matrix, I o N sub-images are obtained by segmenting a single frame of an image.

[0042] The following is combined Figure 1C Explain the segmentation and grouping methods of the M-frame images, such as... Figure 1C As shown, the M consecutive frames are designated as I1, I2, ..., I... M For I1, I2, ..., I M Image segmentation is performed using the formula (1) above, resulting in N sub-images of I1, denoted as I. 11 I 12 ... I 1N The N sub-images of I2 are I 21 I 22 ... I 2N And so on, we get I M The N sub-images are I M1 I M2 ... I MN Let I1, I2, ..., I M The first sub-image I 11 I 21 ... I M1 As the first group of sub-images, I1, I2, ..., I M The second sub-image I 12 I 22 ... I M2 As the second group of sub-images, and so on, I1, I2, ..., I M The Nth sub-image I 1N I 2N ... I MN As the Nth sub-image group, N sub-image groups are obtained. Among them, the first sub-image group corresponds to the first display area A1, the second sub-image group corresponds to the second display area A2, and so on, with the Nth sub-image group corresponding to the Nth display area AN.

[0043] Step S13, determining the refresh rate of the corresponding display area based on the image change of each group of sub-images. Illustratively, step S13 can be: determining the refresh rate of the corresponding display area based on the image change speed of each group of sub-images, so that the size of the refresh rate is adapted to the image change speed. For example, the first group of sub-images is M frames of sub-images of fish swimming, which has a faster image change, and the refresh rate of the corresponding display area can be determined as 90Hz; the second group of sub-images is M frames of sub-images of a calm sea surface, which has a slower image change, and the refresh rate of the corresponding display area can be determined as 60Hz.

[0044] Step S14, outputting the corresponding refresh rate to each display area to control each display area to output according to the corresponding refresh rate.

[0045] The above scheme determines the refresh rate of the corresponding display area based on the image change speed of each group of sub-images, and outputs the corresponding refresh rate to each display area, so that the refresh rate of each display area is matched with the image change speed of the sub-image actually needed to be displayed, which can reduce the overall power consumption of the display device 10, and realize high refresh rate display effect with lower power consumption.

[0046] It should be noted that the prior art full-screen high refresh rate increases the power consumption of the display device, which will cause the display panel and control components of the display device to have greater heating effect (temperature rise effect), thereby reducing the stability of the high refresh rate display effect. The above scheme of the embodiments of the present application reduces the overall power consumption of the display device 10, which is more helpful to alleviate the heating effect of the display panel and control components, increase the stability of the high refresh rate display effect, and improve the visual enjoyment.

[0047] In addition, the prior art usually alleviates the temperature rise effect caused by the increase in power consumption by improving the material or hardware capability, which not only consumes a long development and verification time, but also increases the overall structure size and complexity of the display device, is not conducive to the lightweight design of the display device, and also causes the cost to increase. The way of alleviating the temperature rise effect of the embodiments of the present application can also effectively alleviate the above problems of the prior art.

[0048] In an embodiment, as shown in Figure 2 Step S13 includes steps S21-S22.

[0049] Step 21, determining the corresponding image change rate based on the image data of the M frames of sub-images of each group of sub-images.

[0050] In one example, step S21 can include steps S221-S222.

[0051] Step S221, respectively determining the image data change rate matrix of the second frame of sub-images to the Mth frame of sub-images relative to the first frame of sub-images based on the image data of the M frames of sub-images of each group of sub-images.

[0052] Exemplarily, the image data can be pixel values of each pixel point, and step S221 can be: subtracting the pixel values of each pixel point of the second frame of sub-images from the pixel values of each pixel point of the first frame of sub-images one by one to obtain a pixel difference value matrix of each pixel point of the second frame of sub-images relative to the first frame of sub-images; and dividing the pixel difference value matrix by the pixel values of each pixel point of the first frame of sub-images one by one to obtain a pixel change rate matrix of the second frame of sub-images relative to the first frame of sub-images. In this way, the pixel change rate matrix of the Mth frame of sub-images relative to the first frame of sub-images can be determined.

[0053] For example, the pixel change rate of the second frame of sub-images of the first group of sub-images relative to the first frame of sub-images can be determined by the following formulas (2) to (5):

[0054]

[0055] wherein, I 11 (PI) is a pixel value matrix of I 11 , a1, a2, a3, a4 are respectively pixel values of each pixel point in I 11 , I 21 (PI) is a pixel value matrix of I 21 , b1, b2, b3, b4 are respectively pixel values of each pixel point in I 21 , ΔI 11 (PI) is a pixel difference value matrix of I 21 relative to each pixel point in I 11 , f 11 is a pixel change rate matrix of I 21 relative to I 11 , and PI represents a pixel point.

[0056] Step S222: determining a corresponding image change rate based on each image data change rate matrix.

[0057] Exemplarily, step S222 can be: determining an average value matrix of the corresponding image data change rate matrix based on each image data change rate matrix; and adding each average value in the average value matrix to obtain the corresponding image change rate.

[0058] For example, continuing to take the first group of sub-images as an example, the average value matrix of the pixel change rate matrix of the first group of sub-images can be determined by the following formula (6), and the image change rate of the first group of sub-images can be determined by formula (7):

[0059]

[0060] f 1ck =c1+c2+c3+c4 formula (7);

[0061] Among them, f 21 For I 31 Relative to I 11 The pixel change rate, f (M-1)2 For I M1 Relative to I 11 The pixel change rate, c1, c2, c3, and c4 are the average pixel change rates of each pixel in the M frames of the first group of sub-images, f 1ck The image change rate of the first group of sub-images.

[0062] It should be noted that, for the purpose of clearly illustrating the determination of the image change rate, the above example only uses a 2×2 matrix for the pixel value matrix of the sub-image. However, in practical applications, a 4×4 matrix is ​​usually used for the calculation of the pixel value matrix of the sub-image. The pixel value matrix of the sub-image in this embodiment can be a 4×4 matrix. The above example is not intended to limit the type of the pixel value matrix of the sub-image or the types of other matrices involved in the calculation. The pixel value matrix of the sub-image and other matrices involved in the calculation in this embodiment can be adjusted according to actual needs, and this embodiment does not impose any restrictions on this.

[0063] Step S22: Determine the refresh rate of the corresponding display area based on the image change rate of each group of sub-images.

[0064] In one implementation, such as Figure 3 As shown, before step S21, the display control method further includes the following steps S31 to S32.

[0065] Step S31: Extract features from the M-frame sub-images of each group of sub-images to obtain M-frame feature images. The feature images represent the features of the human eye-sensitive area in the sub-images.

[0066] For example, step S31 may involve using a feature extraction matrix to extract pixel values ​​of pixels located in the human eye-sensitive region from the M-frame sub-images of each group of sub-images. For instance, the pixel value matrix of the M-frame sub-images of each group of sub-images is a 4×4 rectangle. Taking the first frame sub-image of the first group as an example, I is represented by the following formula (8). 11 pixel value matrix I 11 (PI), the feature extraction matrix R is represented by the following formula (9), and the feature extraction matrix R is used to extract I. 11 After feature extraction by (PI), I is obtained. 11 Feature image I' 11 pixel value matrix I' 11 (PI) is expressed by the following formula (10):

[0067]

[0068] wherein, d 11 , d 12 , d 13 , d 14 , d 21 , …, d 44 are respectively pixel values of each pixel point in I 11 .

[0069] It should be noted that the human eye can quickly capture the pixel points at the four corners and the center region of the image 4, and thus the sensitivity of the human eye to these regions is higher, and the sensitivity of the human eye to the pixel points at the four edges of the image 4 is lower. The embodiment of the present application extracts the features of each group of M frames of sub-images using the feature extraction matrix described above, and can effectively obtain the human eye sensitivity features in each sub-image.

[0070] In step S32, the image data of the M frames of feature images of each group of sub-images is taken as the image data of the M frames of sub-images.

[0071] The above scheme takes the image data of the M frames of feature images corresponding to each group of sub-images as the image data for determining the image change rate, which not only effectively retains the features of the M frames of sub-images of each group, but also reduces the amount of image data calculation and improves the calculation speed, thereby speeding up the determination of the image change rate.

[0072] In an embodiment, as shown in FIG. 2, the plurality of refresh rates and the plurality of preset change intervals have a one-to-one correspondence relationship, and step S22 can include the following steps S41-S42. Figure 4

[0073] In step S41, based on the correspondence relationship, the first change interval in which the image change rate of each group of sub-images is located is determined.

[0074] For example, the correspondence relationship between the plurality of refresh rates and the plurality of preset change intervals can be represented by the following Table 1.

[0075] Table 1: Correspondence relationship between the plurality of refresh rates and the plurality of preset change intervals

[0076] Variation interval Refresh rate [1.5，2] 120 Hz [0.9，1.2] 90 Hz [0.75，0.8] 75 Hz [0.5，0.6] 60 Hz

[0077] In one example, after the image change rate of each group of sub-images is determined, the image change rate of a certain group of sub-images is taken as an example, and the image change rate is 0.76. Based on the above correspondence relationship, it can be determined that the first change interval in which the image change rate is located is [0.75, 0.8].

[0078] ​In another example, step S41 can also be: when the image change rate of each group of sub-images is outside each change interval, determine the neighboring interval of the corresponding image change rate from multiple change intervals; and take the neighboring interval with the larger interval value as the first change interval in which the corresponding image change rate is located. For example, if the image change rate of a group of sub-images is 0.7, its neighboring intervals can be determined from multiple change intervals as [0.5, 0.6] and [0.75, 0.8], and then [0.75, 0.8] is taken as the first change interval in which 0.7 is located. This ensures that the finally determined refresh rate meets the display requirements of the corresponding group of sub-images, avoiding a reduction in display quality.

[0079] Step S42: Use the refresh rate corresponding to the first change interval as the refresh rate of the corresponding display area.

[0080] For example, after determining the first variation range as [0.75, 0.8], 75Hz is used as the refresh rate of the corresponding display area.

[0081] The above scheme directly determines the refresh rate of the corresponding display area by the image change rate of each group of sub-images, which can match the refresh rate of each display area with the image change of the corresponding group of sub-images.

[0082] In one implementation, such as Figure 5 As shown, multiple refresh rates correspond to multiple preset change ranges, and step S22 may include the following steps S51 to S54.

[0083] Step S51: Determine the corresponding average rate of change based on the image change rates of the N sub-images. For example, step S51 can be determined using the following formula (11):

[0084] fc = (f 1ck +f 2ck +L+f Nck ) / N formula (11);

[0085] Among them, f 1ck The image change rate of the first group of sub-images, f 2ck f represents the rate of change of the second group of sub-images, and so on. Nck Let be the rate of change of the Nth sub-image.

[0086] Step S52: Based on the correspondence, determine the first change interval of the image change rate and the second change interval of the average change rate of each group of sub-images.

[0087] Step S52 can be implemented by referring to the above-mentioned implementation process of step S41, and will not be repeated here.

[0088] Step S53, determining a target variation interval of each group of sub-images based on the difference between the first variation interval and the second variation interval.

[0089] In one example, step S53 can be: in the case that the first variation interval and the second variation interval are adjacent intervals, taking the first variation interval as the target variation interval. For example, the first variation interval is [0.5, 0.6] and the second variation interval is [0.75, 0.8], then [0.5, 0.6] is taken as the target variation interval.

[0090] In another example, step S53 can be: in the case that there is at least one interval between the first variation interval and the second variation interval, taking the adjacent interval of the first variation interval adjacent to the second variation interval as the target variation interval. For example, the first variation interval is [0.5, 0.6] and the second variation interval is [0.9, 1.2] or [1.5, 2], then [0.75, 0.8] is taken as the target variation interval.

[0091] Step S54, taking the refresh rate corresponding to the target variation interval as the refresh rate of the corresponding display area.

[0092] The above scheme compares the image variation rate of each sub-image with the average variation rate, adjusts the first variation interval based on the difference after comparison, obtains the target variation interval, and takes the refresh rate corresponding to the target variation interval as the refresh rate of the corresponding display area. Thus, the refresh rate of each display area can tend to the average refresh rate, and the difference in refresh rate between each display area can be reduced, which is conducive to improving the display effect and improving the visual enjoyment.

[0094] Based on the refresh rate of each display area, the frame rate of each group of sub-images is determined to match the frame rate of each group of sub-images with the corresponding refresh rate;

[0095] Based on the frame rate of each group of sub-images, the corresponding target image is determined; for example, based on the frame rate of each group of sub-images, frames are extracted from the corresponding group of sub-images to form N groups of target images (for reference Figure 8 ), and the number of frames of each group of target images can be less than or equal to M;

[0096] The corresponding refresh rate and the corresponding target image are respectively output to each control component, so that the control component controls the display area to output the target image according to the corresponding refresh rate. For example, referring to Figure 8 , the corresponding refresh rate and the target image of each control component are respectively output.

[0097] The functions of each module in each device in the embodiments of the present application can be referred to the corresponding description in the above method, which will not be repeated here.

[0105] Figure 7 A structural block diagram of a display control device according to an embodiment of this application is shown. Figure 7 As shown, the display control device includes a memory 71 and a processor 72. The memory 71 stores a computer program that can run on the processor 72. When the processor 72 executes the computer program, it implements the display control method in the above embodiments. The number of memories 71 and processors 72 can be one or more.

[0106] The display control device also includes a communication interface 73, which is used to communicate with external devices and perform data exchange and transmission. If the memory 71, processor 72, and communication interface 73 are implemented independently, they can be interconnected via a bus to complete communication with each other. This bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. This bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 7 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0107] Optionally, in a specific implementation, if the memory 71, processor 72, and communication interface 73 are integrated on a single chip, then the memory 71, processor 72, and communication interface 73 can communicate with each other through an internal interface.

[0108] This application also provides a display device, such as... Figure 8 As shown, the display device 10 includes a display panel ( Figure 8 (Unlabeled) and N control components. For example, the N control components are IC1, IC2, ..., ICN.

[0109] The display panel has a display area A, which is configured into N display zones, for example, the N display zones are the first display zone A1, the second display zone A2, ..., the Nth display zone AN. N control components correspond one-to-one with the N display zones; that is, IC1 corresponds to A1, IC2 corresponds to A2, and so on, with ICN corresponding to AN. Each of the N control components receives N refresh rates output by the display control device of any of the above embodiments, so that each control component controls the corresponding display zone to output and display according to the corresponding refresh rate. For example, IC1 receives the refresh rate determined based on the first group of sub-images and controls A1 to output and display the first group of sub-images according to that refresh rate. This reduces the overall power consumption of the display device 10, achieving a high refresh rate display effect with lower power consumption. Furthermore, the reduced overall power consumption of the display device 10 effectively alleviates the heat generation of the display panel and the N control components, thereby improving the stability of the high refresh rate display effect.
