As shown in fig. 1, a scene schematic diagram of the technical solution provided by the present invention includes a plurality of image monitoring devices, each image monitoring device is fixed at a different position, and image data at different positions can be monitored by each image monitoring device to obtain corresponding monitored image data. The display control equipment can be connected with the image monitoring equipment through a data acquisition line or a local area network, and the monitored image data is displayed through the display control equipment. The display control device is connected with the input device, and the brightness of the monitored image data is adjusted through the input device. The image monitoring equipment comprises a CPU and a GPU, and the brightness of pixel points in the monitored image data can be adjusted and rendered through the GPU to obtain the monitored image data with the adjusted brightness. It should be noted that the brightness in the present invention is not the brightness in the screen background, but the brightness corresponding to the RGB value of each pixel in the image, for example, the brightness of deep blue is lower than the brightness of light blue, and the RGB value of deep blue is lower than the value of light blue. The brightness of the monitoring image data can also be represented by HSV values, namely, RGB values in the monitoring image data are converted into HSV values based on OpenCV.

The brightness adjustment in the prior art is to adjust the brightness of the LED display lamp of the screen, which is different from the brightness adjustment of the present invention. The invention can adjust the brightness of a plurality of monitoring image data asynchronously and reversely, thereby reducing the brightness difference and contrast difference between all images and the environment.

The invention provides a display control method suitable for multiple terminals, as shown in fig. 2, a display control device displays monitoring image data through the following steps, specifically comprising:

step S110, obtaining image brightness values of monitoring image data respectively sent by a plurality of terminals, and classifying the monitoring image data into a first image set and a second image set according to the image brightness values, wherein the brightness value of the image in the first image set is greater than the brightness value of the image in the second image set. According to the technical scheme provided by the invention, the image brightness values of the monitoring image data respectively transmitted by the terminals are respectively received, and the monitoring image data are classified according to the image brightness values of the monitoring image data respectively transmitted by the terminals to obtain the corresponding first image set and second image set, so that the monitoring image data can be classified and classified for the first time according to the brightness difference of the monitoring image data.

In a possible implementation manner of the technical solution provided by the present invention, step S110 specifically includes:

and obtaining the corresponding monitoring image brightness value according to the RGB brightness value of each pixel point in the monitoring image data respectively sent by each terminal. In an actual scene, the larger the RGB value is, the larger the brightness of the corresponding detected image data is, that is, the closer the R value, the G value, and the B value in the RGB value are to 255, the larger the RGB brightness value is, the present invention obtains the RGB brightness value of each pixel point to obtain the corresponding monitored image brightness value, and the RGB brightness value may be regarded as an average value of the R value, the G value, and the B value in the monitored image data.

And comparing the brightness value of the monitored image with a preset brightness value, and classifying the corresponding image data into a first image set if the brightness value of the monitored image is greater than the preset brightness value. The preset brightness value may be preset, and if the monitored image brightness value is greater than the preset brightness value, it is proved that the corresponding image data is brighter, so that the corresponding image data is classified as the first image set at this time.

And if the brightness value of the monitored image is smaller than a preset brightness value, classifying the corresponding image data into a second image set. And if the brightness value of the monitored image is smaller than the preset brightness value, the corresponding image data is proved to be darker, so that the corresponding image data is classified into a second image set at the moment.

The primary classification of all the monitored image data according to the brightness of the monitored image data can be realized through the first image set and the second image set.

Step S120, acquiring a brightness value of an environment where the display control device is located to obtain an environment brightness value, and determining a set which needs brightness adjustment in the first image set and the second image set as an adjustment image set according to the environment brightness value. According to the technical scheme provided by the invention, the brightness value of the environment where the display control equipment is located is firstly obtained to obtain the environment brightness value, and at the moment, the sets which need to be subjected to brightness adjustment in the first image set and the second image set are judged according to the environment brightness value. When a set of adjusted images is obtained, there may be 3 adjustment cases.

The 1 st adjustment condition is that only the brightness value of the monitoring image data in the first image set is adjusted; the 2 nd adjustment condition is that only the brightness value of the monitoring image data in the second image set is adjusted; the 3 rd adjustment case is to adjust the brightness values of the monitored image data in the first image set and the second image set, respectively.

In a possible implementation manner of the technical solution provided by the present invention, step S120 specifically includes:

the method comprises the steps of acquiring an image of an environment where display control equipment is located to obtain environment image data, and determining the RGB brightness value of each pixel point in the environment image data to obtain a corresponding environment image brightness value. According to the invention, the environment image data can be obtained through the image acquisition device arranged at the display control equipment, so that the corresponding environment image brightness value can be obtained.

And acquiring a monitoring image brightness value of each monitoring image data in the first image set to obtain a first set average brightness value, and acquiring a first brightness difference value according to the first set average brightness value and an environment image brightness value. The invention can count the monitoring image brightness values of all the monitoring image data in the first image set to obtain the average brightness value of the first set. The larger the first brightness difference is, the larger the difference between the brightness displayed by the monitored image data in the first image set and the brightness in the environment is, and at this time, the contrast between the brightness in the display control device and the brightness in the environment may be relatively large, and the monitored image data is relatively bright at this time.

And acquiring a monitoring image brightness value of each monitoring image data in the second image set to obtain a second set average brightness value, and acquiring a second brightness difference value according to the second set average brightness value and the environment image brightness value. The invention can count the monitoring image brightness values of all the monitoring image data in the second image set to obtain the average brightness value of the second set. The larger the second brightness difference value is, the larger the difference between the brightness displayed by the monitored image data in the second image set and the brightness in the environment is, the larger the contrast between the brightness in the display control device and the brightness in the environment may be, and the monitored image data is darker.

And if the first brightness difference value is greater than a first brightness preset value, taking the first image set as an adjustment image set, and if the second brightness difference value is greater than a second brightness preset value, taking the second image set as an adjustment image set. The first brightness preset value and the second brightness preset value may be preset by an administrator.

When the first brightness difference value is larger than the first brightness preset value, it is proved that the brightness of the images in the first image set at this time exceeds the maximum limit which can be accepted by the administrator, so that the monitored image data in the first image set at this time needs to be adjusted, that is, the first image set is used as an adjusted image set.

When the second brightness difference is larger than the second brightness preset value, it is proved that the brightness of the images in the second image set is lower than the minimum limit that the administrator considers acceptable at the moment, so that the monitored image data in the second image set needs to be adjusted at the moment, that is, the second image set is used as an adjusted image set.

When the first brightness difference value and the second brightness difference value are respectively greater than the first brightness preset value and the second brightness preset value, it is proved that the brightness of the images in the first image set exceeds the maximum limit deemed to be acceptable by the administrator at the moment, and the brightness of the images in the second image set is lower than the minimum limit deemed to be acceptable by the administrator at the moment, so that the monitored image data in the first image set and the monitored image data in the second image set need to be adjusted at the same time, that is, the first image set and the second image set are simultaneously used as an adjusted image set.

Step S130, acquiring a set average brightness value of all monitoring image data in the adjustment image set, comparing the set average brightness value with the environment brightness value to obtain a brightness conversion trend value, and automatically adjusting the brightness of all monitoring image data in the adjustment image set according to the brightness conversion trend value. According to the technical scheme provided by the invention, when the monitored image data in the adjusting image set is determined to be required to be adjusted, linear adjustment is carried out, namely, a brightness conversion trend value is obtained by comparing the set average brightness value with the environment brightness value, and the monitored image data is adjusted according to the brightness conversion trend value, so that the adjusted monitored image data is more suitable for the current scene where the display control equipment is located.

In a possible implementation manner of the technical solution provided by the present invention, step S130 specifically includes:

and if all the monitored image data in the adjusted image set are judged to be the monitored image data in the first image set, acquiring the set average brightness value of all the monitored image data in the adjusted image set. At this time, the monitoring image data to be adjusted includes monitoring image data with higher brightness, and the monitoring image data with higher brightness needs to be reduced, so that the set average brightness value of the first image set is obtained at this time.

And carrying out difference weighting on the set average brightness value and the environment brightness value to obtain a first brightness conversion trend value, and carrying out brightness reduction adjustment on all monitored image data in the adjustment image set according to the first brightness conversion trend value. The invention obtains the first brightness conversion trend value according to the difference between the set average brightness value and the environment brightness value, and if the difference is larger, the corresponding first brightness conversion trend value is larger.

and if all the monitored image data in the adjusted image set are judged to be the monitored image data in the second image set, acquiring the set average brightness value of all the monitored image data in the adjusted image set. At this time, the monitoring image data to be adjusted includes the monitoring image data with lower brightness, and the monitoring image data with lower brightness needs to be enlarged, so that the set average brightness value of the second image set is obtained at this time.

And carrying out difference weighting on the set average brightness value and the environment brightness value to obtain a second brightness conversion trend value, and carrying out brightness increase adjustment on all monitored image data in the adjustment image set according to the second brightness conversion trend value. According to the invention, a second brightness conversion trend value is obtained according to the difference between the set average brightness value and the environment brightness value, and if the difference is larger, the corresponding second brightness conversion trend value is larger.

After the brightness of the monitoring image data in the first image set and/or the second image set is adjusted, the technical scheme provided by the invention can obtain the corresponding first display area and second display area according to the number of different images in the first image set and the second image set, and the monitoring image data in different image sets can be stored in different display areas, so that the monitoring image data can be classified and displayed according to different brightness.

In the technical solution provided by the present invention, as shown in fig. 3, step S140 specifically includes:

step 1401, selecting the number of all the monitoring image data in the first image set to obtain a first image number, and selecting the number of all the monitoring image data in the second image set to obtain a second image number. Through the mode, the invention can obtain the total quantity of the image data to be monitored.

Step S1402, initializing the preset display area according to the first image quantity and the second image quantity, and obtaining the preset display area with the corresponding number of video fields. According to the technical scheme provided by the invention, the initialization processing of the preset display area is firstly carried out according to the number of the first images and the number of the second images, for example, the number of the first images and the number of the second images are 8 in total, and at this time, the preset display area needs to be divided into 8 video fields, so that the purpose of displaying 8 monitoring image data is realized.

Step S1403, anchoring a plurality of video fields in a preset display area according to the first image number to further divide the first display area, and anchoring the video fields outside the preset display area to divide the video fields into a second display area. The present invention may first select and anchor the plurality of video fields to divide the first display area, which may be sequentially selected from the left side to the right side in the preset display area, for example, if the number of the first images is 4, then the number of the video fields in the first display area is 4 on the left side, and then the divided 4 video fields outside the preset display area may be the second display area.

Step S1404, obtaining a first horizontal separation line and a first vertical separation line for dividing the video bar in the first display area, where each video bar displays each monitored image data in the first image set. As shown in fig. 4, the video bar is obtained by separating the first transverse separation line and the first longitudinal separation line, in the actual using process, the distance between every two adjacent first transverse separation lines and first longitudinal separation lines is inversely proportional to the number of the monitored image data, one video bar displays one monitored image data, the first transverse separation line and the first longitudinal separation line play a role in separating different monitored image data, and the viewing error of the user is avoided.

Step S1405, adjusting the initial brightness values of the first horizontal separation line and the first vertical separation line according to the brightness value of each monitored image data in the first image set to obtain a first separation line brightness value. According to the technical scheme provided by the invention, the initial brightness values of the first transverse separation line and the first longitudinal separation line can be adjusted according to the brightness value of each monitoring image data in the first image set, so that the condition that the RGB values and brightness of two adjacent monitoring image data and the first transverse separation line and/or the first longitudinal separation line are relatively close and difficult to distinguish and view is avoided. Each of the first horizontal and vertical separation lines will have a corresponding initial luminance value during initialization.

When the initial brightness values of the first transverse separation line and the first longitudinal separation line are adjusted, the initial brightness values are compared with the set average brightness value in the first image set to obtain the separation line brightness difference value, the initial brightness values are adjusted according to the corresponding first constant multiple according to the separation line brightness difference value, and the adjustment can be calculated by the following formula,

wherein，

The adjusted luminance values for the first horizontal division line and the first vertical division line,

the initial luminance values of the first horizontal division line and the first vertical division line,

is a multiple of a first constant, and is,

a constant value is adjusted for the first brightness. By passing

the smaller, the

The larger the difference between the brightness values of the first horizontal separating line and the first vertical separating line and each monitoring image data in the first image set is, the larger the contrast is, and the easier the viewing is.

And after the brightness value of the first separation line is obtained, controlling the first transverse separation line and the first longitudinal separation line to display according to the RGB values of the corresponding brightness.

In one possible implementation, a second horizontal separation line and a second vertical separation line for dividing the video fields in the second display area are obtained, each video field displaying each monitored image data in the second image set. The video column in the second display area is obtained by separating the second transverse separation lines and the second longitudinal separation lines, in the actual use process, the distance between every two adjacent second transverse separation lines and the second longitudinal separation lines is in inverse proportion to the number of the monitoring image data, one video column displays two monitoring image data, the second transverse separation lines and the second longitudinal separation lines play a role in separating different monitoring image data, and the viewing error of a user is avoided.

And adjusting the initial brightness values of the second transverse separation lines and the second longitudinal separation lines according to the brightness value of each monitoring image data in the second image set to obtain the brightness value of the first separation line. According to the technical scheme provided by the invention, the initial brightness values of the second transverse separation line and the second longitudinal separation line can be adjusted according to the brightness value of each monitoring image data in the second image set, so that the condition that the RGB values and brightness of two adjacent monitoring image data and the second transverse separation line and/or the second longitudinal separation line are relatively close and difficult to distinguish and view is avoided. Each of the second horizontal and vertical separation lines will have a corresponding initial luminance value during initialization.

When the initial brightness values of the second transverse separation line and the second longitudinal separation line are adjusted, the initial brightness values are compared with the set average brightness value in the second image set to obtain separation line brightness difference values, the initial brightness values are adjusted according to the separation line brightness difference values according to corresponding second constant multiples, and the separation line brightness difference values can be calculated through the following formula,

wherein the content of the first and second substances,

the adjusted luminance values for the second horizontal division line and the second vertical division line,

the initial luminance values of the second horizontal division line and the second vertical division line,

is a multiple of a second constant, and is,

a constant value is adjusted for the second brightness. By passing

The separation line luminance difference value can be obtained,

the smaller, the

The larger the brightness value of the adjusted second transverse separation line and the adjusted second longitudinal separation line is, the larger the difference between the brightness value of each monitored image data in the second image set and the brightness value of each monitored image data in the second image set is, the larger the contrast is, and the larger the contrast is, the easier the viewing is.

And controlling the second transverse separation line and the second longitudinal separation line to display according to the brightness of the brightness value of the second separation line. And after the brightness value of the second separation line is obtained, controlling the second transverse separation line and the first longitudinal separation line to display according to the RGB values of the corresponding brightness.

When the monitoring image data in the first image set is adjacent to the monitoring image data in the second image set, namely, adjacent video fields exist to respectively play the monitoring image data in the first image set and the monitoring image data in the second image set, at this time, the adjacent separation line can be used as a fixed separation line, namely, the separation line is displayed with an initial brightness value and is not changed.

Through the above manner, according to the technical scheme provided by the invention, the first transverse separation line, the first longitudinal separation line, the second transverse separation line and the second longitudinal separation line can be adjusted in one step, the first transverse separation line and the first longitudinal separation line can be adjusted in a decreasing manner, and the second transverse separation line and the second longitudinal separation line can be adjusted in an increasing manner, so that the contrast between the first transverse separation line and the image monitoring data in the first image set, the contrast between the second transverse separation line and the image monitoring data in the second image set, the contrast between the second transverse separation line and the image monitoring data, and between the two adjacent image monitoring data are increased.
