According to an embodiment of the present application, there is provided an embodiment of a method for processing a display image for a video conference, where the steps shown in the flowchart of the figure may be performed in a computer system such as a set of computer executable instructions, and where a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different than here.
Fig. 1 is a flowchart of a method for processing a display image of a video conference according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step S102, acquiring each path of image of the video conference, wherein each path of image comprises images located in different conference places;
it should be noted that each participant is a single image, and each image includes images of participants located in different conference places and images of different conference places.
Fig. 2a is a schematic diagram of an application scene of a remote video conference according to an embodiment of the present application, and as shown in fig. 2a, only a part of the area (display area 1 in fig. 2 a) in the application scene displays images of different conference places, and an image of which conference place is displayed can be selected by a remote controller, or conference place information of the display area can be automatically displayed based on the speaking situation of the conference places.
For example, for local conference site a, if local conference site B is currently the main conference site, the display area of local conference site a is the screen of local conference site B, and if local conference site C is the main conference site, the display area of local conference site a is switched to the screen of local conference site C.
Fig. 2b is a schematic diagram of another application scenario of remote video conference according to an embodiment of the present application, in which one display screen respectively displays images of a plurality of conference sites, for example, the distribution of four conference sites is as shown in fig. 2 b.
In the two application scenes, no matter the scene displays all images or partial images, the background of the server stores the image data of 4 conference places. Only when a partial image is displayed, other image data is not displayed.
Step S104, determining the display parameters of each path of image in the same preset time period;
in executing step S104, the display parameters of the first several frames of images may be counted for each image.
Step S106, determining target display parameters according to the display parameters of each path of image;
and step S108, respectively adjusting each path of image according to the target display parameters.
Through the steps, the display parameters of each path of image of the video conference are processed to obtain a target display parameter, and then each path of image of the video conference is adjusted by using the target display parameter, so that the aim of automatically adjusting images of all parties participating in the video conference is fulfilled, the brightness, the saturation and the like of the images of all parties participating in the video conference are consistent, and the technical effect of improving the visual experience of conference users is achieved.
According to an optional embodiment of the present application, the number of the display parameters is multiple, and step S106 determines the target display parameter according to the display parameter of each path of image, and is implemented by the following method: respectively selecting one same display parameter from the multiple display parameters of each path of image; calculating one of the following values of the selected display parameter corresponding to each image: mean, variance, and mean square error; one of the numerical values is taken as a target display parameter.
In this step, one display parameter is selected from a plurality of display parameters of each image, for example, referring to fig. 2b, a total of 4 images are selected, a total of 4 identical parameters are selected, and then the average value, variance or mean square deviation of the 4 identical parameters is calculated as a target display parameter.
According to another alternative embodiment of the application, the display parameters comprise at least: image brightness, image contrast, image saturation, and image sharpness.
Counting the display parameters of each image in the same preset time period, wherein the display parameters comprise at least one of the following parameters: image brightness, image contrast, image saturation, and image sharpness.
The image brightness refers to the brightness of the image. Generally, if the gray scale value of the image is between [0, 255], the lower the luminance as the gray scale value is closer to 0, the higher the luminance as the gray scale value is closer to 255.
The image saturation refers to the number of the colors of the image, if the gray level of the image is [ Lmin, Lmax ], the more the intermediate value in the range of [ Lmin, Lmax ], the more the colors of the representative image are, the higher the image saturation is, the more the image looks brighter, and the adjustment of the image saturation can correct the overexposed or underexposed image, so that the image looks more natural.
Image contrast refers to the difference in gray levels between the highest gray level and the lowest gray level.
Image sharpness generally refers to the resolution of an image.
The image brightness may not be increased excessively, which may cause the shadow to catch up with the highlight, because the maximum gray value is fixed, the minimum gray value catches up with the maximum gray value quickly, which may affect the image saturation, image contrast and image sharpness.
In some optional embodiments of the present application, the step of calculating an average value of the display parameters of each image, where the display parameter selected from the multiple display parameters is image brightness, includes the following steps: determining a format type of the image, wherein the format type comprises: RGB format and YUV format; if the format type of the image is an RGB format, calculating the image brightness of each path of image according to a preset image brightness calculation formula, and calculating the average value of the image brightness of each path of image; and if the format type of the image is a YUV format, determining the value of the Y component of each image as the image brightness of each image, and calculating the average value of the image brightness of each image.
In this step, taking the image brightness as an example, the calculation process of the target display parameter is described in detail:
if the image is in RGB format, the brightness calculation formula is as follows:
luminance ═ R0.299 + G0.587 + B0.114.
If the image is in YUV format, the value of the Y component is the brightness value of the image.
For example, if the luminance values of the four images are: 189,186,200,190, the calculated average is (189+186+200+190)/4, 191.25, and 191 after rounding, wherein rounding may be downward rounding.
In this embodiment, 189,186,200,190 is also the average value of the brightness of the data of multiple frames in a single data.
In addition, the calculation of the average value can be exchanged for other algorithms, such as: variance, mean square error, etc., as long as the calculation is kept consistent.
In other optional embodiments of the present application, the step S106 determines the target display parameter according to the display parameter of each image, and may also be implemented by the following method: respectively calculating one of the following numerical values of each identical display parameter of each image: mean, variance, and mean square error; one of the numerical values of each of the same display parameters is collectively set as a target display parameter.
The method for calculating the target display parameter of the image described above is to select one display parameter (for example, image brightness) from a plurality of display parameters of each image, and then calculate the average value of the several selected display parameters as the target display parameter. In this step, the average value (which may be a variance or a mean square error) of each of the same display parameters for each of the images is calculated as a target display parameter.
For example, the average value of the image brightness, the average value of the image contrast, the average value of the image saturation, and the average value of the image sharpness of each image are calculated, and the calculated average values of these several display parameters are used together as the target display parameter.
It should be noted that any two or any three of the 4 display parameters may be selected as the target display parameter.
Fig. 3 is a schematic diagram after automatic adjustment of a display image of a video conference according to an embodiment of the present application, and as shown in fig. 3, the display image of each conference is automatically adjusted by using a target display parameter obtained through calculation, so that image brightness and the like of the display image are consistent, and the purpose of improving visual experience of conference users is achieved.

an obtaining module 40, configured to obtain each path of image of the video conference, where each path of image includes images located in different conference places;
it should be noted that each participant is a single image, and each image includes images of participants located in different conference places and images of different conference places.
Referring to the application scenario shown in fig. 2a, only a part of the area (display area 1 in fig. 2 a) displays images of different conference places, and the image of which conference place is displayed can be selected by a remote controller, or conference place information of the display area can be automatically displayed based on the speaking situation of the conference place.
For example, for local conference site a, if local conference site B is currently the main conference site, the display area of local conference site a is the screen of local conference site B, and if local conference site C is the main conference site, the display area of local conference site a is switched to the screen of local conference site C.
Referring to fig. 2b, in the application scenario, one display screen respectively displays images of a plurality of conference sites, and for example, the distribution of four conference sites is as shown in fig. 2 b.
In the two application scenes, no matter the scene displays all images or partial images, the background of the server stores the image data of 4 conference places. Only when a partial image is displayed, other image data is not displayed.
