Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a method for determining the screen direction, which is applied to a device for determining the screen direction, such as a terminal or a server. Specifically, as shown in fig. 1, the method of determining the screen orientation includes:
step 101: and acquiring an image of a first preset position of a recorded image of the screen.
Specifically, when the screen direction is a first direction, the image of the first preset position comprises a first identification image; when the screen direction is the second direction, the first identification image is not included in the image of the first preset position. After the screen recording process is started, screen recording software starts to capture a screen and continuously generates a frame-by-frame recording image. The device for determining the screen direction acquires the recorded image and acquires an image of a first preset position of the recorded image.
In one example, the recorded image may be a YUV image. In the above description, "Y" represents brightness (Luminance), "U" represents chromaticity (chromaticity), and "V" represents saturation (chromaticity).
The device for determining the screen direction may be a terminal for installing screen recording software and recording images of the screen, or a terminal in communication connection with the terminal for installing screen recording software and recording images of the screen, that is, the image recording terminal may perform the operation for determining the screen direction, or the image receiving terminal may perform the operation for determining the screen direction.
In one example, the first identification image is an identification image on a navigation bar of an on-screen display, such as a cellular signal identification image or a wireless signal identification image. The type of the first marker image is not limited in this embodiment.
Step 102: and determining the screen direction when the recorded image is recorded according to the image at the first preset position of the recorded image.
Specifically, the screen direction determining means may determine the screen direction in recording the recorded image by analyzing the image at the first preset position.
When studying the iOS system, the inventors found that the iOS system has the following characteristics:
when the interface of the iOS system is in the vertical direction, namely the screen direction is in the vertical direction, a navigation bar in the screen and an identification image on the navigation bar are positioned at the top of the screen; when the interface of the iOS system is in the horizontal direction, namely the screen direction is the horizontal direction, the navigation bar and the identification image on the navigation bar are hidden.
2. The YUV image obtained by screen recording is always in the vertical direction.
Based on the above findings, the inventor believes that the screen direction when recording the screen image can be determined by determining whether the screen direction of the screen image is the first direction according to whether the image based on the first preset position includes the first identification image.
In one example, the designer may obtain a pre-recorded image of the screen when the screen direction is the first direction, mark the first identification image in the pre-recorded image with the calibration frame, and the device for determining the screen direction determines the first preset position by recognizing the position of the calibration frame.
In one example, the device for determining the screen direction identifies the image at the first preset position by an identification method based on a deep learning algorithm or other algorithms, determines whether the image at the first preset position includes a first identification image, determines the screen direction as the first direction if the determination is yes, and determines the screen direction as the second direction if the determination is not yes.
It should be noted that, as can be understood by those skilled in the art, in practical application, it may also be determined whether the image at the first preset position includes the first identification image in other manners, which are not listed here, and the present embodiment does not limit the determination of the specific determination method.
In one example, the first direction is a vertical direction and the second direction is a horizontal direction.
In one example, the recorded image of the screen is an image of an interface after the terminal where the screen is located retreats the application to the background, that is, a main interface image.
It should be noted that, after determining the screen direction of the recorded image, the device for determining the screen direction may perform various processing operations on the recorded image based on the screen direction of the recorded image, for example, determine the driving manner of the pixels of the screen at the receiving end based on the screen direction, so that the user does not need to tilt the head or adjust the direction of the receiving end to adapt to the recorded image. The present embodiment does not limit the subsequent operation of acquiring the screen direction of the recorded image.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, the method for determining the screen direction provided in the embodiment can determine whether the screen direction when the image is recorded is the first direction according to whether the image at the first preset position of the recorded image includes the first identification image or not under the condition that the App is returned to the background, and further determine the screen direction when the image is recorded. Since the screen direction of the recorded image is known, the device for determining the screen direction may perform various processes on the recorded image based on the screen direction to improve the viewing experience of the user.
A second embodiment of the present invention is directed to a method for determining a screen direction, and the second embodiment exemplifies another method for determining a screen direction when recording a recorded image according to an image of a first preset position in the first embodiment.
Specifically, as shown in fig. 2, the apparatus for determining the screen direction includes the following sub-steps of, based on the image at the first predetermined position, determining the screen direction when recording the recorded image:
step 201: and acquiring the characteristic information of the first type of pixels and the characteristic information of the second type of pixels in the image at the first preset position.
Specifically, when the screen direction is the first direction, the first type of pixels form a first identification image, and the second type of pixels are pixels except the first type of pixels in the image at the first preset position.
In one example, the screen is a screen of the terminal, and the first identification image is an identification image in the navigation bar. The inventors have found that regardless of the color of the navigation bar, the color of the identification image of the navigation bar may be very different from the color of the navigation bar itself. Therefore, the apparatus for determining the screen direction may determine the screen direction when the recorded image is recorded by analyzing the feature information of the pixels of the image at the first preset position.
In one example, the feature information of the first type of pixels is a luminance average value of the first type of pixels, and the feature information of the second type of pixels is a luminance average value of the second type of pixels. Where the luminance may be the "Y" component in the YUV image.
It should be noted that, as can be understood by those skilled in the art, in practical applications, in addition to determining whether the image at the first preset position includes the first identification image according to the brightness average value, it may also be determined whether the first preset position includes the first identification image according to other feature information of the pixel, and the present embodiment is not limited to determining whether the image at the first preset position includes the feature information of the pixel of the first identification image.
Step 202: and calculating a first difference value of the characteristic information of the first type of pixels and the characteristic information of the second type of pixels, and determining the screen direction according to a judgment result of whether the first difference value is greater than a first threshold value.
Specifically, since the color of the identification image of the navigation bar may be greatly different from the color of the navigation bar itself, a judgment basis may be provided for determining whether the image at the first preset position includes the first identification image by calculating a difference between the feature information of the first type of pixel corresponding to the first identification image and the feature information of the second type of pixel.
The following exemplifies a manner of determining the screen direction according to the determination result of whether the first difference is greater than the first threshold.
In a first example, the device for determining the screen direction determines that the screen direction is the first direction if the first difference is greater than the first threshold, and determines that the screen direction is the second direction if the first difference is not greater than the first threshold.
Specifically, if the first difference is greater than the first threshold, it is determined that the difference between the feature information of the first-type pixel and the feature information of the second-type pixel is relatively large, that is, the difference between the color of the first identification image of the first-type pixel and the color of the first background image is relatively large, and the image at the first preset position includes the first identification image, so the screen direction is the first direction. Conversely, if the first difference is not greater than the first threshold, the screen direction is the second direction.
In a second example, the first identification image comprises only one color. If the device for determining the screen direction determines that the first difference value is larger than the first threshold value, judging whether the difference values of the feature information between any two first-type pixels are smaller than a third threshold value; if the difference value of the characteristic information between any two first-class pixels is smaller than a third threshold value, determining the screen direction as a first direction; and if the difference value of the characteristic information between the two first-class pixels is not smaller than a third threshold value, determining that the screen direction is the second direction, and if the first difference value is not larger than the first threshold value, determining that the screen direction is the second direction.
Specifically, if the first difference is greater than the first threshold, it is indicated that the difference between the feature information of the first-type pixel and the feature information of the second-type pixel is relatively large, that is, the difference between the color of the first identification image of the first-type pixel and the color of the first background image is relatively large, and it is indicated that the image at the first preset position includes the first identification image under the maximum probability. In order to further improve the accuracy of the final judgment result, the device for determining the screen direction performs further judgment based on the feature information of the first-class pixels, and because the first identification image only contains one color, the feature information of the first-class pixels is the same or extremely close, the device for determining the screen direction judges whether the difference value of the feature information between any two first-class pixels is smaller than a third threshold value, and if the difference value is smaller than the third threshold value, the screen direction is the first direction. And if the condition that the first difference is larger than the first threshold value is not met, or the condition that whether the difference of the characteristic information between any two first-class pixels is smaller than the third threshold value is not met, the screen direction is the second direction.
It is worth mentioning that the screen direction is further judged based on the characteristic information of the first type of pixels, and the accuracy of the judgment result is improved.
In a third example, before determining the screen direction according to the judgment result of whether the first difference is greater than the first threshold, before or after calculating the first difference, the device for determining the screen direction acquires the feature information of the third type of pixels and the feature information of the fourth type of pixels in the image at the second preset position of the recorded image; when the screen direction is the first direction, the image at the second preset position comprises a second identification image, the third type of pixels form the second identification image, and the fourth type of pixels are pixels in the image at the second preset position except the third type of pixels. And calculating a second difference value of the characteristic information of the third type of pixels and the characteristic information of the fourth type of pixels. The device for determining the screen direction determines the screen direction according to the judgment result of whether the first difference is greater than the first threshold and the judgment result of whether the second difference is greater than the second threshold.
In one example, the means for determining the screen orientation determines whether the first difference is greater than a first threshold; if the first difference is larger than a first threshold value, determining that the screen direction is a first direction; if the first difference is not larger than the first threshold, judging whether the second difference is larger than a second threshold; if the second difference is larger than the second threshold, determining the screen direction as the first direction; and if the second difference is not larger than the second threshold, determining the screen direction as the second direction.
In another example, the means for determining the screen orientation determines the screen orientation by:
step 2021: and judging whether the first difference value is larger than a first threshold value. If so, go to step 2022, otherwise, go to step 2023.
Step 2022: and judging whether the difference value between the characteristic information of any two first-class pixels is smaller than a third threshold value. If yes, go to step 2025. Otherwise, step 2023 is performed.
Step 2023: and judging whether the second difference value is larger than a second threshold value. If so, go to step 2024, otherwise, go to step 2026.
Step 2024: and judging whether the difference value between the feature information of any two third-class pixels is smaller than a fourth threshold value. If so, go to step 2025, otherwise, go to step 2026.
Step 2025: the screen direction is determined to be a first direction.
Step 2026: and determining the screen direction as a second direction.
It is worth mentioning that the screen direction is determined according to the judgment results of the two preset positions, so that the accuracy of the determined screen direction is further improved.
In one example, the feature information of the third type of pixels is a luminance average value of the third type of pixels, and the feature information of the fourth type of pixels is a luminance average value of the fourth type of pixels.
It should be noted that, in practical applications, the first threshold may be determined according to a difference between the feature information of the second type of pixels and the feature information of the first type of pixels when the screen direction is the vertical direction, and the second threshold may be determined according to a difference between the feature information of the fourth type of pixels and the feature information of the third type of pixels, for example, if the screen direction is the vertical direction, the difference between the feature information of the second type of pixels and the feature information of the first type of pixels is 10, and the difference between the feature information of the fourth type of pixels and the feature information of the third type of pixels is 9, the first threshold is 9 or 10, and the second threshold is 8 or 9.
It should be noted that, in practical applications, to further improve the accuracy of the screen direction, a similar determination logic as in the third example may be adopted to determine the screen direction according to the image at the first preset position, the image at the second preset position, and the image at the nth preset position of the image … … at the third preset position, and the number of the preset positions is not limited in this embodiment. n is a positive integer.
The method for determining the screen direction according to the present embodiment will be described below with reference to the actual situation.
It is assumed that the first identification image is a wireless signal identification image, the second identification image is a cellular signal identification image, the characteristic information of the pixel is the luminance of the pixel, and the first threshold value and the second threshold value are equal to 10. Under the condition that App is moved back to the background, when the screen direction is the vertical direction, the screen interface is as shown in fig. 3, and when the screen direction is the horizontal direction, the screen interface is as shown in fig. 4, as can be seen from fig. 4 and 5, when the screen direction is the vertical direction, the image 301 at the first preset position includes the wireless signal identification image, and the image 302 at the second preset position includes the cellular signal identification image. Accordingly, the screen direction determining means may determine the screen direction based on the result of the determination of whether the wireless signal identification image is present in the image 301 of the first preset position and the result of the determination of whether the cellular signal identification image is present in the image 302 of the second preset position. Firstly, a screen recording process starts to capture a screen, and a frame-by-frame YUV image is continuously generated. The device for determining the screen direction extracts an image 301 (hereinafter referred to as a first pixel block) at a first preset position of the YUV image according to the coordinate range of the first preset position. The device for determining the screen direction calculates the average value of the luminance of the first type pixels 3011 corresponding to the wireless signal identification image 3011 in the first pixel block (i.e., the Y component of the pixel), and calculates the average value of the luminance of the pixels (second type pixels 3012) other than the first type pixels 3011 in the first pixel block. The device for determining the screen direction extracts an image 302 (hereinafter referred to as a second pixel block) at a second preset position of the YUV image according to the coordinate range of the second preset position. The screen direction determining means calculates the average value of the luminance of the third type pixels 3021 corresponding to the cellular signal identification image in the second pixel block (i.e., the Y component of the pixel), and calculates the average value of the luminance of the pixels other than the third type pixels 3021 in the second pixel block (the fourth type pixels 3022). A first difference value of the average value of the luminance of the first type of pixels 3011 and the average value of the luminance of the second type of pixels 3012 and a second difference value of the average value of the luminance of the third type of pixels 3021 and the average value of the luminance of the fourth type of pixels 3022 are calculated. If the first difference is greater than 10 and the second difference is greater than 10, it indicates that there is a radio signal identification image in the image 301 of the first predetermined location and there is a cellular signal identification image in the image 302 of the second predetermined location, so the screen direction is vertical. If the first difference is less than 10, or the second difference is less than 10, the screen direction is the horizontal direction.
The above description is only for illustrative purposes and does not limit the technical aspects of the present invention.
Compared with the prior art, the method for determining the screen direction provided in the embodiment can determine whether the screen direction is the first direction when the recorded image is recorded according to the judgment result whether the image at the first preset position of the recorded image includes the first identification image and the judgment result whether the image at the second preset position includes the second identification image when the App is returned to the background, so that the accuracy of the finally determined screen direction is improved.
The steps of the above methods are divided for clarity, and the implementation may be combined into one step or split some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, which are all within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.

The determining module 402 is configured to determine a screen direction when the recorded image is recorded according to the image at the first preset position.
In one example, determining the screen direction according to the image at the first preset position specifically includes: acquiring feature information of a first type of pixel and feature information of a second type of pixel in an image at a first preset position; when the screen direction is a first direction, the first type of pixels form a first identification image, and the second type of pixels are pixels except the first type of pixels in the image at the first preset position; calculating a first difference value of the characteristic information of the first type of pixels and the characteristic information of the second type of pixels; and determining the screen direction according to the judgment result of whether the first difference value is larger than the first threshold value.

In an example, determining the screen direction according to a determination result of whether the first difference is greater than the first threshold specifically includes: if the first difference is larger than the first threshold value, judging whether the difference of the characteristic information between any two first-class pixels is smaller than a third threshold value; if yes, determining the screen direction as a first direction.
In one example, the feature information of the first type of pixels is a luminance average value of the first type of pixels, and the feature information of the second type of pixels is a luminance average value of the second type of pixels.
In one example, the first identification image is an identification image on a navigation bar of the screen display.
