[0065] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0066] Example 1

[0067] Figure 1 The flowchart of the screen display control method of the wearable device is as follows. In an embodiment of the present invention, a screen display control method of the wearable device includes steps S100 to S400:

[0068] Step S100: establishing a connection channel with a database, acquiring display content in real time, inputting the display content into a trained conversion model, and obtaining a display image library;

[0069] The display content is the video to be played, which is pre-stored in the database, and the user interacts with the database. The database can be a cloud database or a local database; after obtaining the display content, the display content is converted into some display images, and the conversion process is relatively easy. Because the video itself contains multiple frames of images, the core of the conversion process is to continuously eliminate some non-image data, such as audio information, etc.

[0070] Step S200: determining a sampling point according to the display image library, reading an image in the display image library based on the sampling point, generating a corrected brightness according to the read image, and obtaining a corrected brightness array corresponding to the image library;

[0071] The purpose of step S200 is to generate a brightness correction array corresponding to the image. The feature of the technical solution of the present invention is to adjust the brightness of the screen according to the "brightness" of the image. It should be noted that the image itself does not have a brightness parameter. The "brightness" of the image actually refers to whether the color tone of the image is bright.

[0072] Step S300: receiving a reference brightness input by a user, and determining display brightness in real time according to the reference brightness and the modified brightness array;

[0073] The corrected brightness array reflects the fluctuations in screen brightness relative to a reference brightness that is input by the user.

[0074] Step S400: receiving control information from the user in real time, and determining a display parameter with a higher priority according to the control information;

[0075] Step S400 is a necessary function, in which the user receives the user's control information, and the control information has a higher priority, and its purpose is to ensure that the user can freely adjust the brightness during video playback.

[0076] Figure 2 The first sub-flow chart of the screen display control method of the wearable device, wherein the steps of establishing a connection channel with the database, acquiring display content in real time, inputting the display content into the trained conversion model, and obtaining the display image library include steps S101 to S105:

[0077] Step S101: establishing a connection channel with a database to obtain display content in a video format in real time;

[0078] Step S102: extracting image information from the display content, and converting the image information into an image sequence;

[0079] Step S103: sequentially reading images in the image sequence, calculating the degree of overlap between the image and the previous image, and comparing the degree of overlap with a preset degree of overlap threshold;

[0080] Step S104: when the overlap reaches the overlap threshold, the corresponding image is deleted and the next image is read;

[0081] Step S105: Count the read images to obtain a display image library.

[0082] Steps S101 to S105 specifically describe the generation process of the display image library. After obtaining the display content in video format, the image information is extracted to obtain an image sequence. It can be understood that the amount of data in this image sequence is very large, and the difference between adjacent images is not too big. In layman's terms, there will be many frames of images corresponding to one second of video. In this second, two actors may be talking, their background will hardly change, and the color value of the image will also change very little. Therefore, the image of this one second can be simplified into a single image.

[0083] Specifically, the basis for simplification is the overlap degree. If the overlap degree of adjacent images reaches an overlap degree threshold, they can be removed, which can make the display image library smaller and more precise.

[0084] Figure 3 The second sub-flow chart of the screen display control method of the wearable device, wherein the step of determining the sampling point according to the display image library includes steps S201 to S206:

[0085] Step S201: sequentially reading display images in the display image library, traversing each pixel of the display image, and obtaining a color value of each pixel;

[0086] Step S202: inputting the color value into a trained statistical model to obtain a characteristic value of a displayed image;

[0087] Step S203: Counting the eigenvalues ​​corresponding to each displayed image to obtain an eigenvalue group;

[0088] Step S204: converting the feature value group into a feature image according to a preset filling relationship;

[0089] Step S205: performing inflection point recognition on the feature image, and marking feature values ​​according to the inflection point recognition results;

[0090] Step S206: reading the position information of the marked feature value in the feature value group, and determining the sampling point according to the position information.

[0091] The above content is a further refinement on the display image library. After the image elimination process, the display images in the display image library are relatively important. However, the difference between these display images may not be particularly obvious, and the final effect of the technical solution of the present invention is to adjust the screen brightness. Too many times of adjusting the screen brightness will affect the user experience. Therefore, it is necessary to further optimize the optimized display image library. The optimization method is to generate a feature value corresponding to these display images, analyze these values, and determine some points with higher differences.

[0092] The way to analyze these values ​​is: determine the coordinate points based on these values, generate a feature image based on these coordinate points, and the feature image is mostly a function image generated by the list-plotting method; identify the inflection points in the feature image, and then determine some important nodes with adjustment value, which are the above-mentioned sampling points.

[0093] Figure 4 The third sub-flow diagram of the screen display control method of the wearable device is as follows: the steps of reading the image in the display image library based on the sampling point, generating a corrected brightness according to the read image, and obtaining a corrected brightness array corresponding to the image library include:

[0094] Step S207: reading the feature value group corresponding to the display image library, reading the feature values ​​in the feature value group according to the sampling points, and obtaining a target value group; the target value group is a subset of the feature value group;

[0095] Step S208: calculating the feature mean of the target value group, reading the feature values ​​in the target value group in sequence, and calculating the deviation rate according to the read feature values ​​and the feature mean;

[0096] In this embodiment, the total number of the above sampling points is N , the serial number of each sampling point is n , The eigenvalues ​​in the target value group are expressed as .in, Indicates the target value group n The eigenvalues ​​corresponding to the sampling points.

[0097] Furthermore, the calculation formula of the characteristic mean of the target value group is expressed as:

[0098]

[0099] in, Represents the characteristic mean of the target value group.

[0100] Furthermore, the calculation formula of the offset rate is expressed as:

[0101]

[0102] in, Indicates the target value group n The deviation rate corresponding to the sampling points.

[0103] Step S209: reading a preset reference brightness, calculating a corrected brightness according to the offset rate and the reference brightness, and obtaining a corrected brightness array.

[0104] As mentioned above, after calculating the n The offset rate corresponding to the sampling points Afterwards, the calculation formula for the corrected brightness is expressed as follows according to the reference brightness:

[0105] ;

[0106] in, Indicates n The corrected brightness corresponding to the sampling points is represents the first correction coefficient, represents the second correction coefficient, represents the offset rate threshold, Indicates the reference brightness.

[0107] It should be noted that, in this embodiment, it can be calculated that n The corrected brightness corresponding to each sampling point is shown in FIG.

[0108] The sampling points are key nodes. By reading the characteristic values ​​corresponding to the displayed images at these key nodes, an array can be obtained. It can be considered that the mean of this array corresponds to the reference brightness. If there is a deviation between the data and the mean, the reference brightness needs to be adjusted. The specific adjustment amount is determined by the rules pre-set by the staff; the specific adjustment amount can be counted as a corrected brightness array.

[0109] Figure 5 The fourth sub-flow chart of the screen display control method of the wearable device, wherein the step of receiving the reference brightness input by the user and determining the display brightness in real time according to the reference brightness and the modified brightness array comprises:

[0110] Step S301: receiving a user brightness setting request and opening a brightness setting port;

[0111] Step S302: receiving an adjustment signal input by a user, and determining a brightness setting value based on the adjustment signal as a reference brightness; wherein the adjustment signal includes input information, touch screen information, and voice information;

[0112] Step S303: determining display brightness in real time according to the reference brightness and the modified brightness array.

[0113] The above content describes the correction process in detail. A reference brightness is preset in the system, and the user can also adjust the reference brightness. When the reference brightness is determined, the display brightness can be determined by combining the reference brightness and the correction brightness array with some simple calculations.

[0114] It should be noted that after the display brightness of the technical solution of the present invention is determined, the brightness will be adjusted only when the video is played to that point. Therefore, the time information runs through the entire text. In the initial display image library acquisition process, the time information exists as a parameter of the display image. In the subsequent image elimination process and feature value generation process, the time information needs to be transmitted and saved, and applied in the final display brightness use process.

[0115] Furthermore, the step of receiving the reference brightness input by the user also includes:

[0116] Receive the brightness adaptation request sent by the user and obtain the ambient brightness based on the preset photosensitive device;

[0117] The reference brightness is adjusted based on the ambient brightness; wherein the priority of the brightness adaptation request is lower than the brightness setting request.

[0118] In the present invention, after obtaining the ambient brightness, it is necessary to determine the corresponding ambient brightness level according to the obtained ambient brightness value. l , and then calculate the corresponding reference brightness.

[0119] The calculation formula for adjusting the reference brightness based on the ambient brightness is expressed as:

[0120] ;

[0121] in, represents the original reference brightness, represents the third correction coefficient, Indicates the ambient brightness level.

[0122] For some users with obsessive-compulsive disorder, the process of setting the reference brightness is very difficult, and they always feel that it is not set properly. Therefore, the technical solution of the present invention provides an adaptive adjustment method to adjust the screen brightness according to the ambient brightness. This process is applied to many mobile phones.
