The invention is described below by means of specific examples.
Referring to fig. 1, fig. 1 is a hardware architecture diagram of a display device, where the display device includes a display 100, a camera 101 and a face recognition chip; the camera 101 is installed on the display 100 and used for collecting face data in front of the display 100 and sending the face data to the face recognition chip; the face recognition chip analyzes and processes the received face data and actively recognizes the face, then communicates with the Scalar chip 102 of the display 100, and the Scalar chip 102 of the display 100 controls the signal of the display 100 and outputs the image.
In this embodiment, the camera 101 is a wide-angle camera, and the wide-angle camera is installed at the center of the top of the display surface of the display 100. The wide-angle camera has the advantages that the visual angle of the lens is large, the visual field is wide, and the range of the scenery observed from a certain viewpoint is much larger than that of the scenery observed by human eyes at the same viewpoint; the scene is long, and a quite large clear range can be shown, which is beneficial to the subsequent face recognition processing of the face recognition chip. Preferably, the face recognition chip is an AI chip, because the AI chip has the capability of handling a large number of computational tasks in artificial intelligence applications, and therefore, face recognition can be made more accurate with this.
In the above display device, the display 100 may be a display available on the market, such as the liquid crystal display 100, and the camera 101 may be the camera 101 carried by the display 100 or the independent camera 101.
An embodiment of the present invention further provides a method for adjusting the personalized display effect of the display device, please refer to fig. 2, where the method includes the following steps:
s10, acquiring a current image stream in front of the display 100 through the camera 101, and executing S20;
s20, 103, identifying the current face feature from the two-dimensional image information of the current image stream, and executing S30;
s30, judging whether the current face features are consistent with the face features of the last time, if so, executing a step S40, and if not, executing a step S50;
s40, the current display effect of the display 100 is maintained
And S50, controlling the display 100 to display the display effect bound with the current human face feature.
Further, referring to fig. 3, step S50 specifically includes the following steps:
s501, inquiring a face feature library, and executing S502 in the next step;
s502, judging whether the face features matched with the current face features exist in the face feature library, if so, executing a step S504, and if not, executing a step S503;
s503, binding display characteristic data of the current display 100 with the current human face characteristic, wherein the display characteristic data comprises contrast of the display 100, maximum brightness of the display 100, minimum brightness of the display 100, gamma curve of the display 100, color temperature curve of the display 100 and ambient brightness of the display 100;
s504, calling display feature data bound with the matched human face features, and executing the step S505;
s505, automatically changing the display effect of the current display 100 into the display effect which is consistent with the display characteristic data, and executing the step S506;
s506, judging whether the display effect of the current display 100 is artificially changed, if so, executing a step S507, otherwise, executing a step S505;
and S507, updating the display characteristic data matched with the current face characteristics into display characteristic data corresponding to the changed display effect.
Specifically, after the display 100 is powered on, power can be supplied to the camera 101, the camera 101 provides the current image stream to the AI chip, the AI chip intelligently identifies the characteristics of the current face from the two-dimensional image information of the current image flow, firstly judges whether the characteristics of the current face are consistent with the characteristics of the previous face, if they are consistent, they belong to the same person, then no automatic adjustment of the display effect of the display 100 is currently made, and when a discrepancy with the previous human face features is detected, it indicates that the person currently using the display 100 has changed, and then matches the current facial features with the facial features in the chip library, when the matched face data exists in the face feature library, the display feature data bound with the current face features is called, thereby causing the display 100 to automatically display a display effect that corresponds to the display characteristic data. When the face data matched with the face data does not exist in the face feature library, the display 100 does not change the display effect, the current state is kept, and meanwhile, the feature information of the current face is bound and associated with the effect of the current display 100 and is stored. When the user adjusts the display characteristics of the display 100, the display characteristic data bound to the current face characteristic is automatically updated.
In summary, the present invention uses the camera 101 in combination with the face recognition chip to quickly and accurately determine the face data of the user of the display 100, so as to automatically adjust the display effect of the display 100 according to the habits of different people, so as to multiplex the display 100 for multiple people and maintain the display characteristics related to the user, so as to achieve the optimal display effect, and provide a friendly solution for the personalized use of the display 100.
The technical contents of the present invention are further illustrated by the examples only for the convenience of the reader, but the embodiments of the present invention are not limited thereto, and any technical extension or re-creation based on the present invention is protected by the present invention. The protection scope of the invention is subject to the claims.
