Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a method for adjusting display content of a terminal, wherein the terminal can be an intelligent mobile phone or an electronic terminal such as a notebook computer and a tablet computer, and the invention is not limited to the method.
As shown in fig. 1, the method for adjusting display content of a terminal according to this embodiment includes:
s101: acquiring the distance between a user and a terminal display screen and an image formed by the terminal display screen in the eyes of the user;
s102: judging whether the parameters of the image are in the parameter range of a standard image, wherein the standard image is an image formed by a terminal display screen in the eyes of a user when the user clearly sees the display content of the display screen at the distance, if so, entering S103, and if not, entering S104;
s103: keeping the size of the display content of the terminal display screen unchanged;
s104: and adjusting the size of the display content of the display screen of the terminal so that the display content of the display screen can be clearly seen by a user.
Because the human eyes clearly see the external things based on the convex lens imaging principle, when the distance between the terminal display screen and the human eyes is different, the size and the definition of the image formed by the terminal display screen in the human eyes are different, and under the same distance, the size of the display content of the terminal display screen is different, and the size and the definition of the image formed by the terminal display screen in the human eyes are different.
Based on this, after the distance between the user and the terminal display screen is acquired, and the image formed by the terminal display screen in the eyes of the user at the distance is acquired, the parameter of the image is compared with the parameter of the standard image at the distance, and since the standard image is the image formed by the terminal display screen in the eyes of the user when the user clearly sees the display content of the display screen at the distance, it can be determined that the user can clearly see the display content of the display screen according to the comparison result.
That is, when the parameter of the image is within the parameter range of the standard image, it can be determined that the user can clearly see the display content of the display screen; when the parameters of the image are not in the parameter range of the standard image, it can be judged that the user can not clearly see the display content of the display screen, and at this time, the size of the display content of the terminal display screen can be adjusted, that is, the parameters of the image formed by the terminal display screen in the eyes of the user at the distance are adjusted to be in the parameter range of the standard image, so that the user can clearly see the display content of the display screen.
The terminal in this embodiment includes a distance sensor and a camera module (e.g., a high definition camera), where the distance sensor is used to obtain a distance between a user and a display screen of the terminal, and the camera module is used to obtain an image of the display screen of the terminal in eyes of the user.
The acquiring of the image of the terminal display screen in the eyes of the user includes:
acquiring an eye image of the user;
and extracting an image formed by the terminal display screen in the eyes of the user from the eye image.
Specifically, the camera module captures an image of the user's eyes by capturing an image of the user's face or eyes, and then the control module or the processing module in the camera module can extract an image of the terminal display screen in the user's eyes from the image of the eyes and capture parameters of the image, wherein the parameters include the size and definition of the image.
Based on this, judging whether the parameters of the image are in the range of the standard image parameters includes:
judging whether the size of the image is within the size range of the standard image or not, and judging whether the definition of the image is within the definition range of the standard image or not;
if the size of the image is within the size range of the standard image and the definition of the image is within the definition range of the standard image, the parameter of the image is within the range of the parameter of the standard image;
and if the size of the image is not in the size range of the standard image and/or the definition of the image is not in the definition range of the standard image, the parameter of the image is not in the range of the parameter of the standard image.
Of course, the invention is not limited thereto, and in other embodiments, the comparison determination may be performed by other parameters of the image, such as resolution.
In this embodiment, adjusting the size of the content displayed on the display screen of the terminal includes: and enlarging or reducing the display content of the display screen according to a certain proportion, so that the parameters of the image formed by the terminal display screen in the eyes of the user are in the parameter range of the standard image. Specifically, when the size of the image formed by the terminal display screen in the eyes of the user is smaller than that of the standard image or the definition of the image formed by the terminal display screen in the eyes of the user is smaller than that of the standard image at the distance, the display content of the display screen is enlarged according to a certain proportion; and when the size of the image formed by the terminal display screen in the eyes of the user is larger than that of the standard image or the definition of the image formed by the terminal display screen in the eyes of the user is larger than that of the standard image at the distance, reducing the display content of the display screen according to a certain proportion.
Because the focal lengths of the compound convex lenses formed by human eyes with different eyesight (including corrected eyesight) are different, when users with different eyesight are at the same distance with the display screen, the parameters of the images formed by the display content of the display screen in the human eyes are also different.
Based on this, before the terminal realizes the automatic adjustment of the size of the display content, that is, before acquiring the distance between the user and the terminal display screen and the image formed by the terminal display screen in the eyes of the user, the method further comprises the following steps: and acquiring images formed by the display screen of the terminal in the eyes of the user when the user clearly sees the display content of the display screen at different distances, and storing the images as standard images at corresponding distances.
When the standard image at any distance is acquired, a user needs to judge whether the display content of the display screen can be clearly seen according to subjective feeling, if so, an input instruction is input to acquire an image formed by the display content with the current size in eyes, the image is stored as the standard image, and if not, an adjustment instruction is manually input to adjust the size of the display content until the display content of the display screen can be clearly seen at the current distance.
Of course, it should be noted that, in this embodiment, the user may also adjust the size of the content displayed on the display screen of the terminal by manually inputting an adjustment instruction. Specifically, the user may input an automatic adjustment starting instruction to the terminal to control the terminal to enter the automatic adjustment mode, and may input an automatic adjustment closing instruction to the terminal to control the terminal to enter the automatic adjustment mode. After the terminal enters the automatic adjustment mode, the steps from S101 to S104 are executed once every certain time interval, so as to adjust the size of the display content in real time, and meanwhile, the terminal can also receive an adjustment instruction manually input by a user, so as to adjust the size of the display content. However, after the terminal exits the automatic adjustment mode, the terminal can only receive an adjustment instruction manually input by the user to adjust the size of the display content.
The method for adjusting the display content of the terminal comprises the steps of obtaining the distance between a user and a terminal display screen and an image formed by the terminal display screen in the eyes of the user, and judging whether the parameter of the image is in the parameter range of a standard image, wherein the standard image is the image formed by the terminal display screen in the eyes of the user when the user clearly sees the display content of the display screen at the distance; if so, keeping the size of the display content of the terminal display screen unchanged; if not, adjusting the size of the display content of the terminal display screen so that the user can clearly see the display content of the display screen. Based on the method and the device, the size of the display content of the display screen can be automatically adjusted according to the image formed by the display screen in the eyes of the user, so that the problems of complicated user operation and poor experience effect caused by manual adjustment can be solved.
The embodiment of the invention also provides a system for adjusting the display content of the terminal, wherein the terminal can be an intelligent mobile phone, and can also be an electronic terminal such as a notebook computer, a tablet computer and the like, and the invention is not limited to the above.
