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.
Fig. 1 is a schematic flow chart of a method for setting a font in an embodiment of the present invention, and as shown in fig. 1, the method may be applied to a terminal, and may include the following steps:
step 101: detecting the lens in the terminal target area to obtain the degree of the lens in the target area;

step 103: and setting the font size of the terminal as the font size corresponding to the degree of the lens in the target area.
The technical scheme provided by the embodiment of the invention comprises the following steps: detecting the lens in the terminal target area to obtain the degree of the lens in the target area; determining the font size corresponding to the degree of the lens in the target area according to the degree of the lens in the target area and the relationship between the pre-stored degree and the font size; and the font size of the terminal is set to be the font size corresponding to the degree of the lens in the target area, so that the short-sighted or long-sighted user is helped to quickly set the font of the terminal.
The following describes the scheme provided by the embodiment of the present invention in detail with reference to fig. 2 to 6.
First, the above step 101 is described.
The inventor finds that: the existing scheme for determining the degree of the lens is inconvenient and low in efficiency. For example, in a lens shop, the lens power is determined based on the principle of lensometer measurement, and the operation is not convenient because the manual steps are required to adjust the distance between the lens and the observation point of the lensometer. In view of this technical problem, the inventors propose a solution for conveniently and rapidly detecting the power of the lens provided by the following embodiments.
In one embodiment, detecting the lens located in the terminal target area to obtain the power of the lens in the target area may include:
controlling a ray scanning device to scan the lens positioned in the terminal target area;
acquiring the position information of a light spot after scanning rays collected by a photosensitive plate penetrate through the lens to be refracted;
and obtaining the lens power in the target area according to the collected light spot position information and the relationship between the pre-stored light spot position information and the lens power.
In specific implementation, the step of controlling the radiation scanning device to scan the lens located in the target area of the terminal may be implemented by a radiation scanning function module in fig. 2 (i.e., a control module in the following embodiments), and the radiation scanning device may be integrated in the terminal. The step of acquiring spot position information after scanning rays collected by a photosensitive plate are refracted through the lens can be realized by the acquiring module mentioned in the following embodiments, and in particular, the spot position information can be acquired from the spot position information stored by the storage refraction point function module in fig. 2. The step of obtaining the power of the lens in the target area according to the collected spot position information and the relationship between the pre-stored spot position information and the lens power can be realized by the refraction point comparing function module and the lens power calculating function module (i.e. the power determining module described in the following embodiment) in fig. 2. The method for determining the degree of the lens is convenient and efficient.
In one embodiment, the spot position information may include: first and second spot position information;
obtaining the power of the lens in the target area according to the collected light spot position information and the relationship between the pre-stored light spot position information and the power of the lens, may include:
determining a lens power set corresponding to the first light spot position information according to the first light spot position information and a relationship between the pre-stored light spot position information and the lens power;
determining a lens power set corresponding to the second light spot position information according to the second light spot position information and a relationship between the pre-stored light spot position information and the lens power;
and determining the lens power of the lens in the target area according to the intersection of the lens power set corresponding to the first light spot position information and the lens power set corresponding to the second light spot position information.
When the method is specifically implemented, the scheme for determining the degree of the lens according to the light spot position information is convenient and high in efficiency.
An example of how to automatically detect the power of the lens is described below with reference to fig. 2 to 5.
When the glasses are fixed by the glasses fixing frame, after light rays pass through the lenses to be refracted, light spots hitting the photosensitive area of the photosensitive base plate are recorded, and the refraction angles of the areas with different thicknesses are different, so that the light spot set falling points collected by the base plate after the lenses with different degrees are refracted are different. The photosensitive bottom plate can adopt a coding format similar to a two-dimensional code or a QR code to store the position information of the light spot, the finally obtained light spot position information is compared with a light spot position information base in a database, namely, the obtained light spot position information can be input into the relationship between the pre-stored light spot position information and the lens degree for matching and searching, and the degree corresponding to the obtained light spot position information is obtained.
Specifically, each spot position information may have a power attribute, and the attribute table is shown in the following table, and the attribute table is one form of the relationship between the spot position information and the lens power, and the relationship may be in other forms, such as a model chart form and the like. In the specific determination of the powers, for example, the point a1 is included in four powers of 100 degrees, 150 degrees, 200 degrees and 250 degrees, the point B1 is included in three powers of 100 degrees, 150 degrees and 200 degrees, and the point C1 is included in two powers of 150 degrees and 250 degrees, if the position data obtained after scanning the first lens includes the point a1 and the point B1, the power of the first lens should be the intersection of the points a1 and the point B1, that is, one of 100 degrees, 150 degrees and 200 degrees, and if the position data obtained after scanning the second lens includes the point B1 and the point C1, the power of the second lens should be the intersection of the points B1 and the point C1, that is, 150 degrees. The comparison method can also shorten the comparison time compared with the traditional code comparison or pattern comparison.
Table one: refractive point attribute table
| A1 | 100 degrees, 150 degrees, 200 degrees, 250 degrees |
| B1 | 100, 150, 200 degrees |
| C1 | 150 degree, 250 degree |
| …… | …… |
And so on, for example, recording the maximum to ZZ row 1000 columns (800 degrees, 850 degrees, 900 degrees, 950 degrees, 1000 degrees).
In specific implementation, a schematic view of a lens scanning scene is shown in fig. 3; the schematic view of the refraction plane of the lens is shown in fig. 4, the scanning ray passes through the lens and strikes the photosensitive plate, and the thickness of the lens affects the refraction angle of the ray; the schematic diagram of the lens refraction plan view is shown in fig. 5, the photosensitive plate is marked with two-dimensional position information (rows and columns) by the horizontal and vertical axes, which is marked as An, the refracted ray will strike on the area of the photosensitive plate, i.e. the oval area in fig. 5, the position of each grid in the middle represents a refraction point, the same refraction point may exist in the refraction areas of lenses with different thicknesses, and the points contained in the areas formed by the lenses with different powers have overlapped parts and non-overlapped parts.
In a specific implementation, the target area may be a scanning area of the terminal.
In one embodiment, the radiation scanning device may be an infrared scanning device, a laser scanning device, or a red light scanning device.
In one embodiment, the terminal may be a cell phone, a computer, an IPAD or a precision instrument.
Next, the above step 102 is described.
The inventor also found that: when the existing terminal system is used for setting the font, the font size only has two or three fixed choices, and the font size can not completely meet the requirements of a myopia or hyperopia user. Therefore, a scheme of adjusting the font of the terminal system is proposed as follows.
In specific implementation, the relationship between the pre-stored power and the font size may be a table (a table corresponding to the lens power and the font size) shown in fig. 6. The table is flexible in setting, and can be used for setting the font sizes corresponding to a plurality of lens degrees, for example, the font sizes corresponding to 6 or more lens degrees can be set.
In specific implementation, the step of determining the font size corresponding to the power of the lens in the target area according to the power of the lens in the target area and the relationship between the pre-stored power and the font size may be implemented by the power and font size comparing function module (i.e., the determining unit 02 mentioned in the following embodiment) in fig. 2.
Third, next, the above step 103 is described.
In specific implementation, the step of "setting the font size of the terminal to the font size corresponding to the power of the lens in the target area" may be implemented by an automatic font size adjusting function module (i.e., the setting unit 03 in the following embodiment) in fig. 2. The terminal system can be an Android or IOS system, and fonts of the Android or IOS system are adjusted to be the proper size of the current user.
In specific implementation, of course, the embodiment of the present invention may also set the font color, font type, and the like according to the automatically detected lens power, and may also detect the contact lens power, and set the font quickly and conveniently according to the detected contact lens power.
Based on the same inventive concept, the embodiment of the present invention further provides a device for setting fonts, as described in the following embodiments. Because the principle of the device for setting the font to solve the problem is similar to the method for setting the font, the implementation of the device for setting the font can refer to the implementation of the method for setting the font, and repeated parts are not described again.
