It should be noted that the device embodiment and the method embodiment belong to the same concept, and specific implementation processes thereof are described in detail in the method embodiment, and technical features in the method embodiment are correspondingly applicable in the device embodiment, which is not described herein again.
The technical solution of the present invention is further described in detail with reference to the following examples.
Please refer to fig. 5.
The embodiment of the invention provides a method for compensating screen facula, which is applied to a mobile terminal and comprises the following steps:
and step S501, determining the position of the light source through the camera.
And step S502, determining the eye position of the user through the camera.
Step S503, calculating a refraction angle formed by the light source position and the user eyes according to the light source position and the user eyes position, and determining the spot position.
Please refer to fig. 6. Generally, any two emitted light rays are reflected by the plane mirror and then enter the user's eye. The user's eyes see the intersection point of the two lines from the opposite extension lines of the object lines along the two lights, namely, the image seen in the plane mirror, and at this time, the incident angle and the reflection angle are the same, so that the user's eyes can see the object on the plane mirror only when the user's eyes are positioned on the reflected light line of the reflection angle, and cannot see the object if the user's eyes are not positioned on the reflected light line. However, the environment where the user is currently located, for example, light sources such as light and sun, are larger than the mobile terminal, so that the surface of the whole mobile terminal is equivalent to a mirror surface and is subjected to mirror reflection, but due to the visual angle of the eyes of the user (the visual angle of both eyes is usually 124 degrees), the distance from the eyes of the user to the mobile screen is different, the area of the light spots is different, the viewing angle is different, and the position of the light spots is also different. When the near-sighted light spots of the mobile terminal screen in a user become small (because the angle of a visual angle becomes small, the viewed reflecting surface of the mobile terminal becomes relatively small, at the moment, the image formed by reflection also becomes small), when two eyes see different positions for observation, the positions of the light spots are different, so the terminal determines a light source position E point through a camera, then determines a human eye position F point through the camera, and sets the mobile terminal screen as O, so as to find a [ < GOE ] angle bisector N (namely a normal), because two lines determine one plane (incident light EO and reflected light FO), the position of the light spot O is determined on the plane, the position of the light source is relatively fixed, so the mobile terminal only needs to determine the position of the eyes of the user through the camera along with the back-and forth movement of the eyes F of the user, and only needs to calculate the angle bisector (normal) and a vertical line NO of the mobile terminal on the plane of the EOF in real time, even if the user holds the mobile terminal not absolutely level, the camera is integrated with the mobile terminal, the mobile terminal is not level, the camera is also not level, so the position is the same as that in the level, namely, the mobile terminal can identify the relative position of the eyes of the user and the light source through the camera to determine the position of the light spot O point, and the position (light spot position) of the intersection point O with the screen can be rapidly calculated no matter where the user verifies the position.
Step S504, acquiring different distances from a screen of the mobile terminal when a user is at different positions of the mobile terminal through an infrared sensor, and determining current light spot outlines on the screen of the mobile terminal corresponding to the different distances; wherein the determining the current light spot profile on the mobile terminal screen corresponding to the different distances comprises guiding the user to draw a record of the current light spot profile seen on the mobile terminal screen corresponding to the different distances.
And step S505, calculating the scaling of the distance and the light spot profile, namely the user visual scale according to the collected different distance data and the corresponding light spot profile data.
And S506, determining the size of the light spot area according to the distance from the eyes of the user to the screen of the mobile terminal and the visual proportion of the user.
After the position of the light spot is determined, the area size of the light spot is also determined. Since the viewing angle of the eyes of the user is 124 degrees, the size of the light spot is different when the distance is different. Firstly, drawing a currently seen spot profile on a screen of a mobile terminal at different positions from the mobile terminal by a user, for example, placing the mobile terminal under a fixed light source, prompting the user to draw the spot profile seen at the farthest position of an arm on the screen by the mobile terminal, at this time, the mobile terminal determines the farthest distance S of the mobile terminal from the face of the user through an infrared sensor (because a single arm spread is the farthest position where the user can hold the mobile terminal), equally divides the distance S into 6 equal parts with the same length, S, S1, S2, S3, S4 and S5, the mobile terminal starts to guide the user to draw the spot profile seen at S1, the spot profile at S2, the spot profile at S3, the spot profile at S4 and the spot profile at S5 respectively, calculates the scaling ratio of the distance to the spot profile (spot area corresponding to each 1 centimeter) (namely, the user visual ratio) through data acquisition, then, at this time, the mobile terminal can calculate the size of the spot area as long as the mobile terminal recognizes the distance from the eyes of the user to the screen of the mobile terminal.
Step S507, determining the state of a reflection point formed on the screen of the mobile terminal by the light spot according to the position of the light spot and the area of the light spot; wherein the reflection point state comprises a reflection shape formed by the light spot on the screen of the mobile terminal.
Since the mobile terminal screen resembles a smooth mirror, what the shape of the light source is, and what the shape of its spot on the mobile terminal screen is, the state of the reflection point formed on said mobile terminal screen by said spot can be determined.
Step S508, performing local compensation on the light spot according to the state of the reflection point, including:
and performing local compensation according to the state of the reflection point, and performing light compensation on the area where the reflection point is located, so that the brightness of the area where the reflection point is located is consistent with the brightness of other screens of the mobile terminal, and thus the whole screen can be seen clearly.
