Step S2: and determining the scene of the electronic equipment according to the position information and the brightness information.
For users with partial color blindness (partial color blindness means that partial color cannot be distinguished) or color weakness, the difference of the environment will have a great influence on the user to distinguish the color. For example, the brightness of the environment may have a large impact on users with color recognition defects. Therefore, in the present application, the position of the electronic device and the brightness information of the environment where the electronic device is located are determined, and the scene where the electronic device is located, that is, the scene where the user is located is determined according to the position information and the brightness information.
The scene where the electronic equipment is located comprises outdoor day, outdoor night, indoor day and indoor night. Of course, the scene where the electronic device is located may be further finely divided according to the location information of the electronic device and the brightness information of the environment where the electronic device is located.
As one mode, the electronic device obtains position information and brightness information of the environment by using a positioning device and a brightness detection device configured by the electronic device. As another mode, the electronic device receives position information and brightness information of an environment where the electronic device is located, which are transmitted by another electronic device. Wherein both electronic devices are carried with the user.
Step S3: a color replacement model corresponding to the scene is obtained, the color replacement model comprising a correspondence of the original color to the replacement color.

Wherein the original color refers to the true color of the environment image, and the replacement color is the color that needs to be presented to the user with the color recognition defect. For example: one corresponding relation in the color replacement model is as follows: color 1 (original color) corresponds to color 2 (alternate color), and if an object in the environment is color 1, then the image of the object that is ultimately presented to the user is color 2.
It should be noted here that, according to the specific color identification defect of the user, color replacement models in different scenes need to be respectively constructed for the user of this type. For example: the user who is blind with red cannot distinguish red and dark green, and cannot distinguish blue, purple and purple, so that in the color replacement model for the user, the replacement color corresponding to red and dark green needs to be set as other two different colors that the user can recognize, and the replacement color corresponding to blue, purple and purple needs to be set as other three different colors that the user can recognize. In implementation, a color replacement model can be quickly constructed based on the LUV color space.

And according to the color replacement model corresponding to the current scene, determining a replacement color corresponding to the original color in the obtained first image, and performing color adjustment on the image area in the first image based on the replacement color to generate a second image. For example: a region in the first image is color 1 and the color presented to the user in the second image is color 2 (an alternative color corresponding to color 1).
Step S7: a second image is shown.
As one way, the electronic device presents the second image through its own display device. As another way, the electronic device projects the second image to an external space for presentation. Alternatively, the electronic device transmits the second image to another electronic device, which displays the second image.
According to the control method, the electronic device determines a scene according to the position information and the brightness information of the environment, a color replacement model corresponding to the current scene is obtained from a pre-constructed color replacement model, the electronic device obtains a first image of a target area, a replacement color corresponding to an original color in the first image is determined according to the color replacement model, then color adjustment is carried out on an image area in the first image based on the replacement color, and a second image is generated and displayed. It can be seen that, in the control method disclosed in the present application, the color of the first image in the target region is adjusted by using the color replacement model corresponding to the current scene, so that the corresponding replacement color is presented to the second image displayed to the user, and by reasonably configuring the corresponding relationship between the original color and the replacement color in the color replacement model, the user can distinguish multiple colors with identification defects, thereby improving the color distinguishing ability of the user and reducing the inconvenience of the user.
