Wherein, electronic equipment comprises projection output module, and projection output module is used for the output image of projection electronics.
As shown in Figure 1, the method can comprise the following steps:
Step 101: obtain the first parameter;
Wherein, the first parameter is the parameter relevant to the projected image that projection output module exports.
In actual application, the heat that receives of projection eyeglass is subject to projecting the impact of projected image that output module exports, therefore, and the calorie value that eyeglass of can being determined by the parameter that the projected image obtained with the output module that projects exports is relevant to project is received.As brightness value and/or color value that the first parameter can be projected image.
Step 102: determine the first calorie value that projection eyeglass receives based on the first parameter;
Concrete, the first corresponding relation of the different calorie values that different parameters receives from projection eyeglass can be previously stored with in electronic equipment, therefore, first calorie value corresponding with the first parameter can be searched based on the first corresponding relation.
Step 103: to determine to project the deformation quantity of eyeglass of projecting in output module based on the first calorie value;
Wherein, the deformation quantity of projection eyeglass can have influence on the definition of the projected image that projection output module exports, and when the first calorie value that the eyeglass that projects receives is different, the deformation quantity that projection eyeglass occurs is also different, therefore, need to determine to project the deformation quantity of eyeglass of projecting in output module based on the first calorie value.Concrete, the second corresponding relation of the different deformation amount of different first calorie value and projection eyeglass can be previously stored with in electronic equipment, this second corresponding relation can be drawn by great many of experiments in advance, after determining the first calorie value, the deformation quantity corresponding with the first calorie value can be searched based on second for relation.
Step 104: determine the first focal length based on deformation quantity;
Deformation quantity causes the definition of projected image to change, and so, can redefine the focal length that projection output module exports projected image, this first focal length is the projection focal length that projection output module exports projected image.
If the eyeglass that projects is convex lens, deformation quantity embodiments is that the thickness of convex lens becomes large, accordingly, the focal length of convex lens is caused to diminish because thickness becomes conference, thus the definition of projected image is reduced, so, the first focal length can be determined improve that projection output module exports the projection focal length of projected image based on deformation quantity, thus improve the definition of the final projected image exported.
It should be noted that, the 3rd corresponding relation of different deformation amount and different first focal length value can be previously stored with in electronic equipment, 3rd corresponding relation can be drawn by great many of experiments in advance, after determining deformation quantity, first focal length corresponding with deformation quantity can be searched based on the 3rd corresponding relation.
Step 105: be the first focal length from the second Focussing by the projection focal length of projection output module.
Wherein, projection output module utilizes the projected image of the first focal length projection to have the first definition, and projection output module utilizes the projected image of the second focal length projection to have the second definition, because the first definition is higher than the second definition, this improves the definition of projected image.
In embodiments of the present invention, to determine to project the first calorie value that eyeglass receives by obtaining the first parameter relevant with the projected image that exports of output module that projects, thus to determine to project the deformation quantity of eyeglass of projecting in output module based on this first calorie value, and then determine the first focal length based on deformation quantity, making it possible to the projection focal length of projection output module is the first focal length from the second Focussing, because projection output module utilizes the definition of the projected image of the first focal length projection to utilize the definition of the projected image of the second focal length projection higher than projection output module, therefore, the present invention can change the impact of heat build-up on projected image by the mode of adjusting focal length, compared with prior art, without the need to additionally taking electronic device space, favourable electronic equipment is towards lightening future development.

It should be noted that, projection duration can have influence on the heat dissipation capacity of electronic equipment, concrete, and when the duration that projects is shorter, the heat dissipation capacity of electronic equipment is more, and accordingly, the first calorie value that projection eyeglass receives is just less; And As time goes on, when projection time increases gradually, heat can push away long-pending gradually in electronic equipment, thus cause electronic equipment to be not easy heat radiation, namely heat dissipation capacity reduces gradually, and accordingly, the first calorie value that projection eyeglass receives will increase.
Step 203: determine the first calorie value that projection eyeglass receives based on the first parameter and projection duration;
Wherein, determine that the mode of the first calorie value that projection eyeglass receives has multiple based on the first parameter and projection duration, as a kind of implementation, the first corresponding relation prestored in electronic equipment is specifically as follows the first parameter, projection duration and the first calorie value corresponding relation, therefore, based on the first corresponding relation, first calorie value corresponding with the first parameter and the duration that projects can be searched;
And act on another kind of implementation, the caloric value of calculating electronic equipment can be carried out according to the first parameter, according to the heat dissipation capacity of projection duration determination electronic equipment, then the difference of caloric value and heat dissipation capacity is the first calorie value that the eyeglass that projects receives.That is, caloric value and first parameter of electronic equipment have direct relation, and concrete account form can be determined through great many of experiments in advance, and prestore in the electronic device; Projection time and heat dissipation capacity also have direct relation, and concrete determination mode also can be determined through great many of experiments in advance, and prestores in the electronic device.

In actual applications, the material of projection eyeglass is not quite similar, and material is related to the temperature capability of projection eyeglass, and that is, the influence degree of same calorie value to the projection eyeglass of unlike material is not identical.
Based on this, further embodiment of this invention also discloses a kind of method for controlling projection, and as shown in Figure 3, the method can comprise the following steps:
Step 301: obtain the first parameter;
Wherein, the first parameter is the parameter relevant to the projected image that projection output module exports.
Step 302: determine the first calorie value that projection eyeglass receives based on the first parameter;
Wherein, can also comprise before step 302: determine to project output module from project to the projection duration of current time; Accordingly, step 302 is specially and determines based on the first parameter and projection duration the first calorie value that projection eyeglass receives.
Step 303: determine the first material forming projection eyeglass;
The material mark forming the first material of the projection eyeglass of current use can store in the electronic device by user in advance, makes electronic equipment can determine the first material forming projection eyeglass.
This material mark can for representing the words identification of the first material or letter mark or the mark of other types, the material of the projection eyeglass of use as current in electronic equipment is glass, so, the words identification of " glass lens " can prestore in the electronic device by user in advance, makes electronic equipment can get the mark of this " glass lens ".
It should be noted that, the priority execution sequence of step 303 and step 301 ~ 302 does not limit, as first performed step 303, perform step 301,302 again in the present invention.
Step 304: to determine to project the deformation quantity of eyeglass of projecting in output module based on the first calorie value and the first material;
The temperature capability of the projection eyeglass that material is different is different, if the temperature capability of glass lens is lower than the temperature capability of resin lens, so, if glass lens and resin lens all receive same calorie value, the deformation quantity of glass lens will be greater than the deformation quantity of resin lens.
In order to determine the deformation quantity of the projection eyeglass of the current use of electronic equipment, the second corresponding relation that electronic equipment prestores is specifically as follows the corresponding relation of the first calorie value, the first material and deformation quantity, therefore, based on the second corresponding relation, the deformation quantity corresponding with the first calorie value and the first material can be searched.
Certainly, as another kind of implementation, can calculate in projection output module the deformation quantity of the eyeglass that projects according to the first calorie value and the first material, and concrete calculating rule can be determined through great many of experiments in advance according to the difference of the first material, and prestore in the electronic device.
Step 305: determine the first focal length based on deformation quantity;
