Referring to Fig. 1, for taking the main flow process of frame per second method of adjustment in the embodiment of the present invention, described method can be applied to one to be had in the electronic equipment of image unit.The main flow process of described method is as follows:

Step 101: described image unit is taken with the first frame per second, obtains the first image information, and the frame per second of described the first image information is the first frame per second.

First described image unit is taken with described the first frame per second, can obtain described the first image information.For example, can obtain the first image information described in a frame, the first image information also can be called the first frame image information described in this frame.The frame per second of described the first image information can be the first frame per second.

Step 102: judge whether described the first image information meets default shooting frame per second regularization condition.

Obtaining after described the first image information, can judge whether described the first image information meets default described shooting frame per second regularization condition.

In the embodiment of the present invention, described shooting frame per second regularization condition can preset.Described shooting frame per second regularization condition, can comprise the condition that when shooting frame per second should be heightened, also can comprise the condition that when shooting frame per second should be turned down.

The condition that shooting frame per second is heightened can have multiple, for example, a kind of possible described shooting frame per second regularization condition (condition that shooting frame per second is heightened) can be: described the first image information obtaining and the front M frame image information obtaining are before contrasted, the percent value that the pixel changing in described the first image information accounts for total pixel in a frame image information is not less than the first default percent value, and M is positive integer.

For example, described the first image information and front the first image information of obtaining before can be contrasted, or described the first image information and front the second frame image information obtaining before can be contrasted, or described the first image information and the front M frame image information obtaining before can be contrasted.In a word, only need from the image information of obtaining before, select a frame image information to come to contrast with described the first image information, only need contrast once.

Or, another kind of possible described shooting frame per second regularization condition (condition that shooting frame per second is heightened) can be: described the first image information obtaining and the front L frame image information obtaining are before contrasted respectively, with described front L frame image information in P frame image information while contrasting, the percent value that the pixel changing in described the first image information accounts for the total pixel of a frame image information is all not less than the described first default percent value, L is positive integer, and P is the integer that is not less than L.

For example, described the first image information and front the first image information and front the 3rd frame image information that obtain before can be contrasted respectively, or described the first image information and front the second frame image information, front the 3rd frame image information and front the 4th frame image information that obtain before can be contrasted respectively, or described the first image information and the front L frame image information obtaining before can be contrasted respectively.In a word, need from the image information of obtaining before, select L frame image information to come to contrast with described the first image information respectively, need to contrast L time.After L contrast, if determine described the first image information with described front L frame image information in P frame image information while contrasting, the percent value that the pixel changing in described the first image information accounts for the total pixel of a frame image information is all not less than the described first default percent value, determines that described the first image information meets described shooting frame per second regularization condition.

The condition that shooting frame per second is turned down can have multiple, for example, a kind of possible described shooting frame per second regularization condition (condition that shooting frame per second is turned down) can be: described the first image information obtaining and the front M frame image information obtaining are before contrasted, the percent value that the pixel changing in described the first image information accounts for total pixel in a frame image information is not more than the second default percent value, and M is positive integer.

Or, another kind of possible described shooting frame per second regularization condition (condition that shooting frame per second is turned down) is: described the first image information obtaining and the front L frame image information obtaining are before contrasted respectively, with described front L frame image information in P frame image information while contrasting, the percent value that the pixel changing in described the first image information accounts for the total pixel of a frame image information is all not more than the described second default percent value, L is positive integer, and P is the integer that is not less than L.

For example, described the first image information and front the second frame image information and front the 3rd frame image information that obtain before can be contrasted respectively, or described the first image information and front the first image information, front the 3rd frame image information and front the 4th frame image information that obtain before can be contrasted respectively, or described the first image information and the front L frame image information obtaining before can be contrasted respectively.In a word, need from the image information of obtaining before, select L frame image information to come to contrast with described the first image information respectively, need to contrast L time.After L contrast, if determine described the first image information with described front L frame image information in P frame image information while contrasting, the percent value that the pixel changing in described the first image information accounts for the total pixel of a frame image information is all not more than the described second default percent value, determines that described the first image information meets described shooting frame per second regularization condition.
