Long by certain image-region in current preview screen;

Obtain the brightness value of described image-region, and judge whether the brightness value of described image-region is greater than default luminance threshold;

If the brightness value of described image-region is greater than default luminance threshold, be judged to be overexposure, and then adjust continuously exposure bias value to reduce exposure, press EO until long; Otherwise, be judged to be secretly, and then adjust continuously exposure bias value to increase exposure, press EO until long.

As preferably, in technique scheme, described exposure bias value comprises positive offset and the negative offset that absolute value increases successively, and described positive offset represents to increase exposure, and described negative offset represents to reduce exposure.

-3.0 ,-2.0 ,-1.0,0 as preferably, in technique scheme, described exposure bias value at least comprises: ,+1.0 ,+2.0 ,+3.0, wherein, 0 initial value for acquiescence.

As preferably, in technique scheme, the described step of adjusting continuously exposure bias value is specially: according to absolute value order from small to large, positive offset or negative offset are set.

The present invention also provides a kind of manual adjustment to improve the device of automatic exposure effect, and it comprises:

Brightness value acquisition module, in the time pressing certain image-region of current preview screen with the head of a household, obtains the brightness value of described image-region;

Whether judge module, be greater than default luminance threshold for the brightness value that judges described image-region;

Exposure compensating module, if be greater than default luminance threshold for the brightness value of described image-region, is judged to be overexposure, and then adjusts continuously exposure bias value to reduce exposure, presses EO until long; Otherwise, be judged to be secretly, and then adjust continuously exposure bias value to increase exposure, press EO until long.

As preferably, in technique scheme, described exposure bias value comprises positive offset and the negative offset that absolute value increases successively, and described positive offset represents to increase exposure, and described negative offset represents to reduce exposure.

-3.0 ,-2.0 ,-1.0,0 as preferably, in technique scheme, described exposure bias value at least comprises: ,+1.0 ,+2.0 ,+3.0, wherein, 0 initial value for acquiescence.

As preferably, in technique scheme, described exposure compensating module is positive offset or negative offset to be set to adjust exposure according to absolute value order from small to large.

Compared with prior art, beneficial effect of the present invention is:

After using the present invention, in the time that user is dissatisfied to the exposure of certain image-region in current preview screen, draw overexposure or excessively dark conclusion by long by the respective image region in preview screen with according to the brightness value after the exposure detecting, thereby carry out the exposure compensating after automatic exposure, it has not only solved over-exposed or under-exposed problem preferably, and can adjust according to actual conditions, improve the experience of camera, have advantages of easy to adjust and simple and practical.
