Mobile terminal includes black and white sensor photographic head and color sensor photographic head, and the method specifically may include steps of:
Step 201, the monochrome information of monitoring photographed scene.
Wherein, when using mobile terminal shooting photo, can initially enter shooting preview interface, then monitoring is current claps
Take the photograph the brightness value under scene.
Step 202, makes comparisons described monochrome information with the second luminance threshold, obtains the second comparative result.
Wherein, first this brightness value is compared with bigger luminance threshold, thus judge that present filming scene is place
In the environment (such as, outdoor environment) that the relatively low environment (such as, indoor environment) of luminosity or luminosity are higher, preset here
The second luminance threshold be 50 luxs (Lux).
Then, after obtaining the second comparative result, it is possible to according to described second comparative result, determine described target image
