The embodiments of using color, brightness and pattern respectively are as the following.
 
1. An Embodiment of Using Color
 
     The user presets a color value as base color and the user sets positive and negative tolerance simultaneously; a color represented by a color value which is in the range of positive and negative tolerance is trigger color. When the camera module  110  capturing an image, the camera module  110  divides the image into units of n×n pixels (number of pixels can be equal to the resolution of the camera module  110  or less than the pixels thereof; In case that the number of pixels is less than the resolution, the color value of each unit is equal to average value of color values of all actual pixels in the unit), if the proportion for the number of pixel units of which color values are in the range of tolerance in total number of all pixel units exceeds a preset value (for example, including but not limited to, 80%, which can be set according to actual situation), it is regarded as satisfying trigger color, i.e. the preset image is captured. 
     2. An Embodiment of Using Brightness 
     The user presets a brightness value as base brightness and the user sets positive and negative tolerance simultaneously; an brightness represented by a brightness value which in the range of positive and negative tolerance is preset color. When the camera module  110  capturing an image, the camera module  110  divides the image into units of n×n pixels (number of pixels can be equal to resolution of the camera module  110  or less than the pixels thereof; in case that the number of pixels is less than the resolution, the brightness value of each unit is equal to average value of brightness values of all actual pixels in the unit), if the proportion for the number of pixel units of which brightness values are in the range of tolerance in total number of all pixel units exceeds a preset value (for example, including but not limited to, 80%, which can be set according to actual situation), it is regarded as satisfying trigger brightness, i.e. the preset image is captured. 
     3. An Embodiment of Using Pattern 
     The user draws an outline as trigger pattern, the outline can be unclosed. When the camera module  110  capturing an image, the camera module  110  will detect the object in the image (if required, including that, but not limited to, detection is made in situations of different focuses; the detection can determine the edge line of the object according to color contrast value) so as to compare the detected edge line of the object with the trigger pattern, if they are matched, the trigger pattern is satisfied, i.e. the preset image is captured. 
     Of course, the above three embodiments serve to exemplary illustration; any method for identifying color, brightness, pattern of an image is adaptable. 
     In addition, a set password can be text or pattern; the password entering interface is shown by  FIG. 2  and  FIG. 3 ;  FIG. 2  is a text entering interface;  FIG. 3  is a pattern entering interface; the pattern can be made up by connecting dots; of course, it can be a combination of text and pattern.
