Below in conjunction with accompanying drawing, the action that the mobile terminal of take is identified respectively " taking pictures " and " abandoning taking pictures " as touch-screen mobile phone as Application Example to the present invention is elaborated:
Realize " focus-take pictures " function
1, focus operation: see also Fig. 4 and Fig. 5, wherein, in Fig. 4 Fingers to circle be the key touch area of taking pictures, four-headed arrow represents the finger direction vertically pressing and leave; Fig. 5 touches action recognition process schematic diagram for pointing with the key touch area of taking pictures.
When user's finger is by as far as closely pressing when taking pictures key touch area, finger is ascending with touch-screen contact area, now baseband processor is gradient to D(n by driving chip to obtain touching area data by D (0)), this testing process is fixed as very first time section T1; Within the section T1 time very first time, if D (n)≤D (n-1), wherein, n≤1, baseband processor identification touch action is vertical close action, as the curved portion on the left side in Fig. 5; In the second time period T2 after this, baseband processor is controlled camera focusing by focusing control unit, as the mid portion of Fig. 5 curve.
2, the action of taking pictures: after the second time period T2 finishes, in the 3rd time period T3, if finger is descending with touch-screen contact area, represent that finger leaves touch-screen, baseband processor drives chip to obtain touching area data by D(0 by touch-screen) be gradient to D(n), this testing process is fixed as the 3rd time period T3; Within the 3rd time period T3 time, if D (n)≤D (n-1), n≤1, is identified as vertical departure motion; After the 3rd time period T3 time, baseband processor is controlled camera by the control unit of taking pictures and is taken pictures.
Realize " focus-abandon and take pictures " function
See also Fig. 6 and Fig. 7, wherein, in Fig. 6 Fingers to circle be the key touch area of taking pictures, four-headed arrow represents that finger is outwards marked the direction of time action by the key Petting Area of taking pictures; Fig. 7 touches action recognition process schematic diagram for pointing with the key touch area of taking pictures.
Finger is pressed in the touch area of the key of taking pictures, the area that finger contacts with touch-screen is ascending, this testing process is fixed as very first time section T1, the corresponding order of taking pictures of this action, when pointing the area contacting with touch-screen, after maximum, can continue the second time period T2, this process is focus process, if will abandoning taking pictures, user returns to preview mode, finger outwards marks on the key touch area of taking pictures, the slip touch gestures that forms one " yi word pattern " away from the key touch area of taking pictures, be the 3rd time period T3 the detection time of this action; Within the 3rd time period, finger may change with touch-screen contact area, but changes not quite, can realize with general slip Gesture Recognition Algorithm; Then, after the 3rd time period T3 time, baseband processor is controlled camera by preview control unit and is turned back to preview mode.
It should be noted that described very first time section T1, the second time period T2 and the 3rd time period T3 can adjust length according to actual conditions.
In sum, a kind of mobile terminal and its implementation with functions of camera shutter provided by the invention, it is by detecting touch action and touch information by touch screen module, and touch action and touch information are sent to baseband processor, by baseband processor, identify described touch action and touch information afterwards, and according to described touch action corresponding execution take pictures action or the action of abandoning taking pictures, and this process realizes by user's touch gestures, thereby realized the function of being controlled the time for exposure of mobile terminal by user oneself, convenient for users, improved user's experience.
Be understandable that, for those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the present invention.
