Apparatus and method for controlling picture using image recognition
View Patent ↗A picture control apparatus provides control of a picture displayed on a display of a mobile terminal according to an action detected through image recognition. A picture control method includes detecting an action from images captured by a camera, and controlling a picture displayed on a display if the detected action is a specific action.
1. A picture control apparatus, comprising:
a display to display a picture and to receive a touch corresponding to a location on the display;
a driver to drive a camera to capture images for action detection;
an action detector to detect a specific action from the images captured by the camera; and
a picture controller configured to control the picture displayed on the display in association with the location on the display if the specific action is detected by the action detector.
2. The picture control apparatus of claim 1 , wherein the picture controller enlarges or reduces a size of the picture.
3. The picture control apparatus of claim 1 , wherein the picture controller enlarges or reduces a size of an entire or partial area of the picture, the picture corresponding to a single-layered picture.
4. The picture control apparatus of claim 2 , wherein the picture controller enlarges or reduces a size of a layer of the picture, the picture corresponding to a multi-layered picture.
5. The picture control apparatus of claim 2 , wherein the picture controller enlarges or reduces a size of an object in the picture, the picture corresponding to a tree-structured picture comprising a plurality of objects.
6. The picture control apparatus of claim 2 , wherein the picture controller enlarges or reduces a size of the picture stored in a memory.
7. The picture control apparatus of claim 2 , wherein the picture controller enlarges or reduces a size of the picture transmitted through a network.
8. The picture control apparatus of claim 1 , wherein the driver is configured to drive a picture control function in response to the touch on a touch screen of the display.
9. The picture control apparatus of claim 8 , wherein the picture controller enlarges or reduces a size of the picture and centers the picture at the location where the touch has occurred on the touch screen.
10. The picture control apparatus of claim 1 , further comprising an action setting unit to set the specific action that is detected by the action detector.
11. The picture control apparatus of claim 1 , further comprising a sound controller to control sound associated with the picture according to the specific action detected by the action detector.
12. The picture control apparatus of claim 1 , wherein the action detector detects a movement toward or away from the camera from the images.
13. The picture control apparatus of claim 1 , wherein the action detector detects a movement to the left or to the right from the images.
14. The picture control apparatus of claim 1 , wherein the action detector detects a wink of a left eye or a right eye from the images.
15. The picture control apparatus of claim 1 , wherein the action detector detects a lip shape from the images.
16. The picture control apparatus of claim 1 , wherein the action detector detects an inclination of a face towards or away from the camera from the images.
17. The picture control apparatus of claim 1 , wherein the action detector detects a rotation of a face to the left or right from the images.
18. The picture control apparatus of claim 1 , wherein the action detector detects a grimace of a face from the images.
19. A picture control method comprising:
displaying a picture on a display and receiving a touch corresponding to a location on the display;
driving a camera to capture images for action detection;
detecting an action from the images captured by the camera; and
controlling the picture displayed on the display in association with the location on the display if the detected action is a specific action.
20. The picture control method of claim 19 , further comprising:
receiving a driving command to detect the action.
21. The picture control method of claim 19 , further comprising:
terminating the detecting and the controlling if an end command is received.
22. The picture control method of claim 19 , wherein the specific action is a variation in motion or a variation in a facial expression.
23. The picture control method of claim 19 , further comprising:
adjusting a degree of enlargement or reduction of the picture in accordance with a speed or a number of the specific action.
