Method and apparatus for self camera shooting
An apparatus capable of taking a self-portrait picture includes a screen, a camera, and a controller configured to cause the screen to display a live preview image received from the camera, after the live preview image is displayed, detect a first user gesture for triggering a display of an indicator on the screen, cause the screen to display the indicator at a changeable position where the first user gesture is detected, wherein the indicator indicates that a gesture detection mode is entered to recognize a second user gesture different from the first user gesture, while the indicator is displayed on the screen, detect the second user gesture in the indicator, and after detecting the second user gesture, cause the camera to automatically take a self-portrait picture.
1. A mobile device of a user, comprising:
a display facing a first direction;
a camera facing the first direction;
a memory; and
a processor configured to:
control the display to display a preview image of the user for a self-portrait mode received from the camera,
detect a user gesture with fingers of the user while the preview image for the self-portrait mode is displayed on the display,
in response to the detected user gesture corresponding to a pre-defined motion, control the display to display a screen comprising the preview image and a time counter indicating a remaining time until the camera takes a picture, and
upon expiration of the time counter, control the camera to automatically capture an image as a self-portrait picture of the user.
2. The mobile device of claim 1 , wherein the processor is further configured to, in response to detecting the fingers of the user, control the display to display an indicator over the preview image.
3. The mobile device of claim 2 , wherein an area defined by the indicator and an area occupied by fingers are substantially identical.
4. The mobile device of claim 2 , wherein the indicator indicates that the mobile device is ready to detect the user gesture with the fingers.
5. The mobile device of claim 2 , wherein a location of an area defined by the indicator within the display depends on a location of an area that the fingers occupy.
6. The mobile device of claim 2 , wherein the processor is further configured to display guide information over the preview image while the indicator is displayed.
7. The mobile device of claim 2 , wherein the processor is further configured to, in response to detecting the fingers of the user:
determine whether the detected fingers of the user are valid to provide the indicator, and
in case that the detected fingers of the user are valid, control the display to display the indicator over the preview image.
8. The mobile device of claim 1 , wherein the processor is further configured to activate, in response to the detected user gesture corresponding to the pre-defined motion, the time counter that expires in a preset time after the activation.
9. The mobile device of claim 1 , wherein the user gesture is designable by the user.
10. The mobile device of claim 1 , wherein the user gesture is a touchless user gesture.
11. The mobile device of claim 1 , wherein the processor is further configured to save the captured image as the self-portrait picture in the memory.
12. A method for taking a self-portrait picture at a mobile device of a user, the method comprising:
displaying, on a display of the mobile device and facing a first direction, a preview image of the user for a self-portrait mode received from a camera of the mobile device, the camera facing the first direction;
detecting a user gesture with fingers of the user while the preview image for the self-portrait mode is displayed on the display;
in response to the detected user gesture corresponding to a pre-defined motion, displaying, on the display, a screen comprising the preview image and a time counter indicating a remaining time until the camera takes a picture on the display; and
upon expiration of the time counter, automatically capturing an image as the self-portrait picture of the user using the camera.
13. The method of claim 12 , further comprising:
in response to detecting the fingers of the user, displaying an indicator over the preview image on the display.
14. The method of claim 13 , wherein an area defined by the indicator and an area occupied by fingers are substantially identical.
15. The method of claim 13 , wherein the indicator indicates that the mobile device is ready to detect the user gesture with the fingers.
16. The method of claim 13 , wherein a location of an area defined by the indicator within the display depends on a location of an area that the fingers occupy.
17. The method of claim 13 , further comprising:
displaying guide information over the preview image while the indicator is displayed.
18. The method of claim 13 , wherein displaying the indicator over the preview image on the display comprising:
in response to detecting the fingers of the user:
determining whether the detected fingers of the user are valid to provide the indicator, and
in case that the detected fingers of the user are valid, displaying the indicator over the preview image on the display.
19. The method of claim 12 , further comprising:
activating, in response to the detected user gesture corresponding to the pre-defined motion, the time counter that expires in a preset time after the activation.
20. A non-transitory computer readable storage medium comprising instructions, when executed by a processor of a mobile device of a user, configured to cause the mobile device to perform:
displaying, on a display of the mobile device, a preview image of the user for a self-portrait mode received from a camera of the mobile device;
detecting a user gesture with fingers of the user while the preview image for the self-portrait mode is displayed on the display;
in response to the detected user gesture corresponding to a pre-defined motion, displaying, on the display, a screen comprising the preview image and a time counter indicating a remaining time until the camera takes a picture on the display; and
upon expiration of the time counter, automatically capturing an image as a self-portrait picture using the camera of the user.
