Abstract

A method for underwater operating a camera built in a touch input device including a touch screen, a processor, and a controller may be provided that includes: performing a first drive mode in which a touch position is detected underwater by a capacitance change amount due to a touch pressure; and controlling operation of the camera underwater according to a touch on the touch screen by an object.

Claims

1. A method for operating a camera included in a touch input device including a touch screen which includes touch position sensing electrode and touch pressure sensing electrode, the method comprising:

determining, by a processor, whether the camera is underwater or not;

detecting, by the processor, a touch position of an object on the touch screen based on a capacitance change amount using the touch position sensing electrode if the camera is not underwater;

detecting, by the processor, the touch position of the object on the touch screen based on a capacitance change amount due to the touch pressure using the touch pressure sensing electrode if the camera is underwater, the touch position being detected by;

determining a capacitance pattern for a varying capacitance throughout the touch screen when the touch screen is underwater and no touch input occurs;

resetting, by the processor, a varying reference capacitance for determining whether a touch input by the object occurs or not, the varying reference capacitance being reset based on the determined capacitance pattern when the touch screen is underwater and no touch input occurs; and

receiving, by the touch screen, the touch pressure by the object underwater; and

detecting, by the processor, the touch position on the touch screen based on the capacitance change amount due to the touch pressure and the reset varying reference capacitance; and

controlling operation of the camera according to the detected touch position by the object.

2. The method of claim 1, wherein the resetting the varying reference capacitance is performed repeatedly at a predetermined cycle.

3. The method of claim 1, wherein, the controlling the operation of the camera underwater comprises photographing by touching a shutter mark positioned on the touch screen.

4. The method of claim 3, wherein, the controlling the operation of the camera underwater comprises performing zoom-in by touching a zoom-in mark positioned on the touch screen and zoom-out by touching a zoom-out mark positioned on the touch screen.

5. The method of claim 3, wherein, the controlling the operation of the camera underwater comprises selecting a front camera mode or a rear camera mode by touching a switch mark positioned on the touch screen.

6. The method of claim 3, wherein, the controlling the operation of the camera underwater comprises performing a view mode for displaying a photographed picture or video by touching a view mark positioned on the touch screen.

7. The method of claim 3, wherein, the controlling the operation of the camera underwater comprises selecting a picture mode or a video mode by touching a camera mode mark positioned on the touch screen.

8. The method of claim 1, further comprising:

determining whether or not a termination condition of the camera is satisfied; and

terminating the camera.

9. The method of claim 8, wherein, the determining whether or not a termination condition of the camera is satisfied comprises determining whether a termination mark positioned on the touch screen is touched or not.

10. The method of claim 1, wherein a mark positioned on the touch screen is translucent.

11. The method of claim 1, wherein marks positioned on the touch screen are spaced apart from each other by an interval greater than a first predetermined interval.

12. The method of claim 1, wherein marks positioned on the touch screen are spaced apart from the edge of the touch screen by an interval greater than a second predetermined interval.

13. A touch input device for operating a camera, the touch input device comprising:

a touch screen including touch position sensing electrode and touch pressure sensing electrode; and

a processor;

determining whether the camera is underwater or not;

detecting a touch position of an object on the touch screen based on a capacitance change amount using the touch position sensing electrode if the camera is not underwater;

detecting the touch position of the object on the touch screen based on a capacitance change amount due to the touch pressure using the touch pressure sensing electrode if the camera is underwater, the touch position being detected by;

determining a capacitance pattern for a varying capacitance throughout the touch screen when the touch screen is underwater and no touch input occurs;

resetting, by the processor, a varying reference capacitance for determining whether a touch input by the object occurs or not, the varying reference capacitance being reset based on the determined capacitance pattern when the touch screen is underwater and no touch input occurs; and

receiving, by the touch screen, the touch pressure by the object underwater; and

detecting, by the processor, the touch position on the touch screen based on the capacitance change amount due to the touch pressure and the reset varying reference capacitance; and

controlling operation of the camera according to the detected touch position by the object.
