An electronic device and a camera switching method thereon are provided. The electronic device includes a first camera module, a second camera module, a touch screen and a processor. The touch screen is configured to detect a touch event, wherein the touch event is triggered as the touch screen is touched and dragged from a first position to a second position. The processor is configured to switch between the first camera module and the second camera module in response to the touch event. The camera switching method is applied to the electronic device to implement the operations.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An electronic device, comprising: a first camera module; a second camera module; a touch screen, configured to detect a touch event; and a processor, coupled with the first camera module, the second camera module and the touch screen and configured to switch between the first camera module being running and the second camera module being idle in response to the touch event; wherein the touch event is triggered as the touch screen is touched and dragged from a first position to a second position; wherein the processor is further configured to initiate the second camera module being idle in response to the touch event before the first camera module being running is switched to the second camera module being idle; and wherein when the second camera module is fully initiated, the second camera module becomes running from being idle.
2. The electronic device as claimed in claim 1 , wherein the touch screen is further configured to: display a first image frame which is provided by the first camera module until the second camera module is initiated; and display a second image frame which is provided by the second camera module after the second camera module is fully initiated.
3. The electronic device as claimed in claim 2 , wherein the touch screen is further configured to display a third image frame during the initiation of the second camera module.
4. The electronic device as claimed in claim 1 , wherein the first position is inside a first predetermined area next to one border of the touch screen and the second position is outside a second predetermined area next to the border of the touch screen.
5. The electronic device as claimed in claim 4 , the first predetermined area is ⅙ of the surface area of the touch screen and the second predetermined area is ⅓ of the surface area of the touch screen.
6. The electronic device as claimed in claim 1 , wherein the touch screen is further configured to display an image frame which is provided by the second camera module only after the second camera module is fully initiated.
7. A camera switching method for use in an electronic device, the electronic device comprising a first camera module, a second camera module, a touch screen and a processor, the camera switching method comprising the following steps of: (a) detecting a touch event by the touch screen, wherein the touch event is triggered as the touch screen is touched and dragged from a first position to a second position; and (b) switching between the first camera module being running and the second camera module being idle by the processor in response to the touch event; wherein the step (b) further comprises the following step of: (b1) initiating the second camera being idle module by the processor in response to the touch event before the first camera module being running is switched to the second camera module being idle; and wherein when the second camera module is fully initiated, the second camera module becomes running from being idle.
8. The camera switching method as claimed in claim 7 , further comprising the following steps of: (c) displaying a first image frame which is provided by the first camera module by the touch screen until the second camera module is initiated; and (d) displaying a second image frame which is provided by the second camera module by the touch screen after the second camera module is fully initiated.
9. The camera switching method as claimed in claim 8 , further comprising the following step of: (e) displaying a third image frame by the touch screen during the initiation of the second camera module.
10. The camera switching method as claimed in claim 7 , wherein the first position is inside a first predetermined area next to one border of the touch screen and the second position is outside a second predetermined area next to the border of the touch screen.
11. The camera switching method as claimed in claim 10 , the first predetermined area is ⅙ of the surface area of the touch screen and the second predetermined area is ⅓ of the surface area of the touch screen.
12. The camera switching method as claimed in claim 7 , further comprising the following steps of: displaying an image frame which is provided by the second camera module by the touch screen only after the second camera module is fully initiated.
