Abstract

A sender device of sharing screenshots comprises a detection module, a control module and a wireless network interface. The detection module detects in the background whether a user is executing a screenshot activity and outputs a corresponding trigger signal. The control module electrically connects with the detection module and retrieves a latest-taken screenshot according to the trigger signal output by the detection module. The wireless network interface electrically connects the control module for establishing a wireless network link with a receiver device and transmitting the screenshot to the receiver device. The abovementioned sender device is able to simplify the operation to share screenshots.

Claims

1. A sender device of sharing screenshots, which cooperates with a receiver device to form a screenshot sharing system, and which comprises

a detection module configured for detecting in a background whether a user is executing a screenshot activity and outputting a corresponding trigger signal;

a control module electrically connecting with said detection module and configured for retrieving a screenshot taken latest according to said trigger signal; and

a wireless network interface electrically connecting with said control module for establishing a wireless network link with said receiver device and transmitting said screenshot to said receiver device.

2. The sender device of sharing screenshots according to claim 1 further comprising an encoding module electrically connecting with said control module and configured for encoding said screenshot.

3. The sender device of sharing screenshots according to claim 1, wherein said receiver device includes an external display module or a built-in display module for presenting said screenshot.

4. The sender device of sharing screenshots according to claim 1, wherein said wireless network link works according to an IEEE 802.11-based communication standard.

5. A method of sharing screenshots, comprising steps:

establishing a wireless network link between a sender device and a receiver device;

said sender device detecting in a background whether a user is executing a screenshot activity;

if yes, said sender device retrieving a screenshot taken latest;

if no, said sender device continuing detection;

said sender device transmitting said screenshot to said receiver device; and

said receiver device using an external display module or a built-in display module to present said screenshot.

6. The method of sharing screenshots according to claim 5 further comprising a step:

said sender device encoding said screenshot.

7. The method of sharing screenshots according to claim 5, wherein said wireless network link works according to an IEEE 802.11-based communication standard.

8. A method of transmitting screenshots, which is applied to a sender device, and which comprises steps:

establishing a wireless network link with a receiver device;

detecting in a background whether a user is executing a screenshot activity;

if yes, retrieving a screenshot taken latest;

if no, continuing detection; and

transmitting said screenshot to said receiver device.

9. The method of transmitting screenshots according to claim 8 further comprising a step:

encoding said screenshot.

10. The method of transmitting screenshots according to claim 8, wherein said wireless network link works according to an IEEE 802.11-based communication standard.

11. A computer-readable medium, which stores a computer program that is loaded into a sender device to execute a method of transmitting screenshots comprising steps:

establishing a wireless network link with a receiver device;

detecting in a background whether a user is executing a screenshot activity;

if yes, retrieving a screenshot taken latest;

if no, continuing detection; and

transmitting said screenshot to said receiver device.

12. The computer-readable medium according to claim 11, wherein said method further comprises a step:

encoding said screenshot.

13. The computer-readable medium according to claim 11, wherein said wireless network link works according to an IEEE 802.11-based communication standard.
