Abstract

A method and a user terminal for capturing a video frame are provided. The method includes: receiving a first user operation for capturing a video frame in a video content displayed on the user terminal; generating a first request according to the first user operation, wherein the first request comprises a time stamp and is configured to request an image or a video corresponding to the time stamp from a photographic device generating the video content; sending the first request to the photographic device; and obtaining the image or the video corresponding to the time stamp from the photographic device, wherein a resolution of the image or the video corresponding to the time stamp is higher than a resolution of the video content displayed on the user terminal.

Claims

1. A method for capturing a video frame in a user terminal, comprising:

receiving a first user operation for capturing a video frame in a video content displayed on the user terminal;

generating a first request according to the first user operation, wherein the first request comprises a time stamp and is configured to request an image or a video corresponding to the time stamp from a photographic device generating the video content;

sending the first request to the photographic device; and

obtaining the image or the video corresponding to the time stamp from the photographic device, wherein a resolution of the image or the video corresponding to the time stamp is higher than a resolution of the video content displayed on the user terminal.

2. The method according to claim 1, before receiving the first user operation, further comprising:

establishing a communication connection with the photographic device;

selecting a resolution for a video content to be displayed, wherein the selected resolution is lower than a resolution of a source video content photographed by the photographic device;

generating a second request, wherein the second request comprises the selected resolution and is configured to request the video content corresponding to the selected resolution from the photographic device;

sending the second request to the photographic device;

obtaining the video content corresponding to the selected resolution from the photographic device; and

displaying the video content.

3. The method according to claim 2, wherein the resolution for the video content to be displayed is selected based on a second user operation or a communication mode of the user terminal.

4. The method according to claim 1, wherein obtaining the image or the video corresponding to the time stamp from the photographic device comprises:

sending an address to the photographic device, such that the photographic device uploads the image or the video to the address;

receiving, from the photographic device, a message indicating that the image or the video is successfully uploaded; and

obtaining the image or the video from the address.

5. The method according to claim 1, wherein obtaining the image or the video corresponding to the time stamp from the photographic device comprises:

receiving, from the photographic device, a message indicating that the image or the video is successfully uploaded and an address indicating a position of the image or the video uploaded by the photographic device; and

obtaining the image or the video from the address.

6. A user terminal, comprising:

a processor;

a memory for storing instructions executable by the processor;

wherein the processor is configured to;

receive a first user operation for capturing a video frame in a video content displayed on the user terminal;

generate a first request according to the first user operation, wherein the first request comprises a time stamp and is configured to request an image or a video corresponding to the time stamp from a photographic device generating the video content;

send the first request to the photographic device; and

obtain the image or the video corresponding to the time stamp from the photographic device, wherein a resolution of the image or the video corresponding to the time stamp is higher than a resolution of the video content displayed on the user terminal.

7. The user terminal according to claim 6, wherein the processor is further configured to:

establish a communication connection with the photographic device;

select a resolution for a video content to be displayed, wherein the selected resolution is lower than a resolution of a source video content photographed by the photographic device;

generate a second request, wherein the second request comprises the selected resolution and is configured to request the video content corresponding to the selected resolution from the photographic device;

send the second request to the photographic device;

obtain the video content corresponding to the selected resolution from the photographic device; and

display the video content.

8. The user terminal according to claim 7, wherein the resolution for the video content to be displayed is selected based on a second user operation or a communication mode of the user terminal.

9. The user terminal according to claim 6, wherein the processor is configured to obtain the image or the video corresponding to the time stamp from the photographic device by steps of:

sending an address to the photographic device, such that the photographic device uploads the image or the video to the address;

receiving, from the photographic device, a message indicating that the image or the video content is successfully uploaded; and

obtaining the image or the video from the address.

10. The user terminal according to claim 6, wherein the processor is configured to obtain the image or the video corresponding to the time stamp from the photographic device by steps of:

receiving, from the photographic device, a message indicating that the image or the video is successfully uploaded and an address indicating a position of the image or the video uploaded by the photographic device; and

obtaining the image or the video from the address.

11. A photographic device, comprising:

a processor;

a memory for storing instructions executable by the processor;

wherein the processor is configured to;

receive a first request from a user terminal displaying a video content, wherein the first request comprises a time stamp and is configured to request an image or a video corresponding to the time stamp from the photographic device generating the video content;

extract the image or the video corresponding to the time stamp; and

provide the image or the video corresponding to the time stamp to the user terminal, wherein a resolution of the image or the video corresponding to the time stamp is higher than a resolution of the video content displayed on the user terminal.

12. The photographic device according to claim 11, wherein the processor is further configured to:

establish a communication connection with the user terminal;

receive a second request from the user terminal, wherein the second request comprises a resolution selected by the user terminal and is configured to request the video content corresponding to the selected resolution from the photographic device, and the selected resolution is lower than a resolution of a source video content photographed by the photographic device; and

provide the video content corresponding to the selected resolution to the user terminal.

13. The photographic device according to claim 12, wherein the processor is configured to provide the video content corresponding to the selected resolution to the user terminal by steps of:

converting the resolution of the source video content photographed by the photographic device so as to conform to the selected resolution; and

providing the video content corresponding to the selected resolution to the user terminal.

14. The photographic device according to claim 12, wherein the processor is configured to provide the image or the video corresponding to the time stamp to the user terminal by steps of:

receiving an address from the user terminal;

uploading the image or the video corresponding to the time stamp to the address; and

sending a message indicating that the image or the video is successfully uploaded to the user terminal.

15. The photographic device according to claim 12, wherein the processor is configured to provide the image or the video corresponding to the time stamp to the user terminal by steps of:

uploading the image or the video corresponding to the time stamp to an address indicating a position of the image or the video uploaded by the photographic device; and
