Abstract

Disclosed are an electronic device and a video recording method thereof. The electronic device may select multiple first image frames acquired by an image acquisition apparatus during a first time period after a recording start command is input, may select multiple second image frames acquired during a second time period before input of a recording end command corresponding to the recording start command after the first time period, and may generate a video including the selected image frames.

Claims

image acquisition circuitry; and

a processor comprising processing circuitry,

wherein the processor is configured;

to determine information related to at least one image frame acquired by the image acquisition circuitry in response to determining a recording start command,

to select at least one image frame from the acquired at least one image frame based on the determined information, and

in response to determining a recording end command corresponding to the recording start command, to generate a video including the selected at least one image frame.

2. The electronic device as claimed in claim 1, wherein the processor is configured to determine an average importance of the generated video based on importance values of the acquired at least image frame, and to reset timestamp values of the selected at least one image frame which are acquired during each of predetermined time periods when the average importance is determined as being a value in a predetermined range and

wherein the determined information includes the importance values of the acquired at least image frame.

3. The electronic device as claimed in claim 2, wherein the processor is configured to set a reproduction time interval between the selected at least one image frame having the reset timestamps based on the importance values of the respective image frames.

4. The electronic device as claimed in claim 3, wherein the processor is configured:

to determine the selected at least one image frame based on the set timestamp values in response to determining a reproduction start command, and

to reproduce the selected at least one image frame at the set reproduction time interval.

5. The electronic device as claimed in claim 1, further comprising input/output circuitry,

wherein the processor is configured:

to determine an audio data corresponding to a timestamp value of a particular image frame among audio data which are input through the input/output circuitry, and

to generate the video by combining each of the selected at least one image frame with the determined audio data.

6. The electronic device as claimed in claim 5, wherein the processor is configured to determine importance values of the acquired at least one image frame based on at least part of information of the audio data and the determined information,

wherein the information of the audio data comprises at least one information from among volume information and an audio type information and

wherein the determined information comprises at least one information from among object information on an object image-captured in the relevant image frame and image-capturing quality information.

7. The electronic device as claimed in claim 6, further comprising a sensor module comprising at least one sensor,

wherein the processor is configured:

to determine sensor data corresponding to a timestamp value of particular visual data from among sensor data which are received from the sensor module, and

to determine the importance values of each of the acquired at least one image frame based on the determined sensor data and

wherein the determined information includes the sensor data received from the sensor module.

8. The electronic device as claimed in claim 6, wherein the processor is configured:

to determine an importance value of the image data to be greater than or equal to a predetermined value, when the volume of the information of the audio data is determined as a value in a predetermined range and

determine an importance value of the image data to be greater than or equal to a predetermined value, when the audio type of the information of the audio data corresponds to a predetermined type.

9. The electronic device as claimed in claim 6, wherein the processor is configured:

to determine a size or resolution of the object image-captured in the acquired at least one image frame based on the image-captured object information, and

to determine an importance value of the image data to be greater than or equal to a predetermined value, when the object image-captured in the image frame is image-captured to be greater than or equal to a predetermined size or a predetermined resolution.

10. The electronic device as claimed in claim 6, wherein the processor is configured:

to determine identification information of the object image-captured in the image frame, and

to determine an importance value of the image data to be greater than or equal to a predetermined value, when the image-captured object represents a predetermined user or a predetermined target corresponding to the identification information.

11. A video recording method of an electronic device, the video recording method comprising:

determining information related to at least one image frame acquired by image acquisition circuitry in response to determining a recording start command;

selecting at least one image frame from the acquired at least one image frame based on the determined information; and

in response to determining a recording end command corresponding to the recording start command, generating a video including the selected at least one image frame.

12. The video recording method as claimed in claim 11, further comprising:

determining an average importance value of the generated video based on importance values of the acquired at least image frame; and

resetting timestamp values of the selected at least one image frame which are acquired during each of predetermined time periods when the average importance value is determined to be a value in a predetermined range and wherein the determined information includes the importance values of the acquired at least image frame.

13. The video recording method as claimed in claim 12, further comprising setting a reproduction time interval between the selected at least one image frame having the reset timestamps based on the importance values of the respective image frames.
