Abstract
An electronic device includes an image sensor; a dynamic vision sensor (DVS); and at least one processor electrically connected to the image sensor and the DVS. The at least one processor shoots video by using the image sensor, determines the moving speed of a subject by using the DVS during the video shooting, determines the frame rate of the image sensor on the basis of the moving speed, controls that the image sensor outputs, on the basis of the frame rate, a plurality of image frames including the subject, and acquires a hyperlapse video on the basis of the plurality of image frames.
Claims20
An electronic device comprising:
- an image sensor;
- a dynamic vision sensor (DVS);
- and
- at least one processor electrically connected with the image sensor and the DVS,
- wherein memory stores instructions that, when executed by the at least one processor, cause the electronic device to:
- shoot a video by using the image sensor,
- determine a moving speed of a subject by using the DVS while shooting the video,
- determine a frame rate of the image sensor from a first frame rate to a second frame rate which is higher than the first frame rate, based on the moving speed being a second moving speed of the subject which is faster than a first moving speed of the subject,
- control the image sensor to output a plurality of image frames including the subject, based on the frame rate of the image sensor, and
- acquire a hyperlapse video based on the plurality of image frames.
An operating method of an electronic device, the method comprising:
- shooting a video by using an image sensor included in the electronic device;
- determining a moving speed of a subject by using a dynamic vision sensor (DVS) included in the electronic device while shooting the video;
- determining a frame rate of the image sensor from a first frame rate to a second frame rate which is higher than the first frame rate, based on the moving speed being a second moving speed of the subject which is faster than a first moving speed of the subject;
- controlling the image sensor to output a plurality of image frames including the subject, based on the frame rate of the image sensor;
- and
- acquiring a hyperlapse video based on the plurality of image frames.
