Classification: CPC H | IPC H

Claim 10:
11. A control method of an electronic device, the control method comprising:
setting a maximum exposure time based on an input of a user or a specified algorithm;
determining a number of at least one source frame per unit second based on the maximum exposure time and a resetting time taken to read out the at least one source frame;
receiving light reflected from an external object during an exposure time determined according to a specified exposure value, the determined exposure time being less than the maximum exposure time;
generating source frames at a first speed corresponding to the determined number of at least one source frame per unit second based on the received light; and
generating a time-lapse image including at least one target frame indicating motion of the external object over time based on the generated source frames,
wherein the generating of the source frames comprises:
generating the source frames at the first speed different from a second speed at which the time-lapse image including the at least one target frame is played.
