1. An electronic device, comprising:
a display;
a camera;
a memory; and
a processor operatively connected with the display, the camera, and the memory,
wherein the memory stores instructions, when executed, causing the processor to:
set a maximum exposure time based on an input of a user or a specified algorithm;
determine 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;
receive light reflected from an external object during an exposure time determined according to a specified exposure value using the camera, the determined exposure time being less than the maximum exposure time;
generate 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
generate a time-lapse image including at least one target frame indicating motion of the external object over time based on the source frames, and
wherein the first speed is different from a second speed at which the time-lapse image including the at least one target frame is played.
