Abstract: An electronic device includes: a motion sensor for outputting motion data corresponding to motion of the electronic device; a camera module for performing an OIS function within a operation range when the motion data has a first size; and a processor electrically connected to the motion sensor and the camera module. The processor acquires motion data from the motion sensor while continuously acquiring image frames through the camera module, determines, based on the motion data, a parameter associated with the OIS function such that the camera module performs the OIS function within the operation range using the parameter based on determination that the motion data has the second size lager than the first size, and acquire image frames for which the OIS function has been performed within the operation range using the determined parameter.

Abstract: An electronic device according to an embodiment of the present disclosure may comprise: a camera module including an OIS actuator and an image sensor for performing read-out of an image frame acquired through image stabilization by the OIS actuator; at least one motion sensor; and at least one processor. The at least one processor may be configured to: acquire a first read-out image frame through the image sensor; acquire a first vertical synchronization signal (Vsync) corresponding to the first image frame from the image sensor; acquire multiple pieces of motion data of the electronic device through the at least one motion sensor during the read-out of the first image frame; determine (identify) first motion data corresponding to a first time point at which the read-out of the first image frame is completed, on the basis of the first vertical synchronization signal; and perform digital image stabilization (DIS) for the first image frame using the first motion data and at least one piece of second motion data acquired before the first motion data among the multiple pieces of motion data.
