Samsung patents camera system that adjusts stabilization to prevent blur

1. An electronic device comprising: a motion sensor configured to output motion data corresponding to motion of the electronic device; a camera module comprising an image sensor and configured to perform an optical image stabilization (OIS) function within an operation range when the motion data has a size within a first size, wherein the first size is smaller than a critical size in which a lens is controlled in order to perform an OIS function; and at least one processor electrically connected to the motion sensor and the camera module, wherein the at least one processor is configured to: determine an exposure time of the image sensor for acquiring image frames; acquire the motion data having a second size larger than the critical size from the motion sensor while continuously acquiring the image frames through the camera module, determine a parameter associated with the OIS function based on the exposure time and the motion data having the second size such that the camera module performs the OIS function within the operation range using the determined parameter based on determination that the motion data has the second size larger than the critical size, acquire the image frames for which the OIS function is performed within the operation range using the determined parameter, and perform a video digital image stabilization (VDIS) function with respect to the image frames, based on the motion data having the second size and a motion compensation value applied to acquiring the image frames by using the OIS function, wherein the parameter is a suppression ratio related to a degree of the OIS function with respect to the motion data having the second size larger than the critical size, the parameter is determined to decrease in response to an increase of the size of the motion data larger than the critical size, and the parameter is determined based on a magnitude of a value obtained by multiplying the exposure time and the motion data.
