Abstract: In an electronic device for controlling the shaking of a lens part of a camera module and an operation method for the electronic device according to various embodiments, the electronic device includes: a housing; a first camera that is accommodated in the housing and includes a first lens part capable of refracting light, reflected from an external object, through one surface of the housing, and a first optical image stabilizer (OIS) capable of compensating for the shaking of the first lens part; a second camera that is accommodated in the housing and includes a second lens part capable of refracting light, reflected from the external object, through the one surface and a second optical image stabilizer capable of compensating for the shaking of the second lens part; and a control circuit, wherein the control circuit may be configured to: acquire an image of the external object by using the first camera and the second camera; acquire a first signal, corresponding to the shaking of the first lens part, and a second signal, corresponding to the shaking of the second lens part, while acquiring the image; verify compensation information that is compensated so that the movement amount of the first lens part or the second lens part according to a signal corresponding to a predetermined movement amount of the first lens part or the second lens part is substantially the same as the predetermined movement amount; determine a control signal on the basis of the first signal, the second signal, and the compensation information; and move the first lens part by using the first optical image stabilizer or the second lens part by using the second optical image stabilizer on the basis of the control signal. Various other embodiments are also possible.
