Zusammenfassung:The present invention relates to an electronic device controlling shaking of a lens unit of a camera module and an operation method for the same. The electronic device controlling shaking of the lens unit of the camera module can correct hand shaking by sensing a change of a magnetic field generated by a movement of a lens due to the hand shaking by using a hall sensor and moving a lens in a direction of offsetting the movement of the lens. According to various embodiments of the present invention, the electronic device includes: a housing; a first camera accommodated in the housing and including a first lens unit capable of refracting light reflected from an outer subject through one side of the housing, and a first optical image stabilizer (OIS) capable of correcting shaking of the first lens unit; a second camera accommodated in the housing and including a second lens unit capable of refracting the light reflected from the outer subject through the one side, and a second OIS capable of correcting shaking of the second lens unit; and a control circuit. The control circuit obtains an image on the outer subject by using the first camera and the second camera and obtains a first signal corresponding to the shaking of the first lens unit and a second signal corresponding to the shaking of the second lens unit while obtaining the image. The control circuit confirms correction information corrected in order for a predetermined moving rate of the first lens unit or the second lens unit to be actually the same as the moving rate of the first lens unit or the second lens unit in accordance with the signal corresponding to the predetermined moving rate. The control circuit can be also set to determine a control signal based on the first signal, the second signal, and the correction information and move the first lens unit using the first OIS or moving the second lens unit by using the second OIS. Besides, various embodiments are possible. 다양한 실시예에 따른 카메라 모듈의 렌즈부의 흔들림을 제어하는 전자 장치 및 전자 장치의 동작 방법에서 전자 장치는 하우징; 상기 하우징에 수용되고, 상기 하우징의 일면을 통해 외부 객체로부터 반사된 빛을 굴절 시킬 수 있는 제 1 렌즈부 및 상기 제 1 렌즈부의 흔들림을 보정할 수 있는 제 1 광학식 흔들림 보정부(OIS, optical image stabilizer)를 포함하는 제1 카메라; 상기 하우징에 수용되고, 상기 일면을 통해 상기 외부 객체로부터 반사된 빛을 굴절 시킬 수 있는 제 2 렌즈부 및 상기 제 2 렌즈부의 흔들림을 보정할 수 있는 제 2 광학식 흔들림 보정부를 포함하는 제2 카메라; 및 제어 회로를 포함하고, 상기 제어 회로는, 상기 제1 카메라 및 상기 제2 카메라를 이용하여 외부 객체에 대한 이미지를 획득하고, 상기 이미지를 획득하는 동안에, 상기 제 1 렌즈부의 흔들림에 대응하는 제 1 신호 및 상기 제 2 렌즈부의 흔들림에 대응하는 제 2 신호를 획득하고, 상기 제 1 렌즈부 또는 상기 제 2 렌즈부의 지정된 이동
