Disclosed are an electronic device and a method for generating a clock signal within a camera module. The electronic device includes a processor, and a camera module, wherein the camera module may include a clock generation circuit configured to generate a second clock signal, the second clock signal being independent from a first clock signal, the first clock signal being generated by the processor, an optical correction circuit configured to be driven based on the second clock signal, and an image sensor configured to be driven while being synchronized with the optical correction circuit based on the second clock signal, wherein the processor may be configured to transfer a control command to the camera module, based on an input for driving the camera module and to acquire at least one image through the synchronized optical correction circuit and image sensor based on the second clock signal.
