Electronic device and method for generating clock signal for image sensor in camera module

An electronic device comprising:

• a processor;
• and
• a camera module,
• wherein the camera module comprises:
• 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, and
• the processor is 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.

An electronic device comprising:

• a camera module comprising an image sensor and a circuit related to acquisition of an image;
• and
• a processor, functionally connected to the camera module,
• wherein the processor is configured to transmit a first control signal to the circuit in response to detection of an event for driving the camera module,
• the circuit is configured to generate a clock signal based at least on the first control signal received from the processor, and to provide the generated clock signal to the image sensor, and
• the image sensor is configured to acquire data for generating an image based on the clock signal and in response to reception of a second control signal from the processor, and to provide the acquired data to the processor.
