Method and electronic device for focus control

An electronic device comprising:

• a camera including a lens driving part, the lens driving part comprising a first lens driving part and a second lens driving part;
• a memory configured to store first unit information and second unit information, which are used to move the lens driving part, wherein the first unit information is configured such that the camera causes a first focus sharpness variation and the second unit information is configured such that the camera causes a second focus sharpness variation;
• and
• a processor,
• wherein the processor is configured to:
• receive a signal for adjusting a focus associated with an external object by using the camera;
• verify a state of the electronic device associated with the received signal;
• select corresponding unit information among the first unit information and the second unit information, based at least partly on the state of the electronic device;
• and
• move the lens driving part depending on the corresponding unit information to adjust the focus associated with the external object.

An electronic device comprising:

• a display;
• a first camera module including a first lens module and a first lens driving part configured to move the first lens module in a first movement unit;
• a second camera module including a second lens module and a second lens driving part configured to move the second lens module in a second movement unit;
• and
• a processor electrically connected to the first camera module and the second camera module,
• wherein the processor is configured to:
• receive a user input with respect to one or more external objects, in a state where the first camera module is activated;
• determine activation of the second camera module with respect to the one or more external objects, in response to the user input;
• and
• present a user interface controlled such that a difference between a first focus sharpness variation of the first camera module changed by a change of a focus of the first camera module and a second focus sharpness variation of the second camera module changed by a change of a focus of the second camera module belongs within a specified range, through the display based at least partly on the activation of the second camera module.
