Electronic device and method for controlling auto focusing thereof

An electronic device comprising:

• a first camera;
• a second camera;
• a memory for storing lens location conversion data mapping first lens location data for the first camera with second lens location data for the second camera;
• and
• a processor operatively connected with the first camera, the second camera, and the memory,
• wherein the memory stores instructions that, when executed, cause the processor to:
• obtain the first lens location data for the first camera based on the first camera being operated;
• obtain the second lens location data for the second camera in response to a first camera switching command for switching a selected camera from the first camera to the second camera;
• update the lens location conversion data based on the first lens location data and the second lens location data;
• and
• determine a lens location of the second camera based on the updated lens location conversion data in response to a second camera switching command for switching the selected camera from the first camera to the second camera.

A method for determining a lens location by an electronic device having a camera, the method comprising:

• obtaining a distance value using a sensor;
• determining a lens location based on the distance value while the camera is operated;
• updating calibration data based on lens location data, the lens location data including information about the distance value and the determined lens location;
• and
• determining the lens location of the camera based on the updated calibration data.

A method for determining a lens location by an electronic device having a first camera and a second camera, the method comprising:

• obtaining first lens location data for the first camera based on the first camera being operated;
• obtaining second lens location data for the second camera in response to a first camera switching command for switching a selected camera from the first camera to the second camera;
• updating lens location conversion data mapping a first lens location for the first camera and a second lens location for the second camera with each other based on the first lens location data and the second lens location data;
• and
• determining a lens location of the second camera based on the updated lens location conversion data in response to a second camera switching command for switching the selected camera from the first camera to the second camera.
