Abstract
An electronic device includes a first camera that obtains a first image, a second camera that obtains a second image having a disparity with the first image, a memory that stores a first calibration parameter, and a processor that calibrates at least one of the first image and the second image by using the first calibration parameter and composes the first image and the second image. The processor is configured to collect, if a specified event occurs, images obtained from the first camera and the second camera after the specified event occurs and store the collected images in the memory, to compute a second to calibration parameter based on the images obtained after the specified event occurs, if a specified condition is satisfied, and to update the first calibration parameter with the second calibration parameter.
