An electronic device comprising: a first camera including one or more image sensors; a second camera including one or more image sensors; a buffer; a memory; and a processor (120; 320), wherein the processor is configured to: set (403; 1003) a configuration related to operations of first and second cameras, comprising: setting first capturing attributes corresponding to the first camera, comprising a view angle of the first camera; and setting second capturing attributes corresponding to the second camera comprising setting a view angle equal to the view angle of the first camera; acquire (405; 1001) first images corresponding to an external object at a first frame rate through the first camera based on a signal for capturing the external object, transmit the first images to a codec that is configured to store, in the memory, the first images as images corresponding to the external object; and in response to identifying (407:YES; 1005:YES) a frame rate change event during the acquisition of the first images by the first camera, acquire (409; 1007) second images corresponding to the external object at a second frame rate, higher than the first frame rate, through the second camera, temporarily store the second images and first images acquired while acquiring the second images in the buffer, analyse at least one frame included in the second images and determine whether the second images are appropriate for the second frame rate; when the second images are appropriate for the second frame rate, transmit the second images, instead of the first images, to the codec, during a period in which the second images are acquired and delete the first images stored in the buffer, wherein the transmitted second images are stored in the memory as the images corresponding to the external object by the codec, and wherein setting the second capturing attributes is performed at the same point in time as setting the first capturing attributes, or before acquiring the first images. a first camera including one or more image sensors; a second camera including one or more image sensors; a buffer; a memory; and a processor (120; 320), wherein the processor is configured to: set (403; 1003) a configuration related to operations of first and second cameras, comprising: setting first capturing attributes corresponding to the first camera, comprising a view angle of the first camera; and setting second capturing attributes corresponding to the second camera comprising setting a view angle equal to the view angle of the first camera; acquire (405; 1001) first images corresponding to an external object at a first frame rate through the first camera based on a signal for capturing the external object, set (403; 1003) a configuration related to operations of first and second cameras, comprising: setting first capturing attributes corresponding to the first camera, comprising a view angle of the first camera; and setting second capturing attributes corresponding to the second camera comprising setting a view angle equal to the view angle of the first camera; setting first capturing attributes corresponding to the first camera, comprising a view angle of the first camera; and setting second capturing attributes corresponding to the second camera comprising setting a view angle equal to the view angle of the first camera; acquire (405; 1001) first images corresponding to an external object at a first frame rate through the first camera based on a signal for capturing the external object, transmit the first images to a codec that is configured to store, in the memory, the first images as images corresponding to the external object; and in response to identifying (407:YES; 1005:YES) a frame rate change event during the acquisition of the first images by the first camera, acquire (409; 1007) second images corresponding to the external object at a second frame rate, higher than the first frame rate, through the second camera, temporarily store the second images and first images acquired while acquiring the second images in the buffer, analyse at least one frame included in the second images and determine whether the second images are appropriate for the second frame rate; when the second images are appropriate for the second frame rate, transmit the second images, instead of the first images, to the codec, during a period in which the second images are acquired and delete the first images stored in the buffer, wherein the transmitted second images are stored in the memory as the images corresponding to the external object by the codec, and wherein setting the second capturing attributes is performed at the same point in time as setting the first capturing attributes, or before acquiring the first images.
