An electronic device includes a memory, at least one camera module, and a processor operatively connected to the memory and the at least one camera module. The processor is configured to, while acquiring first recording data by using the at least one camera module, detect at least one designated gesture input on the basis of at least a part of the acquired first recording data. The processor executes a function corresponding to the detected gesture input. The processor creates and stores a second recording data in the memory. The second recording data includes data remaining after excluding, from the acquired first recording data, recording data corresponding to a time interval from the detection initiation time point of the detected gesture input to detection termination time point of same.
