A multi-camera control apparatus and method to maintain a location and a size of an object in a continuous viewpoint switching service are provided. The multi-camera control method of controlling a main camera configured to capture a moving object of interest and controlling at least one sub-camera configured to capture the object of interest at a different viewpoint from that of the main camera, may include extracting the object of interest from a first image generated by the main camera, controlling a capturing scheme of the main camera based on a change in a location and a size of the extracted object of interest, projecting the object of interest onto a second image generated by the sub-camera, and controlling a capturing scheme of the sub-camera based on a change in a location and a size of the projected object of interest.
