US Patent 7528863 Remote-control device for digital camera

A remote-control device controls a digital camera, in which a first range of an exposure compensation value, which can be set when independently using the digital camera, is narrower than a potential range of the exposure compensation value, which is possible to set in the digital camera. The remote-control device sets the exposure compensation values within a range which is broader than the first range. The remote-control device makes the digital camera perform a shutter release operation, in accordance with the exposure compensation values.
