Solid-state image-pickup devices and associated drive methods are disclosed that simultaneously provide an image signal and a motion-detection signal. After a communication is received, it is analyzed to determine if there is a protocol identifier. Also described are various different types of expansion modules that may be coupled to the modular controller, having as variety of functions and features, as well as related methods of use and configuration of these modules in the controller. The second light-directing body is disposed between the first light-directing body and the object to be illuminated and is configured and arranged so a distance from each of the slanting portions to the surface of the second light-directing body second surface is essentially uniform. Alternatively, the integrity message can contain information to correct errors in the GPS signals.
