High level controls are usually software algorithms (possibly running on the sensor itself) that modify low level controls behind the scene. If a sensor exposes both an exposure time control and a scene mode control that modifies exposure time handling, documentation of the scene mode control must explain how the two interacts and what applications can and can't do. > There is some different story, I just got the N900 some days ago :). > The purpose is just understanding Nokia and TI OMAP camera architecture > well.
