It seems this behaviour is generic across several sensors. As far as I know, the mt9m111 has 2 modes : low power low resolution, and high power high resolution, and both are programmable apart (in terms of resolution, zoom, etc ...) What this makes me think is that a sensor could provide several "contexts" of use, as : - full resolution still image context - low resolution still image context - full resolution video context - low resolution video context Then, a new/existing v4l2 call would switch the context (perhaps based on buffer type ?) of the sensor. Well, that's just some junk I've been thinking over lately.
