Struct libcamera::controls::ExposureTime

pub struct ExposureTime(pub i32);

Exposure time (shutter speed) for the frame applied in the sensor device. This value is specified in micro-seconds.

Setting this value means that it is now fixed and the AE algorithm may not change it. Setting it back to zero returns it to the control of the AE algorithm.

\sa AnalogueGain AeEnable

\todo Document the interactions between AeEnable and setting a fixed value for this control. Consider interactions with other AE features, such as aperture and aperture/shutter priority mode, and decide if control of which features should be automatically adjusted shouldn’t better be handled through a separate AE mode control.
