Motion of an image of a scene being captured by a digital image
acquisition device is detected and used to control parameters of
illumination of the scene by a flash lamp that is typically built into
the device. Parameters that may be controlled include the intensity,
duration and timing of light emitted by the flash lamp. Such control of
the flash illumination is preferably performed in conjunction with
adjusting one or more exposure parameters used to capture an image. Such
exposure parameters include duration, aperture and sensor gain. Motion
blur caused by movement of the camera or by movement of an object within
the scene being photographed is reduced by selecting appropriate exposure
parameters and flash light characteristics.
