An image sensor acquires a preparatory image that is lighted for a predetermined preparatory duration by a strobe. The preparatory image data corresponding to the preparatory image from the image sensor is processed and an average preparatory image luminance is determined based on the preparatory image data and weighting at least a subset of the preparatory image data. A supplemental strobe duration is generated based on the average preparatory image luminance and luminance weightings. The electronic image sensor may be activated to acquire an image with supplemental light provided by the supplemental strobe duration.

Strobe lighting system for digital images

Data is stored on a rotating memory disk by maintaining constant the relative velocity between the recording transducer and the recording media. The rotational speed of the disk is varied as the transducer is translated radially of the disk recording surface, the disk surface being divided into a number of concentric track zones each containing a predetermined number of tracks. For any given zone, an optimum rotational motor speed is established and the rotational speed of the disk is maintained at that zone speed when the transducer position signals specify a given zone. As the transducer is commanded to step to a different track in a different zone, the rotational speed of the disk is altered to match the new zone speed within a relatively short period of time. Once the transducer is located within the given zone, the rotational disk speed is maintained at that zone speed for motion within the zone.
