Abstract
A sequence of digital images are produced using an imaging sensor circuit, wherein each of the digital images was a result of light capture by the imaging sensor circuit during a respective pixel integration phase followed by analog to digital conversion during a respective readout phase. A camera actuator is driven while producing the sequence of images, wherein during a part of every respective readout phase for the sequence of digital images the actuator is driven using a linear drive circuit, and wherein during a part of every respective pixel integration phase the actuator is driven using a switch mode drive circuit. Other embodiments are also described and claimed.
