Abstract:
An electrically activated lens filter (204) with an electro-optic portion (418) having a radially and circumferentially symmetric electric field gradient is disclosed. More particularly, embodiments of the lens filter (204) include an electro-optic portion (418) having one or more conductive plugs (512) arranged around a center region (514) such that an electric field within the electro-optic portion (418) varies from a maximum at an outer rim (408) to a minimum outside of the center region (514). The lens filter (204) may include a plurality of front electrodes (409) and rear electrodes (410) accessible in an axial direction for electrically activating front and rear transparent conductive layers (414, 416), respectively.
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.
