摘要： A method for generating a series of images at different zoom angles is disclosed. The method comprises providing an optical device (1) having a liquid-based zoom lens (10) and image recording means (20), recording a first image of an object at a first zoom angle responsive to a user input; and automatically recording a second image of the object at a second zoom angle after recording the first image. The switching speed of a liquid-based zoom lens (10), such as a zoom lens based on electrowetting principles is utilized to automatically generate additional images at different zoom angles, which can be advantageously combined with the image taken by the user of the optical device (1).

摘要： The present invention discloses an electronic device (1) comprising an optical device (10) having a container enclosing an insulating liquid (A) and an electrically susceptible liquid (B), the insulating liquid (A) and the electrically susceptible liquid (B) being immiscible and being in contact with each other via an interface (14), at least one of the liquids (A; B) being at least partially placed in a light path through the container. The electronic device further comprises first signal generating means (34) for generating a control signal indicative of a difference between the actual position of the interface (14) and a desired position; second signal generating means (50) for generating a further control signal for adapting the position of the interface (14) in response to the control signal; and control means (40) for prohibiting the second signal generating means (50) to update the further control signal during a positional change of the interface. Consequently, it is avoided that an update of the further control signal, e.g. a driving voltage of the optical device, is based on a control signal, e.g. a focus error signal, derived from an unstable interface (14).

摘要： A controllable optical lens system, comprises a chamber housing first and second fluids, the interface between the fluids defining a lens surface. An electrode arrangement controls the shape of the lens surface and has first and second electrodes. A parameter is determined by the system dependent on the electrical resistance through at least one of the lens fluids between the first and second electrodes. Thus, the series resistance through a lens fluid is used as a measure of meniscus position.

摘要： The present invention discloses an optical device comprising a container enclosing an insulating liquid (A) and a liquid responsive to an electric field (B), the insulating liquid (A) and the liquid responsive to an electric field (B) being immiscible and being in contact with each other via an interface (14), at least one of the liquids (A; B) being at least partially placed in a light path through the container. The optical device further comprises an electrode arrangement (2; 12) for controlling the shape of the interface (14) by means of a voltage; and means (100) for preventing the interface from an exposure to an external electric field. Consequently, the build-up of electrostatic charge on a surface of the optical device is avoided, which prevents the unwanted distortion of the interface (14) caused by the interaction of the liquid responsive to an electric field (B) and the electrostatic charge.
