    Abstract: Abstract Some embodiments provide an apparatus for controlling the motion of a camera component. In some embodiments, the apparatus includes an actuator module. The actuator module includes a plurality of magnets. Each magnet of the plurality of magnets is poled with magnetic domains 5 substantially aligned in the same direction throughout each magnet. The apparatus further includes a coil rigidly disposed around a lens. Each magnet of the plurality of magnets contributes to the forces to adjust focus of the lens based on Lorentz forces generated from the coil.

    Abstract: Manche Ausführungsformen stellen eine Vorrichtung bereit zum Steuern der Bewegung einer Kamerakomponente. In manchen Ausführungsformen beinhaltet die Vorrichtung ein Stellantriebsmodul. Das Stellantriebsmodul weist eine Mehrzahl von Magneten auf. Jeder Magnet von den mehreren Magneten ist mit magnetischen Domänen gepolt, die in jedem Magneten im Wesentlichen durchgängig in der gleichen Richtung ausgerichtet sind. Die Vorrichtung weist ferner eine Spule auf, die starr um eine Linse herum angeordnet ist. Jeder Magnet von den mehreren Magneten trägt zu den Kräften bei, mit denen die Linse auf Basis von Lorentz-Kräften, die von der Spule erzeugt werden, scharfgestellt werden soll.

    Abstract: Some embodiments provide a device, including: a lens; one or more springs for suspending the lens; an image sensor; and an actuator for moving the lens relative to the image sensor; a controller to: position, using the actuator, the lens at an equilibrium position at which displacement of the lens due to gravity is offset by displacement of the lens due to forces from the one or more springs; and responsive to a determination that a change in orientation of the device or a change in position of the lens relative to the image sensor has exceeded a threshold: determine a new equilibrium position for the lens relative to the image sensor; and position, using the actuator, the lens at the new equilibrium position.

    Abstract: The color response of camera devices may be calibrated, using a correction factor that can account for differences in the spectra of light emitted by different light sources used during calibration. The correction factor may be calculated based on the expected spectral sensitivities of the camera devices, the power spectrum of an actual light source, and the power spectrum of a canonical light source. The correction factor is then applied to adjust a measured color response of a given camera device, so that the adjusted color response is effectively the response of the given camera device if it had been illuminated by the canonical light source. In this manner, any measured color response differences, which may be due to differences between the actual light source used and the canonical light source, can be effectively reduced (if not essentially eliminated.) Other embodiments are also described and claimed.

    Abstract: Ein System und ein Verfahren zum Erzeugen eines Bilds mit Superauflösung mithilfe einer Bilderfassungsvorrichtung. In einer Ausführungsform erfasst ein elektronischer Bildsensor eine optische Referenzprobe durch einen Strahlengang. Danach stellt ein Prozessor für optische Bildstabilisierung (OIS) den Strahlengang zum elektronischen Bildsensor um eine bekannte Menge ein. Eine zweite optische Probe wird dann entlang des eingestellten Strahlengangs erfasst, so dass die zweite optische Probe von der ersten optischen Probe um nicht mehr als einen Subpixelversatz versetzt ist. Der OIS-Prozessor kann dieses Verfahren wiederholen, um mehrere optische Proben mit mehreren Versätzen zu erfassen. Die optischen Proben können kombiniert werden, um ein Bild mit Superauflösung zu erzeugen.
