Abstract: An information handling system camera that includes a rapid focus capability for near and far objects by selectively inserting and removing a refractive material between the camera lens and image sensor to effectively adjust the camera focusing distance. When far object focus is desired, a refractive material of predefined properties is inserted to enable an instant focus of the far object to the image sensor. When a near object focus is desired, the refractive material is removed (or replaced with a thinner material) to rapidly achieve focus. In addition, a voice coil motor or other actuator fine tunes the focus when desired. In one alternative embodiment, focus is performed only with the insertion and retraction of the refractive material so that no lens actuator is included in the camera. The refractive material extends the back focal distance between the lens and image sensor relative to the back focal distance without the refractive material. Rapid insertion of refractive material shortens the time to adjust focus relative to focus time associated with actuator-based lens movement focus.

Abstract: To improve the accuracy and the speed of an autofocus method, using which a present best focal plane (13) may be found in an automated manner, which enables a best possible image quality for an object (3), which is located at a specific working distance (11) to an optical imaging system (1), it is provided that at least one parameter used during a z-scan (17) be adapted in an automated manner as a function of a presently set optical zoom level and/or a current estimated value of the working distance (11). During the z-scan (17), a present location of a focal plane (12) of the optical imaging system (1) is displaced within a scanning range (14) along an optical z-axis (8) of the imaging system (1), wherein the individual focal planes (12) are each evaluated to identify the best focal plane (13) among them.

Abstract: A camera system includes a camera unit for capturing still or moving images of an object. The camera unit is adjustable in respect of at least one parameter relevant to the capture of the images based on a measurement signal. A measuring unit captures a distance between the object and the camera unit and includes a laser transceiver for emitting a laser signal and receiving a laser signal reflected by the object. An evaluation unit coupled to the laser transceiver provides the measurement signal. The measurement signal indicates the distance between the object and the camera unit. A lens system has at least two spaced apart lenses. The laser signal emitted by the laser transceiver passes through the lens system. At least one of the lenses is arranged in movable fashion such that the distance between the lenses is variably adjustable parallel to the laser signal transmission direction.

Abstract: The present disclosure describes imaging techniques and devices having improved autofocus capabilities. The imaging techniques can include actively illuminating a scene and determining distances over the entire scene and so that a respective distance to each object or point in the scene can be determined. Thus, distances to all objects in a scene (within a particular range) at any given instant can be stored. A preview of the image can be displayed so as to allow a user to select a region of the scene of interest. In response to the user's selection, the imager's optical assembly can be adjusted automatically, for example, to a position that corresponds to optimal image capture of objects at the particular distance of the selected region of the scene.
