A camera for detecting an object in a detection zone is provided that has an image sensor for recording image data, a reception optics having a focus adjustment unit for setting a focal position, a distance sensor for measuring a distance value from the object, and a control and evaluation unit connected to the distance sensor and the focus adjustment unit to set a focal position in dependence on the distance value, and to determine a distance value with the distance sensor via a variable measurement duration that is predefined in dependence on a provisional distance value such that a measurement error of the distance value and thus, on a recording of image data of the object, a focus deviation of the set focal position from an ideal focal position remains small enough for a required image sharpness of the image data.

A user may routinely wear or hold more than one computing devices. One of the computing devices may be a head-mounted computing-device configured for augmented reality. The head-mounted computing-device may include a camera. While imaging, the camera can consume power and processing resources that diminish a battery of the head-mounted computing device. To improve a battery life and to enhance a user's privacy, imaging of the camera can be deactivated during periods when the user is not interacting with the head-mounted computing device and activated when the user wishes to interact with the head-mounted computing device. The activation of the camera can be triggered by gestured data collected by a computing device other than the head-mounted computing-device.

For correcting aberration-induced imaging errors of an optical system which includes an objective (14) and an adaptive optic (18), light (5) and a sample (20) are selected such that the light (5), in acting upon the sample (20), reduces a measurement signal (28) from the sample (20), wherein a relative variation of the measurement signal (28) depends on the intensity of the light (5). The measurement signal (28) from a focal area of the optical system in the sample (20) is registered over a first and a later second period of time (38, 37) to determine a first measurement value and a second measurement value. Over a third period of time (39) which overlaps with the first and/or the second period of time, the light (5) is focused into the focal area by means of the optical system. A measure value for the relative variation of the measurement signal (28) is determined from the first and the second measurement values and used in controlling the adaptive optic (18) as a metric to be optimized.
