4 results about "Lens Controller" patented technology

A camera device includes: a lens configured to receive light incident from a subject; an image sensor configured to capture an image of the subject using the received light; a distance measurer configured to identify a plurality of positions having same distance information in the image; a window setter configured to set one or more focus windows in the image based on the plurality of positions; a focus position estimator configured to determine a focus position for capturing the image using pixels within the one or more focus windows; and a lens controller configured to control a position of the lens according to the determined focus position.

Eyeglasses are provided with a variable focus lens, which is a liquid crystal lens divided into a plurality of driving regions, and a lens controller that controls a refractive index distribution generated in the variable focus lens. The eyeglasses further include a guidance data acquisition unit that acquires guidance data relating to a gaze direction to which the wearer is to be guided. Based on the guidance data, the lens controller determines at least one driving region corresponding to the gaze direction to be guided as a gaze guidance region, and generates a Fresnel lens-like refractive index distribution in the gaze guidance region.

The present invention aims to improve convenience and comfort when installing and using an optical transmission device for transmitting video signals. The present invention provides an adapter and a base station for an optical transmission system that optically transmits analog video signals or digital video signals between the adapter-base station pair, the adapter and the base station comprising a lens controller and an intercom function, the optical transmission system operating connected devices.

A system may include a camera assembly, a fluid dispensing assembly, a wiper assembly, and a controller. The camera assembly can include a lens. The controller can be in communication with the camera assembly, the fluid dispensing assembly, and / or the wiper assembly. In some examples, the controller can be configured to determine, based on image quality data generated by the camera assembly, that a debris is attached to the lens. In response to determining that the debris is attached to the lens, the controller can trigger the fluid dispensing assembly to dispense liquid onto the lens, and activate the wiper assembly to remove the debris from the lens.
