Latest Patents

One of his latest patents is a system and method to enhance the optical bokeh effect of computing device cameras. This invention describes methods and systems for achieving an optical bokeh effect by a camera supporting a computing device, such as a laptop computer. A measurement is performed to determine the focus spot position of a subject. The depth of field (DOF) of the camera lens is then established. An offset regarding the focus spot position is calculated to blur the background of the subject, thereby increasing the optical bokeh effect. The offset is added to the focus spot position or adjusted to decrease optical bokeh in the background, resulting in a focus spot position that supports the desired optical bokeh effect. The camera lens is subsequently adjusted for the new focus spot position.

Another notable patent is for an information handling system camera that features a multi-filter ICR within a defined focal distance. This camera supports multiple filters that can be selectively inserted between a lens and an image sensor by several actuators positioned around the perimeter of the lens and image sensor. This design ensures that the actuators do not add to the vertical height of the camera. The plural actuators allow for the simultaneous insertion of multiple filters, which work together to provide day, night, distance detection, and camera focus distance and zoom levels through the refractive manipulation of light passing through a neutral density (transparent) piece of material of increased thickness.
