  • Method for reducing intensity variations in a video image stream depicting a scene
    Patent number: 10963997
    Abstract: A method and a digital video camera for reducing intensity variations in a video stream depicting a scene comprising capturing, using a first sensor setting, a first frame; detecting a change in intensity in a portion of the first frame, the portion represents a first area of the scene; determining a second sensor setting based on the first frame; capturing, using the second sensor setting, a second frame; creating a local tone mapping mask, wherein a local tone mapping in the first area of the scene is different from a local tone mapping in an area outside the first area, and wherein the local tone mapping in the area outside the first area is based on a relation between the first sensor setting and the second sensor setting; and applying the local tone mapping mask to the second frame.

  • Method and device for setting a focus of a camera
    Patent number: 9906724
    Abstract: The present invention relates generally to auto focus algorithms for setting a focus of a camera. More specifically, the present invention relates to a method (600) and device for setting a focus of a camera wherein a camera motion level of the camera is continuously measured (S604) during the read-out of pixel data by a rolling shutter image sensor and wherein the auto focus algorithm uses weighted focus measures which are calculated (S612) using the continuously measured camera motion levels.
