Abstract: An apparatus and a method implemented in a computer system for obscuring a first region of an image composed by a plurality of pixels. The method comprising obtaining a mask, the mask defining an obscurity level for each pixel in the first region of the image, and obscuring pixels in the first region of the image based on the mask's obscurity level for each pixel.

Abstract: The present invention relates to a method and a camera for determining an image adjustment parameter. The method includes receiving a plurality of images representing an image view, detecting from the plurality of images events of a specific event type, identifying a location within the image view where the event of the specific type is present, determining a presence value of each of the identified locations, and determining an image adjustment parameter based on data from an adjustment location within the image view. The adjustment location is determined based on the presence value in each location of a plurality of locations within the image view.
