A method for controlling video processing. A stream of images emanating from an image sensor is received. The contents of an image in the stream is evaluated. A part of the image stream, which part is antecedent the image being evaluated, is forwarded to a video encoder. Until the evaluation is complete, one or more empty frames are added at the end of an encoded image stream corresponding to the forwarded image stream.

Method and image-processing device for video processing

Methods and apparatus, including computer program products, for processing a stream of image frames captured by a camera system. When an image frame from the stream of image frames is dropped, a current camera movement is determined. A substitute image frame for the dropped image frame is generated. The substitute image frame comprises a reference to a previous image frame and includes one or more motion vectors estimated solely based on the determined current camera movement. Remaining image frames in the stream of image frames are encoded and the substitute image frame is inserted at the place of the dropped image frame in the stream of encoded image frames.

Generating substitute image frames based on camera motion

A method for anonymizing a digital colour image comprising obtaining the digital colour image, and applying a linear random function to a respective colour vector representing colour components of a respective pixel of the digital colour image to obtain a monochrome image. The linear random function varies over the pixels of the digital colour image, and is further dependent on at least one random parameter.
