Abstract

An image processing device, a camera and a method of encoding a sequence of video images into a single video stream with dynamic bitrate are provided. The sequence of video images is encoded into frames of a base layer of the single video stream using a base layer resolution and a base layer compression level. Video images of the sequence of video images corresponding to respective times before detecting an event trigger are encoded into a first set of frames of an extended layer of the single video stream. The event trigger is detected and upon detecting the event trigger, video images of the sequence of video images corresponding to respective times after detecting the event trigger are encoded into a second set of frames of the extended layer using a higher resolution than the base layer resolution or a lower compression level than the base layer compression level.
