A video camera comprises an image sensor for capturing image data of image frames of a video stream; an image buffer for buffering image; and circuitry. The circuitry executes: a first evaluation function to evaluate a subset of image frames in the video stream by evaluating data pertaining to the subset of image frames and to output a corresponding first evaluation result, wherein the evaluation of an image frame has an evaluation time larger than 1/fps for the video stream; a buffer function to, for each image frame being, mark the image frame as being under evaluation and indicate to the image buffer to buffer image data of the marked image frame; and a second evaluation function to access the image buffer to evaluate image data of each of the subset of image frames based on the corresponding first evaluation result and output a corresponding second evaluation result.
