A method of adjusting video image data to reduce PSE triggers, the method comprising a sequence of video images to determine if the number of changes in brightness exceeding a predetermined threshold between contiguous images is greater than a predetermined value over a predetermined time or predetermined number of video images; and if the determined number exceeds the predetermined value then applying a correction procedure to the sequence of images, wherein the correction procedure comprises: for each image, applying a plurality of candidate brightness changes to said image and subsequently determining which of the applied changes result in the number of changes in brightness between contiguous images exceeding the predetermined threshold being reduced to below the predetermined value; and selecting the determined applied change having the smallest brightness change. |
