Abstract: A flash removal system identifies and removes flash lighting from a video. The flash removal system identifies flash-exposed frames in the video based on a time stamp of the frame, an average luminance of the frame, or a user input. The flash removal system generates a replacement frame for each identified flash-exposed frame based on at least one frame of the video. The flash removal system replaces the flash-exposed frames with the replacement frames, generating a modified video having reduced flash lighting.
