A method and system are provided for reducing flicker of an image defined in HTML format for display on a television monitor. When an image is retrieved from a server by a user browser system that uses a television monitor and a dedicated computer system to display HTML documents, analysis is performed on the image to determine whether the image exhibits a tendency to interlace flicker if such an image were to be displayed unmodified on the television monitor. If the analysis indicates that the image would exhibit a tendency to interlace flicker, the dedicated computer system identifies a flicker reduction filter that reduces the interlace flicker. The dedicated computer system applies the filter to the images before it is displayed on the television monitor. Otherwise, the dedicated computer system displays the image as retrieved from the server without flicker reduction filtering.
