Abstract:
A letterbox detector includes a detection module configured to determine aspect ratio changes in an input signal. A transition module is configured to transition between a plurality of display modes associated with the aspect ratio changes. A first display mode to a second display mode transition is performed over a first period of time, and a second display mode to a first display mode is performed gradually over a second period of time, that is different from the first period of time. The letterbox detector may be included in digital and analog displays.
