Abstract: A method and circuit to strip the composite sync from the composite video signal (112) is disclosed. This invention utilizes a phase locked loop (114) and a switchable input operational amplifier (110) to remove the sync portion of the video signal (112) without band limiting or introducing non-linearities to the video signal (112). The phase locked loop (114) creates a high frequency clock (106) from which a signal can be created that fully encompasses the sync portion of the composite video signal (112). This signal controls the switchable input op-amp (110) to select blank level during sync or allow the video to pass when sync is not present.

Abstract: A circuit and method for optimizing the display of a video signal on a display. Control of the display's brightness and contrast is based on aspects of a video signal, such as the average amplitude of the signal and the standard deviation. These aspects of the video signal are determined and the video signal manipulated based on the determined characteristics such that the resultant video signal is optimized to the dynamic range of the display.

Abstract: Two or more independent video sync sources are input along with a programmable priority or order for each sync source. The sync source with the highest priority that is valid is the output. This invention shall automatically switch the highest priority valid sync to the output. The priority associated with each independent sync source is programmable and can be changed or set differently with each unit.

Abstract: An apparatus and method for controlling contrast for a liquid crystal display ('LCD'), especially active-matrix LCDs, while receiving large dynamic range video data to be displayed to the user by the LCD. Contrast settings of the LCD correspond to a single look-up table from a set of different and multiple look-up tables rather than using the contrast setting of the LCD to select different voltage values from a single look-up table. The values of the reference voltages of the LCD are varied so that all shades of gray are available with each contrast selection resulting in a high image quality and a high contrast.
