Abstract
An image sensor system and associated method supporting multiple video output standards, such as NTSC and PAL, including a pixel array corresponding in size to the frame size having a smaller line number of the video standards, is described. System and method for resolving discrepancies between standards includes multiple crystal oscillators or frequency synthesis to derive a dot clock, and a standard-specific pixel read-out scheme that provides additional lines when outputting according to the frame size having a larger line number of the video standards. In an embodiment, additional line video data is derived by duplicating a line of image data, and in an alternative embodiment additional line video data is derived by digital vertical interpolation.
