Abstract
Systems and methods for improving video stutter in high resolution progressive video captured with fast exposure times. In a first approach, digital video is captured with fast shutter speeds that cause each frame of the video to be sharp. A motion blur is not captured for objects moving within the frame. The video codec generates motion information that may be utilized to add an artificial motion blur to each frame of the digital video during processing in a digital video pipeline. In a second approach, the lens assembly of the digital camera includes an electronically actuated filter that attenuates the light reaching an image sensor such that the shutter speeds may be decreased in order to capture motion blur. The electronically actuated filter may be a liquid crystal display (LCD) device that is set to a plurality of different transparency levels based on the voltage applied to the LCD device.
