SYSTEMS AND METHODS FOR IMPROVING VIDEO STUTTER IN HIGH RESOLUTION PROGRESSIVE VIDEO
First Claim
1. A method, comprising:
- detecting that frames of a digital video sequence are associated with a shutter speed that is substantially greater than a frame rate of the digital video sequence;
determining motion information associated with a plurality of pixels in a first frame of the digital video sequence; and
in response to detecting that the frames of a digital video sequence are associated with a shutter speed that is substantially greater than a frame rate of the digital video sequence, adding a motion blur effect to at least a portion of the first frame based on the motion information.

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 objects moving within the frame to appear motionless. 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. The motion blur creates the appearance that an object is moving in the frame. In a second approach, the lens assembly of the digital camera includes an electronically controlled 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 controlled filter may be a liquid crystal display (LCD) device that is set to a plurality of different transparency levels based on a target exposure value.
