Abstract

This paper focuses on the rolling shutter distortion of CMOS image sensor coming from its unique readout mechanism as the main cause for image degradation when there are fast-moving objects. This paper proposes a post image processing scheme based on motion vector detection to suppress the rolling shutter distortion. Motion vector detection is performed based on an optical flow method at a reasonable computational complexity. A practical implementation scheme is also described.
