摘要： Methods and systems for coded rolling shutter are provided. In accordance with some embodiments, methods and system are provided that control the readout timing and exposure length for each row of a pixel array in an image sensor, thereby flexibly sampling the three-dimensional space-time value of a scene and capturing sub-images that effectively encode motion and dynamic range information within a single captured image.

摘要： An image processing method is disclosed. The image processing method uses a first still image and a second still image which are chronologically successive and outputs an image from which noise has been reduced. A motion of the second still image is compensated block by block. Reliability of addition of the first still image and the motion-compensated second still image is determined pixel by pixel and a weighting factor is set corresponding thereto. The first still image and the motion-compensated second still image are added or averaged with the weighting factor and a processed image is obtained.
