Patent number: 8150181Abstract: According to the novel method, roto-translational and zooming parameters describing spurious motion effects are determined by exploiting any of the many block matching algorithms commonly used for motion estimation for calculating a motion vector for all or for a selected number of blocks of pixels of the current frame that is processed. Some of the so calculated motion vectors are not taken into account for estimating spurious motion effects. The roto-translational and zooming parameters describing what is considered to be spurious global motion between a current frame and the precedent frame of the sequence, are calculated by processing the selected motion vectors of blocks of pixels of the frame through a recursive procedure that includes computing error values and readjusting the roto-translational and zooming parameters based on the error values.Type: GrantFiled: November 17, 2008Date of Patent: April 3, 2012Assignee: STMicroelectronics S.r.l.Inventors: Arcangelo Ranieri Bruna, Sebastiano Battiato, Giovanni Puglisi

Patent number: 7680359Abstract: A method of processing digital source images, each represented by pixel matrices, to obtain from two or more source images, representing one and the same real scene and acquired by utilizing different exposure levels, a final digital image capable of reproducing the real scene with an exposure latitude greater than that of each of the source images. The method, which can be advantageously used in digital still cameras, produces the final image by combining the source images with the help of a weighted average constructed pixel by pixel. Thanks to a special filtering to which the weighting coefficients are subjected before the weighted mean operation, the method obtains a final image in which the source images are harmoniously combined with each other.Type: GrantFiled: June 2, 2006Date of Patent: March 16, 2010Assignee: STMicroelectronics, S.r.l.Inventors: Alfio Castorina, Massimo Mancuso, Sebastiano Battiato
