摘要： This invention provides an imaging lens system comprising two non-cemented lens elements with refractive power: a positive first lens element having a convex object-side surface at a paraxial region and a convex or flat image-side surface at the paraxial region; and a negative second lens element having a concave object-side surface at a paraxial region and a concave image-side surface at a paraxial region, and both the object-side and image-side surfaces being aspheric; wherein, the shape of the image-side surface of the second lens element changes from concave when near an optical axis to convex when away from the optical axis. By such arrangement, the imaging lens system has not only a shorter total track length for compact electronic products, but also the advantage of a more comparable focusing performance between the short wavelength and long wavelength applications with improved image quality.

摘要： A video stabilization method includes detecting a plurality of feature points of an inputted image frame. Next, a block motion estimation is performed onto the inputted image frame according to the feature points, thereby generating a plurality of block motion vectors corresponding to the feature points. Then, the block motion vectors are converted to a histogram to perform a statistical process. Thereafter, an initial static background motion vector is determined according to a statistic value of the histogram. Thereafter, a Gaussian distribution model and a Maximum a Posteriori (MAP) estimation are adopted to correct the initial static background motion vector to generate a global motion vector. Then, a smoothing process is performed onto the global motion vector to generate a smoothed global motion vector. A video stabilization system is also provided here.

摘要： An image processing method comprises obtaining a current frame and a previous frame, performing a bilateral motion estimation to the current frame and the previous frame for acquiring a motion vector, and performing a motion compensated interpolation to the current frame, the previous frame and the motion vector for acquiring an interpolated frame. The bilateral motion estimation uses sum of bilateral absolute difference algorithm to generate at least one sum of bilateral absolute difference, and then an adaptive parameter is added to each of the sum of bilateral absolute difference to generate at least one adaptive sum of bilateral absolute difference. A group of matching blocks having a minimum adaptive sum of bilateral absolute difference is then determined to be the group of best matching blocks. The motion vector is obtained according to the relative locations of the best matching blocks.
