    摘要: A set of screens is provided for use in printing respective color separations in a halftone color printing process. This set of screens comprises at least two clustered-dot screens and the frequency and angle parameter values of the screens is such that the lowest frequency moiré produced by any combination of at least two frequency components, taken from the group comprising the first and second screen harmonics, for which the sum of the harmonic orders of the frequency components in the combination is less than a predetermined value, is of a sufficiently high frequency as to be substantially unperceivable to the human visual system; other moirés are also substantially unperceivable to the human visual system. The lowest frequency moiré serves to reduce the visibility of color changes caused by color plane registration variations. A printing system and method employing the screen set are also provided.

    摘要: A method comprises receiving a focusing image and shifting the focusing image to obtain a shifted focusing image. In the method, a focus metric of the focusing image is calculated from the focusing image and the shifted focusing image, where the focus metric is configured for use as a factor in making an automatic focus adjustment determination. An automatic focusing apparatus includes a controller configured to implement the method.

    摘要: Methods, machines, and computer-readable media storing machine-readable instructions for processing video frames are described. In one aspect, a respective set of three-dimensional forward transform coefficients is computed for each of multiple positions of a three-dimensional blocking grid relative to an input video block comprising a selected set of video frames. The sets of three-dimensional forward transform coefficients are processed. A respective three-dimensional inverse transform is computed from each set of processed forward transform coefficients. An output video block is generated based on the computed three-dimensional inverse transforms.

    摘要: Two imaging equipment are provided at a pair of cutting blade units, and the two imaging equipment image patterns at first positions in proximity to the center of a wafer at the same time. A controller drives drive mechanisms to align the wafer in such a way that current image patterns at the first positions can match with a reference pattern at the first positions. Then, the two imaging equipment are moved to positions for imaging patterns at second positions at the outer circumference of the wafer to image the patterns at the second positions. The controller drives the drive mecha- nisms to align the wafer in such a way that current image patterns at the second positions can match with a reference pattern at the second positions.
