    • An apparatus includes: a retainer moving between a shuttle and a socket; a presser holding a component; an adjuster moving the presser; a socket mark near the socket; a hand mark near the socket mark when the retainer is at a component mounting position; a first camera photographing a first image including the component and hand mark; a second camera photographing a second image including the socket mark and socket, and a third image including the socket mark and hand mark; a first calculator obtaining a first relative position between the socket mark and socket from the second image; a second calculator obtaining a second relative position between the socket mark and hand mark from the third image; and a third calculator obtaining a third relative position between the hand mark and component from the first image. The adjuster corrects the component's position based on the relative positions.

    • A periodicity determining unit determines whether an image region including a target pixel is a periodic region in which pixel values vary periodically. A first generating unit generates a pixel value using a first interpolation method. A second generating unit generates a pixel value using a second interpolation method. A control unit determines, based on the determination result of the periodicity determining unit, which one of the first and second generating units is to be used for generating a pixel value of the target pixel. A pixel value inserting unit inserts the generated pixel value to the target pixel. The periodicity determining unit includes a cycle estimating unit to estimate, using pixel values of pixels within the image region, a variation cycle of the pixel values, and/or a determining unit to determine whether each region positioned at left and right sides of the target pixel is the periodic region.
    • 周期性确定单元确定包括目标像素的图像区域是否是像素值周期性变化的周期性区域。 第一生成单元使用第一插值方法生成像素值。 第二生成单元使用第二插值方法生成像素值。 控制单元基于周期性确定单元的确定结果确定要用于生成目标像素的像素值的第一和第二生成单元中的哪一个。 像素值插入单元将生成的像素值插入到目标像素。 周期性确定单元包括:周期估计单元,用于使用图像区域内的像素的像素值估计像素值的变化周期;和/或确定单元,确定位于目标的左侧和右侧的每个区域 像素是周期性区域。
