    • An image recording method of recording an image onto an image recording surface by dot patterns by scanning a recording head having recording element units arranged in a direction intersecting a scanning direction, the recording element units having a light source and an optical system which receives light from the light source, forms light beams which are arranged two-dimensionally, and focuses the light beams on the image recording surface. The method includes: measuring displacement amounts of positions of light beam spots on the image recording surface generated due to a change in optical magnification of the optical system; changing a light-emitting timing at a time of start of scanning in the scanning direction, on the basis of a displacement amount in the scanning direction; and changing a resolution in the direction intersecting the scanning direction, on the basis of a displacement amount in the direction intersecting the scanning direction.
    • 一种图像记录方法,通过扫描具有沿与扫描方向相交的方向布置的记录元件单元的记录头,通过点图案将图像记录到图像记录表面上,记录元件单元具有光源和光学系统,该光学系统从 光源形成二维布置的光束,并将光束聚焦在图像记录表面上。 该方法包括:测量由于光学系统的光学倍率的变化而产生的图像记录表面上的光束点的位移量; 基于扫描方向上的位移量来改变扫描开始时的发光定时; 并且根据与扫描方向相交的方向上的位移量来改变与扫描方向相交的方向上的分辨率。

    • An imaging head faces an imaging surface and is relatively moved along the scanning surface in a predetermined scanning direction. The imaging head includes an imaging element group and an alteration section. The imaging element group is structured by a plurality of imaging elements, which are arranged two-dimensionally in a plane substantially parallel to the imaging surface. The imaging element group generates a group of image pixels at the imaging surface in a two-dimensional arrangement which is inclined, as a whole, at a predetermined inclination angle with respect to the scanning direction. The alteration section alters a number of image pixels in a direction which is inclined from the scanning direction by the inclination angle, on the basis of a difference between the predetermined inclination angle of the imaging element group and an actual inclination angle of the image pixel group.
    • 成像头朝向成像表面并且沿预定扫描方向沿着扫描表面相对移动。 成像头包括成像元件组和变更部。 成像元件组由多个成像元件构成,该成像元件在基本上平行于成像表面的平面中二维排列。 成像元件组以二维排列在成像面上产生一组图像像素,该二维排列整体上相对于扫描方向以预定的倾斜角倾斜。 改变部分基于成像元件组的预定倾斜角度和图像像素组的实际倾斜角度之间的差异来改变从扫描方向倾斜倾斜角度的方向上的多个图像像素 。
