    • An image processing apparatus, an image processing method, an image forming apparatus, an image forming method, and recorded data are provided to overlap main information with sub information by using a screening method when forming a color image, thereby accurately reproducing sub information from printing data in which the overlapped image is recorded. An image input unit(26) inputs main image information. The main image information is defined by the first, second, and third color element information corresponding to at least three colors. A modulating unit(22) modulates a color difference grid pattern by sub information. The modulated color grid pattern, and the first, second, and third color element information are rotated respectively at a preset angle. And the modulated color grid pattern is overlapped with the first, second, and third color element information respectively by an overlapping unit(24). A synthesizing unit(25) synthesizes the first, second, and third color element information overlapped with the modulated color grid pattern to generate color image information.
    • 提供图像处理装置,图像处理方法,图像形成装置,图像形成方法和记录数据,以在形成彩色图像时通过使用筛选方法将主信息与子信息重叠,从而从打印准确地再现子信息 记录重叠图像的数据。 图像输入单元(26)输入主图像信息。 主图像信息由对应于至少三种颜色的第一,第二和第三颜色单元信息定义。 调制单元(22)通过子信息调制色差格栅图案。 调制色栅格图案和第一,第二和第三色素信息分别以预设角度旋转。 并且调制色格图案分别由重叠单元(24)与第一,第二和第三颜色单元信息重叠。 合成单元(25)合成与调制色格图案重叠的第一,第二和第三颜色单元信息以产生彩色图像信息。
