摘要：
An encoding device includes a binary image generation unit that generates at least two binary images from a multivalued image by applying different methods, a check image generation unit that generates a check image based on the plural binary images generated by the binary image generation unit, and a code generation unit that generates coded data by encoding at least one of the binary images generated by the binary image generation unit and the check image generated by the check image generation unit by using different methods.
摘要（中）：

编码装置包括二进制图像生成单元，其通过应用不同的方法从多值图像生成至少两个二值图像;基于由二值图像生成单元生成的多个二进制图像生成检查图像的检查图像生成单元，以及 代码生成单元，其通过使用不同的方法对由二值图像生成单元生成的二进制图像和由检查图像生成单元生成的检查图像进行编码来生成编码数据。
