Abstract:
1. An image generation apparatus comprising: an additional image information generation section that generates additional image information in which control information, which controls operation of a machine for reading information recorded on a recording medium, is placed as second image information in partitions formed by two-dimensionally placing position information, which are unique to positions on the recording medium or unique to recording positions of a document image recorded on the recording medium as first image information; and a superposition information generation section that converts acquired document information into third image information and superposes the third image information and the additional image information generated by the additional image information generation section to generate superposition information, wherein a control code block to embed the information recorded on the recording medium includes a first code block and a second code block, wherein the first code block includes a synchronous code, the second code block is placed on an area of the code block other than the area where the first code block is placed, the synchronous code indicates rotation angles of code blocks, and the second code block includes the superposed information superposed by the superposition information generation section.
