View Patent ↗An image generation apparatus includes an additional image information generation section and a superposition information generation section. The additional image information generation section 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. The superposition information generation section 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.
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.
2. The apparatus according to claim 1 , wherein the position information is generated in the image generation apparatus or is input from an external unit.
3. The apparatus according to claim 1 , wherein the control information is generated in the image generation apparatus or is input from an external unit.
4. The apparatus according to claim 1 , wherein the document information is previously stored in the image generation apparatus or is input from an external unit.
5. The apparatus according to claim 1 , further comprising:
a recording section that records the superposition information on the recording medium, wherein:
the recording section forms the second image information of the control information and the first image information of the position information with different color materials.
6. The apparatus according to claim 5 , wherein an infrared absorption amount of the color material used for the second image information of the control information is a half or less of an infrared absorption amount of the color material used for the first image information of the position information.
7. The apparatus according to claim 1 , wherein the additional image information generation section generates the additional image information in which identification information that identifies the recording medium or the document information recorded on the recording medium is placed as fourth image information in the partitions formed by two-dimensionally placing the position information as the first image information, together with the control information.
8. The apparatus according to claim 7 , wherein the identification information is generated in the image generation apparatus or is input from an external unit.
9. The apparatus according to claim 8 , wherein the additional image information generation section places the control information and the identification information alternately in the partitions formed by two-dimensionally placing the position information as the first image information.
10. A non-transitory computer readable medium storing a program causing a computer to execute a process for information generation, the process comprising:
generating 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;
converting acquired document information in third image information; and
superposing the third image information and the generated additional image information 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.
11. An image generation method comprising:
generating 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;
converting acquired document information into third image information; and
superposing the third image information and the generated additional image information 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.
12. The apparatus according to claim 1 , wherein
the control information includes copy prohibition information, scan prohibition information and FAX prohibition information.
