Abstract
A book digitization apparatus includes an emitter that applies an energy ray to a book, a detector that detects an energy ray radiated from the book in response to a material existing in the book, and a three-dimensional data generator that generates data of a plurality of space points in accordance with the detected ray. The data of the space points associates position information of a position in a three-dimensional space within the book with a physical property value used to identify a layout pattern of the material at the position in a direction of thickness of the book.

A book digitization apparatus comprising:
- an emitter that applies an energy ray to a book;
- a detector that detects an energy ray radiated from the book in response to a material existing in the book;
- a three-dimensional data generator that generates data of a plurality of space points in accordance with the detected energy ray, wherein the data of the space points associates position information of a position in a three-dimensional space within the book with a physical property value used to identify a layout pattern of the material at the position in a direction of thickness of the book;
- and
- a two-dimensional data generator that generates two-dimensional page data of the book by using the data of the space points, wherein
- the physical property value comprises a value of reflectivity of the material in response to an application of the energy ray, and
- the two-dimensional data generator includes:
- a layout pattern identifying unit that identifies the layout pattern of the material in the direction of thickness of the book by using the physical property value;
- a surface identifying unit that identifies a page region by searching for an equal-value plane by using the data of the space points;
- and
- a data generating unit that generates the two-dimensional page data by using the data of the space points, information on the page region, and information on the layout pattern.
A book digitization method comprising:
- i) applying an energy ray to a book;
- ii) detecting an energy ray radiated from the book in response to a material existing in the book;
- iii) generating three-dimensionally data of a plurality of space points in accordance with the detected energy ray, wherein the data of the space points associates position information of a position in a three-dimensional space within the book with a physical property value used to identify a layout pattern of the material at the position in a direction of thickness of the book;
- and
- iv) generating two-dimensional page data of the book by using the data of the space points, wherein
- the physical property value comprises a value of reflectivity of the material in response to an application of the energy ray, and
- step iv) includes:
- identifying the layout pattern of the material in the direction of thickness of the book by using the physical property value;
- identifying a page region by searching for an equal-value plane by using the data of the space points;
- and
- generating the two-dimensional page data by using the data of the space points, information on the page region, and information on the layout pattern.
