Abstract

An image data generating device for generating image data pertaining to a target includes a transparent plate, a light radiation unit, a plurality of digital camera units, which are provided on a side close to a second surface of the transparent plate, and which are offset from each other and overlap the transparent plate as viewed from a direction perpendicular to a plane in which the transparent plate extends, and a photography data composition unit. The light radiated by the light radiation unit and reflected from the target directly enters the plurality of digital camera units, each of the digital camera units generating photography data pertaining to the target. The photography data composition unit combines a plural sets of photography data generated by the plurality of digital camera units and generates image data pertaining to the target. Two adjacent digital camera units generate partially-overlapping photography data.

Claims

1. An image data generating device for generating image data pertaining to a target, comprising:

a transparent plate having a first surface on which the target is to be set and a second surface that is an opposite side of the first surface;

a light radiation unit that radiates light to the target;

a plurality of digital camera units, which are provided on a side close to the second surface of the transparent plate, and which are offset from each other and overlap the transparent plate as viewed from a direction perpendicular to a plane in which the transparent plate extends; and

a photography data composition unit,

wherein the light radiated by the light radiation unit and reflected from the target directly enters the plurality of digital camera units, each of the digital camera units generating photography data pertaining to the target,

wherein the photography data composition unit combines a plural sets of photography data generated by the plurality of digital camera units and generates image data pertaining to the target, and

wherein two adjacent digital camera units generate partially-overlapping photography data.

2. The image data generating device according to claim 1,

wherein the plurality of digital camera units comprises:

a first digital camera unit that generates a first photography data of the target, the first photography data including an entire area of a first side of the target with respect to an intermediate position in a long side of the target when the rectangular target having a predetermined size is set at a predetermined position on the transparent plate; and

a second digital camera unit that generates a second photography data of the target, the second photography data including an entire area of a second side of the target with respect to the intermediate position in the long side of the target and being different from the first photography data if the rectangular target having the predetermined size is set at the predetermined position on the transparent plate, and

wherein the image data generating device further comprises;

a first image data generation unit that generates a first image data pertaining to the first side of the rectangular target using the first photography data; and

a second image data generation unit that generates a second image data pertaining to the second side of the rectangular target using the second photography data.

3. The image data generating device according to claim 2,

wherein the first image data generation unit generates, if a first short side of the rectangular target included in the first photography data is taken as a first reference position, the first image data including only a first area between the first reference position and a position spaced a predetermined distance apart from the first reference position toward a second short side,

wherein the second image data generation unit generates, if the second short side of the rectangular target included in the second photography data is taken as a second reference position, the second image data including only a second area between the second reference position and a position spaced the predetermined distance apart from the second reference position toward the first short side, and

wherein the predetermined distance is set to one-half a length of the long side of the rectangular target of the predetermined size.

4. The image data generating device according to claim 2, further comprising:

a size enlargement unit that enlarges the first image data generated by the first image data generation unit and the second image data generated by the second image data generation unit to the predetermined size, respectively.

5. The image data generating device according to claim 2, further comprising:

a mode selection unit that allows selection of a mode,

wherein, if a first mode is selected, the photography data composition unit combines the first photography data with the second photography data and generates image data pertaining to the rectangular target having the predetermined size, and

wherein, if a second mode is selected, the first image data generation unit generates the first image data pertaining to the first side of the rectangular target having the predetermined size, and the second image data generation unit generates the second image data pertaining to the second side of the rectangular target having the predetermined size.
