Abstract

It is expected to provide a document image generating apparatus, a document image generating method and a computer program that can keep a layout of original text present in the original text image and then can improve the readability of original text and the readability annotation corresponding to the original text (e.g., translation).

A translation 421 of original text 411 is aligned at the interline space between the original text 411 at the first line and the original text 412 at the second line. When the interline space is narrow as shown in FIG. 4B, the original text 411 overlays the translation 421. At that time, the color regarding the original text 411 is changed to be a low visibility color, and the color regarding the translation 421 is changed to be a high visibility color.

Claims

1. A document image generating apparatus, comprising:

an accepting unit that accepts an original image;

an extracting unit that extracts an original text from the original image accepted by the accepting unit;

an annotation generating unit that generates an annotation corresponding to the original text extracted by the extracting unit;

an annotation color setting unit that sets a color of the annotation generated by the annotation generating unit; and

a document image generating unit that generates a document image in which the annotation generated by the annotation generating unit is added with the color set by the annotation color setting unit to the original image accepted by the accepting unit, wherein

in the document image generated by the document image generating unit, a color of the original text is different from the color of the annotation.

2. A document image generating apparatus according to claim 1, further comprising:

a layer generating unit that generates an original layer representing the original image accepted by the accepting unit and an annotation layer representing the annotation generated by the annotation generating unit, wherein

the document image generating unit composites the original layer and the annotation layer generated by the layer generating unit, in order to generate the document image.

3. A document image generating apparatus according to claim 2, further comprising:

a determining unit that determines whether the color of original text extracted by the extracting unit satisfies a predetermined condition or not;

an original text color changing unit that changes the color of original text in the document image to be a color which satisfies the predetermined condition when the determining unit determines that the color of original text extracted by the extracting unit does not satisfy the predetermined condition, and that fails to change the color of original text in the document image to be the color which satisfies the predetermined condition when the determining unit determines that the color of original text extracted by the extracting unit satisfies the predetermined condition, wherein

the color set by the annotation color setting unit does not satisfy the predetermined condition.

4. A document image generating apparatus according to claim 1, further comprising:

a selecting unit that selects either an original text priority mode for preferring a visibility of the original text or an annotation priority mode for preferring a visibility of the annotation, wherein

when the selecting unit selects the original text priority mode, the visibility of the original text becomes higher than the visibility of the annotation in the document image, and

when the selecting unit selects the annotation priority mode, the visibility of the annotation becomes higher than the visibility of the original text in the document image.

5. A document image generating apparatus according to claim 4, wherein

when the selecting unit selects the original text priority mode in the case that a background color of the document image is white, a lightness of the original text becomes lower than a lightness of the annotation in the document image, and

when the selecting unit selects the annotation priority mode in the case that the background color of the document image is white, the lightness of the annotation becomes lower than the lightness of the original text in the document image.

6. A document image generating apparatus according to claim 4, wherein

when the selecting unit selects the original text priority mode in the case that a background color of the document image is white, a saturation of the original text becomes higher than a saturation of the annotation in the document image, and

when the selecting unit selects the annotation priority mode in the case that the background color of the document image is white, the saturation of the annotation becomes higher than the saturation of the original text in the document image.

7. A document image generating apparatus according to claim 4, wherein

when the selecting unit selects the original text priority mode in the case that a background color of the document image is white, a non-transparency of the original text becomes higher than a non-transparency of the annotation in the document image, and

when the selecting unit selects the annotation priority mode in the case that the background color of the document image is white, the non-transparency of the annotation becomes higher than the non-transparency of the original text in the document image.

8. A document image generating apparatus according to claim 1, further comprising:

a dividing unit that divides the annotation generated by the annotation generating unit into plural divisional annotations, wherein

the annotation color setting unit sets a color of each of the plural divisional annotations, in order to set the color of annotation generated the annotation generating unit.

9. A document image generating unit according to claim 3, wherein

the layer generating unit further generates a color change layer,

the original text color changing unit utilizes the color change layer generated by the layer generating unit to change the color of the original text, and

the document image generating unit composites the original layer, the annotation layer and the color change layer generated by the layer generating unit to generate the document image.

10. A document image generating apparatus according to claim 9, wherein

the color change layer generated by the layer generating unit comprises a color-filled diagram having a predetermined transparency, and

a position of the color-filled diagram in the color change layer corresponds to a position of the original text in the original layer.

11. A document image generating apparatus according to claim 10, wherein

a shape of the color-filled diagram is rectangle.

12. A document image generating apparatus according to claim 11, further comprising:

a separating unit that separates the original text extracted by the extracting unit into plural divisional original texts, wherein

in the color change layer generated by the layer generating unit, single of the color-filled diagram is arranged for each of the plural divisional original texts.

13. A document image generating apparatus according to claim 11, further comprising:

a separating unit that separates the original text extracted by the extracting unit into plural divisional original texts, wherein

in the color change layer generated by the layer generating unit, plural of the color-filled diagram are arranged for each of the plural divisional original texts.

14. A document image generating apparatus according to claim 13, further comprising:

a magnification setting unit that sets vertical and horizontal magnifications of the plural of the color-filled diagram in accordance with shapes of characters included each of the plural divisional original texts.

15. A document image generating apparatus according to claim 13, further comprising:

an arrangement position setting unit that sets positions for arranging the plural of the color-filled diagram in accordance with shapes of characters included each of the plural divisional original texts.

16. A document image generating apparatus according to claim 10, further comprising:

a color-filled diagram color setting unit that sets a color of the color-filled diagram to be a color corresponding to a background color of the original image accepted by the accepting unit
