1. A document imager comprising:
- a document bed plate on which an original document is mounted and which has a specific pattern formed on a surface thereof;
an imaging section that images the original document mounted on the document bed plate;
a first stillness judging section which judges stillness of the original document mounted on the document bed plate from at least one of (i) a discontinuity of the pattern of an outer peripheral portion in an image of the document bed plate obtained by the imaging section and (ii) a change in the outer peripheral portion in the image of the document bed plate;
a second stillness judging section which judges the stillness of the original document mounted on the document bed plate by regarding movement of apex coordinates of the original document as a change in the image of the document bed plate; and
an output section which outputs the image of the original document when both the first and second stillness judging sections judge that the original document is still.

Abstract
A computer program product executed by a computer connected with a document imager that uses an imaging section to image an original document mounted on a document bed plate on which the original document is mounted and which has a specific pattern formed on a surface thereof and outputs an image of the original document allows a CPU to execute a judging step of judging stillness of the original document mounted on the document bed plate from at least one of a discontinuity of the pattern at an outer peripheral portion in a document bed plate image obtained by the imaging section and a change in the document bed plate image.

10. A document stillness detection method for a document imager that images an original document mounted on a document bed plate having a specific pattern formed on a surface thereof by an imaging section and outputs an image of the original document, the method comprising:
-
a first judging comprising judging stillness of the original document mounted on the document bed plate from at least one of (i) a discontinuity of the pattern of an outer peripheral portion in an image of the document bed plate obtained by the imaging section, and (ii) a change in the outer peripheral portion in the image of the document bed plate; a second judging comprising judging the stillness of the original document mounted on the document bed plate by regarding movement of apex coordinates of the original document as a change in the image of the document bed plate; and outputting the image of the original document the original document is judged to be still by both the first judging and the second judging.

11. A non-transitory computer readable medium having a program stored thereon that is executable by a computer included in or connected with a document imager which uses an imaging section to image an original document mounted on a document bed plate having the original document mounted thereon and a specific pattern formed on a surface thereof and outputs an image of the original document, wherein the program is executable by the computer to perform functions comprising:
-
a first judging comprising judging stillness of the original document mounted on the document bed plate from at least one of (i) a discontinuity of the pattern of an outer peripheral portion in an image of the document bed plate obtained by the imaging section, and (ii) a change in the other peripheral portion in the image of the document bed plate; a second judging comprising judging the stillness of the original document mounted on the document bed plate by regarding movement of apex coordinates of the original document as a change in the image of the document bed plate; and outputting the image of the original document the original document is judged to be still by both the first judging and the second judging.
