Abstract
According to the present embodiment, an image-reading apparatus determines any one or both of the type of document and the shape of a document, selects any one or both of an appropriate document tilt detection method and an appropriate document position detection method according to any one or both of the determined type of document and the determined shape of a document, and detects any one or both of the tilt of the document and the position of the document by the selected detection method.
Claims13
An image-reading apparatus that reads an image of a document comprising a Central Processing Unit (CPU) programmed to:
- determine any one or both of a type of document and a shape of a document;
- select any one or both of an appropriate document tilt detection method and an appropriate document position detection method according to any one or both of the determined type of document and the determined shape of the document;
- detect any one or both of a tilt of the document and a position of the document by using the selected detection method;
- and
- when clipping is performed by using a detected rectangle, determine whether an occurring lack of a document exceeds a predetermined acceptable level.
An image-reading method executed by a computer comprising:
- a document determining step of determining any one or both of a type of document and a shape of a document;
- a detection-method selecting step of selecting any one or both of an appropriate document tilt detection method and an appropriate document position detection method according to any one or both of the determined type of document and the determined shape of the document;
- a document detecting step of detecting any one or both of a tilt of the document and a position of the document by using the selected detection method;
- and
- a determining step of determining whether an occurring lack of a document exceeds a predetermined acceptable level, when clipping is performed by using a detected rectangle.
A non-transitory computer readable medium including programmed instructions, the instructions, when executed by a computer, causing the computer to execute:
- a document determining step of determining any one or both of a type of document and a shape of a document;
- a detection-method selecting step of selecting any one or both of an appropriate document tilt detection method and an appropriate document position detection method according to any one or both of the determined type of document and the determined shape of the document;
- a document detecting step of detecting any one or both of a tilt of the document and a position of the document by using the selected detection method;
- and
- a determining step of determining whether an occurring lack of a document exceeds a predetermined acceptable level, when clipping is performed by using a detected rectangle.
