Title: Image processing apparatus involving shadow detection
Inventor: MIYAGI NORIKO
IPC: H04N1/38
Filed: 2001-11-15
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive apparatus which can avoid generation of an offensive shadow on an output image. SOLUTION: When irradiating an original document to acquire an input image signal, the apparatus detects a shadow generated by a step difference in the thickness direction of the document from the input image signal, and controls image processing operation on the basis of its shadow detection result. A shadow detector 1 detects a shadow (step difference caused by the thickness of the document when the document sheet is placed), and controls an image processor 2 on the basis of the detection result. The shadow detector 1 has a shade candidate pixel detector and a corrector. The shadow detector may have a character feature detector to refer to a character feature at the time of the correction.  The shadow detector 1 controls in such a manner as to detect a shadow accurately as identified from a low-contrast character and to delete the shadow or at least not to emphasize the shadow according to the shadow detection result.
