Title: Image processing apparatus
Inventor: YAMAGUCHI TOMOHIRO
IPC: H04N1/40
Filed: 2003-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of discriminating a dot region and characters or the like thereon with high accuracy and applying proper processing to each of the dot area and the characters or the like.  <P>SOLUTION: An isolated point discrimination section detects the presence of an isolated point and discriminates its size. A tentative dot area discrimination section 42 counts the number of detected isolated point signals to decide a tentative dot region. Thus, a region wherein isolated points are dense is selected to be the tentative dot region. An isolated point magnification section 43 magnifies the detected isolated point signal up to an original size to decide a magnification isolated point region. A dot region limit section 44 applies AND logic to the tentative dot region and the magnification isolated point region. Thus, only positions wherein isolated points actually exist among the tentative dot regions are used for the dot processing region. Thus, when characters or the like exist on dots, the characters or the like are not incorporated in the dot processing region.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
