摘要：PROBLEM TO BE SOLVED: To minimize an influence on image quality even when erroneous determination of image area separation occurs. SOLUTION: In S902, attributes are acquired for the surrounding pixels to be utilized for blurring processing. In S903, it is determined whether or not high priority is assigned to the attributes acquired in S902, and in the high priority, attribute information is stored in S904. In S906, the blurring processing is executed only attributes of pixels with the attributes to which the high priority existing in the surroundings is assigned by performing averaging using only the attribute information stored in S904. Averaging processing is applied for every attribute to find out Er, Dr, Br described in the equation 3: V(SIG)=E(SIG)×Er+H(SIG)×Dr+H(SIG)×Br. In S907, the attribute information is updated by performing overwrite by a result by performing the blurring processing in S906. Thus, the attribute information is not simply expressed by one kind of attribute such as "characters", but becomes multiple value data expressed in ratio of a plurality of attributes such as 70% of characters, 20% of dots, and 10% of grounds.
