Image processing system

An image processing system comprising:

• input means for inputting, as dot information, document information including a plurality of lines comprising character strings;
• removing means for comparing the height of dot information corresponding to respective ones of said lines with a predetermined value, and, in the case that the height is smaller than the predetermined value, for designating the line as spurious and for removing the line;
• calculating means for generating and outputting histogram data of the dot information of the document information from which the designated line has been removed by said removing means;
• detecting means for detecting a base line of each of the character strings in response to a frequency average and a standard deviation of the histogram data outputted from said calculating means;
• and
• processing means for changing the structure of the character strings of the document information using the base line detected by said detecting means as a reference.

• and
• processing means for editing the structure of the character strings of the document information using the base line detected by said detecting means as a reference.
