Claim 8
Dependent Claim
51 words
A document processor according to claim 4, wherein said storing means stored in the memory data relating to horizontal lines constituting a part of the table, data representing cells constituting part of the table, and character data such as characters present in each of the cells constituting part of the table.
Claim 9
Independent Claim
155 words
A method of recognizing a table in document information, comprising the steps of: searching for the left-hand top edge of the table in the direction of lines in the document information; searching for at least information on the right-hand top edge of the table in the direction of lines in the document information after the left-hand top edge is searched; searching for at least information on the right-hand bottom edge of the table downwardly from the same position as the right-hand top edge in the direction of the lines after information on the right-hand top edge of the table has been searched; the step of searching for at least information on the right-hand bottom edge of the table including the step of searching the left-hand top edge of the table again from the position of the searched right-hand top edge information when information other than that representing the right edge of the table is identified.
Claim 10
Independent Claim
155 words
A method of recognizing a table in document information, comprising the steps of: searching for the left-hand top edge of the table in the direction of lines in the document information; searching for at least information on the right-hand top edge of the table in the direction of lines in the document information after the left-hand top edge is searched; searching for at least information on the right-hand bottom edge of the table downwardly from the same position as the right-hand top edge in the direction of the lines after information on the right-hand top edge of the table has been searched; the step of searching for at least information on the right-hand bottom edge of the table including the step of searching the left-hand top edge of the table again from the position of the searched right-hand top edge information when information other than that representing the right edge of the table is identified.
Claim 11
Dependent Claim
40 words
