First, a boundary of a document is found from data captured by the CCD (step 401). When the boundary of the document is found, a flag indicating the start of the document is turned ON (step 403).

If it is not the boundary of the document, the flag indicating the start of the document is turned off (step 402).

Next, the coordinates of the start or end of the document are recorded (step 404). Next, the paper size is determined from the coordinates of the boundary of the original paper (step 303).

Next, the color of the margin is designated. Next, the area other than the original paper size is changed to the designated color data (step 305).

Next, data is output (step 20).
4). (Embodiment 2) In Embodiment 2, the size of the original paper is searched for the closest standard paper size in the image processing (step 203) of FIG. 2, and the size of the original paper is made the same as the standard paper size. The procedure will be described with reference to the flowchart of FIG. 5 from the recognition of the range of the document to the color conversion of an area other than the document paper area.

First, a readable area of a scanner is read by using a CCD or the like that recognizes a range of a document sheet (step 501).

Next, when the document area is recognized (step 502), the document paper area is calculated (step 50).
3). If not recognized, the range of the document sheet is recognized again (step 501).

Next, the values of the length and width of the smallest standard paper size are set to variables A and B as comparison values (step 5).
03).

Next, in order to compare the values of the length and width of the original sheet with the comparison values of the standard paper, it is checked whether the values of the length and width of the original sheet are smaller than variables A and B (step 504). If the document is large, the vertical and horizontal sizes of the fixed form paper, which is one size larger, are set to comparison variables A and B (step 506). Thereafter, comparison with the original paper size is performed again (step 505). If the original is small, the comparison variables A and B are set to the length and width of the original paper (step 507).

Next, the color of the reading area other than the original paper area is designated (step 508). Next, the color of the reading area other than the original paper area is converted to the selected color (step 509).

(Embodiment 3) Embodiment 3 will be described with reference to the flowchart of FIG. 6 from the recognition of the range of the document to the conversion of the area of the punched hole into a designated color.

First, a readable area of the scanner is read using a CCD or the like that recognizes the range of the original paper (step 601).

Next, when the document area is recognized (step 602), the document paper area is calculated (step 60).
3). If not recognized, the range of the document sheet is recognized again (step 601).

Next, the values of the length and width of the smallest standard paper size are set in variables A and B as comparison values (step 6).
04).

Next, in order to compare the values of the length and width of the original sheet with the comparison values of the standard paper, it is checked whether the values of the length and width of the original sheet are smaller than the variables A and B (step 605). If the document is large, the vertical and horizontal sizes of the fixed form paper, which is one size larger, are set to comparison variables A and B (step 606). Thereafter, the comparison with the original paper size is performed again (step 605). If the original is small, the comparison variables A and B are set to the length and width of the original paper (step 607).

Next, a punch hole database in which the intervals and diameters of the punch holes are registered is fetched (step 60).
8).

Next, a circle matching the diameter of the punched hole in the punched hole database is searched from the manuscript area (step 6).
09).

Next, if there is no match, a circle is searched for a match with the diameter of another punch hole (step 60).
9). If they match, a search is made to see if there is the same circle at a position that matches the hole interval in the punch hole database (step 611).

If there is no match, the process returns to step 608 to search for a new punch hole. If they match, the area of the circle is determined as the area of the punched hole (step 613).

Next, the color of the punch hole area is designated (step 614). Next, the color of the punched hole area is converted into the selected color (step 615).

(Fourth Embodiment) In the fourth embodiment, FIG. 7 shows the image processing (step 203) in FIG. 2 by recognizing the range of the original in FIG. The procedure up to conversion to the same color as the color is shown in a flowchart, and the procedure is described below.

First, the readable area of the scanner is read using a CCD or the like that recognizes the range of the original paper (step 701).

Next, when the document area is recognized (step 702), the document paper area is calculated (step 70).
3). If not recognized, the range of the document sheet is recognized again (step 701).

Next, the values of the length and width of the smallest standard paper size are set as variables A and B as comparison values (step 7).
04).

Next, in order to compare the values of the height and width of the original paper with the comparison values of the standard paper, it is checked whether the values of the height and width of the original paper are smaller than variables A and B (step 705). If the document is large, the vertical and horizontal sizes of the fixed form paper, which is one size larger, are set to comparison variables A and B (step 706). Thereafter, the comparison with the original paper size is performed again (step 705). If the original is small, the comparison variables A and B are set to the length and width of the original paper (step 707).

Next, a punch hole database in which the intervals and diameters of the punch holes are registered is fetched (step 70).
8).

Next, a circle matching the diameter of the punched hole in the punched hole database is searched from the manuscript area (step 7).
09).

Next, when there is no match, a circle is searched for a match with the diameter of another punch hole (step 70).
9). If they match, a search is made to see if there is the same circle at a location that matches the hole interval in the punch hole database (step 711).

Next, if there is no match, the process returns to step 708 to search for a new punched hole. When they match, the area of the circle is determined as the area of the punched hole (step 713).

Next, the color around the area of the punch hole is determined by the CCD.
(Step 714).

Next, the color of the area of the punch hole is determined in step 71.
The color is converted to the color recognized in step 4 (step 715).
