In the start point detection processing, first, the binarized data of the designated coordinate position is acquired from the original BM 5 based on the designated coordinate designated via the digitizer 4 (S1), and whether or not the pixel at the designated point is black (1) ( 0) is determined (S2). Here, when the pixel at the designated point is black, an error code is output to the system control unit 7 as an error (S3), and the process ends. on the other hand,
If the pixel at the designated point is not black, the pixel at the designated point is set as the target pixel (S4), and it is determined whether the pixel on the left of the target pixel is black (S5). If the pixel to the left of the pixel of interest is a black pixel, the pixel of interest at that time is set as the start point, and the coordinates thereof are used as contour information for the system control unit 7.
It is stacked in the internal RAM (S6), and the process ends. On the other hand, if the pixel to the left of the target pixel is white, the position of the target pixel is moved to the left by one pixel (S8), the processing is continued until the address corresponding to the left end of the document (S7), and the black pixel is detected at the left end.

First, the contour start point is designated as a pixel of interest (S11), and it is determined whether the pixel on the right of the pixel of interest is white (S12). When a black pixel is detected in step S12, the first white pixel of the eight adjacent pixels is detected clockwise starting from the adjacent point on the right of the pixel of interest (S13). When a white pixel is detected in step S12, the white pixel before the first black pixel of the eight adjacent pixels is detected counterclockwise starting from the adjacent point on the right of the pixel of interest (S14). If the detection of the white pixels fails in steps S13 and S14, that is, if the surrounding pixels of the eight adjacent pixels are all white pixels or all black pixels (S15), an error code is output to the system control unit 7 as an error. The output is made (S16), and the process ends. However, a pixel once detected as a white pixel is not detected again as a white pixel. If the white pixel is successfully detected (S15), the chain code (see FIG. 11) is obtained from the relative position between the detected white pixel and the target pixel, and the code value is stacked in the RAM as contour information (S10). ). Next, the detected white pixel is set as a new pixel of interest (S18), and step S12 and subsequent steps are repeated until the pixel of interest coincides with the start point (S19). When the new pixel of interest and the start point match, the process ends.

Area data is written to BM71. The area data written here corresponds to the process selected by the operator. Details of a method of designating the processing contents in the area by the operator and the area data filling processing of the area BM 6 will be omitted.

After the writing of the area data to the area BM 6 is completed, the main scan is executed and the original image is taken in again by the image reading section 1.

Although the binarization processing of the read data is performed by the binarization circuit 66, the binarization circuit includes a logic circuit as shown in FIG. It is possible to extract only the data that is displayed.
The comparator (1) 81 compares the input data with the data held by the predetermined threshold value 1, and outputs a high level when the input data is smaller, and the comparator (2) 82 outputs the input data and the predetermined value. The data held by the threshold value 2 of 1 is compared, and when the input data is larger, it becomes a high level output. AND the logical product of both outputs
The threshold value 1 <input data <threshold value 2 can be detected by the circuit 83. Inversion circuit 8
