To obtain RGB image data and binary image data, display the background image of the background original document and the loop-shaped image of the extracted original document on the display unit, and store the background image in the image storage unit. When the coordinate point of the loop of the loop shape image is designated and input from the operating means with respect to the loop shape image displayed on the display means, the coordinate point of the loop shape is extracted based on the designated coordinate point. The loop-shaped coordinate points stored in the area storage means and the RGB image data of the background document stored in the image storage means are combined to generate a combined image. It allows the shape of the synthesis area a in the arbitrary loop, broaden the selection of the image synthesis,

According to another aspect of the present invention, an image processing apparatus optically reads a background original of a background image and an extracted original of an image having an arbitrary loop shape simultaneously or individually by an original reading means. , RGB image data and binary image data are acquired, the background image of the background document and the loop shape image of the extracted document are displayed on the display unit, and the background image is stored in the image storage unit, and the display unit is displayed. When the coordinate point of the loop of the loop shape image is designated and input from the operating means with respect to the loop shape image displayed on, the coordinate point of the loop shape is extracted based on the designated coordinate point. An image processing device for storing in an area storage means, wherein the loop-shaped coordinate points stored in the area storage means and the RGB image data of the background document stored in the image storage means are stored. Form by generating a composite image, and achieve the object.

Here, the document reading means is a device for optically scanning a document placed on a document table in the main scanning / sub-scanning manner and photoelectrically converting it with a CCD or the like. For example, it is read at a pixel density of 600 dpi. , RGB image data and binary image data are output.

The image storage means stores the RGB image data read by the original reading means as 0-255 data, respectively, and the area storage means stores the polygonal coordinate points designated and input by the operating means. The document reading unit binarizes (“0” or “1”) only the G data of the image data read at 600 dpi, for example 30
Stored as 0 dpi, that is, a set of non-volatile memory that stores 1 pixel as 8-bit data ASIC (Ap
replication Specific Integrated Circuit (ASI
It also functions as C).

In this case, as the data contents of 1 pixel 8 bits, for example, in 0 to 4 bits, the area group number (for identifying each area, that is, area signal), 5
For bit, start / end of area (toggle type), 6bi
At t, closed loop tracking bit, and at 7 bit, original image data (at the above density, "1" has an image, "0" has no image).

The bitmap memory (area signal), the scan image, and the RGB memory output image, that is, the area storing means, the read image of the document reading means, and the output image of the image storing means are all synchronized. .

Further, the display means displays the original image read by the original reading means, for example, 100 dpi × 10.

Then, with the designated coordinate point as the attention point, a process of searching for the presence or absence of loop-shaped coordinate points in a predetermined range around the attention point is sequentially performed by moving the attention point according to a predetermined movement rule. The loop-shaped coordinate points may be extracted and stored in the area storage means.

According to the above configuration, when any one point in the loop of the loop shape image displayed on the display means is designated and input by the operating means, the designated coordinate point is set as the attention point and the attention point Since the process of searching for the presence or absence of the loop-shaped coordinate points in the surrounding predetermined range is sequentially performed by moving the target point according to the predetermined movement rule, the loop-shaped coordinate points are extracted and stored in the area storage means. The loop shape can be easily and appropriately recognized, the functions of image processing can be diversified, and the processing can be easily and appropriately performed.

Is a gate signal to be negated.

According to the above configuration, the loop-shaped image is overwritten on the RGB image data of the background document stored in the image storage means using the area signal indicating the loop-shaped coordinate points stored in the area storage means. Since a composite image is generated by setting the loop shape image on the area storage unit composed of the bitmap memory, the images can be easily combined, and various loop shapes can be easily and appropriately handled. Therefore, the image processing functions can be further diversified.
