In the brightness display section 22b, the extraction range is displayed as a brightness change based on the brightness lower limit value / upper limit value.

The color of the chromaticity designated by the chromaticity setting section 21 is displayed on the brightness display section 22b so that the brightness continuously changes in the vertical direction. The user can specify an arbitrary brightness with the brightness setting switch 22a. The lightness setting switch 22a has a scroll bar configuration like the chromaticity setting switches 21a and 21b, and the user can specify the lightness by the same operation as described above.

Reference numeral 23 denotes a chromaticity range setting unit which includes a chromaticity range setting switch 23a and a chromaticity range display 23b. The chromaticity range setting switch 23a has a configuration of an up-down switch, and the user can specify a chromaticity range (%) by operation. That is, it is possible to use the chromaticity range setting switch 23a to determine what percentage of the chromaticity value above and below the chromaticity value specified by the chromaticity setting unit 21 is to be the desired chromaticity range. In FIG. 5, 5% is specified as the chromaticity range. Although the designated chromaticity range is displayed on the chromaticity range display 23b, a numerical value may be directly input from the keyboard 3 into the chromaticity range display 23b.

FIG. 8 shows the y chromaticity table. This xy chromaticity table is based on the XYZ color system (CIE 1931 standard color system),
The tristimulus values of the B color system are calculated based on the following equation.
It can be converted to a stimulus value.

[0033]

(Equation 1)

Then, x = X / (X + Y + Z) (2) y = Y / (X + Y + Z) (3) z = Z / (X + Y + Z) (4) x, y) can be treated as so-called chromaticity (xy chromaticity),
When x and y are arranged on the horizontal axis and the vertical axis, respectively, an xy chromaticity table as shown in FIG. 8 is obtained. The chromaticity display section 21c displays the xy
The pixels of each color are displayed in an array of a chromaticity table. Since the pixels of each color are arranged to change continuously, the user can easily specify a desired chromaticity.

Next, the operation in the above configuration will be described in detail. In the above configuration, the CPU 7 executes the processing shown in the flowchart of FIG. 6 based on the image data input from the image scanner 4 or the like, thereby extracting the area. The control shown in FIG. 6 is stored as a program of the CPU 7 in the ROM 9 or a storage medium such as a hard disk drive or a floppy disk (not shown).
Shall be supplied. These storage media correspond to the storage media of the present invention.

In step S1 of FIG. 6, first, an area extraction dialog 20 (FIG. 5) is displayed. As shown in FIG. 4, the dialog 20 is always displayed on the sketch 19 (it is assumed that the image is already input from the image scanner 4 or the like). The dialog 20 displays a color matrix formed by using the horizontal chromaticity x and the vertical chromaticity y of the XYZ color system as variables as described above.

In this state, the user operates the chromaticity setting section 21,
The chromaticity range setting unit 23 and the lightness range setting unit 24 specify an area based on chromaticity and lightness. The designation based on the user's chromaticity and lightness is input as follows. Here, from the operation state of the dialog 20, the central value of the chromaticity, the lower limit value (xmin and ymin) and the upper limit value (xmax and ymax) of the vertical and horizontal (x, y), the central value of the lightness, and the Lower limit (Smin) and upper limit (Sma
x) is extracted (specific processing is described later with reference to steps S10, S11, and S12 in FIG. 6).

That is, by setting the center and range of chromaticity in the chromaticity range setting section 23, the horizontal and vertical lower and upper limits of these xy chromaticities are obtained, and the RGB chromaticity is determined as described later. The stimulus sum S is obtained, and the center and the range are set by the lightness range setting unit 24, thereby obtaining the lower limit value and the upper limit value of the lightness.

In step S2, pixels within the set range are extracted from the image data of the sketch based on the set values of the dialog 20.

For example, from the sketch 100 shown in FIG.
By specifying the desired lightness and chromaticity ranges, FIG.
It is possible to extract an image area as indicated by reference numeral 101 at 0. The extracted image area is stored in the RAM 8 as binary extraction data, for example, and the pixels within the set range are displayed brighter and the pixels outside the set range are displayed darker, thereby highlighting the image in the same sketch (or only the extracted part). Another window may be created and displayed separately.)

It is determined whether each pixel of the image data of the sketch is within the setting range of the chromaticity and lightness specified by the user or not.
(Red), G (Green), B (Blue) Stimulus sum S obtained from data
And the chromaticity (x, y) converted to the XYZ color system. This process is shown in FIG.

In the processing of FIG. 7, the image data of the sketch is sequentially scanned to determine whether each pixel is within the setting range of the chromaticity and lightness specified by the user, and control the display of the sketch on the display. Is what you do. Here, the processing of FIG. 7 will be described first.

In steps S21 and S22 of FIG. 7, the counters j and i of the vertical and horizontal pixels are initialized to 0, respectively. As a result, the pixel at the origin of the sketch is indicated.

In the subsequent loop after step S23, first, in step S23, the color stimulus values of the pixels indicated by the counters j and i are read out to the registers R, G and B, respectively.

In step S24, the stimulus sum S of the pixel
Is calculated (S = R + G + B). This stimulus sum S is used as the brightness of the pixel.

Further, the user inputs X
In order to compare with the chromaticity / brightness range specified based on the YZ color system, in step S25, the RGB color system data of the registers R, G, and B is converted into XY using the above-described equation (1).
Convert to Z color system. The horizontal chromaticity x and the vertical chromaticity y of the pixel can be obtained by the above equations (2) and (3).

In steps S26 and S27, it is determined whether or not the chromaticity (x, y) and lightness (stimulus sum S) of this pixel are within the range specified by the user.

That is, in step S26, xmin <x <xmax (5) ymin <y <ymax (6), and in step S27, Smin <S <Smax (7) Is determined.

If the chromaticity and lightness of the pixel are within the range specified by the user in steps S26 and S27, step S
In step 28, 1 is set in the extraction control data, and step S29
Displays this pixel brightly.

On the other hand, if the chromaticity and lightness of the pixel are out of the range specified by the user in steps S26 and S27, 0 is set in the extraction control data in step S30, and this pixel is displayed dark in step S31.

The extraction control data set in steps S28 and S30 is stored in a predetermined area of the RAM 8 (a vacant bit of the RGB data of the pixel may be used) in association with each pixel. When the extraction region is displayed in another window, the processing in steps S29 and S31
What is necessary is just to replace with the process of copying data to the image data area for another window.

In step S32, it is determined whether or not scanning of one pixel in the horizontal direction has been completed for the pixel of the sketch, and if scanning of one line in the horizontal direction has not been completed, it is determined in step S33.
Then, the counter i is incremented, and the process returns to step S23 to continue scanning one line in the horizontal direction.

When scanning of one line in the horizontal direction is completed,
In step S34, it is determined whether or not the vertical scanning (scanning of all lines) of the pixels of the sketch is completed. If the vertical scanning is not completed, the counter j is incremented in step S35 and the process returns to step S22. Then, the next horizontal line is scanned.

As described above, the user can set the dialog 2
Based on the chromaticity and lightness ranges specified by 0,
The region of FIG. 10 can be extracted from the sketch in FIG. 9 and highlighted and displayed brightly (or displayed in another window).

Referring again to FIG. 6, in step S3, the operation of the correction switch 27 is determined. If the correction switch 27 is operated, the image region extracted as described above is manually corrected in step S4. . For example, as indicated by reference numeral 102 in FIG.
To specify the area. Then, the target portion of the designated portion 102 is changed to one with extraction (for example, output as stitching data) or no extraction (not output), or manually correct the contour of the extracted image area. Or other operations. Further, the display of the sketch 101 is updated based on the result of the correction operation.

For example, in the case of the display shown in FIG. 10, only the designated portion 102 is highlighted, or the brightness or color is further changed depending on whether this portion is to be output as stitched data or not. indicate. Alternatively, as shown in FIG.
Alternatively, only the portion 103 corresponding to 2 may be extracted and displayed.

The changed portion at this time is stored in the RAM 8, and after the correction processing, the cancel switch 2 is again set in step S3.
When the operation 8 is detected, the portion changed by the correction switch 27 is restored and displayed again.

In step S5, the OK switch 25 is determined, and if it is not turned on, the operation of the confirmation switch 29 is determined in step S6. If the confirmation switch 29 is on, the process proceeds to step S7, and the sewing shape is displayed on the sketch 19 based on the sewing data created from the currently extracted image area. The display of the sewing shape may be displayed in a window different from the sketch.

In step S8, the cancel switch 2
In accordance with the ON determination of step 6, the display of the sewing shape is deleted in step S9 and the display is returned to the original display.

On the other hand, if step S6 is denied,
In step S10, it is determined whether or not the setting state of the area extraction dialog 20 has been changed. That is, the horizontal chromaticity setting switch 21a, the vertical chromaticity setting switch 21b, the brightness setting switch 22a, the chromaticity range setting switch 23a, and the brightness range setting switch 24 of the area extraction dialog 20
a, It is determined whether or not the setting states of the all range / release switch 31 and the like have been changed, and if these setting states have been changed, the process proceeds to step S13.

If there is no change in the setting of each section in step S10, an image instruction by the mouse 2 is determined in step S11. Here, the sketch 19 or the region extraction dialog 20
If there is an instruction by the mouse 2 in the chromaticity display section 21c of
In step S12, the pixel of the image data corresponding to the designated position is read, and the horizontal chromaticity x, the vertical chromaticity y, and the brightness are calculated from the RGB data. Here, the chromaticity (x, y) and the stimulus sum S are obtained by using the above equation (1). The ranges of chromaticity and lightness are input from the states of the chromaticity range setting switch 23a and the lightness range setting switch 24a.

In step S13, the setting change is reflected and displayed on the dialog 20, the process returns to step S2, and the image data is extracted again and the sketch 19 is displayed. At this time, all range / cancel 3
When 1 is set, the sketch 19 is extracted 100%, and the entire surface is displayed bright.

On the other hand, if the OK key 25 is turned on in step S5, the area extraction dialog 20 is not displayed in step S14, and the sewing color is created based on the extracted data using the display color of the setting display 30 as the thread color in step S15. Shi RA
Store it in M8. Here, a sewing data creation dialog (not shown) is used to create sewing data by a process based on a known sewing data creation program.

When creating sewing data for a plurality of sewing areas, the above processing steps S1 to S15 are repeated. In step S16, the sewing data creation operation is terminated according to the determination of the sewing data creation end switch (not shown).
In step S17, the sewing data in the RAM 8 is read out and written in the memory card 11, and the process is terminated.

As described above, according to the present embodiment, the following excellent effects can be obtained.

(1) The user is allowed to specify a chromaticity range or a lightness range so that a stitch generation area can be extracted from multi-tone and multi-color image data, so that a natural image can be used as a draft. it can.

(2) Since the extraction conditions from the image data can be set separately for chromaticity and lightness, subtle shade changes within the same color tone range can be distinguished and extracted, and beautifully sewn data with a beautiful finish can be obtained. Can be created.

(3) Since the stitch generation area can be automatically extracted based on the designation of the chromaticity range or the lightness range, anyone can easily create the stitching data.

(4) The image area extracted based on the specification of the chromaticity range or the lightness range is displayed so as to be distinguished from other image areas. For example, the highlighted image area in the same sketch image or the extracted image area is displayed. By displaying it in another window, the extraction result of the image area can be visually recognized at a glance, and the working efficiency can be greatly improved.

Nothing else. However, the method of cutting out a desired range of the xy chromaticity table is not limited to this, and any method can be used.

For example, with respect to the differences Δx and Δy from the set values of the chromaticity (x, y), the range in which Δx · Δx + Δy · Δy becomes the predetermined value rr is the set value (x, y) of the chromaticity table.
A circle having a radius r centered on y) is obtained. Therefore, if the user specifies the radius value in addition to the desired chromaticity center (x, y) by an appropriate method, the circular chromaticity range in the chromaticity table can be set. . Of course, if an appropriate calculation formula is used in addition to the circular region, the user can select an arbitrary chromaticity range such as an ellipse.

In the above embodiment, the chromaticity range is specified by using the scroll bar type chromaticity setting switches 21a and 21b. For example, a rectangular or chromaticity range corresponding to the chromaticity range is displayed in the chromaticity display section 21c. , Circles, ellipses, and other shapes,
