Then, these coordinates x and y and the pattern image PG are
In association with the pattern image multiplied by m in both x and y directions
The density value at point P is determined. At this time, for example, the magnification m is
If it is “0.5”, as shown in FIG.

And store it in the pattern memory 220.
You can also. In this case, the password shown in FIG.
The turn input process is executed by the first CPU 201a.
It is. In FIG. 18, first, the switch SW3 is turned on.
Is checked (step # 4001), and the coordinates (x
(3, y3) is input (step # 4002). Soshi
Wait for a key operation to instruct the start of reading (step #
4003). When the reading scan is started, the pixel being scanned is
Coordinates (α, β) are obtained, and the coordinates (α, β) are
Coordinates in F1 (x3 ≦ α ≦ x3 + a and y3 ≦ β ≦ y3
+ B), the density is calculated from the B, G, and R image data D1.
Calculate the value ID and store the result in the pattern memory 220
(Steps # 4004 to # 4006). The density value ID is calculated by setting the visibility sensitivity constant to γ.
B, γG, γR, and the sensitivity of the CCD image sensor 80
Equations (6) where the degree constants are expressed as δB, δG, δR
U. ID = γB × δB × D1B + γG × δG × D1G +
γR × δR × D1R (6) It should be noted that a cloth is used in place of the
You can also store fabric patterns as pattern images
You. In addition, image data from video cameras,
Communication of image data created by a computer
Import via storage media such as cable or IC card
Only, convert it to B, G, R data and store it
Is also good. Especially when using storage media such as IC cards
Attaches a sample of the pattern image to the storage medium
And convenient for storage and use. In the above embodiment, the pattern memory 2
20 includes designs for various fields such as architecture and clothing.
Patterns useful for creating patterns can be stored.
The number and types are not limited. [0124] According to the present invention, a pattern is partially applied.
Images can be easily obtained, and various design images can be created.
When used for development, speeding up design work and labor
Can be reduced.Moreover, diversifying images
Can be [0125]
