Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing device capable of outputting image information in color.

[Prior Art] In general, in a paint system that displays human-powered images, such as figures, in color, when drawing a picture, a tablet 2 that can detect coordinates electromagnetically and its attached bezel 3 are used as shown in Fig. 3. is used. tablet 2
The coordinates above and the coordinates on a display such as a cathode ray tube display that functions as a monitor correspond at a certain magnification, and the operator can check the manual results by moving Ben 3 on the tablet 2. You can continue drawing while doing so.

When coloring a picture created on CRTI,
As shown in FIG. 4, in the palette display area 6 on the monitor,
A palette 5 with a predetermined color arrangement is displayed, and one color from the palette is manually selected using the tablet 2 and Ben 3 shown in FIG. 3 to determine the color of paint for coloring.

[Problem to be Solved by the Invention 1] However, such an image processing apparatus has various problems as shown below.

(1) When using a portion of the monitor as a palette, the number of colors that can be displayed at one time is limited, and it is necessary to switch and display the color pattern in the palette many times to select the desired color.

This kind of work is extremely troublesome for the workers,
This is one of the causes of significantly reducing work efficiency.

(2) Also, because the palette display is switched, it is not possible to compare one palette set and another palette set at the same time.
Additionally, since the total number of colors is small, it is often difficult to select slightly different colors.

(3) Having a large number of color information as palettes on the memory in the image processing device requires a large memory, which is not practical.

(4) In the image processing apparatus, the output result is often requested as a hard copy by an output device (not shown) such as a color printer as the final output. Also, the processing process,
Confirmation of processing results is performed using CRTI. Therefore,
Ideally, it is desirable that the colors on the CRTI match the corresponding colors on the hard copy. However, in reality, CRT
The fact that the cathode tube of I is a light emitter, (: There are differences in the contrast ratio that can be expressed between RTl and hard copy, differences in linearity indicating the relationship between CRT and hard copy, and differences in color reproduction range) , Generally, CRTI is performed in a dark place.
Due to the difference in viewing conditions in hard copies, it is impossible to perfectly match the colors of the two.

For this reason, there is a problem in that the obtained hard copy output often differs from the image the designer had in mind.

Therefore, an object of the present invention is to solve the drawbacks of the above-mentioned conventional example,
To provide an image processing device that allows an operator to easily and quickly select a desired color and allows the selected color to match the final output color.

[Means for Solving the Problems] In order to achieve such an object, the present invention provides an output means for outputting image information of a color according to a color signal, and an output means that corresponds to the colors that the output means can take. A color information recording medium on which a color sample and color information regarding the color are recorded in advance, a reading means for reading color information from the color information recording medium, and a signal generating means for generating a color signal corresponding to the read color information. It is characterized by the following.

[Function] According to the present invention, the desired color information is read by the reading means by referring to a color sample recorded in advance on the color information recording medium in correspondence with the colors that can be taken by the output means. To provide an image processing device in which a desired color can be easily and quickly selected, and the selected color matches the final output color.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of a configuration in an embodiment of the present invention.

In FIG. 1, 7 is a signal processing section that performs image processing operations, stores the results, controls the entire system, and also serves as an interface with each device. 8

FIG. 2 is an explanatory diagram showing the color sample book 10 in more detail.

In Fig. 2, 14 is a color batch of color samples, and 1
5 is a barcode corresponding to each color batch.

Next, the operation of the embodiment of the present invention will be explained.

The present invention is intended to solve the problems of the prior art by introducing color information from the color sample book 10 shown in FIG.

In order to reflect the intention of the worker, in the present invention,
A color sample book is created using the output of the system's output device. Since the color sample book perfectly matches the output on a one-to-one basis, the operator can obtain the desired output by selecting any color from the color sample book 10.

When creating a color sample book 10, there are various possible arrangements for determining the order of colors, such as lightness, saturation, hue, etc., but it is desirable to use the arrangement with which the operator is most familiar. For example, a plurality of color sample books with the same color arrangement as those sold by printing companies and ink companies may be prepared to widen the range of choices available to the operator.

Next, when the worker selects one color from the color sample book 10,
Color information must be sent to the signal processing section 7 by some method.

Therefore, in the present invention, data for R, G, [1 is recorded in both barcodes and numbers near the color of the color sample book IO, and the barcode is scanned by the barcode reader 11 to obtain color information. of human power is possible. Alternatively, the color used for processing in the signal processing section 7 may be determined by inputting RGB data from a keyboard.

Coding of color information using a barcode is, for example, red (R
), green (G), and blue (B) in this order. When expressing colors with 256 gradations for each color, that is, R:
201. G:20. B: 201Q' for data of 80
A 9-digit number, such as 2GO8Q, can be expressed using multiple combinations of parallel bars and spaces between them. There are various standards for expression methods (for example, 2 of 5, J
It is desirable to follow one of the standards (AN, etc.).

The barcode reader 11 consists of a light source section such as a light emitting element (LED) and a sensor that detects light such as a photodiode, and scans the barcode at a constant speed. Barcode 1
The reflected light from 1 is read as an analog signal and translated into a digital signal by the identification processing section 12.

FIG. 4 is a diagram showing the flow of data in this embodiment. The flow of data will be explained with reference to FIG.

The barcode reader 11 is equipped with a switch, and the operator presses the switch while reading the barcode reader 11.
scan. When the switch is on, control of the signal processing section 7 is passed to the identification processing section 12. The identification processing unit 12 reads the designated colors R and G from the barcode.

The B value is sent to the signal processing section 7. The signal processing unit 7 displays the selected color in the selected color display area 8' on the monitor and simultaneously displays R,
G and B values are also displayed. Then, the color to be used on the tablet Ben 9 is determined based on the R3G and B values of the selected color, and control is transferred to the tablet 9.

While looking at Moeta 8, the worker can freely draw pictures using the tablet and Ben 9 in the selected colors. As a result,
R, G, and B image memories in the signal processing section 7 (for example, 5
12 x 512 pixels x 8 bits) values are also R, G of the specified color.
, can be rewritten as B.

Further, below the barcode, the values of R, G, and B are written as 9-digit numerical values in the order of R, G, and B, for example, 201020080 according to the above example, and the values can be entered manually from the keyboard 9'. Then, the signal processing unit receives the signal and determines the color of the paint.

In this embodiment, the color information is recorded using a bar code and numbers, but it may also be recorded magnetically and read by a magnetic reader.

Further, as other recording means, recording means using light, laser, etc., recording means using unevenness, IC memory, punch holes, etc. may be used.

Furthermore, in this embodiment, as color information, R (red), G
(green) and B (blue), but Y
It goes without saying that color information of one hue (yellow), 1M (magenta), C (cyan), brightness, and saturation may be used.

[Effects of the Invention] As described above, according to the present invention, by having the palette of the paint system in the form of a color sample book and the barcode written thereon, (1) an operator using the paint system can When selecting a color, you can freely select a color from a color sample book, just like in traditional design work, and even those using the paint system for the first time can use it without any discomfort. Can be done.

(2) In the case of conventional paint systems, the number of colors in the internal palette was small, and the range of color selection by the operator was extremely limited, but by using a color sample book, , the number of colors that can be selected can be increased.

(3) Also, even if the paint system has the same number of colors as the color sample book in its memory, the number of colors in the palette that can be displayed at the same time is limited, and the colors in the palette may be changed many times. However, according to the present invention, color selection can be performed quickly.

(4) In the case of conventional paint systems, the number of colors that can be compared at the same time is limited, so it is difficult to select slightly different colors, but this can be easily done with the present invention.

(5) There is no need to store palette color information in the memory in the signal processing unit, which saves memory.

(6) The color desired by the operator and the color of the hard copy obtained as output completely matches, and the operator's intention regarding color is accurately reflected in the output.

This effect can be obtained.
