This can be realized by incorporating software for a color designation function according to the present invention into software.

In the example shown in FIG. 1, a state in which a color designation window 100 is displayed on the screen of the display 10 is shown. The color designation window 100 includes a color list display area 110 for displaying a list of already registered colors, and a color registration area 120 used for newly registering a color. On the other hand, a state where various objects to be allocated are allocated beside the color specification window 100 is shown. In the illustrated example, the graphic 210 and the character string 220 expressed on the printed material are located at predetermined positions. The allocated state is shown. More specifically, FIG.
Is composed of a circle 211 and a triangle 212, and the character string 220 is a character 22 assigned in two columns.
1 and a ruled line 222 between steps.

The color designation window 100 is a window for performing a coloring process on the above-mentioned individual allocation objects, that is, a circle 211, a triangle 212, a character 221, a ruled line 222, and the like. 10 can be displayed on the screen. The actual coloring process is performed by selecting a desired object to be colored from among the objects to be allocated on the display 10 with a mouse, and selecting one of the predetermined registered colors displayed in the color list display area 110. Can be performed by selecting with a mouse. Further, the operator can newly register an arbitrary color using the color registration area 120. Less than,
The process for specifying the color will be described in detail.

FIG. 2 is an enlarged view of the color designation window 100. As described above, this color designation window 100
Inside, a color list display area 110 and a color registration area 120 are provided. The color list display area 110 is an area generally called a color palette, and a plurality of registered colors are displayed as a list. The operator can select the color by moving the mouse pointer over the desired color on the list and clicking the mouse. As described above, the software provided in the computer 20 and functioning as the color specification device according to the present invention includes a color specification window 100 including a color list display area 110 for displaying a list of registered colors.
Function as a window display means for displaying the color list on the display screen, and the color list display area 11
The mouse pointer is moved to an arbitrary position within 0, and the pointer functions as a color designation input unit for inputting an instruction to select a specific color.

A feature of the present invention is that a color sample for each registered color and a numerical value indicating the ratio of each primary color component constituting the color are displayed in the color list display area 110. It is in the point which did. As shown in FIG. 2, in the color list display area 110, columns for displaying a color sample a and a component value b are provided. Here, the component values b are displayed in CMY, respectively, as described in the entry column c.
The primary color K (strictly speaking, K is not included in the three primary colors, but here, for convenience, the four ink colors CMYK used in general printing are referred to as the four primary colors). The numerical value indicates the ratio of each component (a value of 0 to 100% is taken for each primary color). In this embodiment, an arbitrary color obtained by mixing four types of primary colors CMYK on a display Can be specified.

In the display form of the color list in the color list display area 110, a color sample for one color and a numerical value indicating a ratio of each primary color component constituting the color are displayed on the same line. , And a plurality of colors are displayed by changing the lines. For example, in the first row of the drawing, the colors displayed in the color sample a are CMY
A component value b of each primary color component of K is shown. Specifically, C: cyan = 100%, M: magenta = 0%, Y:
The color components of yellow = 0% and K: black = 0% are specified. Usually, the colors displayed on the display screen are composed of mixed colors of the three primary colors RGB of light. Therefore, the color presented as the color sample a is the four primary colors CMYK of the color indicated by each component value b. Does not completely match the color composed of the mixed colors of In that sense, the colors presented in the first line of the color list display area 110 are: C: cyan = 100%, M: magenta = 0%,
Y: Yellow = 0%, K: Black = 0% is a mixed color of color components indicated by numerical values, and the color on the color sample a is a color presented for reference. Therefore, when one color is selected from the color list display area 110, a specific color in which the ratio of each primary color component is specified by a strict numerical value can be accurately specified.

In the example shown in FIG. 2, the color list display area 110
The registered colors are presented in five lines in the table, and at present, a total of five colors shown in each of these lines are registered. As will be described later, the operator can newly register an arbitrary color by performing a predetermined input to the color registration area 120. Since one color is displayed in one line, all registered colors are displayed in the color list display area 110.
If all the information cannot be displayed at one time, the information in the color list display area 110 can be scrolled up and down by clicking the scroll arrows 111 and 112 with the mouse or by dragging the scroll bar 113 with the mouse. Can be done.

In order to select one of the registered colors presented in the color list display area 110, an operation of designating a specific line with a mouse pointer may be performed. For example, FIG.
When the mouse pointer P is moved to the second line and the mouse is clicked at this position, the second line is inverted as shown in FIG. In this case, the operator sets C: cyan = 0%,
This means that a color consisting of a mixture of the four primary colors of M: magenta = 100%, Y: yellow = 0%, and K: black = 0% is designated. As described above, it is very important to specify a color while accurately grasping the color component value of each primary color when specifying a color on a commercial print. With a method of simply displaying and selecting only a color sample as in a conventional color designating apparatus, it is not possible to accurately grasp the color component values of each primary color.

In this embodiment, an object on the display 10 can be colored with a designated color by the following method. First, a predetermined object is selected on the display 10 by a mouse click. Subsequently, one of the target specifying buttons 131 to 134 arranged in the upper right of FIG. 3 is selected by clicking the mouse, and finally, a specific line in the color list display area 110 is selected by clicking the mouse. The coloring of the object with the designated color is completed. Here, the target specifying buttons 131 to 134 are buttons for specifying which part of the target object is to be colored. Specifically, the target specifying buttons 131 to 134 are, respectively, characters and columns. Functions as a button for specifying a ruled line, a graphic frame, and the inside of a graphic (colored by a flat screen).

For example, when the object identification button 131 is clicked in the state where the character string 220 is selected from the objects shown in FIG. 1, the character 221 itself is colored. Specific button 132
When the button is clicked, coloring is performed on the ruled line 222 between steps. When the target identification button 133 is clicked in a state where the circle 211 is selected, the outline of the circle 211 is colored, whereas when the target identification button 134 is clicked, the inside of the circle 211 is displayed. Are colored by a flat screen. The actual coloring process is performed when the operator clicks the OK button 140, and the cancel button 1
If the user clicks on 45, the coloring process is canceled.

In this embodiment, a color having an arbitrary color component can be newly registered using the color registration area 120. FIG. 4 shows that the operator sets C: cyan = 30%, M:
It is a figure which shows the state which is performing the operation | work which registers the new color which consists of a mixture of four primary colors which are magenta = 50%, Y: yellow = 100%, and K: black = 0%. Color registration area 1
As shown in the figure, input fields 121 to 124 for inputting numerical values indicating the proportions of the respective primary color components are provided in 20, and the operator inputs desired numerical values in these input fields. , Each primary color component value of a new color can be designated. The numerical value input to each of the input fields 121 to 124 may be performed using a keyboard, or may be performed by clicking the up and down arrows displayed on the right side of each input field with a mouse to increase or decrease the numerical value of the input field. You may. In the mixed color display column 125, a color sample obtained by mixing the four primary colors based on each component value input in each input column is displayed. As described above, since the color display on the display screen is usually performed using the three primary colors of RGB, the color displayed in the mixed color display column 125 is not always an accurate color, but is used as a guide to some extent. Can perform functions.

When the respective component values of the desired color to be registered are determined by the input to the color registration area 120, the registration button 150 may be clicked. FIG.
By clicking the registration button 150, the sixth
It is a figure showing the state where registration of the 2nd color was completed. The currently registered color is displayed on the sixth line in the color list display area 110. Thereafter, this color can be selected as one of the registered colors. As described above, in the color specifying device according to the present invention, by specifying individual color component values,
Accurate colors can be registered.

As new colors are registered one after another, it becomes impossible to display all registered colors in the color list display area 110 at one time. In such a case, as described above, the information in the color list display area 110 can be scrolled up and down using the scroll function. However, if colors that are frequently used are registered at positions separated from each other, the frequency of the scroll work increases, and the work efficiency decreases. Therefore, in the color specifying device according to the present embodiment, an instruction to change the position of a specific line in the color list display area 110 can be input by a mouse pointer, and the display order of each color is changed based on the change instruction. I am trying to change it.

More specifically, as shown in FIG. 6, the fifth line in the color list display area 110 is pressed with the mouse to select it (highlighted). When the pointer P is moved upward, an index line indicated by a broken line in the figure is also moved upward together with the mouse pointer P. The index line indicated by the broken line indicates the movement destination of the selected row (the fifth row in the illustrated example), and the position shown in the figure (between the first row and the second row). When the mouse button is released at (position), the contents of the old fifth line move to the second line as shown in FIG. 7, and the contents of the old second to fourth lines repeat one line at a time. Will go down. This operation is a so-called drag-and-drop operation, and an arbitrary line can be moved to an arbitrary position. With this feature,
For example, registered colors that are frequently used can be arranged continuously upward. As a result, the frequency of the scroll operation can be reduced, and the operation efficiency can be improved.

Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to this embodiment, and can be implemented in various other modes. In particular, in the above-described embodiment, an example is shown in which the present invention is applied to an assignment processing device for DTP, but the present invention is applicable to any device that needs to specify a color on a display screen. In the above-described example, the pointer on the display screen is moved by the mouse, but the operation of moving the pointer can be performed by an input device such as a trackball or a keyboard.

[0026]

As described above, according to the color specifying apparatus of the present invention, accurate color specification can be efficiently performed.
