Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to specification of brightness and color in an electronic device having a display device such as an LCD or a CRT, or an electronic device such as a projector to which the display device is applied.

[0002]

2. Description of the Related Art Conventionally, when a color is designated, a palette is displayed as shown in FIG. 8, and a color to be designated is picked by a mouse or the like, or a color number assigned to the color is inputted. At that time, if there are few selectable brightness and colors, the total number is displayed on the palette, and if there are many selectable brightness and colors, the representative brightness and color that will be most used by the manufacturer will be extracted in advance. You are creating a palette.

[0003]

In the above conventional example, even when there are many lightnesses and colors that can be selected, only lightnesses and colors prepared in a palette can be used. In addition, there is a problem that the screen is switched once or the pallet is superimposed and displayed on the screen being edited or referenced, so that the screen being edited or referenced becomes difficult to see.

According to the present invention, the lightness and / or saturation of a color can be easily set with a scroll bar, and the lightness or hue actually set can be specified by a palette or a variable color palette according to the user's preference. To specify the desired color quickly and surely while confirming it, and eliminate the need to display a large-sized palette.
The screen can be effectively used for document creation, graph creation, figure creation, etc. When specifying colors, graphs and figures are not hidden by the palette, and colors can be specified while checking actual color figures, etc. An object of the present invention is to provide an electronic device capable of creating a beautiful and well-balanced document or figure that can be created while referring to an image.

[0005]

In order to achieve the above object, a lightness and a color are designated by a scroll bar instead of a conventional palette, and the lightness and the color can be designated by the scroll bar.

By providing the scroll bar as described above, it is possible to easily and reliably specify a color desired by the user for brightness and color.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 2 shows an example of a portable small information terminal.
Is provided with a pressure-sensitive tablet board 3 for inputting or editing with an attached pen 2.

Below the tablet board 3, a menu sheet 4 and an LCD 5 are arranged as shown in FIG.

On the LCD screen, characters and graphics are displayed by input as in Display Example 6.

There are two modes of display, a monochrome mode and a color mode.

In the monochrome mode, a first scroll bar 8, a first cursor 9, and a (variable color) palette 7 are displayed.

Although the first scroll bar 8 is shown on the right side in the figure, it may be displayed on other portions of the LCD 5 such as up, down, left and right.

The first scroll bar 8 is assigned a light color (bright) on the upper side and a dark color (dark) on the lower side, and clicks the first cursor 9 with the pen 2 to display the first scroll bar 8.
When the upper part is slid upward, the brightness of the (variable color) palette 7 becomes the brightness of the density designated by the first cursor 9, and the characters and images to be inputted subsequently have the brightness of the same density as the variable color palette 7. Become.

In the color mode, the first scroll bar 8
And the first cursor 9, and the second scroll bar 10 and the second
The variable color palette 7 is displayed between the cursor 11 and these scroll bars.

The first scroll bar 8 is displayed on the right side in the figure, and the second scroll bar is displayed on the lower side. However, it may be displayed on any of the upper, lower, left and right sides.

The first scroll bar 8 is assigned high saturation and low saturation, and when the first cursor 9 is clicked with the pen 2 and the first scroll bar 8 is slid upward, the variable color is changed. The color saturation of the palette 7 becomes the color saturation designated by the first cursor 9, and the characters and graphics to be input subsequently have the same color saturation as the variable color palette 7.

On the other hand, the second scroll bar 10 has a bright right,
When the left is assigned to dark, the second cursor 11 is clicked with the pen 2 and slides left and right on the second scroll bar 10, and the brightness of the variable color palette 7 becomes the brightness of the density designated by the second cursor 11. Then, the characters and the images to be input next have the same brightness as the variable color palette 7.

As described above, according to the present invention, the color saturation and lightness can be easily set by the scroll bar. Further, since the hue including the lightness actually set can be specifically confirmed according to the user's preference using the variable color palette, the desired color can be specified quickly and reliably. Also, since there is no need to display a large number of palettes such as the conventional 256, for example, the screen can be used for document creation, graph creation,
It can be used effectively for figure creation, etc., and graphs and figures are not hidden by the palette when specifying colors, color can be specified while checking actual color figures, etc., and it can be created while referring to the entire image of the created figure It can create beautiful, well-balanced documents and figures.

The display position of the scroll bar may be displayed at any position regardless of the above, but it is advantageous that the screen can be effectively used at the end as much as possible.

When the "menu" icon on the menu sheet 4 is clicked with the pen 2, a "color change" mode can be designated. In this mode, only the characters and graphics designated by the pen 2 are displayed by the first cursor 9 , The brightness of the specified density is obtained.

Then, the surface of the variable color palette 7 also has the brightness of the density designated by the first cursor 9.

However, when the "color change" mode ends, the position of the first cursor 9 and the brightness of the surface of the variable color palette 7 return to the settings before entering the "color change" mode.

When the "color change" mode is set again, the position of the first cursor 9 and the brightness of the surface of the variable color pallet 7 designated in the previous "color change" mode are obtained.

The "menu" icon has three "color change" modes from 1 to 3, and each mode stores a different density lightness.

On the "menu" icon, there are "standard colors" from 1 to 3, and three patterns of density brightness in the black and white mode can be stored, and the density brightness pattern of the clicked number can be used.

When the user clicks on the surface of the variable color palette 7, the lightness pattern of the density is sequentially changed from 1 to 2, 2 to 3,
Since it changes from 3 to 1, the brightness pattern of the density can be changed without opening the “menu” icon.

When the brightness of the density is designated by using the scroll bar as described above, the scroll bar has a portion that hides the graphic and the character as compared with the conventional method of temporarily switching to the screen displaying the palette as shown in FIG. Since the number is small, the result of the change in the brightness of the density can be confirmed at the same time as the designation.

Since the color mode involves a color control method of the display device, it will be briefly described with reference to FIG.

An LCD or CRT has a color unit as a minimum unit for expressing color and density, and a large number of color units are arranged on a screen. It is said that the more the color units, the higher the screen resolution or the denser the screen.

This color unit also includes several color pixels, and the color pixels are composed of R, G, and B pixels.

R, G, and B produce red, green, and blue, respectively.
Also has lightness of density. In this example, each pixel has 4 brightness,
One color pixel can represent 64 colors.

A color unit composed of four color pixels can theoretically represent about 170,000 colors.

However, in this embodiment, one color pixel is provided in one color unit in order to secure a resolution even on a small screen.

According to the principle of the LCD, three scroll bars are prepared for color adjustment and designation as shown in FIG. 6, R is assigned to the first scroll bar, B is assigned to the second scroll bar,
It is easy to make G correspond to the third scroll bar and adjust the brightness with each cursor. In this case, even if there are four color pixels in the color unit, the R 0th lightness and the R first lightness increase by one, and 256 lightness can be theoretically added to each color.

However, it is generally difficult to imagine a color represented by a combination of functions having three parameters.

This method is unsuitable except for experts, for example, those who sell or design CRTs and LCDs.

Therefore, in this example, learning was performed in elementary and junior high school art time, and two parameters were obtained by substituting a color expression using a color ring and brightness as a familiar color expression method.

The pie chart in FIG. 3 represents a general color wheel. If there are four lightnesses in each color, there are 40 colors. When converting the color ring into a scroll bar, the color ring is divided around the center of red, mimicking the color scheme of the rainbow, and one end is colored red. The other end is where the rainbow or the spectral spectrum will be purple, but in the color circle there is also reddish purple between red and purple, and if there is more color lightness, several intermediate colors are set between them So the other end also ends in red. However, near the red end, a yellowish color is arranged, and near the red end, a purpleish color is arranged.

In this example, the color expression is organized into eight colors and eight lightnesses excluding blue-green and blue-violet, so that there are 64 colors.

Now, in correspondence between the colors produced by the LCD and the color wheel, a table is prepared as shown in FIG. 5 in which the colors and brightness corresponding to the color wheel colors are adapted to the respective combination colors produced by the LCD, and the scroll is made. This is achieved by controlling the LCD color corresponding to the color and brightness specified by the bar.

Accordingly, a memory for storing the compatibility table and software for controlling the LCD in accordance with the memory are installed on the control board of the main body 1.

Also, a method that does not use a matching table is possible by numbering the colors of the color ring and formulating the matching work into a mathematical expression. However, in this example where the number of colors is not so large, the method using the matching table was simple. Further, in this example, the LCD colors are approximated to the numerical values of H, V, and C and replaced. H represents hue and represents "hue", V represents value and represents "brightness", and C represents chroma and represents "saturation".

This expression is a general expression used in JIS in the industry, and the Munsell display color represented by HVC is the most effective in matching the color image with other companies. Similarly, a compatibility table was created.

As shown in FIG. 6, there is also a method of specifying a color with three scroll bars by using the numerical values of the HVC. However, as described above, the three parameters are not adopted because it is difficult to imagine the resulting color. I haven't.

However, the HVC approximate value of the variable color palette 7 or the set color in the "standard color" mode can be displayed as a numerical value. The mode of “HVC value” is prepared in the “menu” mode.

However, there is a problem that the current LCD has a large change in the display screen density depending on the temperature and has a low color reproducibility.
However, when an edited image or the like is output by a color printer, it is effective because colors can be output by data regardless of color changes on the LCD.

When outputting with a color printer, the main unit 1
A matching table is prepared in which the colors of the printer and the printer are correlated.

In this embodiment, the printer 1 is provided with a compatibility table so that the main body 1 does not need to have a compatibility table for various types of printers.

As an example of a method corresponding to the change in the density of the LCD, scroll bars 8B and 10B are provided integrally with the menu sheet 4 as shown in FIG.
There is a method in which only 1B is represented by an LCD.

According to this method, the menu sheet 4 has the advantage that the color reproduction is good because it is a printed matter, and the color does not change even when the temperature changes unlike the LCD.

However, when the scroll bar is displayed on the LCD as in the first example, when the scroll bar is unnecessary,
There is an advantage that it can be used as a display unit of graphics and characters without displaying a scroll bar.

In the color mode, the method of using the "color change" mode and the method of using the lightness pattern having the density of "standard color" are the same. For each, both color and lightness are stored.

As an application of the color expression based on the “HVC value”,
Other color expressions, such as correspondence to color sample numbers of specific manufacturers, replacement of L * a * b * with lightness index and chromatics index, replacement with XYZ tristimulus values, xyz chromaticity coordinates There is a substitution to

Since these are color expressions used in specific specialized fields, they can be handled by preparing a matching table in a memory when commercializing products for specialized fields.

According to the various embodiments of the present invention configured as described above, various effects can be expected as follows.

By specifying the color with the scroll bar, the brightness and the color can be specified in a small space. It is easy to see what level of the entire selection range of elements such as color is to be specified. The use of the two scroll bar methods of color expression and lightness using a color wheel that is easy for the user to understand makes it easier to understand the color. According to the conventional palette method, when the number of intermediate colors that can be specified increases, the number of palettes increases, and a large area of the displayed screen is used for displaying the palette. Although a part or the whole becomes invisible due to the palette, the scroll bar does not hide characters and illustrations, and it is possible to change the color and the like at the same time while selecting an object to specify a color and the like on the screen. For specialized fields,
Various color expression methods can be used.

[0058]

As described above, according to the present invention, the lightness and / or the saturation of a color can be easily set by using a scroll bar. Further, since the lightness or color to be actually set can be specified and confirmed with a palette or a variable color palette according to the user's preference, a desired color can be specified quickly and reliably. Furthermore, since there is no need to display a large-sized palette, the screen can be used effectively for document creation, graph creation, figure creation, etc., and graphs and figures are not hidden by the palette when specifying colors.
The color can be designated while checking the actual color figure and the like, and can be created by referring to the entire image of the created figure, and a beautiful and well-balanced document or figure can be created.
