TECHNICAL FIELD OF THE INVENTION
The present invention relates to a color image processing apparatus and a method for displaying a current position indicator used therein, and more particularly, to a method for displaying a current position indicator image indicating a current position of a mouse cursor or a current position in a line on an image displayed on a screen. .
[0002]
[Prior art]
2. Description of the Related Art Conventionally, in a color display device, a display control device that displays drawing data such as characters and drawing lines on a color display device uses one or more types of drawing data based on the background color of a display area for displaying the drawing data. A display color first setting unit for setting a display color is provided (for example, see Patent Document 1).
[0003]
Thus, in the conventional color display device, the display color of the drawing data such as characters and drawing lines displayed on the screen is set so as to be conspicuous with respect to the background color, so that the drawing data of the characters and drawing lines are displayed. It is possible to prevent a drawback that the drawing data is difficult to see due to the similar color between the color and the background color, and it is possible to reduce the work load for the user to set the color of the drawing data. Therefore, in the conventional color display device, it is possible to prevent a drawback that drawing data such as characters and drawing lines displayed on the screen is difficult to see.
[0004]
In addition, in the conventional display device, not only the position of the cursor but also the speed of the cursor is obtained from the amount of displacement of the mouse, and when the user wants to grasp the position of the cursor, the operation of quickly moving the mouse as a signal operation to the computer. Then, when the moving speed exceeds a predetermined speed threshold value, a display emphasizing process for emphasizing a cursor image is performed (for example, see Patent Document 2).
[0005]
This emphasizing process is, for example, a process of enlarging the display size of the cursor, a process of changing the color to a complementary color of the background, a process of increasing the luminance difference between the background and the cursor, or a combination thereof. As a result, in the conventional display device, it is possible to solve the problem that the visibility of the cursor is reduced due to the relative reduction of the cursor size accompanying the higher resolution of the display device.
[0006]
Further, in a conventional image processing apparatus, in a designated position display method for displaying a cursor or a line on a screen to designate a desired position of an image displayed on the screen, a frame memory for storing an image, An overlay memory for storing images in an overlapping manner and a control device for changing the brightness of a cursor stored in the overlay memory are provided (for example, see Patent Document 3).
[0007]
In this conventional image processing apparatus, a control device reads out image data at a position where a cursor or a line is displayed from a frame memory, obtains the brightness of an image at the position from the read image data, and when the brightness reaches a reference value. Is changing the brightness of the cursor or line when As a result, in the conventional image processing apparatus, it is possible to always make the cursor and the line easily visible regardless of the brightness and color of the background image.

[Problems to be solved by the invention]
In the conventional image processing apparatus described above, in the case of the methods described in Patent Documents 1 to 3, although the indicator image of the current position can always be easily viewed, the current position in the mouse or the line displayed on the color display device can be improved. In order to prevent such a problem that the indicator image is difficult to see, a mechanism for automatically grasping the state of the background color such as a chameleon is required, and there is a problem that control becomes complicated.
[0010]
Therefore, an object of the present invention is to solve the above-described problems and prevent a problem that a mouse or a current position indicator image in a line displayed on a color display screen is difficult to see without requiring complicated control. It is an object of the present invention to provide a color image processing apparatus and a current position indicator display method used therefor.
[0011]
[Means for Solving the Problems]
A color image processing apparatus according to the present invention is a color image processing apparatus that displays an indicator image indicating a current position on a color display screen, wherein a plurality of lines having different colors are in contact with each other. The image processing apparatus includes a creating unit that creates an image, and a display unit that displays the indicator image created by the creating unit on the color display screen.
[0012]
The present position indicator display method according to the present invention is a current position indicator display method of a color image processing apparatus that displays an indicator image indicating a current position on a color display screen, wherein a plurality of lines having different colors are used. The method includes the steps of creating a multilayer line that is in contact with each other as the indicator image, and displaying the created indicator image on the color display screen.
[0013]
That is, the color image processing apparatus of the present invention creates a single line in the form of a so-called rainbow-like striped pattern in which lines of different colors are in contact with multiple layers, and configures the multilayer line as an indicator image of the current position. By having colored striped line creation means to make lines, at least one of the multilayer lines is clearly visible in any situation of background color.
[0014]
For example, in the case of a two-layer line, "black" and "yellow" are used. In the case of a three-layer line, three colors such as “R (red)”, “G (green)”, and “B (blue)” are used. The above stripe pattern is usually parallel to the line direction, but may be an oblique pattern or a vertical pattern.
[0015]
As described above, in the color image processing apparatus of the present invention, the colored stripe pattern line creating means is applied to the line or the contour line of the indicator of the current position, and if the colored stripe pattern line is used, the background color of the current position is Regardless of how it changes or how it changes, at least one of the colors of the lines forming the striped pattern is close to a complementary color relationship with the background color, producing an effect that makes the lines stand out.
[0016]
As a result, in the color image processing apparatus of the present invention, the final position when a text sentence is input to the graphic line at the current position of the mouse, the vertical line (blinking) within the line where the mouse is clicked, or the line The vertical line or the like can always be in an easily viewable state.
[0017]
Thus, in the color image processing apparatus of the present invention, the performance degradation due to the control processing is smaller than before, and it is possible to prevent a problem that the mouse or the indicator image of the current position in the line displayed on the color display screen is difficult to see. As a result, the recognition rate of the image of the cursor position by the operator can be improved.
[0018]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a color image processing apparatus according to one embodiment of the present invention. In FIG. 1, the color image processing apparatus according to one embodiment of the present invention comprises a colored stripe pattern line creating means 1, a current position indicator image display section 2, and a color display apparatus 3. Note that, in the color image processing apparatus according to the embodiment of the present invention, a portion for processing an image (text, photographic image, or the like) actually displayed on the color display device 3 is known, and the configuration and operation will be described. Is omitted.
[0019]
The colored striped pattern line creating unit 1 creates a colored multilayer line by contacting and combining a plurality of colored lines, and outputs the colored multilayer line to the current position indicator image display unit 2 as a current position indicator image. The current position indicator image display unit 2 displays the current position indicator image created by the colored stripe pattern line creating means 1 on the color display device 3.
[0020]
That is, the current indicator image display unit 2 displays the indicator on the color display device 3 based on an external instruction (including an instruction from an information processing device (not shown) connected to the color display device 3). At this time, a colored multilayer line is obtained from the colored stripe pattern line creating means 1 and the indicator image thereof is displayed on the color display device 3. In this case, the colored stripe pattern line creating means 1 may be realized by software or may be realized by hardware.
[0021]
Here, the indicator image of the current position is an indicator of the current position, which indicates a specific position on the display screen to be noticed on a display of a personal computer or an OHP (Overhead Projector) display at the time of presentation. An image that is a blinking or non-blinking vertical line in a text line, a vertical line at the position marked by clicking the mouse, the current position of the mouse, or the tip of a pointer at the commentary position held by the commentator for OHP. Indicates a finger mark or the like.
[0022]
In the present embodiment, the current position indicator image is displayed in any color background so that a person watching the screen can always instantaneously grasp the position of the current position indicator. The indicator image is composed of stripe lines of a plurality of colors so that it can be grasped.
[0023]
For example, when the mouse is moved within a text character, the indicator image at that position currently employs a black vertical line (a shape close to the capital letter I in the alphabet). In this case, the character color is black. In the case of a character with high density, the indicator is difficult to see, and a so-called "crow in the dark night" state occurs.
[0024]
In order to avoid this situation, a line in which light color lines of a plurality of wavelengths whose light color wavelengths are greatly different from each other are integrated into a multilayer is adopted as a line constituting the position indicator. As a result, no matter what the current background color is, there is a color close to the relationship between the background color and the complementary color in any one of the light lines in the indicator, so that the human eye has no background. The "complementary color effect", which competes with the colors and appears to stand out from each other, is always established, and the position can be always grasped.
[0025]
As this multi-layer line, "black" and "yellow" are assumed for two layers, and RGB (red, green, blue) or (red, yellow, blue) or the like is assumed for three layers. In the case of seven layers, the color is a rainbow color or the like. This multi-layer wire is realized by contacting a line having a very small line width. This implementation may be implemented using a dedicated hardware mechanism. The above stripe pattern is usually parallel to the line direction, but may be an oblique pattern or a vertical pattern.
[0026]
FIG. 2 is a diagram showing a configuration example of a current position indicator according to one embodiment of the present invention. In FIG. 2, the current position indicator according to the present embodiment is an example of a line in which a conventional single line color current position indicator line is formed into three layers.
[0027]
In the case of the example shown in FIG. 2, each of the vertical lines of red (R), green (G), and blue (B) having a width of 1/3 (W / 3) of the width W of the original black vertical line was touched. The shape is replaced by one to form one colored multilayer line.
[0028]
As described above, the present embodiment is a system in which the one for the band and the one for the task are simultaneously prepared in a fixed manner (system unique), and it is possible to cope with the situation no matter how the situation changes. Further, in this embodiment, a sensor function for a background color such as a chameleon is not required at all.
[0029]
FIG. 3 is a flowchart showing the operation of the color image processing apparatus according to one embodiment of the present invention. The operation of the color image processing apparatus according to the embodiment of the present invention will be described with reference to FIGS.
[0030]
The current position indicator image display unit 2 displays a blinking or non-blinking vertical line in the text line, a vertical line at the position where the mouse is clicked and marked, the current position of the mouse, or the commentary position held by the commentator for the OHP. When there is an indicator request to display a finger mark or the like at the tip of the indicator rod (step S1 in FIG. 3), a colored multilayer line (see FIG. 2) of a previously designated pattern is created as a current position indicator. The created colored stripe pattern line creating means 1 is notified (step S2 in FIG. 3). In this case, the pattern of the colored multilayer line can be selected when the user gives an instruction, or can be selected from a plurality of patterns in advance.
[0031]
Further, the current position indicator image display unit 2 confirms the display position of the current position indicator designated from the outside and sets it as the current position (step S3 in FIG. 3), and displays the current position on the display screen of the color display device 3 as: The created current position indicator is displayed (step S4 in FIG. 3).
[0032]
On the other hand, the current position indicator image display unit 2 determines whether the external instruction is a movement of the current position indicator (step S5 in FIG. 3). The current position is set (step S6 in FIG. 3), and the process returns to step S4 to display the created current position indicator.
[0033]
When determining that the current position indicator is not moving, the current position indicator image display unit 2 determines whether or not the current position indicator is to be erased (step S7 in FIG. 3). Then, the current position indicator displayed at the current position on the display screen is deleted (step S8 in FIG. 3).
[0034]
The current position indicator image display unit 2 determines whether or not the display processing has ended after the erasure of the current position indicator or when it is determined that the current position indicator is not erased (step S9 in FIG. 3). If the current position indicator image display unit 2 does not end the display processing, the process returns to step S1 to display the next current position indicator, and if the display processing has ended, the above processing ends.
[0035]
As described above, in the present embodiment, the lines constituting the current position indicator image are created by multilayer lines composed of different light colors, and for any background color, a color close to a complementary color to the background color is created. By giving them, the "complementary color effect" that makes the colors stand out works, and the indicator is always easy to see, so it is difficult to see the mouse and the indicator image of the current position in the line displayed on the color display screen Can be prevented.
[0036]
In the conventional indicator display method for making the indicator image easier to see, the color of the line of the indicator image at the current position is changed to a color close to a complementary color with the background color while keeping the line color as a single color. Therefore, it is necessary to automatically change the color of the line to the complementary color of the background color or to provide an interface with the user and change the line color, which is a system overhead.
[0037]
On the other hand, in the present embodiment, there is no need to measure the background color, almost no overhead occurs, and the mechanism simply uses the current function in software, which simply bundles a plurality of lines of different colors. Since the indicator image can be simply realized, the indicator image can be easily viewed by a very simple process. However, in the present embodiment, when realizing a colored multilayer line in hardware, it is necessary to reinforce the hardware and newly set an interface with software.
[0038]
【The invention's effect】
As described above, according to the present invention, in a color image processing apparatus that displays an indicator image indicating a current position on a color display screen, a multilayer line in which a plurality of lines having different colors are in contact with each other is created as an indicator image. By displaying the created indicator image on the color display screen, it is difficult to see the mouse and the indicator image of the current position in the line displayed on the color display screen without requiring complicated control. Such an effect can be prevented.
