Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing apparatus having a multi-window display function.

Prior Art Office computers, personal computers, word processors, image editing processing systems.

2. Description of the Related Art Among various information processing apparatuses such as workstations and CAD/CAMs, some are equipped with a multi-window display function for displaying a plurality of windows on a display screen.

As for the multi-window display function of such an information processing device, for example, there are cases where the display screen of the display is divided to display multiple windows, and cases where multiple windows are overlapped and displayed6. In multi-window display,
The topmost window (current window) of the overlapping windows is normally in the active state, allowing the operator to perform editing processing.

Therefore, in conventional information processing apparatuses, in order to distinguish the current window from other windows, window icons are displayed or reversed, and window frame lines are made different, for example, with thick solid lines and broken lines.

However, if the current window and other windows are displayed separately in this way, it is difficult for the operator to understand the current window, which impairs operability.

This invention has been made in view of the above points, and an object thereof is to improve the operability of an information processing device.

Furthermore, in order to achieve the above object, the present invention is provided with window display control means for displaying the current window and other windows with different brightness.

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In this information processing device, window display control means A
When a window is instructed to open, the display information of the previous window is developed as low-luminance information on the frame buffer of display control unit B, and the display information of the newly opened window is expanded as high-luminance information. It is developed on the frame buffer of display control section B.

Thereby, the 1-display control unit B causes the CRTC to display the display information developed on the frame buffer by the window display control unit A.

Next, details of this embodiment will be explained with reference to FIG. 2 and subsequent figures.

FIG. 2 is an external perspective view showing an example of a document image editing processing device as an information processing device embodying the present invention.

This information processing device uses character information as an input device.

It includes a keyboard 1 for inputting various information such as control information, a mouse 2 as a pointing device, and an image scanner 3 for reading original images and the like.

The output bag also includes a CRT display 4 for displaying various information and a laser printer 5 for printing out various information.

Additionally, a floppy disk device (FDD) is used as a storage device.
J6 and a hard disk drive (HDD) 7 are provided in a main body 8 that includes a built-in control section.

FIG. 3 is a block diagram showing the control section of this information processing device.

In this control unit 10, a microprocessor (CPU) 11 consisting of a 16-bit microprocessor, for example, is a circuit that also serves as window display control means A in FIG. Executes various controls according to stored programs.

This processing device employs a disk operating system, and loads programs from the floppy disk @6 into the system area (resident area) of the main memory 12 at startup.

The control unit 10 also has a keyboard interface (I/F) Is for inputting information from the keyboard 1.
, a mouse interface 16 for detecting the moving direction, amount and speed of movement based on the X pulse and Y pulse from the mouse 2, and a scanner interface 17 for inputting read data from the image scanner 6. .

Furthermore, this control unit 10 has a CRT interface 1 which controls the CRT display 4, a printer interface 20 which controls the printer 5, a floppy disk controller (FDC) 21 which controls the FDD 6, and an H
The hard disk controller (HDC) that controls the DD7
)22.

Furthermore, this control unit 10 includes a communication control unit (CCU) 2!1 that controls transmission and reception of information with other communication terminal devices.
It is equipped with

FIG. 4 is a block diagram showing an example of the CRT interface IS.

This CRT interface (CRT controller) 1B
controls the CRT display 4 using a bit map display method.

The main control 31 controls the entire day of this CRT interface.

The bit map memory 32 is allocated as part of the memory access space of the CPU II (see FIG. 3), and is
trl 1 writes data to be displayed on the CRT display 4.

Note that this bit map memory 32 has a capacity for one screen (2 bits/pixel), and each pixel stores data 3 (1, 1) when the brightness is high and data 2 when the brightness is low.
(1, O) or data 1 (o.

(2) When there is no display, it shall be treated as data O (0, O). Of course, in the case of n bits/pixel, different data may be set for each luminance.

The nice play control 35 outputs a command to generate a vector (such as yen 2 w 1 yen) and text (characters) in the bit map memory 32 .

The memory control 34 controls the bit map memory 32.
This is an interface for passing the display data written to the video generator 36 to the video generator 36.

The cursor control 35 generates and outputs cursor data (bit map) to be displayed on the CRT display 4.6 The video generator 36 generates and outputs cursor data (bit map) to be displayed on the CRT display 4.
The display data sent from the cursor control 35 and the cursor data sent from the cursor control 35 are combined and output to the CRT display 4.Next, the operation of this embodiment configured in this way will be explained with reference to FIGS. 8C to do
PU11 first receives a window open instruction,
Modify the window management table of the old current window.

The window management table includes 1, for example, as shown in FIG. Default character font 1-number, number of windows overlapping above 2 number of windows overlapping below, number of windows overlapping above, number of windows overlapping below, etc.

Returning to FIG. 5, after modifying the window management table, the outer frame of the old current window is drawn, and the display information of the old current window is stored as data 2 or 1 at the corresponding address in the bitmap memory (frame buffer) 32.
(Low brightness information) to display in low brightness.

After that, after modifying the management table of the new current window, clear the corresponding display area of the new current window, draw the outer frame of the new current window, and data the information of the new current window to the corresponding address of the bit map memory 32 ( High brightness information) Write in 3 and display with high brightness.

In this way, the current window is displayed with high brightness and the other windows are displayed with low brightness, so not only when there is only one current window at the top, but especially when there are multiple windows at the top. Sometimes the operator can easily know the current window.

That is, for example, as shown in FIG. 7, three windows WII-WI3 are opened.

When the window Wtt is the top window, the current window WIf is displayed with high brightness, and the window WI2. Display window WI3 with low brightness.

In addition, for example, as shown in FIG. 8, four windows W
When windows II to WI4 are open and window WII and window WI4 are both at the top, it cannot be determined which window is the current window.

In this case, both of them can be the current window, but if many such relationships occur, it would be undesirable for hardware such as memory capacity to make all the windows the current window. 2) as the current window.

Therefore, if only one window is set as the current window at this time, and window WI4 is the current window, window WI4 is displayed with high brightness, window WIl, window WI2. Since window WI3 is displayed at low brightness, window W
It is possible to easily know which window is the current window, II or window WI4.

In this way, in this information processing device, the current window is displayed with high brightness, and the other windows are displayed with low brightness.

This allows the operator to easily grasp the current window, improving operability.

Note that contrary to the above embodiment, it is also possible to display the current window with low brightness and the other windows with high brightness, but since it is difficult to see in this way, it is still possible to display the current window with low brightness and display the current window with high brightness. It is effective to display windows with high brightness and other windows with low brightness.

Note that the information processing apparatus implementing the present invention is of course not limited to the one described in the above embodiments, and can be implemented in any of word processors, data processors, office computers, and other information processing apparatuses.

As described above, according to the present invention, the operability of the information processing device is improved.
