Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an image processing apparatus, and particularly to multi-window processing.

[Prior art]

Conventionally, multi-window (multi-window means mutually independent image processing areas on one display screen, each image processing area is called a window, these windows perform independent processing,
They can also be displayed mirroring each other. ), temporarily suspend the window that was performing the process,
A new window was formed and a new process was performed.

However, when a new processing window is opened, the previous processing window is hidden, which is inconvenient when executing the previous processing again. Therefore, it is possible to move the window to eliminate the hidden part (it is considered, but if you repeatedly interrupt the window with it open (displayed on the screen), more windows will be displayed on the screen (this is correct). In order to restart a certain process, you have to search for the window you want to restart by reducing or moving the windows of other processes, which is extremely time-consuming and reduces work efficiency. The one shown above is a nice-looking painter.

[Object] The present invention has been made in view of the above points, and is to provide an image processing device that can quickly search for a desired window.

Another object of the present invention is to provide an image processing apparatus that can remove unnecessary windows and create an easily viewable image.

[Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

1 to 6 show a first embodiment of the invention.

FIG. 1 is a block diagram of the device according to this embodiment.

The main memory 1 is used as a work memory for the status of each window and each process, and the window buffer 2 stores the image for each window. It is for controlling. Detects the vertical relationship of windows, synthesizes window buffers, and generates graphic RA (not shown)
Screen composite video control 4 is stored in M and displayed on CRT.
It is. The keyboard 5 is used by the operator to operate windows and perform various processing. The main processor 6 is the above-mentioned tα processor, 721. Window buffer? , the screen control processor 3, the keyboard 5, etc. 7 is a CRT display for displaying characters, graphics, etc. in the window buffer.

FIG. 2 shows an example in which window buffers are combined and a window is displayed on the CRT screen 7.

In this example, the number of windows is three, and the viewport displayed on the screen 7 is shown by diagonal lines. Regarding the vertical relationship of windows, they are displayed in the order of window buffers 1, 2, and 3. ! The windows are updated in the order of 1, 2.3.

In Figure 3: i'When each window is displayed according to the configuration of Figures 1 and 2, the windows for processing A, E, and C are open (displayed). When the operator wants to interrupt window processing and resume processing of window C, the window of C is completely hidden by the windows of A and H, so the operator has to search for the window of C. Conventionally, as shown in FIG. I had to resize or move windows A and B to find window C.

Uninvented is ``If a certain function is instructed, the second
By compositing the window buffer 7 shown in the figure, the viewports of each window are combined with a logical sum and stored in the graphic RAM, so that each window displayed on the screen -A is not made transparent as shown in Figure 5. The operator can immediately select the window for the next operation.

FIG. 6 is a seek/sequence flowchart of the L processor 6 of this embodiment.

In 5TEPI, when the operator operates the keyboard 5, the main processor 6 recognizes the operation and latches it into the main memory 1. 5 In TEP2, it is determined whether or not a window search has been instructed by the operation of the keyboard 5. If a window search has not been instructed, the process instructed in step 1 is performed (STEP 7); if a window search has been instructed, In step 3, the viewports of each window buffer are combined by logical sum using the screen operation processor 3,
The screen is displayed on the CRT 7 via the screen composite video system 1J11 section 4. In 5TEP4, it is determined whether all the windows are displayed, and the process in 5TEP3 is repeated until all the windows are displayed.This determination is made by outputting a pulse every time the data of each window buffer 7 is output to a circuit (not shown). judge by counting them. still.

The method of judgment is not limited to this.

5 In STEP 5, the operator designates a necessary window from among the synthesized windows, and in STEP 6, the designated window is brought to the top and redisplayed. At this time, the logical sum with other windows is stopped so that the data of other windows cannot be seen through.

In the above embodiment, all the window buffers are logically summed, or the data of two window buffers may be logically summed and stored in the graphic RAM for display. Now you can only see data from two windows at a time, making it easier to search for the window you need.

Also, one window is 2! For city i, this window and one of the other windows may be logically summed, and the other window may be changed and displayed at predetermined time intervals.

At this time, once you have searched for the required window, you can receive instructions from the keyboard and immediately bring the required window to the top. This is 5TEP3 of the 6th UA
It is sufficient to insert the judgment of the operator's interrupt instruction between and 5TEP4.

Note that instructions from the operator can be given by a pointing device as well as a keyboard.

Also, conventional multi-window type devices that write black characters on a white background (white J1 is a CRT's luminous point black character is a vanishing point)
Then, if the operator performs a process that lasts a long time, C
Since the number of light points in RT is overwhelmingly larger than the vanishing points, it has the disadvantage of causing eye fatigue. Therefore, when the operator wants to invert the black and white of any window, he or she enters an inversion command from the keyboard or uses a pointing device. When the cursor is moved to the window black-and-white inversion function 9-2 in FIG. is displayed on CRT7J:.

When drawing characters, etc. on the window buffer 7, which has been inverted in black and white, since the background is inverted, the process of turning on the bits must be reversed, such as turning off the bits.

FIG. 7 shows the control flow of the above black and white inversion process.

5TEP50 judges the input instructed by the operator,
5TEP 51 determines whether the input instruction is an instruction for black and white inversion processing. If not black and white inversion, 5TEP50
Processes the input instruction, and if black and white is inverted, inputs the start address of the specified window buffer into the address pointer (STEP 52), and in 5TEP 53, 1'1a of the address pointer is set to the end address of the specified window buffer. Determine whether they are equal or not, and if they are not equal, invert the contents of the address indicated by the 7 trace pointer. If the address contents are 0, set it to l, and if it is ■, set it to O)
STEP 54), Increment the address pointer by one (STEP 55), repeat this process until the address pointer becomes equal to the end address of the specified window buffer, and when they become equal, store the contents of the window buffer in the graphic RAM. , a black and white inverted window is displayed (STEP 56).

As described above, eye fatigue can be alleviated by inverting the entire window in black and white to reduce the light spots on the CRT.

Next, priority of overlapping windows (priority of overlapping degree:): The more windows overlap, the higher the priority, and the priority of the window at the top is displayed as 1. ) to display a hidden window.

is a microprocessor (MPU) that controls the operation of the device.
, 11 is a main memory, 12 is an image display device (CRT), 1
3 is a pointing device 8 which is a cursor, and 9 is a function section which displays various processing commands. 9-
1 is a priority down function that lowers the priority of the window (just above the east) to the maximum (increases the vertical degree), 9-2 is a negative inversion function that inverts the inside of the window in black and white, and 9-3 makes the window transparent. This is a transparent function that overlaps the window immediately next to that window, and these are transparent functions that are determined by the MPU 16 by moving the cursor 8 to the desired function and turning on the human key of the pointing device PD. A desired function is executed by latching the function mode into the main X memory 11. It is also possible to input from the pointing device FD or keyboard.

When bringing a necessary window to the top, it is done by instructing the priority down function 9-1 and bringing the unnecessary window to F.

This priority down processing will be explained along the flowchart of the 10th [N]. 5TEPLO recognizes the position of the cursor on the screen, waits for input at 5TEpH, and if there is an input instruction, determines whether it is Brioitigra 7 at 5TEP12. If the instruction is not from the priority town, other processing is performed (STEP 13).

If the instruction is to lower the priority, the number of the specified window is detected from the cursor position (ST
EP14), and: Detect the priority of the specified window from the example window table shown in the fSII diagram (STEP15).The window table is numbered starting from 1 in the order in which windows are formed on the screen. This register is given priority. The window closest to the window has a smaller value representing the priority.

Note that the number of registers in the window table is the maximum number that can be set for windows.

5TEP 1 In order to search the window table, the start address of the upper and lower degrees of the window table is set in the 7 address pointer. and a priority f+/j greater than the priority value of the specified window
If there is a large priority value, the window number is recorded and the priority is decreased by L (the priority value is increased by one).

Then increment the address pointer by one and check the priorities for all windows (
STEP 17-21).

Then, in 5TEP22, set the highest priority value among the searched priorities as the priority of the specified window (directly.
This is the priority value before the priority is increased by one in P19. At 5TEP23 and 24, the coordinates of the corners of the specified window and the window detected at 5TEP18 (hereinafter referred to as a search window) are detected. and 5
In TEP 25, it is determined whether there is a changed part from the coordinates of the corners of the specified window and the coordinates of the corners of the search window. This judgment method is as shown in FIG.
When QO or XrO<XQl is satisfied, it can be seen that the window is not closed. Similarly, when Y old (Y LO or Y i (O< Y Ll), the window is not positive, so Xrl<X
! Q(1, XrO<XJ21, YHI<YLO.

It can be seen that the windows overlap when neither Y HO < Y Ll is satisfied.

Note that W a and W b represent windows. If there is a rabbit-shaped part as shown in Fig. 13, it is the designated window W.
l? Find the area where the coordinates of the corners of the search window Ws are correct (STEP 26). In the example of Figure 0, there are 4 points (XMI, MHI).

CXrO, Y)il), (Xul, YLI), (X

The part surrounded by YLI) corresponds. Note that information about the hidden portion of the window is stored in the main memory. Then, 5TEP27 stores the data of the overlapping area of the two specified windows in the L memory, and 5TEP
In 28, the data in the area that was the claw of the specified window of VRAML is erased, and in 5TEP29, the data in the area that was the claw of the search window is read from the main 2tQ to the erased area on VRAM, and the 447 items on the VRAM are erased. The data is stored in the specified area. This changes the priority of the specified window and allows you to see the contents of other windows that are hidden behind the specified window.

Also, if -88 of the overlapping windows is also displayed, move the cursor there and press the FD input key.
By selecting N, the priority of that window becomes first, r, , r, <, and it is displayed at the first F of each window, so that the contents can be viewed immediately.

This processing method performs a window table search, lowers the priority value of a window with a higher priority than the specified window by one, and sets the priority value of the specified window to 1.

Then, store the area to the east of the window whose priority was higher than that of the specified window to the ememory, erase the data in VRAM in that area, and read out the data in the specified window in that area from the main X memory in advance and store it in VRAM. It is done by doing.

By changing the window priority as shown below, you can change the window's texture and see the hidden contents of the window.

[Effect] As explained above, according to the present invention, a plurality of mutually independent image processing areas are lengthened and displayed using a logical sum when displayed on the screen, so that a window hidden by another window can also be displayed as a window. You can find it without searching for it using operations such as moving.

Further, according to the present invention, by inverting the state of any image processing area, it is possible to reduce the light spot on the CRT and reduce eye fatigue.

Furthermore, according to the present invention, by changing the overlapping relationship between a plurality of mutually independent image processing areas, the contents of the necessary image processing areas can be immediately known, and unnecessary image processing areas can be removed. .
