Abstract

PURPOSE:To prevent the white omission after synthesization and to improve operability by providing a synthesization and display control means, changing brightness in a synthesization original picture area in the picture area after synthesization from other picture areas except said area and displaying them. CONSTITUTION:When the synthesization and display control means A burries and synthesizes the synthesization original picture area in a synthesization destination picture area, said means A synthesizes the picture area with the size of the synthesization destination picture area if the synthesization original picture area is larger than the synthesization destination picture area. Display information on the synthesization original picture area of a synthesization original is developed in the buffer frame of a display control part B with the aid of high brightness information, while that on the part of the synthesization original (synthesization destination picture area - synthesization original picture area) is displayed with low brightness information. This display is developed in the frame buffer of the control part B, which displays the display information developed in the frame buffer by the means A on a CRTC. Thus the white omission after synthesization can be prevented to eliminate the failure of the burry synthesization, and the operability can be improved.

In such an information processing device, for example, a part of the document displayed in the - window (composition source image area) is embedded and composited into a part of the document displayed in another window (composition source image area). can do.

By the way, in conventional information processing apparatuses, when performing such embedding synthesis, a portion of one compositing source image area is copied to the compositing source image area.

At this time, if the composition source image area is larger than the composition source image area, one composite image will have a white spot in the portion of the composition source image area where the composition source image areas do not overlap.

Since it is difficult to make the 1 normal compositing source image area and the compositing source image area the same size, white spots often occur.

In this case, in order to fill in that blank area, you need to redo (
There is an inconvenience that synthesis must be performed using a portion of the compositing source image area (previous compositing source image area) as the compositing source image area.

Next, the operation of this embodiment configured as described above will be explained with reference to FIG. 5 and subsequent figures.

FIG. 5 is an operation flow diagram for embedding synthesis.

To explain this simply, first instruct the opening of the composite light window, and then use mouse 2 to specify the upper left and lower right sides of the embedded area in the opened composite light window, as shown in Figure 6. do.

Specify the compositing source image area.

Thereafter, the user instructs to open one compositing source window, and similarly specifies the compositing source image area.

Then, after instructing execution of the compositing process and causing the compositing process to be performed, an instruction is given to close one compositing source window.

Next, when performing this composition operation, the CPU
The composite display control process executed by the computer will be explained with reference to FIG.

The CPU 11 opens the specified synthesis light window and takes in information on the specified synthesis source image area.

Then, open the specified synthetic light window and
Imports information on the specified compositing source image area.

Thereafter, when execution of 1 composition is instructed, the display information of 1 composition source image area is expanded to the composition source image area on the bit map memory (frame buffer) 32 using data 3 (high brightness information), and the display information of 1 composition source image area ( The display information of the area (composition source image area - composition source image area) is expanded to the composition source image area of the bit map memory 32 as data 2 or data 1 (low brightness information).

As a result, information on one of the image areas after one synthesis is displayed with high brightness, and information on the area (source image area - source image area) is displayed with low brightness.

At the same time, cpUll displays whether or not to erase the display of the low-luminance portion (msu/remain).

Therefore, when the mouse 2 is operated to instruct (erase/keep) (erase), the CPU 1 erases the display of the low-luminance portion.

Then, close the synthetic light window.

This composite display process will be specifically explained with reference to FIG.

First, the window WIl displayed on one screen is set as the synthesis light window, the area P1 surrounded by a solid line of this window W11 is set as the synthesis source image area, and the window WI2
as a synthetic light window.

The area surrounded by the solid line in this window WI2 is defined as the compositing source image area.

Thus, in this case, the combination source image area P2 is a larger area than the combination source image area P1.

Therefore, when embedding and compositing 1 compositing source image area pt into compositing source image area P2, 1 compositing light window W (2) and are simultaneously copied to the synthesis source image area P2 of the 1 synthesis light window WI2.

In other words, the relationship between each area in this case is 1 destination image area P2 = (source image area PI (■) 10 areas ■), and 1
Area ■ in destination image area P2 = source image area Pl
, Similarly, area ■=territory area.

Therefore, the area (3) will not become blank in the image area after composition.

Then, among the image areas after one combination (same as the combination source image area P2), the area (2) which is the combination source image area PI is displayed with high brightness, and the other area (2) is displayed with low brightness.

Therefore, the operator can easily grasp the combination source image area among the image areas after one combination.

Based on this, the operator determines whether or not to erase the area (■).

In this way, in this information processing device, when embedding and compositing one compositing source image area into a compositing source image area that is larger than the compositing source image area, the compositing source image area is synthesized in the size of the compositing source image area, and one image area after compositing is performed. The combination source image area and other image areas are displayed with different brightness.

As a result, even if the source image area is larger than one source image area, the area (source image area - source image area) will not become blank after one combination, and embedding failure will not occur. Improves operability.

Note that, contrary to the above embodiment, the compositing source image area is set at low brightness,
Although other areas can be displayed with high brightness, it is difficult to see in this way, so it is still more effective to use the above embodiment.

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 explained above, according to the present invention, the operability of the information processing apparatus is improved.
