Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image editing device equipped with a moving editing function.

[Conventional technology]

When moving specified image data, conventional image editing devices display only the moved image or only a frame representing the size of the moved image on a display device in real time.

[Problem that the invention is trying to solve]

However, in the conventional device described above, only the moving image or only a frame representing the size of the moving image is displayed, so if the moving image and the images below and around the moving image are similar (for example, a whitish When moving an image on a whitish image), there are problems such as it is difficult to identify the area of the moving image, and if only a frame representing the size of the moving image is displayed, it is difficult to see the image after the movement. there were.

[Means for solving the problem (and action)] The present invention has the following features:
This was done to solve the above problem, and by having a means for displaying a frame around the above area to clearly indicate the area of moving image data, it can be displayed as image data with a frame within the displayed image. It is designed so that it can be moved.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

R that stores programs related to image processing of the PU20
It's OM. A RAM 23 is used as a work area for the CPU 21 and as a buffer for temporarily storing data read from the scanner 2 or an external storage device. It is used to store data necessary for processing such as creating area information, which will be described later. Further, 24 is a VRAM that develops images displayed on the display device 3. 25 is a memory management unit (MMU)
These ROM22, RAM23, VRAM
It manages 24.

26 is a rask operation unit that controls the rotation, movement, etc. of the displayed image (the image developed in the VRAM 24), and 27 is an interface circuit that controls data exchange with the scanner 2 and printer 8.

FIG. 3, FIG. 4, and FIG. 5 are diagrams for explaining the operation contents of this embodiment.

FIG. 3 is a diagram showing a state in which a frame 33 indicating the region is created in order to designate the movement target region 32 in the image data 31 displayed on the display device 3. In the example, it is drawn by operating the pointing device 7. This is obtained by specifying the upper left point and lower right point of the frame, and the data is expressed as vector data consisting of coordinate data of the upper left point and side length data.

FIG. 4 is a diagram showing a state in which the movement target area 32 is being moved. In this embodiment, in order to speed up the movement, the frame 41 for clearly indicating the movement target area 32 is This is not the aforementioned vector data, but image data represented by dots. In Figure 4,
Although the frame 41 is represented by a dot, it actually looks like a line, just like the frame represented by vector data (FIG. 3, 33).

FIG. 5 is a diagram showing the contents of the image data 31 after movement, and the frame 33 indicating the movement target area 32 is vector data as before movement. This is to convert the specified frame into vector data so that if any operation is to be performed after this movement operation, the specified frame can be processed.

Next, the operation of the above embodiment will be explained.

FIG. 6 is a flowchart showing the operation of the above embodiment.

First, in step S1, image data is read into a certain area in the RAM 23, the read image data is developed in the VRAM 24, and displayed on the display device 3. In addition,
The image to be read may be from the scanner 2 or from an external storage device.

Next, in step S2, the movement target area (
Create a frame to specify (Fig. 3 32) (Fig. 3 32)
3).

In step S3, the pointing device 7 (a mouse (registered trademark) is used in the above embodiment)
By continuing to press , it is assumed that the movement process has started.

When the movement process starts, first in step S4, the display image data within the movement target area specified in step S2 is copied to an area secured in the RAM 23. After the copying is completed, in step S5, the image data copied into the RAM in step S4 is converted into vector data dots, and a frame 41 represented by dots is drawn as shown in FIG. This framed image data will become moving image data from now on. Since the frame of this moving image data is also a dot, it can be displayed faster and in real time than a frame represented by vector data. In step S6, the display image data and image data (FIG. 3 33) within the movement target area (FIG. 3 32) specified in step S2 are cleared.

Next, in step S7, it is determined whether the pointing device has moved, and if the pointing device has moved, step S7
Proceed to 8. Otherwise, wait for the move to be performed.

Display image data to be moved in step S7 (
(Fig. 4 32) and a frame representing the movement target area (Fig. 4 41)
), the process continues in step S until it is confirmed in step Sll that the movement has been completed.
7 to step S11 are repeated.

First, when the start of movement is determined in step S7, since no data has been saved at the beginning, step S8
is not executed.

Next, in step S9, the pointing device 7
moves, and the display image data (Fig. 4, 32) and the image data currently displayed at the movement destination of the frame (Fig. 4, 41) are secured in the RAM 23 and stored in a certain area. Save. This is a moving image (Fig. 4, 32
．． 41) is a process for temporarily storing the displayed image that was at the destination of the moved image due to the movement of the moving image, and returning it to the original state after the moving image has been further moved. Moreover, all of these data are stored in the RAM 23.

In step S10, the moving image data in the RAM 23 created in step S5 is displayed at the moving destination.

In step Sll, it is determined whether the movement has ended, that is, whether the pressing of the pointing device 7 has ended, and if the pressing is still continuing, the process returns to step S7.

In step S7, it is determined that the pointing device 7 is moving, and the process proceeds to step s8.

In step S8, the display image data saved in the RAM 23 when the process in step s9 was previously performed is redisplayed at the original display position.

The same process is repeated from step S9 onwards.

If it is determined in step Sll that the moving process has ended, in step S12, the moving image is moved to the destination, that is, the position where the moving image was displayed in step S10.
The movement target area image data (FIG. 3 32) of the image (original image) read into the RAM 23 in step s1 is displayed. The reason for performing this step S12 is
This is because a frame is drawn around the moving image. The frame 41 created in step s5 described above has two sides (width (W)) of the vector data created in step S2.
) and height (H)) in the manner shown in FIG. 7, and is created within the image information area. Therefore, by the process 312, the inner frame disappears.

Next, in step 513, a frame represented by the aforementioned vector data is created around the area redisplayed in step S12 for the next movement process or other editing.

[Other Examples]

In the above embodiment, a frame is drawn around the moving image to speed up the movement, and the image is moved including the frame. However, in devices with fast processing speed, the moving image does not include the frame. It is also possible to erase the previous display frame each time the user moves and create a new frame at the destination. If this is done, the processes of step S5 and step S12 in the flowchart of the above embodiment become unnecessary.

Further, in the above embodiments, the region is shown as a rectangle, but it may be a circle, a polygon, or any other closed region.

〔Effect of the invention〕

As explained above, according to the present invention, a frame indicating the movement target image area is displayed together with the movement target image while the movement process is being executed, so that even if the movement target image and the surrounding images are similar, Even if the image area is moved, the image area to be moved can be clearly identified, and the image after the movement can also be clearly understood.

Furthermore, during execution of the movement process, the frame indicating the image area to be moved is used as dot data instead of vector data, making it possible to process quickly and display in real time.
