DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus for designating a processing range for an image and performing a trimming process, a predetermined image processing, or the like on the specified processing range.

[0002]

2. Description of the Related Art When performing various processes such as a processing process and a correction process on an image, it is often desired to perform the process on only a part of the image instead of the entire image. And in such a case,
Conventionally, an area to be processed in an image (hereinafter, referred to as
The image processing is performed only on the specified processing range.

FIG. 7 is a diagram for explaining a conventional processing range designation. On the display 2, a processing target image 17 and a mouse cursor 19 are displayed. When the operator gives an instruction from the mouse, a part of the processing target image 17 is designated as a processing range 18 (an area surrounded by a dotted line in the drawing). The processing range 18 is a rectangular area as shown in the figure. When the operator specifies the processing range 18, the operator specifies the diagonal of the rectangle. Here, first, the mouse cursor 19
Is moved to the position of the upper left corner of the processing range 18 in the figure, and after specifying the corner, the mouse cursor 19 is moved to the position of the lower right corner, and the relevant corner is specified (the state of FIG. 7). , The processing range 18 is determined.

When the processing range 18 is determined, the operator may appropriately determine the size or the like based on the pattern of the image 17 to be processed.
In some cases, it is desired to determine the position and size of 8 accurately. For example, when the processing target image 17 is superimposed on another image, the position and size of the processing range 18 need to be set numerically and accurately. In such a case, the numerical information is displayed in the information area 20 at the lower end of the display 2 so that the operator can grasp the numerical information on the display position of the mouse cursor 19 and the size of the processing range 18. That is, in FIG. 7, the relative coordinate values “X: 820, Y: 6” on the image at the display position of the mouse cursor 19 are displayed.
20 ", the density value at that position" R: 15, G: 50,
B: 20 ”and the size“ W:
"300, H300" are displayed in the information area 20. In the above description, the relative coordinate values are XY coordinate values on the image displayed on the display 2,
The density value is a gradation value in each of the RGB planes, and the size is a width (W) and a height (H) of the processing range 18 in the display area of the display 2.

As described above, since the necessary numerical information is displayed in the information area 20 on the display 2, the operator can check the numerical information and accurately process the first processing range.
8 can be specified.

[0006]

However, when the information area 20 is displayed at the lower end of the display 2 as shown in FIG.
The viewpoint must be largely moved between the information area 20 and the information area 20, and the burden is large. In particular, when the processing range 18 is repeatedly designated, the burden on the operator is significantly increased, and the work efficiency is reduced.

As a means for solving such a problem, a method of displaying an information area as shown in FIG. 8 has been proposed. In FIG. 8, an information area 21 indicating the same numerical information as above is displayed at a desired position on the display 2 designated by the operator. In this case, if the distance between the mouse cursor 19 and the information area 21 is short, it is not necessary to move the viewpoint so much. However, if the distance is large, the viewpoint must be moved too. Especially,
If the size of the processing range 18 is large, the interval between the mouse cursor 19 and the information area 21 always becomes large, which still imposes a burden on the operator.

In view of the above problems, an object of the present invention is to provide an image processing apparatus capable of reducing the burden of moving an operator's viewpoint when designating a processing range for an image and improving work efficiency.

Then, the control means 3 stores the image signal provided from the image input device 1 in the memory 4 and displays the image signal on the display 2 as an image. The display 2 not only displays an image, but also displays a mouse cursor (position designation identifier) 19 described later and necessary numerical information. The memory 4 stores an operation program of the image processing apparatus and various numerical information data in addition to the image signal data.

The control means 3 includes a mouse 5 and a keyboard 6
And are connected. The mouse 5 is used to graphically input the position of the mouse cursor 19 displayed on the display 2 and to graphically specify and input the positions of the two points of the mouse cursor 19 to display an arbitrary area on the image displayed on the display 2. Can be designated as a trimming range (processing range). Specifically, when the operator moves the mouse 5 two-dimensionally, the cursor display control means 7 described later moves the mouse cursor 19 in accordance with the movement. Move on the display 2. Then, the operator operates the mouse button 5 provided on the mouse 5.
By pressing and releasing “a”, an arbitrary area on the image can be designated as a trimming range. The keyboard 6 is a device for inputting various commands to the control means 3 and is also a device for giving an auxiliary instruction on the position input of the mouse cursor 19 and the designation of the trimming range.

The control means 3 has a cursor display control means (identifier display control means) 7 and an information area display control means (information area display control means) 8. The cursor display control means 7 has a function of graphically displaying a mouse cursor 19 and a specified trimming range on the display 2 based on an input from the mouse 5 or the keyboard 6. The information area display control means 8 determines the display position of the mouse cursor 19 and the display position of the information area indicating the numerical information on the size of the trimming range, and controls the information area to be displayed at the position on the display 2. However, this will be described later in detail.

Next, the operation of the image processing apparatus having the above configuration will be described. As described above, first, the image input device 1 optically reads a document, and supplies the read information to the control unit 3 as an image signal. And control means 3
Stores the received image signal in the memory 4 and displays the image signal as an image 17 on the display 2. FIG. 2 is a diagram illustrating a state where the image 17 is displayed on the display 2.

As shown in FIG. 2, when displaying an image, the cursor display control means 7 displays the mouse cursor 1 on the display 2.
9 and the information area display control means 8
Displays the information area 30. The information area 30 shows numerical information on the display position of the mouse cursor 19 at that time, that is, the relative coordinate value of the display position of the mouse cursor 19 on the image and the density value at that position. The information area display control means 8 displays the information area 30 near the lower part of the mouse cursor 19. When the operator moves the mouse 5 to move the mouse cursor 19 on the display 2, the information area 30 follows. The information area 30 is also controlled to move. At this time, the numerical information indicated in the information area 30 is sequentially changed as the display position of the mouse cursor 19 is moved.

Next, when performing some kind of image processing on a part of the image 17, the operator designates the part as a trimming range and performs a desired process on the trimming range. In the image processing apparatus considered in this example, the trimming range is specified as a rectangular area, and specifically, the diagonal of the rectangle (the upper left corner and the lower right corner or the upper right corner and the lower left corner of the rectangle) ) To specify the trimming range. Less than,
The case where the upper left corner of the rectangle is specified as the trimming range and then the lower right corner is specified will be described.

First, the operator operates the mouse 5 and
The mouse cursor 19 is moved to the position of the upper left corner of the rectangle to be designated as the trimming range 18. In this case, the mouse 5 may be operated so that the position of the mouse cursor 19 is at a desired position while confirming the numerical information indicated in the information area 30. Then, by pressing the mouse button 5a of the mouse 5, the corner of the trimming range 18 is designated. FIG. 3 is a diagram showing a state where the upper left corner of the trimming range 18 is designated. As shown in the drawing, when the mouse button 5a is pressed, the information area display control means 8 causes the information area (information area) 31 indicating numerical information on the display position of the mouse cursor 19 and the size of the trimming range 18 at that time. indicate. At this time, the information area 31 is displayed near the position of the mouse cursor 19 at that time.

Here, "near" is a term meaning that the distance between the end of the information area 31 and the end of the mouse cursor 19 is within 30 pixels.

In FIG. 3, the trimming range 1
Since one corner of 8 is designated, “W: 0, H: 0” is displayed in the information area 31 as its size. When the mouse button 5a is pressed, the cursor display control means 7 displays the trimming range 18, but at the time of FIG.
Is not shown in the figure because it is a point.

Next, the operator moves the mouse 5 while holding down the mouse button 5a, and moves the mouse cursor 19 to a position near the lower right corner of the rectangle to be designated as the trimming range 18. At this time, the cursor display control means 7 displays a rectangular trimming range 18 with the corner designated above and the display position of the mouse cursor 19 as diagonals. Information area display control means 8;
The information area 3 follows the movement of the mouse cursor 19.
1 is also controlled to move. Then, with the movement of the display position of the mouse cursor 19, the display position indicated in the information area 31 and the numerical information on the size of the trimming range 18 are also sequentially changed.

Here, "moving following" means moving the information area 31 so that the end of the information area 31 and the end of the mouse cursor 19 always have the same interval.

The operator checks the numerical information in the information area 31, that is, the numerical information on the display position of the mouse cursor 19 and the size of the trimming range 18, and checks the lower right corner of the rectangle in which the mouse cursor 19 is to be designated as the trimming range 18. After the mouse button 5a is released, the trimming range 18
Is specified.

FIG. 4 is a diagram showing how the lower right corner of the trimming range 18 is designated. This figure shows a state immediately before the operator releases the mouse button 5a, and shows a state where the mouse cursor 19 has reached the position of the lower right corner of the trimming range 18. As shown, a trimming range 18 having a size of “W: 300, H: 400” is designated here.

After the trimming range 18 is specified as described above, predetermined image processing is performed on the area specified by the trimming range 18.

In this manner, the trimming range 18
Is designated, the information area 31 is displayed near the mouse cursor 19, so that it is possible to reduce the burden of moving the viewpoint of the operator when accurately specifying the processing range 18 while confirming the numerical information. , Work efficiency can be improved.

When the trimming area 18 is designated, the information area 31 is moved following the movement of the mouse cursor 19, so that the information area 31 is always kept near the mouse cursor 19 regardless of the size of the trimming area 18. The area 31 is displayed, and the burden on the operator to move the viewpoint can be reduced.

In the above description, the trimming range 1
