Abstract

PURPOSE:To improve operability, by issuing picture element shape change indication by a pointing device at a position where a picture element is written, and changing the size or the shape of the picture element to be written. CONSTITUTION:When the size of the picture element written by an operator is changed, a cursor moving with a mouse that is a pointing device is displayed on a picture plane on which the picture element is written, and another mouse button other than the button to write the picture element is depressed. In other words, by displaying the cursor on a part where a bit of picture information is displayed by the operator, and depressing the button of the mouse 2-4 to write the picture element, it is possible to input the picture element bas-on the size of the cursor. In such a way, since the cursor changed to the size of a changed picture element is displayed, the size of the changed picture element can be confirmed by the operator.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is suitable for an image processing device equipped with an input device such as a mouse that specifies an arbitrary position on an image and input information is specified by the input position. This invention relates to a pixel input method.

[Conventional technology]

Conventional devices (1) when selecting the pixel size to write, temporarily erase the displayed image from the screen, display the pixel size that can be selected on the screen, and then In some cases, a cursor is set to be moved by a pointing device and the pixel size is selected by pressing a button on the pointing device, or (2) selectable pixel sizes are displayed at a specific position on the screen and The pixel size was selected by setting a cursor and pressing a button on the pointing device.

[Problem that the invention seeks to solve]

However, in the above-mentioned conventional technology (1), it is not possible to confirm the size of the pixel to be written on the image to be written, and in (2), the pattern indicating the size of the pixel to be written on the image cannot be confirmed. Since the image is displayed on the screen, the area where the image is displayed is narrowed down.

The purpose of the present invention is to eliminate the inconvenience of having to change the display screen every time you try to change the size of a pixel to be written, and having to select the pixel size and then check again at the position of the pixel to be written. There is a particular thing.

[Means for solving problems]

The purpose of the above is to display a cursor that can be moved using a mouse, which is a pointing device, on the screen where the operator is writing the pixel when changing the size of the pixel to be written, and to use a mouse button that is different from the mouse button for writing one pixel. This is achieved by changing the size of the pixels written by pressing the mouse button.

[Effect]

If the operator displays a cursor in the area where image information is displayed and presses the mouse button to write a pixel, the pixel can be input according to the size of the cursor, then the position to write the pixel The operator can confirm the changed pixel size by pressing the mouse button to change the pixel size and displaying a cursor that has changed to the changed pixel size. Therefore, by pressing the mouse button at the position where a pixel is to be written, the size of the pixel to be written can be selected.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a flow diagram of pixel writing processing. FIG. 2 is a block diagram of an embodiment of an image processing device according to the present invention;
FIG. 3 is a diagram of an image display screen according to the present invention. 1 image scanner 2-2 or external storage device 2-7 in FIG.
The image data input from the central processing unit 2-1 is stored in the image information storage memory 2-6 (1-1) and displayed on the display device 2-3 as the screen shown in FIG. 3 (1-2). ,
The operator edits the image by operating the mouse 2-4 while looking at the display screen of the display device 2-3 (1-5).

Here, mouse 2-4 has a "pixel write button"
Assume that two buttons, ``pixel size change buttons,'' are provided.

FIG. 4 is a flow diagram of a process for changing the size of pixels to be written, indicated by 1-8, as the mouse cursor changes from (a) to (b) in FIG. If you want to change the size of pixels to be written when the size of the mouse cursor 3-2 is the same, press the "pixel size change button" on the mouse 2-4 (4-1). ! 2-
1 receives a button press signal and writes information specifying a pixel one step larger than the currently displayed pixel of the size of the mouse to the pixel information storage memory 2-5 (4-3)
, Mouse cursor 3 with a size according to the specified pixel information
-3 on the display device 2-3 (4-5). If the maximum pixel size specified in the pixel information storage memory 2-5 is set, display the "pixel When you press "Resize button", pixel information storage memory 2-5
The pixel specified in is the smallest pixel (4-6
).

Then, when the "rli-a size change button" is pressed again, the 1-pixel information is changed as described above.

Figure 5 shows the flow of pixel writing processing for 1 display device!
When the operator writes pixels to the image ↓2 displayed in 2-3, by moving this mouse 2-4, the image ↓2 is displayed on the 1 display screen 3-1 as shown in Figure 3. Move the mouse cursor 3-2 located at the position where the operator wants to write the pixel, and
By pressing the "Image writing button" (5-1)
, a pixel writing coordinate value is given to the central processing unit fi 2-1 (5-2), and the central processing unit 2-1 stores pixel information of the pixel according to the size of the mouse indicated by the mouse cursor 3-2. The pixel selected from the memory 2-5 and selected at the given coordinate value is written into the image information storage memory 2-6 (5-3), and the pixel at the written position is displayed (5-4). ).

Figure 6 shows the internal structure of the pixel information storage memory 2-5.
The pixel information is stored in the pixel information storage memory 6-1 as designated pixel numbers 6-299, pixel location information 6-3, and pixel information 6 for each pixel.
-4.

The specified pixel number 6-2 indicates the sequence number of the specified pixel position information. The 0 pixel position information indicates the position where the pixel information 6-4 is stored in the pixel information storage memory 6-1. Assuming that the pixel information 6-4 is sorted in ascending order according to the size of the pixel information, each pixel information size 6-4-1. Pixel information coordinates of specified point specified by cursor 6-4-2
．． It is composed of pixel data 6-4-3. As shown in FIG. 7, each of these data is the pixel data 6-4.
-3 is expressed as the size in the vertical and horizontal directions and data for each point.

If the operator presses the "pixel size change button" when 1 pixel information In is specified here, the central processing unit 2-1 changes the specified pixel number to In+1.
If In is the maximum size, write the specified pixel number to the minimum size Io.
Then, the size of the mouse cursor is read out from the pixel information storage memory 2-5 from the pixel information storage memory 2-5, and the size of the mouse cursor is set to the pixel information position 6-2. Then, the actual pixel information 6-4 is read out and a cursor indicating the size of the pixel data is displayed.

Each time the operator presses the "pixel size change button," the specified pixel data is updated as described above, so press the "pixel size change button" until the cursor shape of the desired pixel size appears. I can do it.

When the "pixel write button" is pressed by the operator, the coordinates specified by the mouse are aligned with the pixel information specified point coordinates 6-4-2, and the pixel data 6-4-3 of the specified pixel number 6-2 is written. is written into the image storage memory 2-6, and the written image is displayed on the display device 2-3.

〔Effect of the invention〕

According to the present invention, since the size of the pixel can be selected when writing the pixel into the image, there is an advantage that the operator can confirm and write the pixel required for the image.
