[0025]
【Example】
Hereinafter, an image processing apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a graphic processing apparatus according to an embodiment of the present invention.
[0026]
Referring to FIG. 1, the graphic processing apparatus includes an input unit 1, a region specifying unit 2, a graphic processing unit 3, a display unit 4, a region instruction memory 5, and a graphic memory 6. The input unit 1 includes a keyboard 1a and a pointing device 1b. The display unit 4 includes a display memory 4a and a display device 4b.
[0027]
The input unit 1 further includes a controller (not shown) that controls a keyboard 1a and a pointing device 1b serving as data and coordinate input devices. As the pointing device 1b, a pen type input device capable of directly inputting coordinates on the display screen of the display device 4b is used. FIG. 2 is a diagram showing an outline of the pen-type input device. The pen-type input device is provided with an execution confirmation switch SW1 for instructing execution of graphic processing. The user operates the operation confirmation switch SW1 with his / her finger while holding the pen-type input device. Confirmation can be made.
[0028]
The area designation unit 2 selects a predetermined designation method from a plurality of area designation methods according to the command input from the input unit 1, and designates an arbitrary area on the display screen by the selected designation method. Specifically, the area command unit 2 creates a specified area based on the data input from the input unit 1 in accordance with the selected designation method, and stores it in the area instruction memory 5. When the region designation is completed, the region designation unit 2 is informed to the graphic processing unit 3 that the region designation has been completed.
[0029]
When the area designating unit 2 informs that the area designation has been completed, the area processing unit 3 checks the area stored in the area instruction memory 5, and the graphic stored in the graphic memory 6 according to the stored area. Correct the information.
[0030]
The display unit 4 displays the graphic data stored in the graphic memory 6 and simultaneously displays the content stored in the area instruction memory 5. First, the graphic data is stored in the display memory 4a based on the data stored in the graphic memory 6, and the graphic data created from the information recorded in the area instruction memory 5 is overwritten in the display memory 4a. At this time, the graphic to be overwritten is, for example, a hatched pattern so that the graphic in the graphic memory 6 and the graphic in the area instruction memory 5 can be distinguished on the display device 4b. Here, although the figure of the area instruction memory 5 is hatched, it may be displayed in a different color to be distinguished, or may be expressed translucently. Moreover, you may enable it to visually recognize both figures by blinking the figure of the area | region instruction | indication memory 5 which has covered the figure of the figure memory 6. FIG. Furthermore, instead of displaying the designated area graphic in an overlapping manner, the result of executing the target graphic process may be displayed.
[0031]
Next, the graphic processing operation of the graphic processing apparatus configured as described above will be described. FIG. 3 is a flowchart for explaining the graphic processing operation of the graphic processing apparatus shown in FIG.
[0032]
First, in step S1, the data in the area instruction memory 5 is cleared. Next, in step S2, a graphic is displayed on the display screen of the display device 4b based on the data stored in the area instruction memory 5 and the graphic memory 6. Here, since the data in the area instruction memory 5 is cleared in step S1, the graphic based on the data in the area instruction memory 5 is not displayed.
[0033]
Next, in step S3, it is determined whether or not the tip of the pen-type input device that is the pointing device 1b is in contact with the display screen. If it is in contact, the process proceeds to step S4. If it is not in contact, step S3 is continued.
[0034]
Next, in step S4, it is determined whether or not the contact portion is within a graphic frame in which a graphic is displayed. If it is within the graphic frame, the process proceeds to step S5. If it is not within the graphic frame, the process proceeds to step S11.
[0035]
If it is within the graphic frame, in step S5, a designated area is created while the cursor on the display screen is moved by the pen-type input device.
[0036]
Next, in step S6, the data in the area instruction memory 5 is corrected based on the designated area created in step S5 according to the area designation mode designated in advance.
[0037]
Next, in step S7, the graphic data stored in the graphic memory 6 and the designated area stored in the area instruction memory 5 are superimposed and displayed on the display device 4b.
[0038]
Next, in step S8, it is confirmed whether or not the pen-type input device has left the display screen. If it is not separated, the process proceeds to step S5. If it is separated, the process proceeds to step S9.
[0039]
Next, in step S9, it is determined whether or not the execution check switch SW1 of the pen-type input device is pressed and execution of the graphic processing is confirmed. When the execution confirmation has not been performed, the process proceeds to step S3, and when confirmed, the process proceeds to step S10.
[0040]
Next, in step S10, the graphic data is corrected according to the set graphic processing mode. After the correction, the process proceeds to step S1 and the subsequent processing is continued.
[0041]
If it is determined in step S4 that it is not within the graphic frame, the menu / mode is changed in step S11. Next, in step S12, it is confirmed whether execution / decision is selected. If selected, the process proceeds to step S10. If not selected, the process proceeds to step S2.
[0042]
With the above processing, the predetermined graphic processing according to the graphic processing mode is performed only when the pen-type input device is separated from the display screen by a predetermined distance and the execution confirmation switch SW1 is pressed to confirm the execution. In this case, any area can be specified, changed, and modified using various area specifying methods provided in the area specifying unit 2, so that only a complicated figure can be specified easily. It becomes possible.
[0043]
Next, the display processing operation of the graphic processing apparatus will be described. FIG. 4 is a flowchart for explaining the display processing operation of the graphic processing apparatus shown in FIG.
[0044]
Referring to FIG. 4, first, display is stopped in step S21, and an area graphic is created from the contents of graphic memory 6 in step S22. Next, in step S23, an area graphic is drawn on the display memory 4b.
[0045]
Next, in step S24, an area graphic is created from the contents of the area instruction memory 5. Next, in step S25, the area graphic in the area instruction memory 5 is corrected to a hatched pattern. Next, in step S26, the area graphic corrected to the hatching pattern is overwritten on the display memory 4b. Next, the display is resumed in step S27.
[0046]
Through the above operation, the graphic stored in the image memory 5 and the area graphic stored in the area instruction memory are written into the display memory 4a and displayed on the display device 4b.
[0047]
Next, the area specifying operation of the image processing apparatus will be described more specifically. 5 to 7 are first to third diagrams for explaining an area designating operation of the graphic processing apparatus shown in FIG.
[0048]
First, with reference to FIG. 5, the case where the triangle TR located on the left side is designated will be described. In this case, as a region designation method, a circle centered on the coordinate position designated by the pen-type input device is displayed (step S5 in FIG. 3), and a circle movement locus formed according to the movement of the pen is used. The user traces the display screen from the point P1 through the point P2 to the point P3 with the tip of the pen-type input device, and the indication area IR shown in FIG. Here, conventionally, drawing or erasing is executed simultaneously with the movement of the pen-type input device. However, in this embodiment, the indication area is recorded in the area indication memory 5 and displayed on the display device 4b. Therefore, the user can specify an arbitrary shape using an arbitrary instruction method. After the designation of the area is completed, a predetermined graphic process is executed at a point P3 when the pen-type input device is released from the screen.
[0049]
Further, when an execution holding switch is newly provided in the pen-type input device, it is checked in step S9 shown in FIG. 3 whether or not the holding switch is off. If it is off, the process proceeds to step S10 and is not turned off. In this case, if the process proceeds to step S3, when the user is dissatisfied with the designated area, the user can release the pen while pressing the execution hold switch, and the area designation can be continued without moving to the graphic processing. It becomes possible. At this time, it is possible to select whether the area designated at the tip of the pen-type input device is the target area for graphic processing or not, in step S11 shown in FIG. The operation becomes easier. As described above, in this embodiment, an arbitrary area designation method can be selected from a plurality of area designation methods, and the area can be easily corrected after the designation. Can be performed. In this embodiment, in order to instruct suspension of graphic processing, an execution suspension switch is provided in the pen-type input device to keep it pressed. However, other methods may be used. For example, a method of operating a specific key on the keyboard instead of a pen-type input device, a method of holding a pen-type input device outside the graphic display frame and holding it off, a pen-type input such as a dielectric method There is a method in which the distance between the pen-type input device and the screen is detected using the device, and the process is not executed while the tip of the pen-type input device is not separated from the screen by a certain distance or more. Further, it may be possible to selectively set in advance whether to hold the pen or to execute the process when the pen is released.
[0050]
Next, the second area specifying operation of the graphic processing apparatus will be described. 8 to 10 are first to third diagrams for explaining the second region designation operation of the graphic processing apparatus shown in FIG.
[0051]
With reference to FIG. 8, a case where thick square SQ, triangle TR, circle CR, and rectangle LC are displayed on the graphic display frame FR on the display screen, and only the square SQ is to be moved will be described. . In addition, an area designation mode selection field M1 and an area change mode selection field M2 are displayed on the right side of the graphic frame FR. The area designation mode selection field M1 selects what area to create from the coordinates input by the pen-type input device, and the area change mode selection field M2 deals with the created area in the area instruction memory 6. Select whether to reflect. In the example shown in FIG. 8, as a region designation mode, a “rectangle” mode for creating a rectangle with two input points as diagonals, and a “circle” mode for designating a circle center point and one point on the circumference A "straight line" mode for drawing a straight line connecting two points and a "free curve" mode for tracing the pen point trajectory are prepared, and the area change mode is stored in the creation area and the creation instruction memory 6. An “addition” mode for taking the logical sum with the area, an “exclusion” mode for subtracting the area of the logical product of the two areas from the area instruction memory 6 and an “inversion” mode for taking the exclusive logic of the two areas are prepared. Yes.
[0052]
The user can select an arbitrary designation method from the area designation mode selection field M1 and the area change mode selection field M2 on the right side. Referring to FIG. 9, “rectangular” and “inverted” modes are currently selected. In FIG. 9, the selection state is indicated by a thick frame. In this state, if the tip of the pen-type input device is lowered to a point P1 on the screen, and then slid to the point P2 as it is to release the pen-type input device from the screen, a rectangle R1 indicated by a dotted line can be created (step of FIG. S5). The area designating unit 2 compares the data of the rectangle R1 and the area designating memory 5, inverts the designated rectangular part from the non-selected area to the selected area, and stores it in the area instruction memory 5 (FIG. 3). Step S6). The display unit 4 displays the selected area superimposed on the contents of the graphic memory 6 by a method such as hatching, lighting, or translucent (step S7 in FIG. 3).
[0053]
Similarly, when the pen point input device is traced from the point P3 to the point P4 and the rectangle R2 indicated by the broken line is designated, the area designating unit 2 takes exclusive logic between the contents of the area designation memory 5 and the rectangle R2. The result is stored in the area instruction memory 5. In this case, the rectangle R2 formed by the points P3 and P4 is inverted from the selected region to the non-selected region, and the triangle TR is out of the selected region.
[0054]
Next, as shown in FIG. 10, “free curve” and “delete” modes are selected from the area designation mode selection field M1 and the area change mode selection field M2, and in this state, the periphery of the rectangle LC is selected with a pen-type input device. In other words, the area created by the trajectory of the pen-type input device becomes a non-selected area, and the rectangle LC can be excluded from the movement target. Similarly, when the “add” mode is selected from the area change mode selection field M2, the shortage at the left end of the quadrangle SQ can be additionally corrected. Therefore, if the above operation is repeated, even a delicate figure such as the square SQ and the circle CR can be easily separated and corrected.
[0055]
When the region correction is repeated by the operation as described above and a user's satisfactory region can be designated, the user touches the decision panel at the lower left of the screen with the pen-type input device (or the execution key provided in the keyboard 1a). push). As a result, when the graphic processing unit 3 starts the process of moving the designated area and designates the movement amount with the pen-type input device, the contents of the graphic memory 6 are corrected (step S10 in FIG. 3).
[0056]
With the above operation, the designated area can be easily corrected before graphic processing (for example, movement processing), so that the user does not have to worry about small mistakes, and the burden on the user can be greatly reduced. . In the above embodiment, the pen-type input device is used as the input device, but other input devices such as a mouse and a key may be used.
[0057]
Next, a graphic processing apparatus according to another embodiment of the present invention will be described with reference to the drawings. FIG. 11 is a block diagram showing a configuration of a graphic processing apparatus according to another embodiment of the present invention.
[0058]
Referring to FIG. 11, the graphic processing apparatus includes an input unit 1, a nearest point search unit 7, a coordinate position input determination unit 8, a point sequence data memory 9, a created point sequence memory 10, and a display unit 41. The input unit 1 includes a keyboard 1a and a pointing device 1b. The display unit 41 includes a display memory 4a, a display device 4b, and an approximate curve creation unit 4c.
[0059]
In this embodiment, a case where a spline curve is created from input point sequence data will be described. The same parts in the graphic processing apparatus shown in FIG. 11 and the graphic processing apparatus shown in FIG. The basic configuration of both graphic processing apparatuses is substantially the same.
[0060]
The created point sequence data is stored in the point sequence data memory 9, and the data to be corrected or newly created point sequence data is temporarily recorded in the created point sequence memory 10 and processed. In addition, in terms of processing characteristics, it includes a nearest point search unit 7 that searches for point data closest to a designated area, and an approximate curve creation unit 4c that creates curve data from point sequence data. In addition, a coordinate position input determination unit 8 that determines the input of the coordinate position input from the coordinate unit is provided.
[0061]
Next, the graphic processing operation of the graphic processing apparatus configured as described above will be described. FIG. 12 is a flowchart for explaining the graphic processing operation of the graphic processing apparatus shown in FIG.
[0062]
Referring to FIG. 12, first, when coordinates are input in step S31, it is determined in step S32 whether or not the input coordinates are within the graphic frame. If it is within the graphic frame, the process proceeds to step S33, and if not, the process proceeds to step S51.
[0063]
If it is within the graphic frame, it is determined in step S33 whether or not it is in the cathode movement mode. If it is the cathode movement mode, the process proceeds to step S34, and otherwise, the process proceeds to step S40.
[0064]
In the case of the cathode movement mode, in the step S34, a neighborhood point of the input coordinates is searched. Next, in step S35, the cathode is displayed on the screen. Next, in step S36, the movement of the tip of the pen-type input device is detected. Next, in step S37, it is confirmed whether or not the tip of the pen-type input device has left the display screen. If it has left, the process proceeds to step S38, and if not, the process proceeds to step S34.
[0065]
If the pen-type input device has left the display screen, the cursor point is determined in step S38. Next, in step S39, the cursor movement mode is canceled, and the process returns to step S31 and the subsequent processing is continued.
[0066]
If it is determined in step S33 that the mode is not the cursor movement mode, the mode is checked in step S40. If it is the correction mode, the process proceeds to step S41, if it is the new point mode, the process proceeds to step S46, and if it is the deletion mode, the process proceeds to step S47.
[0067]
If it is the correction mode, the nearest point of the input coordinates is searched in step S41. Next, in step S42, the movement of the tip of the pen-type input device is detected. Next, in step S43, it is confirmed whether or not the tip of the pen-type input device has left the display screen. If it is separated, the process proceeds to step S49, and if it is not separated, the process proceeds to step S44.
[0068]
If not, the created point sequence data is corrected in step S44. Next, in step S45, the curve is calculated and displayed, and the process proceeds to step S42.
[0069]
If it is determined in step S43 that the pen-type input device has been separated, the created point sequence data is corrected in step S49. Next, in step S50, the curve is calculated and displayed, the process proceeds to step S31, and the subsequent processing is continued.
[0070]
If it is determined in step S40 that the mode is the new point mode, the generated point sequence data is recreated in step S46, the process proceeds to step S42, and the subsequent processing is continued.
[0071]
If it is determined in step S40 that the mode is the deletion mode, the nearest point of the input coordinates is searched in step S47. Next, the point sequence data created in step S48 is recreated, the process proceeds to step S49, and the subsequent processing is continued.
[0072]
Next, the operation of creating a free curve according to the above flowchart will be described more specifically. 13 to 15 are first to third diagrams for explaining a free curve creation operation of the graphic processing apparatus shown in FIG.
[0073]
Now, assume that a screen as shown in FIG. 13 is displayed on the display device 4b. In FIG. 13, the user has input in the coordinate order from the point P1 to the point P5, and a curve passing through these five points is displayed in the graphic frame of the screen. A cursor CS representing the direction is displayed at the last input point P5. The direction of the cursor means on which side the next point is created.
[0074]
In addition, panels M1 to M4 for selecting four types of input modes are displayed on the right side of the graphic frame. Here, the “position correction” mode is a mode for changing the already input point coordinates, the “new point” mode is a mode for adding a new point, and the “point deletion” mode is already input. This is a mode for deleting a point, and the “cursor movement” mode is a mode for moving the cursor CR at the current point P5 to another point, for example. In the initial state, the “new point” mode is selected, and when the user inputs the points P1 to P5 in this state, a new point sequence is created and recorded in the created point sequence memory 10. Further, since this data is undetermined data, it is not recorded in the point sequence data memory 9.

In the above state, if the user points somewhere in the graphic frame (step S31 in FIG. 12), the point sequence data is changed to 6 as shown in FIG. 14 (step S46 in FIG. 12). ), You can create a continuation of the curve. Here, when the position correction panel M1 is touched to enter the “position correction” mode (step S51 in FIG. 12) and then the pen-type input device is contacted in the vicinity of P2, the nearest point search unit 7 is the closest point. If P2 is searched (step S41 in FIG. 12) and the pen-type input device is dragged, the coordinates of the point P2 in the point sequence data in the created point sequence memory 10 are corrected, and the curve is corrected as indicated by the dotted line. be able to.
[0076]
Further, when the cursor movement panel M4 is touched, the cursor movement mode is entered, and the cursor CS at the point P5 can be moved to another point (steps S34 to S39 in FIG. 12). For example, when a point near the point P2 is designated, the cursor CS moves the cursor CS to the point P2, which is the nearest point, and displays the cursor beside the point P2 (step S38 in FIG. 12). Next, as shown in FIG. 15, when points P7 and P8 are input as new points, these points are inserted between the positions next to the point where the cursor CS is located, that is, between the points P2 and P3. (Step S46 in FIG. 12). In this case, the cursor CS is moved in order of the point P7 and the point P8. Moreover, if the direction reversal panel M5 is touched once and the direction of the cursor CS is reversed, it can be inserted between the point P2 and the point P1.
[0077]
After making any corrections as described above, if the cathode is returned to the point P5 (or point P6), it is also possible to input the continuation of the curve. In the above example, a new input point sequence has been described. However, the present invention can be similarly applied to correction of a key input point sequence. Further, although several panels are prepared on the right side on the display screen, these panels may be read with a pen gesture, for example, by moving the cursor so as to surround an existing point. The above coordinate inputs are all free coordinates. However, for example, a plurality of other designation methods such as intersections of two straight lines, contact points, or center points may be prepared.
