Description

  The present invention relates to an image processing apparatus for setting a part of an image as a processing target range.

  A part of the image displayed on the display unit such as a liquid crystal display device is arbitrarily set as the processing target range, and the image that is the processing target range is enlarged and displayed, or the image that is the processing target range is displayed. Conventionally, specific image processing has been performed.

  A general method for setting a part of an image as a processing target range is to draw a rectangular or circular figure on the image displayed on the display unit via a mouse and a computer, and be surrounded by these figures. A technique for setting an area as a processing target range is known.

  In such a method, in the case of a rectangle, for example, one reference coordinate point in an image is designated by a mouse click operation or the like, and the reference coordinate point is dragged (moved) from the reference coordinate point. A rectangle whose diagonal is a line connecting the point and the coordinate point of the drag destination is drawn. The size of the rectangle can be adjusted in accordance with the drag operation, whereby the user can adjust the processing target range to a desired size. Usually, such a rectangle is composed of two sides along the horizontal direction and two sides along the vertical direction. Therefore, it is not appropriate when it is desired to set an obliquely extending region as the processing target range.

  On the other hand, in the case of a circle, for example, two coordinate points in the image are designated by clicking the mouse, etc., and a circle passing through the two coordinate points and having a diameter between the two coordinate points is drawn. . By adjusting the distance (diameter) between the two coordinate points, the user can adjust the processing target range to a desired size.

  Patent Document 1 discloses that a circular cursor having a predetermined diameter displayed on an image is moved, and an area surrounded by the entire movement locus is set as a processing target range. Further, in Patent Document 2, when two coordinate points are specified in an image, a rectangle extending by a predetermined width in both directions orthogonal to the line segment is drawn with reference to a line segment connecting the two coordinate points. It is disclosed that a region surrounded by is set as a processing target range.

  The techniques of Patent Literature 1 and Patent Literature 2 are also effective when it is desired to set a diagonally extending region as a processing target range.

  However, in the technique of Patent Document 1, the diameter of the circular cursor is the width dimension of the graphic that can be drawn. For this reason, in order to change the width dimension, it is necessary to perform a setting change operation for changing the setting value of the diameter of the circular cursor. This is troublesome.

  In the technique of Patent Document 2, a predetermined width that extends in both directions orthogonal to a reference line segment is a width dimension of a drawable figure. For this reason, in order to change the predetermined width, it is necessary to perform a setting change operation for changing the set value of the predetermined width. This is troublesome as in Patent Document 1.

  The present invention has been made in view of such circumstances, and provides an image processing apparatus capable of easily and efficiently setting a desired processing target range in an image displayed on a display unit more flexibly. The purpose is to do.

  The present invention passes through a display unit for displaying an image, a coordinate designating unit for designating two coordinate points for the image displayed on the display unit, and two coordinate points designated by the coordinate designating unit. A circle having a diameter of the distance between the two coordinate points is superimposed on the image and drawn with a basic line having a predetermined line width, and the circular basic line drawn by the circular drawing unit An image processing comprising: a processing range setting unit that increases a line width, defines an annular region, and sets a region surrounded by an outline of the annular region as a processing target range Device.

  According to the present invention, for example, when it is desired to set the outer edge portion of the circular region or the periphery thereof as the processing target range, a circle that roughly overlaps the outer edge portion is drawn by the circular drawing portion, and drawn by the circular drawing portion. The processing range can be set as an annular region having a desired width by arbitrarily increasing the line width of the circular base line that has been set by the processing range setting unit. For this reason, the processing target range can be set more flexibly as an annular region having a desired width in the image displayed on the display unit easily and efficiently.

  The present invention also includes a display unit that displays an image, a coordinate designating unit that designates three coordinate points for the image displayed on the display unit, and three coordinate points designated by the coordinate designating unit. An arc drawing unit that draws an arc passing through the image with a basic line having a predetermined line width, and increases the line width of the basic line of the arc drawn by the arc drawing unit, thereby creating a fan-shaped region. An image processing apparatus comprising: a processing range setting unit that defines and sets a region surrounded by the contour of the fan-shaped region as a processing target range.

  According to the present invention, for example, when it is desired to set an arcuate part or its periphery as a processing target range, an arc that roughly overlaps the arcuate part is drawn by the arc drawing unit, and is drawn by the arc drawing unit. By arbitrarily increasing the line width of the basic line of the arc by the processing range setting unit, the processing target range can be set as a fan-shaped region having a desired width. For this reason, the processing target range can be set more flexibly as a fan-shaped region having a desired width in the image displayed on the display unit easily and efficiently.

Moreover, it is preferable that the processing range setting unit increases the line width of the basic line by an equal distance in the inner diameter direction and the outer diameter direction.
In this case, it is only necessary to draw a circle or arc having an intermediate diameter between the inner diameter and the outer diameter of the annular or fan-shaped region to be set as the processing target range by the circular drawing unit or the arc drawing unit. Setting operation can be performed easily.

  Further, the present invention provides a display unit for displaying an image, a coordinate designating unit for designating two coordinate points for the image displayed on the display unit, and between the two coordinate points designated by the coordinate designating unit. The line segment connecting the line segment is drawn on the image with a basic line having a predetermined line width, and the line width of the basic line drawn by the line segment drawing unit is increased. An image processing apparatus comprising: a processing range setting unit that defines a rectangular region and sets a region surrounded by an outline of the rectangular region as a processing target range.

  According to the present invention, for example, when it is desired to set an obliquely extending line segment part or its periphery as a processing target range, a line segment roughly overlapping the obliquely extending line segment part is drawn by the line segment drawing unit. By arbitrarily increasing the line width of the basic line drawn by the line drawing unit by the processing range setting unit, the processing target range is defined as a rectangular region extending obliquely and having a desired width. Can be set. For this reason, the processing target range can be set more flexibly as a rectangular region having a desired width in the image displayed on the display unit easily and efficiently.

The processing range setting unit preferably increases the line width of the basic line by equal distances in both directions orthogonal to the line segment.
In this case, the line segment that overlaps the center line of the rectangular region that is desired to be set as the processing target range may be drawn by the line segment drawing unit, so that the processing target range setting operation can be easily performed.

  The coordinate designating unit preferably includes a mouse. In this case, it is preferable that the processing range setting unit increases the line width according to the rotation of the mouse wheel. In this case, the setting operation of the processing target range can be easily performed.

  In addition, the area set as the processing target range by the processing range setting unit is generally displayed on the display unit.

According to the present invention, for example, when it is desired to set the outer edge portion of the circular region or the periphery thereof as the processing target range, a circle that roughly overlaps the outer edge portion is drawn by the circular drawing portion, and drawn by the circular drawing portion. The processing range can be set as an annular region having a desired width by arbitrarily increasing the line width of the circular base line that has been set by the processing range setting unit. For this reason, the processing target range can be set more flexibly as an annular region having a desired width in the image displayed on the display unit easily and efficiently.
Further, according to the present invention, for example, when it is desired to set an arc-shaped portion or its periphery as a processing target range, an arc that roughly overlaps the arc-shaped portion is drawn by the arc drawing portion, and drawn by the arc drawing portion. The processing target range can be set as a fan-shaped region having a desired width by arbitrarily increasing the line width of the basic line of the arc formed by the processing range setting unit. For this reason, the processing target range can be set more flexibly as a fan-shaped region having a desired width in the image displayed on the display unit easily and efficiently.
Further, according to the present invention, for example, when it is desired to set an obliquely extending line segment part or its periphery as a processing target range, a line segment roughly overlapping the obliquely extending line segment part is formed by the line segment drawing unit. The processing target is processed as a rectangular area extending diagonally and having a desired width by arbitrarily increasing the line width of the basic line drawn by the line drawing unit by the processing range setting unit. A range can be set. For this reason, the processing target range can be set more flexibly as a rectangular region having a desired width in the image displayed on the display unit easily and efficiently.

It has become.

  The graphic drawing unit 14 superimposes a circular, arc, or straight line segment on the image of the workpiece 121 displayed on the display unit 20 in accordance with the operation of the mouse 30 by the user, and a basic line having a predetermined line width. It is designed to be drawn with. Further, the processing range setting unit 15 increases the line width of a basic line of a circle, an arc, or a line segment drawn by the figure drawing unit 14 in accordance with the operation of the mouse 30 by the user. Then, the processing range setting unit 15 selects a figure (annular, fan-shaped or rectangular figure) in which the line width of the basic line of the circle, arc, or line segment is increased in accordance with the operation of the mouse 30 by the user. A region surrounded by the contour is set as a processing target range.

It is possible to set a region surrounded by the outline as a processing target range.

  Then, the image processing apparatus 1 according to the present embodiment enlarges and displays the image set as the processing target range, or parameters related to the shape in the image set as the processing target range (circle diameter, arc radius). , Side length, etc.) can be calculated with high accuracy.

  Further, in the present embodiment, setting of the processing target range by the annular region, setting of the processing target range by the fan-shaped region, and setting of the processing target range by the rectangular shape are performed by the user's selection. It has become. Specifically, the graphic drawing unit 14 draws one of a circle, an arc, or a line segment, and the processing range setting unit 15 can set the processing target range based on one of these ( That is, the graphic drawing unit 14 functions as a circular drawing unit, an arc drawing unit, or a line segment drawing unit in claims.

  Next, the operation of the image processing apparatus 1 having the above configuration will be described.

  FIG. 3 shows an example of an image of the workpiece 121 displayed on the display unit 20. In the example of FIG. 3, the entire planar image of the upper surface of the workpiece 121 is displayed in the display area A1. Specifically, in the upper surface region of the workpiece 121 after being processed by the tool 122, a columnar part F1, a curved wall part F2 having an arc-shaped edge (arc-shaped part), and a rectangle extending obliquely long. A wall F3 is shown.

  In the following, an example in which the outer edge portion of the cylindrical portion F1 or its periphery is set as a processing target range by an annular region, and the arc-shaped edge (arc-shaped portion) of the curved wall portion F2 or its periphery is fan-shaped. An example of setting as a processing target range by area and an example of setting a line segment part (side) or its periphery of the rectangular wall portion F3 as a processing target range by a rectangular area extending obliquely will be described.

(Setting of processing target range by annular area)
First, an example in which the user sets the outer edge portion of the cylindrical portion F1 shown in FIG. 3 or its periphery as a processing target range by an annular region will be described with reference to FIG.

  FIG. 4A shows an enlarged view of the columnar portion F1 shown in FIG. When setting the outer edge part or its periphery of the cylindrical part F1 as a processing target range by an annular area, the user operates the mouse 30 to cause the figure drawing part 14 to draw a circle.

  In this case, first, the user operates the mouse 30 to designate one coordinate point P1. In the present embodiment, as shown in FIG. 4B, the user positions the cursor at a point located on the outer edge of the columnar portion F1, and clicks (presses, so-called mouse down) the first operation portion 31. As a result, the coordinate point P1 is designated.

  Next, the user drags (moves) the mouse 30. In the present embodiment, as indicated by the arrow in FIG. 4C, the user moves the cursor along the diameter direction of the cylindrical portion F1 while maintaining the state where the first operation unit 31 is pressed. The mouse 30 is dragged.

  Then, the user designates the coordinate point P2 at the drag destination. In the present embodiment, as shown in FIG. 4D, the user is a point located on the outer edge of the columnar part F1, and the point facing the coordinate point P1 across the center of the columnar part F1. The coordinate point P2 is designated by positioning the cursor and releasing (so-called mouse up) the state in which the first operation unit 31 is clicked (pressed).

  When the operation described in FIGS. 4B to 4D is performed, in the present embodiment, as shown in FIG. 4E, the graphic drawing unit 14 sets two coordinate points P1 and P2. A thick circle C1 in the drawing having a diameter of a distance between the two coordinate points P1 and P2 is superimposed on the image of the workpiece 121 displayed on the display unit 20 and drawn as a basic line having a predetermined line width. The In other words, the user can draw a circle C1 that roughly overlaps the outer edge portion of the columnar portion F1 by the operation described in FIGS. 4B to 4D.

  In the present embodiment, when the user rotates the mouse wheel 33 of the mouse 30 in one direction, the processing range setting unit 15 is drawn by the graphic drawing unit 14 as shown in FIG. The width of the basic line of the circle C1 is increased to define an annular region R1 indicated by a two-dot chain line, and a region surrounded by the outline of the annular region R1 is displayed as a candidate for the processing target range. It is possible. This annular region R1 is displayed so as to be visible in a visible manner.

  Here, as indicated by the arrows in FIGS. 4E and 4F, the processing range setting unit 15 of the present embodiment increases the line width of the circular C1 as the mouse wheel 33 rotates in one direction. Is gradually increased by equal distances in the inner diameter direction and the outer diameter direction. The increased line width can be decreased by rotating the mouse wheel 33 in the direction opposite to the direction in which the mouse wheel 33 is increased (in the other direction).

  Then, the user adjusts the annular region R1 to a desired width by operating the mouse wheel 33, and then clicks (presses) the first operation unit 31, for example, to determine the processing target range. FIG. 5 shows an outer edge portion of the cylindrical portion F1 or an image D1 around it that is set (determined) as the processing target range. In the present embodiment, the image D1 is displayed in a display area A2 different from the display area A1 in the display unit 20 (see FIG. 3).

  As described above, in the present embodiment, as shown in FIG. 4, for example, when it is desired to set the outer edge portion of the circular region or the periphery thereof as the processing target range, the circular shape that roughly overlaps the outer edge portion is circular. An annular region having a desired width is drawn by the figure drawing unit 14 as the drawing unit, and the line width of the circular basic line drawn by the figure drawing unit 14 is arbitrarily increased by the processing range setting unit 15. The processing target range can be set as For this reason, the processing target range can be set more flexibly as an annular region having a desired width in the image displayed on the display unit 20 simply and efficiently.

  Further, in the present embodiment, the line width of the circular basic line is increased by equal distances in the inner diameter direction and the outer diameter direction. Thereby, since the figure drawing unit 14 has only to draw a circle having an intermediate diameter between the inner diameter and the outer diameter of the annular region to be set as the processing target range, the setting operation of the processing target range can be easily performed. It can be done.

  Furthermore, in the present embodiment, the line width of the circular basic line is increased in accordance with the rotation of the mouse wheel 33, so that the processing target range setting operation can be easily performed. More specifically, as the rotation of the mouse wheel 33 is advanced, the line width of the circular basic line is gradually increased by equal distances in the inner diameter direction and the outer diameter direction, and the increased line width is increased. Can be decreased by rotating the mouse wheel 33 in a direction opposite to the direction in which the mouse wheel 33 is increased (in the other direction). Therefore, a desired width setting operation can be easily performed.

(Setting of processing target range by fan-shaped area)
Next, an example in which the user sets the arcuate portion or its periphery of the curved wall portion F2 shown in FIG. 3 as a processing target range by a fan-shaped region will be described with reference to FIG.

  FIG. 6A shows the curved wall portion F2 shown in FIG. 3 in an enlarged manner. When the arc-shaped portion of the curved wall portion F2 or its periphery is set as a processing target range by a fan-shaped region, the user operates the mouse 30 to cause the figure drawing unit 14 to draw an arc.

  In this case, first, the user operates the mouse 30 to designate one coordinate point P3. In the present embodiment, as shown in FIG. 6B, the user positions the cursor at a point located on the arcuate portion of the curved wall portion F2, and performs a click operation (pressing, so-called mouse) on the first operation portion 31. Down) to designate the coordinate point P3.

  Next, the user drags the mouse 30 and designates the coordinate point P4 at the drag destination. In the present embodiment, as indicated by an arrow in FIG. 6C, the user moves the cursor along the arcuate portion of the curved wall portion F2 while maintaining the state where the first operation portion 31 is pressed. Then, the cursor is positioned at a point located in an arcuate portion different from the coordinate point P3, and the second operation unit 32 is clicked (pressed, so-called right click mouse down) to designate the coordinate point P4. After designating the coordinate point P4, the user releases the state where the second operation unit 32 is pressed.

  Next, the user further drags the mouse 30 and designates the coordinate point P5 at the drag destination. In the present embodiment, as shown in FIG. 6D, the user moves the cursor along the arcuate portion of the curved wall portion F2 while maintaining the state where the first operation unit 31 is pressed, The coordinate point P5 is designated by positioning the cursor at a point located in an arc-shaped portion different from the coordinate points P3 and P4 and releasing the state where the first operation unit 31 is pressed (so-called mouse up).

  By performing the operations described with reference to FIGS. 6B to 6D, in the present embodiment, as shown in FIG. 6E, the graphic drawing unit 14 causes the three coordinate points P3 and P4. , P5 in the drawing, a thick circular arc C2 is superimposed on the image of the workpiece 121 displayed on the display unit 20 and drawn as a basic line having a predetermined line width. That is, by the operation described in FIGS. 6B to 6D, the user can draw an arc C2 that roughly overlaps the arc-shaped portion of the curved wall portion F2. The arc C2 of the present embodiment is an arc with a predetermined radius of curvature that passes through the coordinate points P3, P4, and P5. The radius of curvature of the arc is appropriately calculated according to the three coordinate points.

  In the present embodiment, when the user rotates the mouse wheel 33 of the mouse 30 in one direction, the processing range setting unit 15 is drawn by the graphic drawing unit 14 as shown in FIG. The line width of the basic line of the arc C2 is increased to define a fan-shaped region R2 indicated by a two-dot chain line, and a region surrounded by the contour of the fan-shaped region R2 is displayed as a candidate for a processing target range. It is possible. The fan-shaped region R2 is displayed so as to overlap the image in a visually recognizable manner.

  Here, as indicated by the arrows in FIGS. 6E and 6F, the processing range setting unit 15 of the present embodiment increases the line width of the arc C2 as the mouse wheel 33 rotates in one direction. Is gradually increased by equal distances in the inner diameter direction and the outer diameter direction. The increased line width can be decreased by rotating the mouse wheel 33 in the direction opposite to the direction in which the mouse wheel 33 is increased (in the other direction).

  Then, after adjusting the fan-shaped region R2 to a desired width by operating the mouse wheel 33, the user clicks (presses) the first operation unit 31, for example, to determine the processing target range. FIG. 7 shows an image D2 of the arcuate portion of the curved wall portion F2 or its periphery set (determined) as the processing target range. In the present embodiment, the image D2 is displayed in a display area A3 different from the display area A1 in the display unit 20 (see FIG. 3).

  As described above, in the present embodiment, as shown in FIG. 6, for example, when it is desired to set the arcuate part of the area having the arcuate part or its periphery as the processing target range, the arcuate part roughly overlaps. Such a circular arc is drawn by the graphic drawing unit 14 as an arc drawing unit, and the line width of the basic line of the circular arc drawn by the graphic drawing unit 14 is arbitrarily increased by the processing range setting unit 15, so that a desired width can be obtained. The processing target range can be set as a fan-shaped area. For this reason, in the image displayed on the display unit 20, the processing target range can be more flexibly set as a fan-shaped region having a desired width.

  Further, in the present embodiment, the line width of the arcuate basic line is increased by equal distances in the inner diameter direction and the outer diameter direction. Thereby, since the arc having an intermediate diameter between the inner diameter and the outer diameter of the fan-shaped region to be set as the processing target range may be drawn by the graphic drawing unit 14, the setting operation of the processing target range can be easily performed. It can be done.

  Furthermore, in the present embodiment, the line width of the arc base line is increased in accordance with the rotation of the mouse wheel 33, so that the setting operation of the processing target range can be easily performed. More specifically, as the rotation of the mouse wheel 33 is advanced in one direction, the line width of the arcuate basic line is gradually increased by equal distances in the inner diameter direction and the outer diameter direction and increased. The line width can be reduced by rotating the mouse wheel 33 in the direction opposite to the direction in which the mouse wheel 33 is increased (in the other direction). Therefore, a desired width setting operation can be easily performed.

(Processing range setting by rectangular shape)
Next, an example in which the user sets the line segment portion (side) or its periphery of the rectangular wall portion F3 shown in FIG. 3 as a processing target range by a rectangular region extending obliquely will be described with reference to FIG. .

  FIG. 8A shows the rectangular wall portion F3 shown in FIG. 3 in an enlarged manner. In the case where the line segment portion (side) or its periphery of the rectangular wall portion F3 is set as a processing target range by a rectangular region extending obliquely, the user operates the mouse 30 and sets the line segment to the graphic drawing unit 14. Let it draw.

  In this case, first, the user operates the mouse 30 to designate one coordinate point P6. In the present embodiment, as shown in FIG. 8B, the user positions the cursor at a point located at one end of the line segment portion (side) of the rectangular wall portion F3, and clicks the first operation portion 31. The coordinate point P6 is designated by (pressing down, so-called mouse down).

  Next, the user drags (moves) the mouse 30. In the present embodiment, as indicated by the arrow in FIG. 8C, the user moves along the direction in which the cursor extends obliquely of the rectangular wall portion F3 while maintaining the state where the first operation unit 31 is pressed. Then, the mouse 30 is dragged.

  Then, the user designates the coordinate point P7 at the drag destination. In the present embodiment, as shown in FIG. 8D, the user positions the cursor at a point located at the other end of the rectangular wall portion F3 and clicks (presses) the first operation portion 31. The coordinate point P7 is designated by canceling (so-called mouse up).

  When the operation described in FIG. 8B to FIG. 8D is performed, in the present embodiment, as shown in FIG. 8E, the graphic drawing unit 14 moves between the two coordinate points P6 and P7. A thick line segment C3 in the drawing is superimposed on the image of the workpiece 121 displayed on the display unit 20 and drawn as a basic line having a predetermined line width. That is, the user can draw a line segment C3 that roughly overlaps the line segment portion of the rectangular wall portion F3 by the operation described in FIGS. 8B to 8D.

  In this embodiment, when the user rotates the mouse wheel 33 of the mouse 30 in one direction, the processing range setting unit 15 is drawn by the graphic drawing unit 14 as shown in FIG. The width of the basic line of the line segment C3 is increased to define a rectangular region R3 indicated by a two-dot chain line, and a region surrounded by the outline of the rectangular region R3 is displayed as a candidate for the processing target range It is possible to do. This rectangular region R3 is displayed so as to overlap the image in a visually recognizable manner.

  Here, as indicated by the arrows in FIGS. 8E and 8F, the processing range setting unit 15 according to the present embodiment advances the rotation of the mouse wheel 33 in one direction, and the line C3 The width is gradually increased by equal distances in both directions orthogonal to the line segment C3. The increased line width can be decreased by rotating the mouse wheel 33 in the direction opposite to the direction in which the mouse wheel 33 is increased (in the other direction).

  Then, after adjusting the rectangular region R3 to a desired width by operating the mouse wheel 33, the user clicks (presses) the first operation unit 31, for example, to determine the processing target range. FIG. 9 shows an image D3 of the line segment portion of the rectangular wall portion F3 set (determined) as the processing target range. In the present embodiment, the image D3 is displayed in a display area A4 different from the display area A1 in the display unit 20 (see FIG. 3).

  As described above, in the present embodiment, as shown in FIG. 8, for example, when it is desired to set an obliquely extending line segment part or its periphery as a processing target range, the obliquely extending line segment part roughly overlaps the obliquely extending line segment part. An arbitrary line segment is drawn by the graphic drawing unit 14 as a line drawing unit, and the line width of the basic line drawn by the graphic drawing unit 14 is arbitrarily increased by the processing range setting unit 15 so as to be oblique The processing target range can be set as a rectangular region that extends and has a desired width. For this reason, the processing target range can be set more flexibly as a rectangular area having a desired width in the image displayed on the display unit 20 simply and efficiently.

  In the present embodiment, the line width of the basic line is increased by equal distances in both directions orthogonal to the line. As a result, a line segment that overlaps the center line of the rectangular area that is desired to be set as the processing target range may be drawn by the graphic drawing unit 14, so that the processing target range setting operation can be easily performed. ing.

  Furthermore, in the present embodiment, the line width of the basic line is increased in accordance with the rotation of the mouse wheel 33, so that the setting operation of the processing target range can be easily performed. More specifically, as the rotation of the mouse wheel 33 is advanced in one direction, the line width of the basic line is gradually increased by equal distances in both directions orthogonal to the line and increased. The line width can be reduced by rotating the mouse wheel 33 in the direction opposite to the direction in which the mouse wheel 33 is increased (in the other direction). Therefore, a desired width setting operation can be easily performed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and includes various modifications and the like in the above-described embodiments. For example, another known method may be employed for drawing a circle, an arc, or a line segment by the figure drawing unit 14. For example, when one coordinate point is designated by clicking the mouse 30 or the like and the mouse is dragged from the coordinate point, a circle is drawn with the distance between the coordinate point and the coordinate point being dragged as a diameter. May be.
