〔Method of operation〕
Next, the operation of the image measuring device 1 according to the first embodiment and the operation of the image measuring device 1 associated therewith will be described with reference to FIG. FIG. 3 is an image diagram showing a display example of an image displayed on the touch panel 4 of the image measuring device 1 according to the first embodiment.

  When the user turns on the information processing apparatus 2, an operating system (OS) is activated, and when the touch panel 4 is turned on, an icon for enlarging an image on the screen of the touch panel 4 and screen color correction are performed. A plurality of icons such as an icon for performing the operation are displayed. When the user presses an icon indicating an image measurement menu from among them, the image measurement program stored in the storage device 11 is activated.

  Hereinafter, the user's operation based on the image measurement program and the operation of the image measuring machine 1 will be described.

  When the image measurement program is activated, an image measurement tool bar 29 as shown in FIG. 3A and a sample image P1 on the electric stage 8 captured by the sample observation device 3 are displayed.

  The tool bar 29 displays icons indicating functions for measuring the distance between two points, measuring the diameter and circumference of a circle, measuring the angle, and measuring the distance from a single straight line to a plurality of points. . Although details of the icon display are omitted in the drawings, it is preferable to use symbols and figures that allow the user to easily understand the contents of the function used by pressing the icon. Note that the position and size of the tool bar 29 are not limited to those shown in FIG. 3A, and the user can change the position and size by setting.

  When an icon indicating a measurement function to be executed by the user is pressed from a plurality of icons on the toolbar 29, an image enlargement icon 30 and a measurement point designation icon 31 are displayed on the right side of the screen as shown in FIG. . At the time of display, the information processing apparatus 2 recognizes that the image enlargement icon has been selected, and is displayed on the touch panel 4 so that the image enlargement icon 30 is depressed and depressed. Note that the positions and sizes of the image enlargement icon 30 and the measurement point designation icon 31 are not limited to these, and the user may be able to change the position and size according to settings.

  In this state, when the user presses the position where the image is desired to be enlarged, as shown in FIG. 3C, the image is enlarged around the pressed point. In FIG. 3C, the left side of the drawing shows the image before enlargement, and the right side shows the image enlarged around the point pressed.

  The enlargement ratio of the image may be determined in advance, but the user may be allowed to set how much enlargement ratio is used for one enlargement. In addition, the touch panel 4 may be a pressure-sensitive touch panel, and the enlargement ratio may be changed according to the pressing pressure sensed by the touch panel 4. For example, when the pressing pressure is high, the display magnification is high, and when the pressing pressure is low, the display magnification is low.

  When the part to be specified is sufficiently enlarged and the user presses the part to be measured after pressing the measurement point designation icon 31, the information processing apparatus 2 confirms the measurement point, and a mark indicating the measurement point on the touch panel 4 33 is displayed. On the other hand, if it is determined that the part that the user wants to specify is not sufficiently enlarged, the image enlargement icon 30 remains selected unless the measurement point designation icon 31 is pressed, and the user presses the point that the user wants to enlarge again. Then, after the image is sufficiently enlarged, the measurement point designation icon 31 is depressed to depress the position to be the measurement point. When the measurement point designation icon 31 is pressed but the user determines that the image is not sufficiently enlarged, the information processing apparatus 2 can enlarge the image again by pressing the image enlargement icon 30 Returned to The position of the measurement point may be adjusted by dragging a mark indicating the measurement point after designating the measurement point. When adjustment by dragging is possible, as described in the second embodiment below, it may have a function of adjusting a deviation between coordinates sensed by the touch panel and a point designated by the user.

  The measurement points can be specified by specifying two points if measuring between two points, and specifying three points on a circle if measuring the diameter and circumference of a circle. Do it accordingly. When the user touches the measurement point designation icon 31 and designates the measurement point, it is preferable that the information processing device 2 displays on the touch panel 4 how the measurement point needs to be designated.

  When a plurality of measurement points are specified, when the first measurement point is specified, the image displayed on the touch panel 4 returns to the state shown in FIG. Repeat the same operation as the measurement point designation until all measurement points are designated.

  When all the measurement points are specified, image measurement is performed by the information processing apparatus 2, and an image of the sample before enlargement is displayed on the touch panel 4 as shown in FIG. Is displayed (overlaid). For example, in measuring the distance between two points, the length per pixel of the image is calculated from the distance between the pixels of the CCD and the magnification of the image, and the length of the image existing between the two points is calculated based on the length. This can be done by multiplying the number of pixels. Alternatively, the reference length per pixel of the reference magnification image is measured in advance using a scale, the length per pixel is calculated from the reference length and the actual image magnification, and the length Can be multiplied by the number of pixels present between the two points. In measuring the area, the distance required for calculating the area can be measured and calculated, and the area per pixel is calculated by multiplying the magnification of the image. It can be calculated by multiplying the number of pixels contained in the face being formed.

[Enlargement of sample image]
For the above-described enlargement of the sample image, either a method using an optical zoom or an electronic zoom alone or a method using both an optical zoom and an electronic zoom can be used. As an example of optical zoom, a digital microscope “ShuttlePix” (registered trademark) having an optical zoom magnification of 20 times is commercially available.

  When the optical zoom is used, when the user designates a center point other than the center point that the image capturing device 6 is capturing at that time as the center point of enlargement, the information processing device 2 determines (X, Y) coordinates between the center points. , And an instruction for the moving direction and the moving distance is issued from the information processing device 2 to the electric stage 8 so that the designated portion of the sample is positioned at the center of the image captured by the imaging device 6. While 8 moves the sample, the position detection is performed by the stage position detection unit 32, and the position is adjusted. Further, the information processing device 2 instructs the electric zoom mechanism 20 to increase the zoom magnification, the electric zoom mechanism 20 increases the zoom magnification, the imaging device 6 images the sample, and the captured image data is processed. Output to device 2.

  On the other hand, when the electronic zoom is used, the central processing unit 12 performs the electronic zoom around the portion where the user touches the touch panel 4 as the center point of enlargement. Although the image measuring device 1 according to the first embodiment includes the sample observation device 3, when only the electronic zoom is used, the sample observation device 3 may not be provided. For example, image data that has already been captured. Can be read out from the storage device 11 and the image data can be enlarged and used by electronic zoom.

  When the optical zoom and the electronic zoom are used in combination, the electronic zoom is used up to a magnification at which the resolution of the touch panel 4 and the resolution of the image are equal, and the image is enlarged using the optical zoom after the resolution is equal. After the optical zoom reaches the maximum magnification, the electronic zoom is used again. Thereby, optical resolution and image resolution can be used efficiently.

〔Edge detection〕
When designating measurement points, feature points obtained by edge detection can be displayed on the touch panel 4 as measurement point candidates. For example, as shown in FIG. 4A, feature points for edge detection are displayed together with numbers, and the measurement point is fixed at the position of the feature point when the user presses the numbered mark. To do. Or when an image measuring machine is equipped with a keyboard, a measurement point is decided in the position of the feature point by designating a number with a keyboard. Note that the shape of the mark is not limited to this, and may not be numbered when the keyboard is not used. As the edge detection method, a known method such as a Canny method or a differential edge detection method can be used.

  It is preferable that display of the feature points can be switched between display and non-display by an operation on the touch panel. For example, as shown in FIG. 4B, the feature points can be switched between display and non-display by dragging a circle on the surface of the touch panel 4. Further, as shown in FIG. 4C, the feature points can be switched between display and non-display by continuously pressing twice (double touch) a portion other than the feature points of the touch panel 4. .

(Second Embodiment)
Next, an image measuring machine according to a second embodiment of the present application will be described. The hardware configuration of the image measuring machine according to the second embodiment is the same as that of the image measuring machine 1 according to the first embodiment. Since the image measuring machine according to the second embodiment is different from the image measuring machine according to the first embodiment in the operation of the user and the operation of the image measuring machine based on the image measuring program, this will be described below. Note that the same reference numerals as those in FIGS. 1 and 2 are used in the description of the second embodiment.

  FIG. 5 is an image diagram showing a display example of an image displayed on the touch panel 4 of the image measuring machine according to the second embodiment.

  When the user turns on the information processing apparatus 2, an operating system (OS) is activated, and when the touch panel 4 is turned on, an icon for enlarging an image on the screen of the touch panel 4 and screen color correction are performed. A plurality of icons such as an icon for performing the operation are displayed. When an icon indicating an image measurement menu is pressed from among them, an image measurement program stored in the storage device 11 is activated.

  When the image measurement program is activated, the imaging apparatus captures a high-resolution live image P1 for each frame rate into the RAM in the information processing apparatus 2 (hereinafter, this live image is referred to as “frame image”). The frame image data captured in the RAM is combined with the image of the image measurement tool bar 32 as shown in FIG. 5A, output from the information processing apparatus 2 to the touch panel 4, and displayed on the touch panel 4. In general, the touch panel 4 often has a lower resolution than the frame image. In this case, the entire frame image is displayed in accordance with the size and resolution of the touch panel 4.

  When the user presses the part of the touch panel 4 on which the part to be a measurement point is displayed while looking at the image displayed on the touch panel 4, as shown in FIG. 5B, for example, from the touch panel 4 Based on the output data, the information processing device 2 determines a circle centered on the coordinates determined to be a point designated by the user and a broken cross line passing through the center of the circle (hereinafter, the circle and the cross line are Is called on the touch panel 4 and the user can accurately recognize the position of the coordinates. As a result, even if a deviation occurs between the coordinates intended by the user on the touch panel 4 and the coordinates detected by the touch panel 4, the user can accurately know the position determined by the image measuring machine 1 as the designated point. it can. The display of the designated point is not limited to a circle and a dashed cross line, and for example, a square and its diagonal line may be free of circles and squares, and various changes can be made.

  When the user presses the touch panel 4 with a finger or a pen, the user usually makes contact with the touch panel 4 with a certain area. In this case, the information processing apparatus 2 assumes that the center point is designated. Processing may be performed, or processing may be performed assuming that a predetermined portion within the range is designated. However, when the user presses with a finger or the like, since the user cannot see the image of the part hidden by the finger or the like, the information processing apparatus 2 is separated from the contact range by a predetermined distance in a predetermined direction. Processing may be performed assuming that the position is designated. For example, the information processing apparatus 2 can perform processing assuming that a position away from the uppermost portion of the contact range by about 3 cm is designated. In this case, the distance from the contact range and the direction away from the contact range may be changed by the user according to settings.

  When the user presses a portion to be measured in the image displayed on the touch panel 4, the information processing apparatus 2 holds the frame image at the time when the touch panel is pressed on the RAM (hereinafter, this The frame image is referred to as “holding frame image”). Then, the coordinate data pressed from the touch panel 4 is output to the information processing apparatus 2, and the imaging apparatus captures an enlarged image centered on a point determined by the information processing apparatus 2 as the designated point from the coordinate data. 6 receives the instruction, and the imaging device 6 having received the instruction increases the optical magnification, captures an enlarged image of the sample centered on the specified point, and outputs the image data to the information processing device 2. The movement and adjustment of the image capturing position are the same as those in the first embodiment.

  In order for the touch panel 4 to display an enlarged image, in addition to imaging with the optical magnification being increased as described above, the output resolution of the imaging apparatus is operated to a high resolution, or the image is enlarged by electronic zoom in the information processing apparatus 2 You can also do it.

  The information processing apparatus 2 that has received the image data output from the imaging device 6 synthesizes an enlarged image (live image) output from the imaging device 6 for each frame rate together with the display of the designated point on the holding frame image. As shown in FIG. 5B, the touch panel 4 displays the image (hereinafter, a range enlarged from the holding frame image is referred to as “attention range”).

  The display of the designated point and the size of the attention range (hereinafter simply referred to as “the width of the attention range”) are determined with the touch panel 4 having a pressure sensing function, and the information processing apparatus 2 senses the touch panel 4. It may be changed according to the pressing pressure. For example, the user can adjust the size of the attention range by an intuitive operation by widening the attention range when pressed hard and narrowing the attention range when weak. It is preferable that the user can adjust how much the range of the attention range changes depending on the pressing pressure.

  Alternatively, the touch panel 4 may be provided with a pressure sensing function, and the display magnification of the image in the range of interest may be changed by the information processing apparatus 2 according to the pressing pressure sensed by the touch panel 4. For example, when the button is pressed strongly, the display magnification of the attention range is high, and when it is weak, the display magnification of the attention range is low. Thus, the user can adjust the display magnification by an intuitive operation. It is preferable to allow the user to adjust how much the display magnification changes depending on how much pressure is pressed.

  Or, by combining these, the range of interest and the display magnification can be set so that the area of interest is wide and the display magnification is high when pressed hard, and the area of interest is narrow and the display magnification is low when pressed weakly. The processing device 2 may perform processing.

  When the optical zoom and the electronic zoom are used together, the image is enlarged using the electronic zoom up to a magnification at which the resolution of the touch panel 4 and the resolution of the image are the same as in the first embodiment. When the image is magnified using the optical zoom and the optical zoom reaches the maximum magnification, the electronic zoom can be used again.

  When the specified point displayed by pressing the touch panel 4 is different from the intended position, the user moves (drags) the finger pressing the touch panel 4 on the touch panel 4 while pressing the touch panel 4. Then, the information processing apparatus 2 processes the display of the designated point and the attention range so as to follow it. When the user determines that the designated point has overlapped with the intended point, when the user releases his / her finger from the touch panel 4, the information processing apparatus 2 determines the position of the designated point at that time as a measurement point, and the touch panel 4 performs measurement. A mark indicating the point is displayed. According to the second embodiment, since the attention range is displayed after the entire image is displayed, the user can easily recognize which part of the entire image the attention range indicates.

  The information processing apparatus 2 preferably has a function of adjusting a deviation between a designated point intended by the user and coordinates detected by the touch panel. Specifically, the position of the designated point (position 1) when the user first presses the touch panel 4 as a measurement point instruction and the finger that the user moves and presses by a drag operation from the touch panel 4 are displayed. When the position (position 2) of the measurement point that has been set apart is stored, a plurality of pairs of position 1 and position 2 can be stored, and the movement direction and distance of position 1 and position 2 can be confirmed Moreover, the information processing apparatus 2 considers that there is a difference between the recognition point on the touch panel and the designated point intended by the user, and adjusts the position of the designated point. For example, when the measurement point is specified three times and the position 2 is shifted to the right with respect to the position 1 three times, the recognition point of the touch panel is shifted to the right of the position 1 and the position 2 from the next time. Assuming that a point shifted to the right is indicated for the average of the three times, The same applies to the vertical direction.

  FIG. 6 shows a flow from the start of measurement to the completion of measurement in the second embodiment.

  As illustrated in FIG. 7A, the information processing apparatus 2 may output image data in which feature points obtained by edge detection within a range of interest are displayed as measurement point candidates to the touch panel 4. For example, when a feature point for edge detection is displayed together with a number, and the designated point is superimposed on the feature point number by a drag operation on the touch panel 4, the designated point moves to the feature point. When the finger or the like pressed from the panel is released in this state, the information processing apparatus 2 determines the position of the feature point as a measurement point and displays a mark on the touch panel 4. In order to designate other feature points or portions other than the feature points after the designated point display has moved to the feature points, the designated point can be displayed by dragging a finger or the like holding down the touch panel 4 over a certain distance. It is processed by the information processing device 2 so as to return to the state before being superimposed on the feature point number away from the feature point.

  The display and non-display of the feature points may be switched according to a user instruction. For example, as shown in FIG. 7B, when the information processing apparatus 2 detects that a circle is drawn on the touch panel 4 with a finger or the like pressed to specify a measurement point, You may make it switch non-display. Alternatively, the touch panel 4 is set as a multi-touch panel capable of detecting a plurality of contact points, a touch FLO, or the like, and a designated point is designated outside the attention range near the measurement point as shown in FIG. 7C. The display and non-display of feature points may be switched by double touching with a finger other than the finger or the like.

  When all necessary measurement points are designated, the length and the like are calculated by the information processing device 2 as in the first embodiment, and image data in which the measurement result is overlaid on the frame image is output. It is displayed on the touch panel 4 as shown in FIG.

(Third embodiment)
Next, an image measuring machine according to a third embodiment of the present application will be described. The hardware configuration of the image measuring machine according to the third embodiment is the same as that of the image measuring machine according to the first embodiment. Since the image measuring machine according to the third embodiment is different from the image measuring machine according to the first embodiment in the operation of the user and the operation of the image measuring machine based on the image measuring program, this will be described below. Note that the same reference numerals are used in the description of the third embodiment as the reference numerals described in FIGS. 1 and 2.

  The third embodiment is different from the second embodiment in the operation of the user specifying the measurement point based on the image measurement program and the operation of the image measuring machine 1, but otherwise the second embodiment. It is the same. Therefore, a different part from 2nd Embodiment is demonstrated below.

  FIG. 8 is a flowchart showing the flow of processing from the start of measurement to the end of measurement of the image measuring machine according to the third embodiment.

  In the third embodiment, after the user presses an icon indicating the image measurement menu from the menu screen to start the image measurement program, for example, the user presses the touch panel 4 with the finger of the left hand (1 Second press). This pressing with the left hand has nothing to do with the position of the measurement point, but simply causes the information processing apparatus 2 to recognize that the measurement point designation is continued. The user presses a point to be a measurement point with the finger of the right hand while continuing pressing with the left hand (second press). The information processing apparatus 2 that has recognized that the second press has been performed outputs image data obtained by combining the display of the designated point and the image of the attention range to the holding frame image, as in the second embodiment.

  The information processing apparatus 2 does not fix the measurement point unless the left hand is pressed away from the touch panel 4. Therefore, the user may release the right hand from the touch panel 4 once. Even if the right hand is released from the touch panel 4, the attention range continues to be displayed at the position where the right hand last pressed the touch panel 4, and when the user moves the specified point, the touch area is again pressed by the right hand and moved. be able to.

  When the user determines that the designated point has overlapped with the position to be the measurement point, when the user moves his left hand away from the touch panel 4, the information processing apparatus 2 thereby determines the position of the designated point as the measurement point. By configuring in this way, unlike the second embodiment, the position of the measurement point is specified while viewing the entire image displayed on the touch panel 4 without hiding the touch panel 4 with the finger, hand, arm, etc. that moves the specified point. can do.

  In the second and subsequent drags after the drag is released once, the position where the finger is first pressed with the finger or the position where a certain distance is removed from it is the same as the first drag. As the designated point, the information processing apparatus 2 may be configured so that the attention range moves following the drag, or the designated point designated in the first drag is different from the first drag. The information processing apparatus 2 may perform processing so that the range of interest moves in conjunction with the drag while maintaining the positional relationship with the position pressed first in the second and subsequent drags.

  As described in the second embodiment, when the size of the attention range or the display magnification is changed according to the pressing pressure of the touch panel 4, or when the size of the attention range and the display magnification are changed, the above example When the pressure with which the touch panel 4 is pressed down by the right hand that moves the designated point decreases at a certain rate of change or more and leaves, the information processing apparatus 2 is not an instruction to change the size of the range of interest or the display magnification. It is also possible to recognize and maintain an image of the range of interest or display magnification before the pressing pressure is reduced. Alternatively, when the right hand that moves the designated point moves away, the information processing apparatus 2 may output image data having a preset range of interest or display magnification.

(Fourth embodiment)
Next, an image measuring machine according to a fourth embodiment of the present application will be described. The hardware configuration of the image measuring machine according to the fourth embodiment is the same as that of the image measuring machine according to the first embodiment. Since the image measuring machine according to the fourth embodiment is different from the image measuring machine according to the first to third embodiments in the operation of the user and the operation of the image measuring machine based on the image measuring program, this will be described below. To do. The same reference numerals are used in the description of the fourth embodiment as the reference numerals described in FIGS. 1 and 2.

  The fourth embodiment is partially different from the second embodiment in the operation of the user specifying the measurement point based on the image measurement program and the operation of the image measuring machine 1, but otherwise the second embodiment. It is the same. Therefore, a different part from 2nd Embodiment is demonstrated below.

  FIG. 9 is a flowchart showing the flow of processing from the start of measurement to the end of measurement of the image measuring machine according to the fourth embodiment.

  In the fourth embodiment, when the user presses the touch panel 4 after starting the image measurement program by pressing an icon indicating an image measurement menu from the menu screen, the information processing apparatus 2 Is output, and the touch panel 4 displays the image. Up to this point, the process is the same as in the second embodiment.

  However, the fourth embodiment differs from the second embodiment in that when the touch panel 4 is double-touched, the information processing apparatus 2 determines a designated point at that time as a measurement point. Accordingly, since the measurement point is not fixed even if the finger or the like that has pressed down the touch panel 4 is released from the touch panel 4, the user can remove the finger or the like from the touch panel 4 and view the entire image. The position can be confirmed, and if the position deviates from the intended position, the touch panel 4 can be dragged again to move the designated point. When it is determined that the display of the designated point has overlapped with the position intended by the user, when the user double-touches on the touch panel 4, the information processing apparatus 2 determines the position of the designated point at that time as the measurement point.

  Note that the third embodiment is described with respect to the case where the designated point is moved in the second and subsequent drags after the drag is released once and the size of the range of interest or the display magnification is changed in accordance with the pressing pressure on the touch panel 4. It is the same.

(Fifth embodiment)
Next, an image measuring machine according to a fifth embodiment of the present application will be described. The hardware configuration of the image measuring machine according to the fifth embodiment is the same as that of the image measuring machine according to the first embodiment. Since the image measuring machine according to the fifth embodiment is different from the image measuring machines according to the first to fourth embodiments in the operation of the user and the operation of the image measuring machine based on the image measuring program, this will be described below. To do. Note that the same reference numerals as those in FIGS. 1 and 2 are used in the description of the fifth embodiment.

  The fifth embodiment is partially different from the second embodiment in the operation of the user specifying the measurement point based on the image measurement program and the operation of the image measuring machine 1, but the other is different from the second embodiment. It is the same. Therefore, a different part from 2nd Embodiment is demonstrated below.

  In the fifth embodiment, when the user presses the touch panel 4 after starting the image measurement program by pressing an icon indicating an image measurement menu from the menu screen, the information processing apparatus 2 Is output, and the image data obtained by combining the display of the designated point and the image of the attention range with the frame image is output, and the image is displayed on the touch panel 4. Up to this point, the process is the same as in the second embodiment.

  However, in the fifth embodiment, unlike the second embodiment, the measurement point is not fixed even if the finger pressed for the first time is released from the touch panel 4. When the user performs the second pressing and dragging, the information processing apparatus 2 moves the display of the designated point and the range of interest in conjunction with the drag while maintaining the positional relationship with the position where the specified pressing is first performed. When the finger or the like that is dragged by the second press is released from the touch panel 4, the position of the designated point at that time is determined as the measurement point, and the measurement point is displayed on the touch panel 4. As a result, the user can adjust the position of the designated point after removing the finger from the touch panel 4 and viewing the entire image displayed on the touch panel 4.

  The case where the range of interest or the display magnification is changed according to the pressure of pressing the touch panel 4 is the same as in the third embodiment.
