Of course, these image data may be stored in another appropriate recording medium. The image data storage unit 7a
Stores a sample image or the like that is used as a reference for image measurement.

The recording medium reading section 51 and the program memory 53 are connected to the bus line 13. Examples of the computer-readable recording medium on which the image measurement program according to the present invention is recorded include CD-R, CD-ROM, and D-ROM.

On these recording media, a procedure for displaying one or more measured images, a procedure for measuring the displayed image, a procedure for performing image processing after measurement, and a procedure for performing image processing and then measuring again And a program for executing each of the steps. The recording medium reading unit 51 reads various programs and data stored in a recording medium such as a CD-R, a CD-ROM, a DVD, and a floppy disk. Then, the recording medium reading unit 51
The various programs and data read by are temporarily stored in the program memory 53. Of course, these various programs and data may be stored in another appropriate recording medium.

The image processing unit 55 and the re-measurement unit 57 are connected to the bus line 13. The image processing unit 55 is an image processing unit for performing simple image processing when it is determined that there is a measurement omission or an excessive measurement after the measurement by the measurement processing unit 21. The re-measurement unit 57 is a re-measurement unit for performing measurement again after performing the above-described image processing.

Next, the operation will be described. First, a computer-readable recording medium on which an image measurement program is recorded, that is, a recording medium such as a CD-R, a CD-ROM, a DVD, and a floppy disk is mounted on the recording medium reading unit 51, and the program and data are read. The programs and data read by the recording medium reading unit 51 are temporarily stored in the program memory 53. Thereafter, the image measurement program is set up, that is, the instool is installed. Next, for example, image data on cancer cells from an electron microscope is taken in from the image data supply device 47 via the interface circuit 49, and is temporarily stored in the image data storage unit 7a.

Next, the operator operates the keyboard 5a to display an image to be measured on the display device 9 based on, for example, image data on cancer cells stored in the image data storage section 7a. That is, based on the image measurement program stored in the program memory 53, the CPU 15 stores the image data relating to the cancer cells in the image data storage unit 7a.
And supplies it to the display control unit 33. As a result, an image to be measured relating to the cancer cells is displayed on the display device 9. In the display device 9, each pixel (pixel) is shaded or colored,
A measured image of a cancer cell is expressed as a digital quantity of other features. Each pixel displayed at this time is displayed in color, and has a total information amount of 24 bits of 8 bits for each of the color information R, G, B (red, green, blue). Needless to say, each pixel has an appropriate bit number of 8 bits or more, for example, 12 bits.
Bits, 24 bits, 36 bits, or the like.
Further, the display device 9 may be configured to display a monochrome grayscale image.

Next, the case of measuring the area of the image to be measured will be described with reference to FIG. When the image to be measured is displayed as shown in FIG. 3, first, the measurement mode setting unit 60 sets the area measurement mode. Then, an appropriate magnification is selected from the magnifications preset in the pull-down menu of the area 61. In this case, a microscope that supplies image data,
An appropriate magnification is set according to the magnification of the lens, the digital camera, the photographing conditions, and the like. Next, while operating the color extraction button 63, the operator operates the mouse 5b and clicks with the cursor positioned on the image to be measured. Thereby, the same color as the image to be measured is extracted, and the values of the color information R, G, B are stored in the area 6.
5 is displayed. Further, a numerical value of the color difference is input to the area 66.

Next, the operator sets a rectangular measurement area 67 as shown in FIG. 3 by dragging the display screen with the mouse 5b so as to include the range to be measured. Thereby, the CPU 15 sets the measurement area 67
Of the images existing in the image, the color of the color which is the same as or similar to the extracted color information, that is, the color which is within the range of the color difference set in the area 66 is selected, and the areas of the images are measured. I do. At this time, the CPU 15 counts the number of pixels of the selected image, calculates the total number of pixels with reference to the aforementioned magnification, displays the numerical value in the area 75, and measures the area corresponding to the total number of pixels. The value is displayed in the area 69. When such measurement processing is completed, the color of the measured image is forcibly changed to a specific color, so that the operator can easily determine whether there is an image of measurement error or an image of excessive measurement. Can be determined. Note that the measurement area 67 is not limited to a rectangular shape, and can be set to an appropriate shape such as a closed curve.

As a result of the first measurement, if there is an image of a measurement error, re-measurement can be performed after performing simple image processing. For example, when there is an image that has not been measured in spite of an image to be measured, the operator can set the image processing mode and perform image processing on the image of the measurement error. For example, by operating the mouse 5b, the operator can paint the image of the measurement error with the same color as the extracted color information R, G, B. When the operator operates the mouse 5b and presses the re-measurement button 71, the operator selects an image having the same color as the extracted color information and a color similar to the extracted color information from the images existing in the measurement area 67. Re-measure the area of the image. Then, by operating the add button 73, the measurement value by the re-measurement is displayed in the lower row of the area 75.

Further, when there is an image that has been measured even though the image is not an image to be measured, the operator sets the image processing mode and performs image processing on the image that has been measured too much. Can be. For example, the operator has a mouse 5
By operating b, it is possible to paint over-measured images with a color different from the extracted color information R, G, B, for example, white. When the operator operates the mouse 5b and presses the re-measurement button 71, the operator selects an image having the same color as the extracted color information and a color similar to the extracted color information from the images existing in the measurement area 67. Is re-measured. As a result, the image of the over-measurement painted out in white is excluded from the measurement target.

In the above example, the case where a so-called painting is performed as the image processing in the case where there is an image of a measurement error has been described. However, the present invention is not limited to this. For example, shading correction,
Image processing such as contrast adjustment and threshold correction can be performed. Alternatively, the image to be measured may be grouped in advance for each size or type, and the area of the image to be measured may be measured for each group.

Next, a case where the number of images is measured will be described with reference to FIG. First, the measurement mode setting unit 60 sets a counter mode. When measuring an image, if it is desired to group the images to be measured by size or type, eight buttons 81a to 81h are provided for setting an arbitrary group. Here, for example, the red group button 81a is pressed.
Next, when the operator positions the cursor on the image to be measured and clicks, a red number “1” is added to the image. Further, when the cursor is placed on the next image to be measured and clicked, a red number “2” is added to the image. Similarly, every time the cursor is placed on the image to be measured and clicked,
A red number is counted up on the image and sequentially added. Next, in order to measure the image of another group, for example, the green group button 81b is pressed.
Next, when the operator positions the cursor on the image to be measured and clicks, a green number “1” is added to the image. Further, when the cursor is placed on the next image to be measured and clicked, a green number “2” is added to the image. Similarly, every time the cursor is placed on the image to be measured and clicked,
A green number is counted up on the image and sequentially added. Next, when the operator presses the display button 83, the number of measured images is displayed for each group.

If there is an image of a measurement error as a result of the above measurement, the measurement can be performed again after performing the above-described simple image processing.

Next, another embodiment in which the number of images is measured will be described with reference to FIG. First, the measurement mode setting unit 60 sets a counter mode. When measuring an image, if it is desired to group the images by the size or type of the image to be measured, eight buttons 81a to 81h are provided for setting an arbitrary group, and each button is provided. Sample displays 91a to 91h set corresponding to 81a to 81h are provided. Here, the sample displays 91a to 91h are set to specific sizes or shapes in order to perform grouping by image size or image type. For example, if you want to measure plankton in lakes and marshes, for each type of plankton,
Buttons 81a to 81h and sample displays 91a to 91h
Can be assigned. Thus, for each type of plankton, the buttons 81a to 81h and the sample display 9
The case where 1a to 91h are assigned will be described. For example, when assigning a red group button 81a to plankton A having a relatively large shape, the corresponding sample display 91a is pressed. When the sample display 91a is pressed, a size setting screen is displayed, and the size range of plankton A is set. Similarly, for medium-sized plankton B, yellow group button 8
1d and the range of the size can be set.

As described above, the size of the plankton can be set for each type of plankton.
An image in a set size range can be selected from a plurality of measured images and automatically measured. That is,
When the operator operates the mouse 5b and presses the group button 81a, an image within the range of the size set as the plankton A is automatically selected from the plurality of measured images displayed on the screen, The number is measured. At this time, a red number is counted up on the measured image and sequentially added. Similarly, when the operator operates the mouse 5b and presses the group button 81d, an image within the range of the size set as the plankton B is automatically selected from the plurality of measured images displayed on the screen. Then, the number is measured. At this time, a yellow number is counted up on the measured image and sequentially added. Next, when the operator presses the display button 83, the number of measured images is displayed for each group.

If there is an image of a measurement error as a result of the above measurement, the measurement can be performed again after simple image processing.

Next, a case where the length of an image is measured will be described with reference to FIG. First, the measurement mode setting unit 60 sets the length measurement mode. When measuring an image, if it is desired to group the images to be measured by size or type, eight buttons 81a to 81h are provided for setting an arbitrary group. Here, for example, the red group button 81a is pressed.
Next, the operator designates between any two points on the image by placing the cursor on the image to be measured and clicking on the image. Then, a red number “1” is added to that location. Further, when any two points are designated by placing a cursor on a point to be measured, a red number “2” is added to the point. Similarly, each time a cursor is placed on a location to be measured and any two locations are designated, a red number is counted up and added to that location in sequence.

Next, in order to measure the image of another group, for example, a green group button 81b is pressed.
Next, when the operator positions the cursor on the image to be measured and designates any two points, a green number “1” is added to the point. Further, when any two points are designated by placing a cursor on a point to be measured, a green number “2” is added to the point. Similarly, when an arbitrary two points are designated by placing a cursor on a point to be measured, a green number is counted up at that point and sequentially added. Next, when the operator presses the display button 85, the measured values are displayed for each group. At this time, the CPU 15 counts the number of pixels existing on a straight line between the designated points,
The length corresponding to the total number of pixels is displayed as a measured value on another screen with reference to the above-described magnification and the like.

In the above-described example, the case where the arbitrary two points are designated to measure the linear distance between the two points has been described. However, the present invention is not limited to this. The distance between them can be measured. For example, the length of an arbitrary curve designated by dragging a mouse can be measured. As shown in FIG. 7, when measuring the length between any two points, an image of another screen is displayed on this measurement screen, for example, an image 101 to be measured as a reference sample image, An image 103 that is not to be measured can be displayed. Of course, such a reference sample image can be displayed on the area measurement screen and the image number measurement screen.
