BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a box-type microscope apparatus, such as an optical microscope apparatus, having a housing for blocking light or protecting a specimen environment, which chiefly uses a microplate, for the purpose of the observation and/or measurement of a living specimen such as a cell.
2. Description of Related Art
Optical microscopes are generally used as means for observing living cells, in vivo, such as medium cell specimens, cultured with culture fluid on petri dishes or microplates. In recent years, the optical microscope has been combined with a high-sensitivity image pickup means, such as a cooled CCD camera, so that feeble fluorescent light is detected from the medium cell labeled by fluorescence and is recorded as image data. The fluorescent light from the medium cell labeled by fluorescence is extremely feeble, and in order to detect this feeble fluorescent light with accuracy, the detection of light other than the fluorescent light from the cell, namely, of disturbance light, must be prevented as far as possible. For this, some optical microscope apparatuses commercially available have structures such that the entire inverted microscope is covered with a housing and thereby external light is not detected at least when an image is acquired. Such a box-type optical microscope apparatus includes an electric stage on which a microplate can be placed and which is controlled by a computer and thereby can be moved in X and Y directions.
In recent motor-operated microscope systems, a system is proposed that a microscope apparatus is loaded with a personal computer (hereinafter referred as to “PC”) and thereby Graphical User Interface (hereinafter referred to as “GUI”) is used for an operation screen so that electric control can be made through the operation screen of a control program by Dynamic Link Library (hereinafter referred to as “DLL”).
The motor-operated microscope system of this type in the box-type optical microscope apparatus is set forth in the printed matter of the operation screen, for example, of (1) Molecular Devices, “MetaMorph”, [online search], http://www.nihonmdc.com/pages/UIC/metamorph.html and (2) Olympus Soft Imaging Solutions, “Scan R”.
FIGS. 1-3 are explanatory views showing the operation screen of the motor-operated microscope system described in Item (1), in which FIG. 1 shows a state where the control program is started, FIG. 2 shows a state where various window screens are opened, and FIG. 3 shows a state where a journal file production window screen is opened. This motor-operated microscope system has a boot screen 50, a camera control condition setting screen 51, a focus control condition setting screen 52, an objective control condition setting screen 53, an observation well setting screen 54, a microplate scanning condition setting screen 55, and a photographed image displaying screen 56, and is constructed so that a preset task bar shown in FIG. 1 is selected to give a command and thereby the screens 51-56 can be displayed as window screens on the boot screen 50.
The camera control condition setting screen 51 is constructed so that the exposure time of a camera and the sensitivity of binning can be set. The focus control condition setting screen 52 is constructed so that the amount of movement of the electric stage in a Z direction relative to an objective lens can be set. The objective control condition setting screen 53 is designed so that the magnification of the objective lens can be set. The observation well setting screen 54 is designed so that a desired observation well in the microplate can be set. The microplate scanning condition setting screen 55 is such that the amount of movement of the electric stage per step in the X and Y directions and the scanning order of the desired observation well in the microplate can be set. The photographed image displaying screen 56 is such that an image picked up by the camera can be displayed.
Also, in the motor-operated microscope system described in Item (1), screens for setting conditions of the brightness of illumination light and of wavelength used in the observation (for example, of an excitation filter or a barrier filter used in the observation), although not shown in FIG. 2, are additionally provided as window screens. The camera control condition setting screen 51 includes a camera operating button 51a and an image saving button 51b. The motor-operated microscope system is such that when the camera operating button 51a is pushed, image pickup is performed by the camera and when the image saving button 51b is pushed, a photographed imaged is saved in a preset storage medium. The microplate scanning condition setting screen 55 is provided with a stage operating button 55a. The motor-operated microscope system is such that when the stage operating button 55a is pushed, the electric stage is driven.
When the motor-operated microscope system provided with the control program having the operation screens constructed as mentioned above is used to carry out the observation and/or measurement of a specimen, an operator, after starting the control program to display the boot screen 50 of FIG. 1, selects the preset task bar to give a command and thereby opens the window screens 51-55 for setting individual conditions described in FIG. 2 to set a desired condition in accordance with each window screen. After the completion of the setting, the operator pushes the stage operating button 55a provided on the microplate scanning condition setting screen 55. At this time, the electric stage is operated to locate a desired specimen at an observation position. Subsequently, the operator pushes the camera operating button 51a on the camera control condition setting screen 51. At this time, the camera is operated and the image of the specimen is photographed. A picked-up image is displayed on the photographed image displaying screen 56. Next, the operator pushes the image saving button 51b provided on the camera control condition setting screen 51. At this time, the photographed image is recorded in a preset record medium. After that, a series of operations extending from the push of the stage operating button 55a to the push of the image saving button 51b is repeated with respect to all the desired observation wells set on the observation well setting screen 54. Whereby, the image pickup of the specimen in the desired observation well is completed. After this, the observation and/or measurement of the specimen can be carried out by using the picked-up image.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Before undertaking the description of the embodiment, the function and effect of the present invention will be explained.
In the motor-operated microscope system and the software for controlling motor-operated microscopes in the present invention, the operating condition setting screen is constructed to have, on one screen, a photographic condition setting section for setting an exposure condition with the image pickup means, a focus setting section for setting a focusing condition with the objective lens, an objective interchange setting section for changeover to an objective lens of a desired magnification, of the plurality of objective lenses of different magnifications, an illumination condition setting section for setting wavelength used for illumination light and luminance of illumination light, an image pickup range setting section for setting a desired image pickup range with the image pickup means in the specimen vessel, an image displaying section displaying an image picked up by the image pickup means, and an operation commanding section for commanding the operation of the motor-operated microscope section. In this way, there is no need to perform the opening and closing operation of a plurality of window screens as in the motor-operated microscope system described in Item (1) or (2) and it is avoidable that the condition setting operation and the confirmation of the setting condition become difficult due to the superposition of window screens. As a result, the load of work of the motor-operated microscope imposed on the operator carrying out various examinations for a large number of specimens can be materially reduced and work time can be made considerably efficient and rapid.
FIG. 10 is an explanatory view showing the entire structure of the motor-operated microscope system according to one embodiment in the present invention. FIG. 11 is an explanatory view showing the layout of the operating condition setting screen in the motor-operated microscope system of FIG. 10, and FIGS. 12A and 12B are a side view and a front view, respectively, of the operation screen of FIG. 11.
The motor-operated microscope system of the embodiment includes a motor-operated microscope section 10, a housing 20 incorporating the motor-operated microscope section 10, and a control device 23. The motor-operated microscope section has a transmitting illumination optical system 11, an electric stage 12, a reflecting illumination 10 optical system 13, and an image forming optical system 14. The transmitting illumination optical system 11 is placed above the electric stage 12 and is constructed so that the specimen in a specimen vessel 24 placed on the electric stage 12 is irradiated with white light or near-infrared light, for example, of wavelength 680 nm, in a vertical direction from above. The specimen vessel 24 is constructed with a microplate, for instance. In FIG. 10, reference numeral 11 a represents a light source such as a xenon lamp.

It is also designed so that when the photographic condition per well is set through the window screen of FIG. 12B, its setting value is the setting value of the photographic condition per well until the photographic condition per well is reset through the window screen of FIG. 12B.
The image displaying section 36 includes a photographed image displaying screen. This is the display item corresponding to, for example, the main photographed image displaying screen 70a on the boot screen shown in FIG. 4 or the photographed image displaying screen 73a on the photographic condition confirming screen 73 shown in FIG. 7. The operation commanding section 37 is constructed with a photography handling command button. The photography handling command button 37 has a start button 37a, an interruption button 37b, and a stop button 37c. These are the command buttons corresponding to, for example, the start button 70e1, the interruption button 70e2, and the stop button 70e3 in the automatic photography handling command button 70e of the boot screen 70 shown in FIG. 4.
Further, the operating condition setting screen shown in FIG. 11, in addition to these, has a command button 38a for photographic condition setting data input and output, a command button 38b for test photographic image processing, a first button 38c for test display, a second button 38d for test display, a command button 38e for storing an auto-focus reference position, a switching list display and designation item 39 for an observation image type according to the reagent, setting items 40 and 41 for the color channel of the fluorescent reagent and the image type, and a designation item 42 for the save location of setting condition data.

The load button 38a1 is the command button for displaying the operating condition setting data already saved in a preset storage region on the operating condition setting screen. The save button 38a2 is the command button corresponding to, for example, the save button 70f3 on the boot screen 70 shown in FIG. 4. The command button 38b for test photographic image processing has a live image displaying button 38b1, a capture button 38b2, and a save button 38b3.
The live image displaying button 38b1 is the command button for displaying a live image according to the setting condition as a photographic condition confirming image on the image displaying section 36 when the first button 38c for test display or the second button 38d for test display is pushed. The capture button 38b2 is the command button for capturing an image at a desired time point of the live image displayed on the image displaying section 36 as a still image in a preset temporary save region and displaying the still image on the image displaying section 36. The save button 38b3 is the command button for saving the still image captured through the capture button 38b2 in a preset storage region.
The first button 38c for test display is the command button which corresponds to, for example, the test displaying button 72z4 on the photographic condition setting screen 72 shown in FIG. 6 and by which an image based on the setting conditions of the photographic condition setting section 31a, the focus setting section 32a, the objective interchange setting section 33a, the illumination condition setting section 34a, and the setting items 40 and 41 relative to the image type is displayed as the photographic condition confirming image on the image displaying section 36. The second button 38d for test display is the command button which corresponds to, for example, the test displaying button 71z4 on the auto-focus setting screen 71 shown in FIG. 5 and by which an image based on the setting conditions of the photographic condition setting section 31b, the focus setting section 32b, the objective interchange setting section 33b, and the illumination condition setting section 34b is displayed as the photographic condition confirming image on the image displaying section 36.

In the motor-operated microscope system provided with the software for controlling motor-operated microscopes of the embodiment, the operator inputs desired operating conditions in various setting items whose layout is shown on the boot screen of FIG. 11. When the confirmation of setting contents is desired, the test button 38c (or 38d) is pushed and thereby the setting contents are displayed on the image displaying section 36. Whereby, according to the motor-operated microscope system provided with the software for controlling motor-operated microscopes of the embodiment, without opening window screens for setting various conditions separately opened in Items (1) and (2), the setting of the exposure condition with the image pickup means; the setting of the focusing condition with the objective lens; the setting of changeover to an objective lens of a desired magnification, of a plurality of objective lenses of different magnifications; the setting of wavelength used for illumination light and luminance of illumination light; and even the setting of a desired image pickup range with the image pickup means in the specimen vessel can be performed on a singe screen. Set data are housed in the photographic data region, not shown, and the preparation of photography for carrying out the observation and/or measurement of the specimen is completed.
Here, when the save button 38a2 is pushed, data set in FIG. 11 are saved in a preset storage region. After the preparation of photography for carrying out the observation and/or measurement of the specimen is completed, when the operator pushes the start button 37a, the control device 23 drives the electric stage 12, the light source 13a, the light source 11a, the CCD camera 14c, the cube replacing means, not shown, and the objective interchanging means, not shown, in the motor-operated microscope section 10 on the basis of the data set in FIG. 11. Whereby, the motor-operated microscope is driven and automatic photography relative to all desired observation wells is performed.
More specifically, the exposure is controlled through the CCD camera 14c on the basis of the setting information of the exposure condition with the image pickup means. In accordance with the setting information of the focusing condition with the objective lens, a relative distance in the Z direction between the objective lens 14a and the electric stage 12 is changed. Further, on the basis of the setting information of changeover to an objective lens of a desired magnification, of the plurality of objective lenses of different magnifications, a changeover is made to the objective lens 14 of the desired magnification provided to the revolver, not shown. Still further, on the basis of the setting information of wavelength used for illumination light and luminance of illumination light, amounts of light of the light sources 11a and 13a are adjusted and a changeover is made to a preset cube having the excitation filter 13b, the dichroic mirror 13c, and the barrier filter 14d, provided in the replacement means. In accordance with the setting information of a desired image pickup range with the image pickup means in the specimen vessel, the electric stage 12 is moved in the X and Y directions by a preset amount. Subsequently, the image of the specimen at the observation position is picked up through the CCD camera 14c so that an image picked up by the CCD camera 14c is displayed on the image displaying section 36 and is saved in a preset save region. Such a series of operations is performed with respect to all the desired observation wells, and thereby the image pickup of the specimen in each of the desired observation wells is completed. After this, the observation and/or measurement of the specimen can be carried out by using a picked-up image.
As mentioned above, in order to operate the motor-operated microscope, it becomes necessary to make the setting of the exposure condition with the image pickup means; the setting of the focusing condition with the objective lens; the setting of the changeover to an objective lens of a desired magnification, of the plurality of objective lenses of different magnifications; the setting of wavelength used for illumination light and luminance of illumination light; and the setting of a desired image pickup range with the image pickup means in the specimen vessel. However, in order to avoid wasting the examination result, the setting of the operating condition of the motor-operated microscope requires circumspection. Hence, it becomes necessary for the operator to confirm the setting contents after the setting of the operating condition of the motor-operated microscope. It is sometimes required that the same specimen is observed with several kinds of different wavelengths. Thus, the facilitation of a change in the operating condition of the motor-operated microscope, depending on the circumstances, is necessary for reducing physical and mental loads of the operator who carries out the examinations of a large number of specimens. However, with the window screens for a plurality of condition settings, overlapping in layers as in the motor-operated microscope system described in Item (2), the operation performed until a desired screen is opened imposes a heavy load on the operator performing the operation. Additionally, in the motor-operated microscope system described in Item (1), individual window screens are displayed at different positions in accordance with order that the window screens are opened, and thus the operation is difficult and the individual window screens overlap in a partial region so that it is hard to confirm the setting contents.
In contrast to this, according to the motor-operated microscope system provided with the software controlling motor-operated microscopes of the embodiment, all condition settings necessary for the operation of the motor-operated microscope are made on a single screen. Hence, a complicated operation that a plurality of window screens are opened in accordance with the setting contents becomes unnecessary and it is avoidable that the setting item is hidden below the window screen. In addition, each of the condition setting items is fixedly located at a constant position on the single screen and hence, unlike the motor-operated microscope system described in Item (1), even when the order of the setting of the operating condition is varied, there is no need to look for the position where a desired setting item is displayed. According to the motor-operated microscope system provided with the software for controlling motor-operated microscopes of the embodiment, therefore, maneuverability for the confirmation of the condition setting contents and the change of the setting contents is much better than in the motor-operated microscope system described in Item (1) or (2). Consequently, the load of work of the motor-operated microscope imposed on the operator carrying out various examinations for a large number of specimens can be materially reduced and work time can be made considerably efficient and rapid.
Also, the motor-operated microscope system provided with the software for controlling motor-operated microscopes of the embodiment is such that when the mouse is clicked on the well designated to be photographed in the setting item 35b for wells to be photographed on one plate shown in FIG. 12A as the additional function, the window screen for setting the photographic condition per well as shown in FIG. 12B is opened. However, the screen shown in FIG. 12B is used when the photographic range per well is set in more detail as the additional function, and even though the setting is not made, the entire range of one well is only designated to be photographed. When the setting is once made, there is little need to make again the setting each time an observation technique and the specimen are changed. Hence, even when the function of displaying the window screen of FIG. 12B is added, the maneuverability is not impaired.
Also, although the motor-operated microscope system of the embodiment is constructed so that after one operating condition is set, the motor-operated microscope is operated on the basis of its operating condition, it may be designed so that a plurality of operating conditions are together set and the motor-operated microscope is continuously operated on the basis of each operating condition. For example, when the save button 38a2 is pushed after some operating condition setting is completed, the setting contents are stored in a preset storage region so that another operating condition can be again set. In this case, processing enumerating the commands of a general-purpose program like the journal file production processing in the motor-operated microscope system of Item (1) is automatically produced inside the arithmetic processing section 23b. In this way, when the start button 37a is pushed after a plurality of operating condition settings are completed, the motor-operated microscope is continuously operated on the basis of the operating conditions enumerated in the produced journal file. By doing so, the operation of the screen becomes simpler and a large number of examinations can be carried out more efficiently and rapidly.
As will be evident from the above description, the present invention is useful in the fields of medical treatment, medical science, and biology in which the microplate is used through the motor-operated microscope to observe and/or measure living specimens, such as cells.
