- stage number designate a stage number and move to the stage base point. It is also possible to move directly to the pre-selected shooting point by operating the “Move to selected shooting Pt.” Button. Note that the X, ⁇ , and ⁇ coordinates are displayed in detail in the “shooting point setting” for the selected shooting point.
- the computer 5 After setting the shooting point in the "shooting point setting screen" as described above, when the setting screen is closed, the computer 5 displays the "cell observation system” screen on the display 4. indicate. Then, by selecting “observation settings” displayed on this “cell observation system” screen and selecting “observation conditions” (not shown) in the “observation settings”, an “observation condition input screen” (not shown) is displayed. Then, enter the shooting conditions for observation using Timelabs on the screen.
- Timelabs imaging is a function that automatically captures images at a predetermined time interval and records the captured microscope images in the memory 9 of the computer 5, and observes temporal changes in living cells. It is suitable for.
- this “observation condition input screen” it is possible to set a plurality of or a single shooting time for each “shooting point” set in the “shooting point setting screen”. .
- the stage movement time moving of the table 37
- shooting time and camera exposure time after shooting are affected.
- the setting shall be made taking into account the timelabs interval time.
- the computer 5 displays the "cell observation system” screen. Then, the computer 5 is controlled in accordance with the set shooting conditions, whereby the shooting at the set shooting point is performed at each set shooting time.
- the computer 5 captures the photographed microscope image, the photographing date (the photographing time), each temperature data (internal temperature, stage temperature) output from the incubator side control device C1 at that time, each gas Information on culture environment such as concentration data (CO gas concentration, O gas concentration) and correspondence
- the scale display is displayed in the same manner as the “image information at the current position” on the “shooting point setting screen”. make it possible to do. As a result, it is possible to confirm the approximate dimensions of the cells to be observed with a scale display without relying on guesses, even for stored microscopic images, and realize appropriate cell (cell culture) observations. It becomes possible.
- FIG. 1 Partial perspective of the culture observation apparatus constituting the culture observation system to which the present invention is applied. It is a front view.
- FIG. 5 is an electric block diagram of a control device constituting the culture observation system.
- FIG. 6 is a diagram showing a “shooting point setting” screen displayed on the display.
- FIG. 7 is a diagram showing a “coordinate movement amount setting” screen displayed on the display.
- FIG. 8 is a diagram showing a “shooting point setting” screen displayed on the display.
- FIG. 9 is a diagram showing a “shooting point setting” screen displayed on the display.
- FIG. 10 is a diagram showing a “cell observation system” screen displayed on the display.
- FIG. 11 is a diagram showing the relationship between the sample container and the sharpness.
