Microscopy system, microscopy method, and computer-readable storage medium

1. A microscopy system comprising:

an imaging apparatus that captures an image of a subject through a microscopy optical system of a microscope and generates a subject image; and

a processor comprising hardware, the processor being configured to

set a capturing condition of the imaging apparatus, and

control the imaging apparatus based on the capturing condition, thereby to cause the imaging apparatus to capture an image of the subject;

wherein

the processor is further configured to

set a first capturing condition for first previous capturing to capture a previous image for generating a primary image of the subject, as the capturing condition of the imaging apparatus, the first previous capturing being sweep capturing that is capturing while changing a position of a focal plane with respect to the subject, such that brightness saturation does not occur in the previous image obtained during the sweep capturing, and

capture the primary image based on the previous image,

wherein

the processor is further configured to

set a second capturing condition for primary capturing to capture the primary image, as the capturing condition of the imaging apparatus, the primary capturing being sweep capturing that is capturing while changing a position of a focal plane with respect to the subject, based on the previous image captured during the first previous capturing, and

cause the imaging apparatus to capture the image of the subject in accordance with the second capturing condition for the primary capturing.

2. The microscopy system according to claim 1 , wherein the processor is further configured to generate the primary image based on the previous image.

3. The microscopy system according to claim 1 , wherein

the processor is further configured to

determine whether capturing the primary image by sweep capturing is to be executed in accordance with the primary image generated based on the previous image, and

set the second capturing condition for the primary image as the capturing condition of the imaging apparatus, when it is determined that the capturing of the primary image by the sweep capturing is to be executed.

4. The microscopy system according to claim 1 , wherein the processor is further configured to acquire an omnifocal image based on the primary image and blur information on the primary image.

5. The microscopy system according to claim 4 , wherein the blur information includes information generated by using a point spread function representing blur of the primary image in a capturing range of the sweep capturing.

6. The microscopy system according to claim 1 , wherein

the processor is further configure to

set a third capturing condition for second previous capturing that is conducted before the first previous capturing, the second previous capturing being still image capturing for capturing a still subject image at a capturing start position or a capturing end position in a capturing range of the sweep capturing,

set the third capturing condition for the second previous capturing thereby to acquire an exposure time of the still subject image, and

set the first capturing condition for the first previous capturing based on the exposure time obtained during the second previous capturing.

7. The microscopy system according to claim 1 , wherein the first capturing condition preventing the brightness saturation includes an exposure time for conducting the sweep capturing.

8. A microscopy method comprising:

setting a first capturing condition for previous capturing to generate a previous image for generating a primary image based on a subject, the previous capturing being sweep capturing that is capturing while changing a position of a focal plane with respect to the subject, such that brightness saturation does not occur in the previous image obtained during the sweep capturing;

causing an imaging apparatus to capture the previous image in accordance with the first capturing condition for the previous capturing set at the setting;

setting a second capturing condition for primary capturing to generate the primary image on the basis of the previous image captured through the previous capturing by the imaging apparatus, the primary capturing being sweep capturing that is capturing while changing the position of the focal plane with respect to the subject; and

causing the imaging apparatus to capture the primary image in accordance with the second capturing condition that has been set in the setting the second capturing condition.

9. A non-transitory computer-readable storage medium storing a microscopy program causing a computer to execute:

setting a first capturing condition for previous capturing to generate a previous image for generating a primary image based on a subject, the previous capturing being sweep capturing that is capturing while changing a position of a focal plane with respect to the subject, such that brightness saturation does not occur in the previous image obtained during the sweep capturing;

causing an imaging apparatus to capture the previous image in accordance with the first capturing condition for the previous capturing set at the setting;

setting a second capturing condition for primary capturing to generate the primary image on the basis of the previous image captured through the previous capturing by the imaging apparatus, the primary capturing being sweep capturing that is capturing while changing the position of the focal plane with respect to the subject; and

causing the imaging apparatus to capture the primary image in accordance with the second capturing condition that has been set in the setting the second capturing condition.
