SAMPLE OBSERVATION APPARATUS AND METHOD FOR GENERATING OBSERVATION IMAGE OF SAMPLE
First Claim
1. A sample observation apparatus comprising:
- a storage section that stores information about an S/N ratio required in a raw image for generating a super-resolution image;
a number-of-image-data-sets calculator that calculates a number of image data sets to be added together for generating the raw image based on the S/N-ratio information stored in the storage section and a predetermined image acquisition condition;
an image-data acquisition section that acquires the image data by detecting light from a sample with the predetermined image acquisition condition;
a controller that causes the image-data acquisition section to acquire multiple sets of the image data of the same region of the sample by making the image-data acquisition section repeatedly detect light from the same region based on the number calculated by the number-of-image-data-sets calculator; and
a raw-image generator that adds together the multiple sets of image data of the same region acquired by the image-data acquisition section so as to generate the raw image.

Abstract
A good super-resolution image can be generated, while eliminating a troublesome task necessary for generating a raw image. Provided is a sample observation apparatus including a memory, which stores a first number of photoelectrons required in a raw image for generating a super-resolution image, and a main controller, which calculates the number of image data sets to be added together for generating the raw image based on the first number of photoelectrons stored in the memory and a predetermined image acquisition condition, which acquires multiple sets of image data of the same region of a sample by repeatedly detecting light from the same region based on the calculated number of image data sets, and which generates the raw image by adding together the acquired multiple sets of image data of the same region.

4. A sample observation apparatus comprising:
-
an image-data acquisition section that acquires image data by detecting light from a sample; a storage section that stores first S/N-ratio information required in a raw image for generating a super-resolution image; an S/N-ratio information calculator that calculates second S/N-ratio information to be acquired in multiple sets of the image data to be added together for generating the raw image based on the first S/N-ratio information stored in the storage section and a predetermined image acquisition time; a condition setting section that sets an image acquisition condition for acquiring the image data that satisfies the second S/N-ratio information calculated by the S/N-ratio information calculator; a controller that causes the image-data acquisition section to acquire multiple sets of image data of the same region of the sample by making the image-data acquisition section repeatedly detect light from the same region within the predetermined image acquisition time based on the image acquisition condition set by the condition setting section; and a raw-image generator that adds together the multiple sets of image data of the same region acquired by the image-data acquisition section so as to generate the raw image. - View Dependent Claims (5, 6, 7)

8. A method for generating an observation image of a sample, the method causing a controller to perform a process including executing control for causing an image-data acquisition section, which acquires image data by detecting light from the sample, to repeatedly acquire image data of the same region of the sample multiple times, and generating a raw image for creating a super-resolution image of the sample by adding together multiple sets of the image data of the same region repeatedly acquired by the image-data acquisition section as a result of the control, the method comprising:
-
causing the controller to store in advance information related to an S/N ratio that the raw image should have; causing the controller to execute control for determining the number of the image data sets to be added together for generating the raw image based on a preset image acquisition condition for the image-data acquisition section and the stored information related to the S/N ratio and repeatedly acquiring the image data of the same region in accordance with the determined number, or control for determining information related to an S/N ratio that the image data acquired by the image-data acquisition section should have based on a preset image acquisition time and the stored information related to the S/N ratio and making the image-data acquisition section repeatedly acquire the image data of the same region within the image acquisition time in a state where an image acquisition condition for acquiring the image data, which satisfies the determined information related to the S/N ratio, is set in the image-data acquisition section; and causing the controller to execute a process for generating the raw image by adding together multiple sets of the image data of the same region acquired by the image-data acquisition section as a result of the control.
