Microscope system
A microscope system including an imaging portion, an image-acquisition portion that captures an image of a specimen formed by the imaging portion, a background identifying portion that identifies a background region other than a region containing the specimen in the image acquired by the image-acquisition portion, calibration-data generating portions that generate calibration data for correcting shading contained in the image on the basis of a luminance distribution of the background region, and a shading correcting portion that corrects the luminance of the image by using the calibration data.
1. A microscope system comprising:
an objective lens that forms an image of a specimen;
an image sensor that captures the image of the specimen formed by the objective lens; and
a processor comprising hardware, the processor being configured to:
identify a background region other than a region containing the specimen in the image acquired by the image sensor;
generate calibration data for correcting shading contained in the image on the basis of a luminance distribution of the identified background region; and
correct a luminance of the image by using the generated calibration data,
wherein the generating of the calibration data comprises:
estimating a luminance distribution of an entire region of the image on the basis of the luminance distribution of the identified background region,
calculating correction values for individual pixels of the image so that the estimated luminance distribution becomes uniform, and
generating the calibration data constituted of the calculated correction values.
2. The microscope system according to claim 1 , wherein:
the processor is further configured to allow an operator to specify at least one location in the background region in the image acquired by the image sensor,
wherein the identification of the background region comprises calculating a feature quantity of the specified location and identifies the background region in the image on the basis of the calculated feature quantity.
3. A microscope system comprising:
an objective lens that forms an image of a specimen;
an image sensor that captures the image of the specimen formed by the objective lens; and
a processor comprising hardware, the processor being configured to:
identify a background region other than a region containing the specimen in the image acquired by the image sensor;
generate calibration data for correcting shading contained in the image on the basis of a luminance distribution of the identified background region;
correct a luminance of the image by using the generated calibration data;
allow an operator to input an observation method;
store the observation method in association with a background identifying condition which a feature quantity of the background region satisfies, and
identify, in the image, a region that satisfies the background identifying condition as the background region.
