US 2013/0258076 A1 · IMAGING APPARATUS AND IMAGING METHOD

Abstract

A preliminary image is obtained by irradiating illumination light, whose light quantity distribution is set at a standard state, to a specimen obtained by injecting fluid into a well from an illuminator capable of arbitrarily setting the light quantity distribution, for example, by a liquid crystal shutter, and a luminance distribution of the preliminary image is detected. As a result, luminance nonuniformity in the preliminary image is canceled by performing imaging with a light quantity distribution of illumination light to be incident on the well set such that an incident light amount is larger in a part with lower luminance.

Dependent claims

An imaging apparatus, comprising:

a holder that holds a specimen holding plate substantially in a horizontal state, the specimen holding plate being formed with a well capable of holding liquid;
a light illuminator that irradiates light from above the specimen holding plate held by the holder to a surface of a specimen obtained by injecting fluid into the well;
a controller that controls a light quantity distribution of light to be incident on the surface of the specimen from the light illuminator based on a luminance distribution preliminarily measured at the well with the fluid;
and
an imager for obtaining an image of the specimen by imaging the specimen under light illumination at the light quantity distribution set by the controller.
