Abstract:
1. 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; wherein the controller sets the light quantity distribution of the light to be incident on the surface of the specimen based on a luminance distribution in a preliminary image obtained by imaging the well by the imager under a predetermined standard light quantity distribution; and wherein the controller sets a larger incident light quantity for a position with lower luminance in a background image obtained by removing high frequency components higher than a predetermined spatial frequency from the preliminary image.
