Abstract: An observation apparatus includes a stage on which a sample is placed, image capturing device for capturing an image of the sample placed on the stage, velocity calculation unit for calculating a velocity of the stage, display unit for displaying the image of the sample, and a control unit for switching an operating mode, on the basis of the velocity of the stage, between a first operating mode for causing the display unit to display an image, which has a dynamic range wider than original images and is generated by merging the plurality of original images that the image capturing device obtains by capturing images of the sample under a plurality of different image capturing conditions, and a second operating mode for causing the display unit to display an original image or an image obtained by processing the original image.

Abstract: An image-processing device is provided with: a pattern-matching portion that performs pattern matching between a first image and a second image acquired before the first image and that outputs a motion vector between the images and an evaluation value that indicates the accuracy of the motion vector; a recursive noise-reduction portion that outputs a noise reduction image, which is the first image to which noise reduction has been applied, and that performs noise reduction in which an image based on the first image and an image based on the noise reduction image formed in the past are mixed in accordance with a predetermined recursion amount; and a controlling portion that controls a recursion amount in the recursive noise-reduction portion on the basis of the motion vector and the evaluation value output by the pattern-matching portion and a gain that is applied to the first image to adjust a brightness thereof.

Abstract: An image processing apparatus includes: a normalization unit that generates a plurality of normalized images by correcting, based on different imaging conditions, brightness of a plurality of images at different brightness obtained by imaging a same subject with the different imaging conditions; and an image combining unit that generates a combined image by combining the plurality of normalized images. When the normalized image corresponding to a reference image that is a brightest image among the plurality of images is defined as a reference normalized image, the image combining unit combines the reference normalized image and a non-reference normalized image that is the normalized image other than the reference normalized image to bring gradation of pixel of the combined image close to gradation of pixel of the reference normalized image if the gradation of pixel of the combined image is smaller than the gradation of pixel of the reference normalized image.
