Abstract: A cell counting device for counting the number of cells in a sample includes: an accommodation portion that accommodates, in a removable manner, at least a part of a holding member for holding the sample; and a display unit configured to display information including a result of counting of the number of cells. The display unit has a screen inclined with respect to a bottom of the cell counting device. The bottom is configured to be in contact with a placement surface on which the cell counting device is placed. The display unit is provided between the accommodation portion and the bottom.

Abstract: A microscope apparatus includes an image capturing unit, a recognition unit, a rotational shift angle calculation unit and a position reproduction unit. The rotational shift angle calculation unit calculates a rotational shift angle between a first pattern image recognized by the recognition unit from an image of the circular sample, which is obtained by the image capturing unit in a first period, and a second pattern image recognized by the recognition unit from an image of the circular sample, which is obtained by the image capturing unit in a second period later than the first period. The position reproduction unit corrects a rotational shift of the circular sample based on the rotational shift angle calculated by the rotational shift angle calculation unit, and reproduces a position of the circular sample in the first period.

Abstract: An image sensor captures an observation image formed on a light-receiving surface. An order adjustment unit makes the image sensor capture an original entire-area image being a picture of the observation image for an entire area of the light-receiving surface under a first exposure condition, and makes the image sensor capture a partial-area image being a picture of the observation image for only a partial area of the light-receiving surface under a second exposure condition. A synthesizing unit synthesizes the original entire-area image and the partial-area image to obtain an entire-area image having a wider dynamic range than the original entire-area image.
