Abstract: A magnified observation apparatus includes an illuminator, a feature quantity calculator, and an illumination controller. The illumination controller selectively performs first and second sequences. In the first sequence, the illuminator is operated in the first lighting pattern, and a display is operated to display a live image of the observation object that is irradiated with the first lighting pattern by a display controller. In the second sequence, the illuminator is operated in the second lighting pattern as at least one of the different illumination directions that is selected based on the feature quantities of the image data, which are calculated correspondingly to the different illumination directions by the feature quantity calculator, and the display is operated to display by the display controller an image of the observation object that is captured when the observation object is irradiated with the second lighting pattern.

Abstract: Adjustment of test parameters in a colony counting device is facilitated. A colony counting device displays a plurality of colony detection results, obtained by applying different colony detection parameters to an image of a test individual, in a comparable manner on a display section, selects one colony detection result from among the plurality of colony detection results according to an operation of a user, and applies the colony detection parameter used to obtain the selected one colony detection result to the image of the test individual to count the number of colonies included in the image of the test individual.

Abstract: A magnified observation apparatus includes an FOV changer, an in-focus degree evaluator, and a focus sequence executor. The in-focus degree evaluator calculates in-focus degree feature quantities, which represent in-focus degrees of image data corresponding to images to be displayed by a display controller on a display. The focus sequence executor executes an FOV-moving focus sequence in which a focusing device adjusts a relative distance between a focus position of the objective lens and an observation object in accordance with in-focus degree feature quantities of image data that are successively calculated by the in-focus degree evaluator corresponding to images of the observation object that are captured during movement of an observation FOV by the FOV changer so that a live image of the observation object is displayed on the display based on image data that is obtained during the movement of an observation FOV by the display controller.

Abstract: Counting accuracy of colonies is improved. A colony counting device captures a test individual to generate an image of the test individual, registers the image of the test individual in an initial state as a reference image, identifies a residue included in the reference image and identifies a position of the residue in a test image corresponding to the residue included in the reference image based on a displacement of each of two or more common characteristic portions between the reference image and the test image that is an image of the test individual after culturing, and counts the number of colonies while excluding the residue from a count as a colony based on the position of the residue.

Abstract: To mitigate burden on a user regarding counting colonies. A colony counting device stores a count table including a cell to which a count result of each of a plurality of test individuals is input, displays the stored count table on a display device, identifies a target cell to which the count result is input from among a plurality of the cells included in the count table, acquires a test image that is an image of the test individual, acquires the test image according to a counting instruction, counts colonies included in the test individual based on the test image, and reflects the number of the colonies counted on the target cell.

Abstract: An emitting section of a light projecting section is provided to surround an optical axis of an objective lens of a lens unit. The optical axis of the emitting section is substantially the same as the optical axis of the objective lens. Ring illumination is irradiated on the observation target from the emitting section and light from the observation target is received by an imaging section via the objective lens, whereby first original image data is generated. Directional illumination is irradiated on the observation target from the emitting section and the light from the observation target is received by the imaging section via the objective lens, whereby second original image data is generated. Image data for display indicating an image of the observation target that should be obtained when it is assumed that light in a specific emitting direction is irradiated on the observation target is generated.

Abstract: Provided is an image processing apparatus and an image processing program which are capable of selectively and readily acquiring a geometrical physical quantity of a desired measuring portion. An object image is displayed based on object image data, and a measuring portion designating image corresponding to a specific portion of the object image is displayed based on designating image data. By operation of an operation part by a user, the displayed measuring portion designating image is moved relatively to the object image. When the measuring portion designating image is moved to a specific portion of the object image, a geometrical physical quantity of a measuring portion of the measuring object, previously set so as to correspond to that specific portion, is measured.
