A microscope system includes: a stage on which a specimen is configured to be placed; an objective lens disposed so as to face the stage; an oblique illumination unit having a plurality of light emitting units arranged annularly around or outside the objective lens, the oblique illumination unit being configured to emit oblique illumination light for irradiating the specimen; an input unit configured to receive an instruction signal that instructs a rotation mode for changing, at regular intervals, a light emitting area where one or more light emitting units of the plurality of light emitting units are caused to emit the oblique illumination light; and an illumination controller configured to change the light emitting area at the regular intervals by controlling light emitting timing of each of the plurality of light emitting units when the input unit receives the instruction signal.

Microscope system and illumination operation device

A focusing device that includes a differential interference prism used in differential interference observation in a focusing detection optical system includes: a light source that emits light with which a measurement surface of an observation sample is irradiated; a photo detection unit that detects light from the measurement surface; a focusing detection unit that detects an error signal near a focusing point of the measurement surface on the basis of an output signal from the photo detection unit; and a condition changing unit that changes an acquisition condition of the error signal.

Focusing device including a differential interference prism

A microscope system and an autofocus method capture a subject at a specified time interval through an optical image forming system while relatively moving a stage loaded with the subject and the optical image forming system of the microscope; calculate a contrast value indicating a high and low contrast of a captured observation image; detect a maximum contrast image whose calculated contrast value is maximum in a plurality of performed observation images; detect the relative position of the stage and the optical image forming system; perform a correcting process of moving the detected relative position corresponding to the detected maximum contrast image by a specified value in a direction opposite the direction of the relative movement; and bring focus using the corrected relative position as a focal point.

Microscope system and autofocus method

A microscope system includes: an illumination unit; a light control direction unit specifying quantity of light output from the illumination unit; a storage unit storing voltage-related information in which a direction value specified by the light control direction unit and a voltage value to be applied to the illumination unit are associated with each other and are set, the direction value being in an entire range that can be specified by the light control direction unit under each observation condition, the voltage value corresponding to the direction value; a light quantity control unit controlling the quantity of the emitted light; and a control unit acquiring the voltage value corresponding to the specified direction value from the voltage-related information corresponding to the observation condition, and allowing the light quantity control unit to control the quantity of light based on the acquired voltage value.

Microscope system and method for controlling it

A network system including a plurality of mobile devices is provided. The plurality of mobile devices each have a sensor function and a wireless communication function, the mobile devices communicating sensor information about a target with one another and tracking the target; a target searching section configured to obtain sensor information while the plurality of the mobile devices move and for reporting the sensor information among the mobile devices by wireless communication; a target focusing section configured to, in response to one of the mobile devices detecting a target, focus a sensor on the target in cooperation with mobile devices adjacent to the mobile device detecting the target; and a target surrounding section configured to surround the target by using a plurality of mobile devices that focus their sensors on the same target.

Network system, mobile device, method of controlling same, and computer program

A network system, radio communication device, radio communication method, and computer program for same are provided. The present invention enables formation of a network topology with sensor nodes each having a traveling function and operating in the self-directive and dispersive state without using positional information. Each sensor nodes periodically transmits a HELLO message to neighboring nodes to exchange information therewith. In an area where the node density is high, the nodes are set in the Expand state and in the Bridge state. A node in the Expand state shifts to the Stay state when the node can be connected to only one neighboring node to becomes a component of the topology. A node in the Bridge state shifts to the Stay state together with neighboring nodes each having hidden terminals not less than a prespecified number to become a component of the topology.
