Abstract: The image inspection apparatus includes an image score calculator and an imaging condition specifier. The image score calculator calculates scores of images, which are produced under different imaging conditions. The imaging condition specifier receives, when two or more thumbnails corresponding to two or more of the images that have a higher score are displayed on the display, selection of one from the two or more thumbnails to specify a set of imaging conditions corresponding to the thumbnail selected. The different imaging conditions include a single-shot set of conditions under which a single-shot image is produced, and a composition series of sets of conditions under which images are captured to produce a composite image from the images. The display shows a reference information display area that indicates reference information representing the single-shot set or composition series of sets in response to the displaying of the two or more thumbnails.

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: Provided is a level meter capable of correctly measuring a level of an object stored in a container. The level meter includes a distribution determination unit, an extraction unit, a candidate determination unit, and a display portion. The distribution determination unit determines the reception intensity distribution of the reflection signal with respect to the distance from the level meter based on the reception intensity of the reflection signal due to reflection of the measurement signal. The candidate determination unit extracts a plurality of combinations of the peak position and the peak intensity from the reception intensity distribution by the extraction unit, and determines the combinations as a plurality of peak candidates. The display portion displays a candidate confirmation screen including the measurement value corresponding to each of the plurality of peak candidates and the reception intensity scale related to the reception intensity.

Abstract: Wiring work without requiring a safety PLC is simplified even when a plurality of safety switches having a lock function are arranged. The plurality of safety switches are cascade-connected to a wiring unit. The wiring unit supplies power received via the power input unit (a VCC terminal or a GND terminal) to the plurality of safety switches. The wiring unit performs through-output of an OSSD input received from the most downstream safety switch to the outside of the wiring unit. The wiring unit outputs upstream-facing communication data COM (a lock input or the like) based on a lock instruction (LOCK). The wiring unit receives downstream-facing communication data COM (such as bundle data of AUX outputs) and outputs the communication data COM as individual AUX outputs.

Abstract: An image processing device includes an imaging unit generating an inspection target image, a storage unit storing a reference image obtained by capturing an inspection object in advance, and a calculation unit specifying a positional relationship between an inspection object included in the inspection target image generated during operation and the inspection object included in the reference image, and calculates a generation condition of the inspection target image during operation such that the inspection object included in the inspection target image generated during operation and the inspection object included in the reference image are at substantially the same position. The generation condition includes positional information of an output region in which the inspection object is able to be output at substantially the same position as the reference image. The imaging unit generates an inspection target image corresponding to the output region of the positional information during operation.
