A vehicle travel assistance apparatus includes a traveling environment information acquiring unit, a preceding vehicle recognizing unit, a vehicle shadow detector, a front vehicle shadow determining unit, and a second preceding vehicle estimating unit. The vehicle shadow detector detects a vehicle shadow of a train of vehicles including a first vehicle shadow of a first preceding vehicle recognized by the preceding vehicle recognizing unit and a front vehicle shadow of a front vehicle traveling in front of the first preceding vehicle based on a brightness difference from a road surface. When the front vehicle shadow determining unit determines that the front vehicle shadow separating from the first vehicle shadow is identified from the vehicle shadow, the second preceding vehicle estimating unit estimates a position of a second preceding vehicle belonging to the train of the vehicles including the first preceding vehicle based on the front vehicle shadow.

In an analyzer, an image processing unit performs processing of: dividing a measurement image into a plurality of partial measurement images, and dividing a reference image into a plurality of partial reference images; calculating a positional deviation amount of each of the partial measurement images relative to a corresponding partial reference image among the partial reference images; determining whether the positional deviation amount is a threshold or less; and correcting positional deviation of the measurement image based on the positional deviation amounts of the plurality of partial measurement images when the image processing unit has determined that the positional deviation amount is not the threshold or less.

Analyzer and image processing method

An analyzer includes a wavelength-dispersive X-ray spectrometer and a control unit that controls the wavelength-dispersive X-ray spectrometer, the control unit performing: processing of acquiring an analysis result of preparatory analysis performed on a specimen to be analyzed; processing of setting spectroscopic conditions for WDS analysis using the wavelength-dispersive X-ray spectrometer based on the analysis result of the preparatory analysis; and processing of performing the WDS analysis on the specimen to be analyzed under the set spectroscopic conditions.

Analyzer

An X-ray analyzer includes: a specimen stage; a spectrometer having a spectroscopic element and an X-ray detector; a temperature measuring unit including at least one of a first temperature sensor for measuring a temperature of the specimen stage and a second temperature sensor for measuring a temperature of the spectrometer; a storage unit which stores calibration data of the spectrometer, and a previous measurement result by the temperature measuring unit at the time of execution of the calibration of the spectrometer; and a notifying unit which acquires a measurement result by the temperature measuring unit, calculates a temperature variation amount of the acquired measurement result with respect to the previous measurement result stored in the storage unit, and notifies that calibration is needed, based on the temperature variation amount.
