    摘要： A pupil detection device and a pupil detection method, which are capable of stably detecting the pupil by actively using information of cornea-reflected image even when most of the pupil is hidden by the cornea-reflected image. In pupil detection device (100), peripheral state evaluating section (105) sets a plurality of line segments having a reference point of a cornea-reflected image as one end and having a predetermined length, and calculates a luminance evaluation value based on luminance of each pixel in each line segment and reference luminance. Pupil center straight line calculation section (106) specifies a pupil center straight line passing through a center of a pupil image from among a plurality of line segments based on a luminance evaluation value. Pupil search section (107) detects a pupil image based on a luminance state around the pupil center straight line.

    摘要： Disclosed are an ambient light reflection determination apparatus and an ambient light reflection determination method enabling to determine reflection without using an edge and even in a case where luminance of a reflection generating part in eyeglasses is low. In a reflection determination apparatus (100), a luminance histogram calculation section (102) calculates a luminance histogram representing a luminance distribution of an eye area image, a difference calculation section (104) calculates a difference histogram by finding a difference between the two luminance histograms calculated from the two eye area images having different photographing timings, an evaluation value calculation section (105) calculates an evaluation value regarding reflection of ambient light based on the difference histogram and a weight in accordance with luminance, and a reflection determination section (107) determines the reflection of ambient light based on the calculated evaluation value.

    摘要： While an illumination optical system 2 is irradiating the surface of a contaminated standard wafer 110 with illumination light, this illumination light is scanned over the surface of the contaminated standard wafer 110, then detectors 31 to 34 of a detection optical system 3 each detect the light scattered from the surface of the contaminated standard wafer 110, next a predefined reference value in addition to detection results on the scattered light is used to calculate a compensation parameter “Comp” for detection sensitivity correction of photomultiplier tubes 331 to 334 of the detectors 31 to 34, and the compensation parameter “Comp” is separated into a time-varying deterioration parameter “P”, an optical characteristics parameter “Opt”, and a sensor characteristics parameter “Lr”, and correspondingly managed.This makes it easy to calibrate the detection sensitivity.
