摘要： In a pupil detection apparatus, based on a calculated value of red-eye occurrence intensity that is relative brightness of brightness within a first pupil image detected by a pupil detector with respect to brightness of a peripheral image outside the first pupil image, and a correlation characteristic of red-eye occurrence intensity and a pupil detection accuracy value, a switching selector selectively outputs a detection result of the first pupil image or a detection result of a second pupil image detected by a pupil detector. The pupil detection apparatus has a first imaging pair including an imager and an illuminator separated by a separation distance, and a second imaging pair whose separation distance is greater than that of the first imaging pair.

摘要： Disclosed is a method for producing a cyclic olefin compound having two or more cyclohexene rings per molecule via intramolecular dehydration of an alicyclic alcohol having two or more hydroxylated cyclohexane rings per molecule. The method includes the step (i) of heating the alicyclic alcohol at a temperature of 130° C. to 230° C. and a pressure greater than 20 Torr in an organic solvent in the presence of a dehydration catalyst, to carry out dehydration of the alicyclic alcohol while distilling off by-product water, which dehydration catalyst is liquid or soluble in a liquid reaction mixture under the reaction conditions; and the subsequent step (ii) of heating the resulting reaction mixture at a temperature of 50° C. to 220° C. and a pressure of 200 Torr or less to recover the cyclic olefin compound as a distillate. According to the method, side reactions such as isomerization are suppressed, and high-purity cyclic olefin compounds with less impurities can be simply and efficiently obtained in high yields.
