  • Publication number: 20140228638
    Abstract: An electronic endoscope system is composed of an electronic endoscope, a light source apparatus, and a temperature converter. The electronic endoscope has a CMOS sensor in a distal portion of an insert section to be inserted into a patient's body cavity. Illumination light from the light source apparatus is applied to the body cavity through the distal portion. The temperature converter obtains an average pixel value of an optical black (OB) region out of an imaging signal from the CMOS sensor, and converts the average OB pixel value into a temperature of the CMOS sensor on a frame-by-frame basis with the use of data in a temperature conversion table. The table represents a relationship between the average OB pixel value and the temperature of the CMOS sensor. Light quantity of the illumination light is adjusted in accordance with the temperature of the CMOS sensor to prevent deterioration of image quality.

    Abstract: The pattern inspection apparatus includes: an irradiator irradiating a sample with an electron beam; an electron detector detecting an amount of electrons generated on the sample having a pattern formed thereon, by the irradiation of the electron beam; an image processor generating a SEM image of the pattern on the basis of the electron amount; and a controller acquiring defect position information on the pattern formed on the sample from an optical defect inspection device. The controller specifies a defect candidate pattern from the SEM image on the basis of the defect position information and judges whether a defect in the defect candidate pattern is to be transferred onto a wafer. The controller determines a view field of the SEM image on the basis of the defect position information and specifies the defect candidate pattern from image information on patterns displayed in the view field.
