  • Publication number: 20190355097
    Abstract: There is provided an apparatus and a method that perform a process of improving the quality of a low-quality image such as a far-infrared image. The apparatus includes an image correction unit that repeatedly performs an image correction process using a plurality of processing units in at least two stages. The image correction unit inputs a low-quality image to be corrected and a high-quality image which is a reference image. Each of the processing units in each stage performs a correction process for the low-quality image, using a class correspondence correction coefficient corresponding to a feature amount extracted from a degraded image of the high-quality image. A processing unit in a previous stage performs the correction process, using a class correspondence correction coefficient corresponding to a feature amount extracted from an image which has a higher degradation level than that in a processing unit in a subsequent stage.

  • Patent number: 10352862
    Abstract: In a Raman spectroscopic microscope, a spatial resolution that exceeds the diffraction limit of light is achieved. A diffraction grating diffracts laser light emitted from a light source and thereby generates diffracted light. A spectroscope acquires a spectrum of incident light and a spatial distribution of light intensities of the spectrum. An optical system applies interference light formed by +1st order diffracted light and ?1st order diffracted light generated in the diffraction grating to an object to be observed as linear illumination light and guides a Raman scattered light generated by the application of the linear illumination light to the object to be observed to the spectroscope, the linear illumination light having its longitudinal direction in a first direction. A control unit controls the optical system and thereby scans the object to be observed by the linear illumination light in a second direction.
