  • Publication number: 20200303619
    Abstract: The present invention addresses the problem of providing a bimorph-type piezoelectric film that is less susceptible to the influence of pyroelectric noise resulting from temperature changes, and that makes it possible to provide a pressure-sensitive sensor or the like. The present invention provides a bimorph-type piezoelectric film comprising a first pyroelectric film having piezoelectric anisotropy in an in-plane direction, and a second pyroelectric film having piezoelectric anisotropy in an in-plane direction, the first pyroelectric film and the second pyroelectric film being disposed in such a manner that their surfaces on which electric charges of the same polarity are generated by a temperature increase are each outward-facing.

  • Patent number: 10733734
    Abstract: An image analysis apparatus includes a processor including hardware. The processor extracts parts from each of a first image and a second image acquired after the first image, each of the extracted parts including an annular peripheral portion and a central portion having a color different from a color of the peripheral portion. The processor also sets the central portion as the analysis object region and calculates a brightness decrease degree of the analysis object region in the second image relative to the analysis object region in the first image.

  • Publication number: 20190122392
    Abstract: An image analyzing apparatus includes an image input portion, an image processor, a distribution characteristic value calculator, a recording portion, and a comparison information output portion. The image input portion inputs an endoscopic image. The image processor generates a brightness-corrected image. The endoscopic image is corrected to the brightness-corrected image wherein the brightness-corrected image includes a brightness distribution that being substantially uniform. The distribution characteristic value calculator extracts at least one of a red color component, a green color component, and a blue color component in the brightness-corrected image and determines a first distribution characteristic value of the extracted color component. The recording portion records information including a plurality of second distribution characteristic values.
