  • Patent number: 10282622
    Abstract: A system detects a candidate for an object which intrudes based on images of a visible light camera and a far-infrared camera that monitor the sea, further derives a size, a velocity, an intrusion direction, and linearity, and identifies the object to some extent. Also, the system distinguishes between a boat, a human, and a floating matter based on the luminances or the like in a far-infrared image. In addition, the system observes the periodicity of normal waves on the sea surface at a location without any object by performing the Fourier transform on the image. The accuracy of identification of an object is improved based on the correlation between the motion of waves in a normal state and the motion of the object.

  • Patent number: 9960308
    Abstract: A number of micro-sized rectangular dot-like n-type semiconductor regions 121 are created in a p-type semiconductor region which is a base body 11. Contact parts 14, each of which is in contact with one n-type semiconductor region 121 and almost entirely covers the same region, are mutually connected by a wire part 15 as a common cathode terminal. The n-type semiconductor regions 121 receives no light; their function is to collect carriers generated within and outside the surrounding depletion layers. Appropriate setting of the spacing of the n-type semiconductor regions 121 enables efficient collection of the carriers generated in the p-type semiconductor region while improving the SN ratio of the photo-detection signal by a noise-reduction effect due to a decrease in the p-n junction capacitance. Carriers originating from light of shorter wavelengths are barely reflected in the photo-detection signal. Thus, unfavorable influences of the shorter wavelengths of light are eliminated.
