An image processing device has an image input part to which a frame image of an imaging area taken with an infrared camera is input, a background model storage part in which a background model is stored with respect to each pixel of the frame image input to the image input part, a frequency of a pixel value of the pixel being modeled in the background model, a background difference image generator that determines whether each pixel of the frame image input to the image input part is a foreground pixel or a background pixel using the background model of the pixel, which is stored in the background model storage part, and generates a background difference image, and a threshold setting part.

In a waveguideincluding a substrate, a lower clad, an upper clad, and a core, the outline of a cross section perpendicular to the light propagating direction of the coresurrounded by the lower cladhas a shape curved with respect to the center of the cross section. The separation in the waveguide is thereby prevented, and the reliability of the optical property is enhanced.

Waveguide, waveguide module, optical transmission device, and method of manufacturing waveguide

A method of manufacturing a film waveguide includes supplying a precursor consisting of monomer or oligomer of an elastomer having a flexural modulus after curing smaller than or equal to 1,000 MPa to a substrate; pressing a stamper on the precursor of the elastomer, applying pressure to the precursor of the elastomer by the stamper and thinning a film thickness of the precursor of the elastomer; forming a lower clad layer by curing the precursor of the elastomer; forming a core on the lower clad layer; and forming an upper clad layer on the lower clad layer and the core. A film waveguide has at least one of a lower clad layer or an upper clad layer formed by an elastomer having a flexural modulus smaller than or equal to 1,000 MPa. A sum of film thicknesses of the clad layers is less than or equal to 300 mm.
