    Abstract: The distal end of an inserted portion, having a simple structure, is reduced in diameter, loss of light incident from a body cavity is reduced, and light from two different directions is observed simultaneously and in a separated fashion. Provided is an endoscope apparatus (1) including an inserted portion (2) to be inserted inside a body cavity; a first dichroic mirror (8), disposed in a distal end portion of the inserted portion (2), that transmits light (L4) in a first wavelength band, which is incident from a longitudinal axial direction and that deflects light (L2) in a second wavelength band, which is incident from a radial direction, in the longitudinal axial direction, thereby multiplexing it with the light (L4) in the first wavelength band; a second dichroic mirror (13) that splits the light (L2, L4) multiplexed by the first dichroic mirror (8) into each wavelength band; and two image-acquisition units (16, 17) that respectively acquire the light (L2, L4) in the first and second wavelength bands split by the second dichroic mirror (13).

    Abstract: A pressure damper has a main body with a recessed section for storing liquid. A thin film is mounted to the main body so as to hermetically seal the recessed section. A reference member is arranged in the recessed section of the main body and is configured to be brought into contact with or separated from the thin film. A detecting unit is configured to detect, without contacting the reference member, a displacement of the reference member due to a pressure change of the liquid stored in the recessed portion of the main body.

    Abstract: A fluoroscopy apparatus includes a light-source device that generates illumination light and excitation light; a fluorescence-image generating unit that generates a fluorescence image based on irradiation with the excitation light; a white-light-image generating unit that generates a white-light image based on irradiation with the illumination light; a fluorescence-image correcting unit that generates a corrected fluorescence image by dividing the signal strengths of pixels in the fluorescence image by the signal strengths of pixels in the white-light image; a characteristic-value acquiring unit that extracts the characteristic value of the corrected fluorescence image; a threshold setting unit that sets a threshold for determining a region of interest in the corrected fluorescence image using a history of characteristic values extracted by the characteristic-value acquiring unit; and a pseudo-color-image generating unit that discriminates between a region of interest and another region in the corrected fluorescence image on the basis of the threshold.
