Title:
蛍光観察装置
Document Type and Number:
Japanese Patent JP5669416
Kind Code:
B2
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.
