Image processing device and fluoroscopy device

摘要

Employed is an image processing device including a fluorescence-image generating unit that images fluorescence generated at a subject irradiated with excitation light and generates a fluorescence image; a white-light-image generating unit that images white light returned from the subject irradiated with illumination light and generates a white-light image; a memory that converts the white-light image to a plurality of color signals constituting a color space; an image computing unit that corrects the plurality of color signals converted by the memory using at least one color signal among the plurality of the color signals and the fluorescence image; an image computing unit that generates a corrected image from the plurality of color signals corrected by the image computing unit; and an image combining unit that combines the fluorescence image generated by the fluorescence-image generating unit and the corrected image generated by the image computing unit.

主权项

1. An image processing device comprising hardware, the image processing device being configured to implement:
a fluorescence-image generating unit configured to image fluorescence generated at a subject irradiated with excitation light and generate a fluorescence image; a return-light-image generating unit configured to image return light returned from the subject irradiated with illumination light and generate a return-light image; a color converting unit configured to convert the return-light image generated by the return-light-image generating unit to a plurality of return-light image color signals constituting a color space; a color-signal correcting unit configured to correct the plurality of return-light image color signals converted by the color converting unit using both of: (a) at least one color signal among the plurality of return-light image color signals; and (b) the fluorescence image generated by the fluorescence-image generating unit; a corrected-image generating unit configured to generate a corrected return-light image from the plurality of return-light image color signals corrected by the color-signal correcting unit; and an image combining unit configured to combine the fluorescence image generated by the fluorescence-image generating unit and the corrected return-light image generated by the corrected-image generating unit; wherein the plurality of return-light image color signals comprise signals of R, G, and B components of the return-light image; and wherein the color-signal correcting unit multiplies results of dividing the fluorescence image generated by the fluorescence-image generating unit by at least one signal among the R, G, and B components of the return-light image with the signals of the R, G, and B components of the return-light image.
