A first resin plate (65A) includes a phthalocyanine-based pigment as an organic fluorescent material (66) and is used for shading correction in a case in which infrared excitation light with a center wavelength of 770 nm to 800 nm. A second resin plate (65B) includes an anthraquinone-based pigment as the organic fluorescent material (66) and is used for shading correction in a case in which red excitation light with a center wavelength of 650 nm to 690 nm. An acquisition unit (90) acquires a reference image (86) obtained by irradiating the resin plates (65A, 65B) with the infrared excitation light and the red excitation light, respectively. A correction unit (96) performs shading correction for a fluorescence image on the basis of the reference image (86).
第一块
树脂板 (65A) 包括
酞菁基
颜料作为有机荧光材料 (66),在中心波长为 770 纳米至 800 纳米的红外激发光的情况下用于阴影校正。第二块
树脂板 (65B) 包括
蒽醌基
颜料作为有机荧光材料 (66),在中心波长为 650 纳米至 690 纳米的红色激发光情况下用于阴影校正。采集单元(90)通过分别用红外激发光和红色激发光照射
