Abstract
Infrared light emitted by a fluorescent material is weak. When an infrared image obtained by this fluorescent material is superposed and displayed on a visible-light image, the infrared image is made clear. A signal <IR> of an IR pixel having selective sensitivity to infrared light is subtracted from RGB pixel signals <R>, <B>, and <G> of a solid-state image sensor by adders (), and signals R, G, and Bthat correspond to the R, G, and B components of incident light within <R>, <G>, and <B> are separated and extracted. <IR> is multiplied by each of the gains κ, κ, and κto enhance the IR component by multipliers (), and each is synthesized with R, G, and Bby adders (). κ, κ, and κare set so that the infrared image displayed on the visible-light image by the synthesized IR component is enhanced and displayed in a hue that can be distinguished from the color white or another visible-light image.
