摘要：

PROBLEM TO BE SOLVED: To dispense with a dedicated signal processing means and to have simple structure when observing an object with a near-infrared light and generating a color still image.

SOLUTION: This fundus camera includes a near-infrared light generation means for observing an object with a near-infrared light, a visible light generation means for capturing an image with a visible light, an observation/imaging optical system receiving a reflected light from the fundus oculi and focusing a fundus image, a capturing means having three color filters of R, B and G disposed into a mosaic shape in front of respective pixels and capturing a fundus image, and a computing means calculating virtual pixel values of a tricolor image from adjoining pixel values and generating color image data. The color filter R is defined as a color filter transmitting the near-infrared light and the number of the filters R is defined to be more than the numbers of the color filters B and G.
