Abstract
An image generation device includes a first color signal generation unit that generates three or more types of first color signals Rl, Gl, and Bl by combining two or more types of near-infrared light signals SIR1 and SIR2 with three or more types of visible light signals SR, SG, and SB in arbitrary proportions. The visible light signals SR, SG, and SB are outputted from a solid-state imaging element, and the near-infrared light signals SIR1 and SIR2 are acquired simultaneously with the visible light signals SR, SG, and SB. The near-infrared light signals SIR1 and SIR2 are a signal based on near-infrared light and a signal based on near-infrared light. The first color signal generation unit 1 changes combining proportions of the visible light signals SR, SG, and SB and the near-infrared light signals SIR1 and SIR2 according to quality and/or strengths of each light signal.
