Biological information is detected with high accuracy without restraining the living body of a subject. A biological information detection apparatus projects a first light source for projecting at least one first dot by a first light onto a living body and at least one second dot by a second light on the living body. A second light source, a plurality of first light detection cells for detecting the first light, and a plurality of second light detection cells for detecting the second light, wherein at least one first dot is projected An imaging system for generating and outputting a first image signal indicating a first image of the living body and a second image signal indicating a second image of the living body on which at least one second dot is projected; An arithmetic circuit that generates and outputs information related to a living body using the first image signal and the second image signal output from the imaging system, and the wavelength of the first light and the second light All wavelengths are 650 nm or more and 950 nm or less. Ri, the wavelength of the second light is longer than 50nm than the wavelength of the first light. [Selection] Figure 1A |
