An information processing apparatus, comprising: a housing having formed on the upper surface thereof a guide groove that is rounded and so formed as to model after a finger, and the guide groove has arranged at the bottom around the leading edge thereof an image pickup opening; a pair of near infrared light sources (16A and 16B) each of which emits a near infrared light as a light to pickup an image of a blood vessel, which are so arranged as to be in parallel with the width direction of the guide groove to sandwich the image pickup opening and a pair of visible light sources (17A and 17B) each of which emits a visible light as a light to pickup an image of a finger print, which are so arranged as to be in parallel with the longitudinal direction of the guide groove to sandwich the image pickup opening; filter array having arranged therein a plurality of pixel filters each of which forms a unit to transmit a light of a wavelength corresponding to a predetermined color configured to color-disperse the respective lights coming from the living body; separation means configured to separate a plurality of image components corresponding to the respective lights from an image pickup signal output as a result of a concurrent image pickup by an image pickup element for the respective lights dispersed by the dispersion means; signal processing means configured to carry out processing corresponding to the respective image components separated by the separation means; an image pickup unit which receives light through the image pickup opening; a transparent opening cover arranged in the image pickup opening; and a polarization plate that has the polarization axis parallel with the longitudinal direction of the guide groove, wherein the opening cover, the polarization plate, and the filter array are arranged sequentially and the polarization plate and the filter array are arranged in the image pickup unit. a housing having formed on the upper surface thereof a guide groove that is rounded and so formed as to model after a finger, and the guide groove has arranged at the bottom around the leading edge thereof an image pickup opening; a pair of near infrared light sources (16A and 16B) each of which emits a near infrared light as a light to pickup an image of a blood vessel, which are so arranged as to be in parallel with the width direction of the guide groove to sandwich the image pickup opening and a pair of visible light sources (17A and 17B) each of which emits a visible light as a light to pickup an image of a finger print, which are so arranged as to be in parallel with the longitudinal direction of the guide groove to sandwich the image pickup opening; filter array having arranged therein a plurality of pixel filters each of which forms a unit to transmit a light of a wavelength corresponding to a predetermined color configured to color-disperse the respective lights coming from the living body; separation means configured to separate a plurality of image components corresponding to the respective lights from an image pickup signal output as a result of a concurrent image pickup by an image pickup element for the respective lights dispersed by the dispersion means; signal processing means configured to carry out processing corresponding to the respective image components separated by the separation means; an image pickup unit which receives light through the image pickup opening; a transparent opening cover arranged in the image pickup opening; and a polarization plate that has the polarization axis parallel with the longitudinal direction of the guide groove, wherein the opening cover, the polarization plate, and the filter array are arranged sequentially and the polarization plate and the filter array are arranged in the image pickup unit.
