Iris authentication apparatus with optical bandpass filter and adjustable fixed focus lens
First Claim
1. A photographing apparatus for authentication that photographs iris patterns of a recognized person for iris authentication and photographs a general object, comprising:
- a body case whose front side is open;
a camera module disposed inside the body case, and generating an iris pattern image by photographing the iris patterns while generating a general image by photographing the general object wherein the camera module comprises;
a housing;
a lens module where more than one lens is arrayed in a line, and moving in front/rear directions; and
a pickup device disposed at the back of the lens module, and converting an image incident through the lens module into an electric signal;
a band pass filter disposed in front of the camera module, wherein the band pass filter has a transmittance of 90% to 95% for beams having a wavelength of 750 nm to 1000 nm and a transmittance of 55% to 65% for beams having a wavelength of 400 nm to 750 nm, among beams incident on the lens module; and
an LED lamp disposed around a front side of the camera module, and irradiating infrared wavelength beams forward.

13. In a photographing module for iris authentication comprising a photographing apparatus for iris authentication that photographs iris patterns of a recognized person for the iris authentication and photographs a general object, and an image conversion module that converts an image of the iris patterns photographed by the photographing apparatus for iris authentication into a code,
wherein the photographing apparatus for iris authentication comprises: -
a camera module composed of a lens module that configures a focus lens having a fixed focal distance by arraying more than one lens in a line and that moves in front/rear directions, and a pickup device that converts an image incident through the lens module into an electric signal by being disposed on a rear side of the lens module, and generating an iris pattern image by photographing the iris patterns while generating a general image by photographing the general object, a band pass filter disposed in front of the camera module, wherein the band pass filter has a transmittance of 90% to 95% for beams having a wavelength of 750 nm to 1000 nm and a transmittance of 55% to 65% for beams having a wavelength of 400 nm to 750 nm among beams incident on the lens module; and an LED lamp that irradiates an infrared wavelength band of a beam for photographing the iris patterns forward, by being disposed around a front side of the camera module; and the image conversion module, comprising; a temporary memory for storing the iris pattern image; and an image processor for converting the iris pattern image into a code and generating the iris pattern code. - View Dependent Claims (14, 15, 16, 17)

18. A terminal having a photographing apparatus for authentication that photographs iris patterns of a recognized person and a general object, and authenticating the iris of the recognized person by photographing iris patterns of the recognized person to give a right to use and access to the recognized person, with the photographing apparatus for authentication, comprising:
-
the photographing apparatus for iris authentication that generates an iris pattern image by photographing the iris patterns of the recognized person and generates a general image by photographing the general object;
wherein the photographing apparatus for iris authentication comprises;a camera module composed of a lens module that configures a focus lens having a fixed focal distance by arraying more than one lens in a line and that moves in front/rear directions, and a pickup device that converts an image incident through the lens module into an electric signal by being disposed on a rear side of the lens module, and generating the iris pattern image by photographing the iris patterns while generating the general image by photographing the general object; a band pass filter disposed in front of the camera module, wherein the band pass filter has a transmittance of 90% to 95% for beams having a wavelength of 750 nm to 1000 nm and a transmittance of 55% to 65% for beams having a wavelength of 400 nm to 750 nm among beams incident on the lens module; and an LED lamp that irradiates an infrared wavelength band of a beam for photographing the iris patterns in a forward direction, by being disposed around a front side of the camera module; and an image conversion module for converting the iris pattern image photographed by the photographing apparatus for iris authentication into a code wherein the image conversion module comprises; a temporary memory for storing the iris pattern image; and an image processor for converting the iris pattern image into a code and generating the iris pattern code; and wherein the iris authentication of the recognized person is conducted by comparing the iris pattern code with an iris authentication code registered by previously photographing iris patterns of a user permitted to access the terminal. - View Dependent Claims (19, 20, 21, 22, 23, 24)
