Abstract:
The iris recognition device includes an iris camera module used for collecting iris characteristics of a user, and at least one fill light component used for providing a supplementary light source for the iris camera module. When the iris recognition device is used for collecting the iris characteristics of the user, the supplementary light source provided by the fill light component reduces reflective spots on the iris or make reflective spots in areas other than iris such as sclera and pupil, thereby improving precision of the collected iris characteristics of the user.

Claim (Index 22):
The manufacturing method, as recited in  claim 20 , wherein a pixels diameter of said image sensor chip is D, a number of said horizontal maximum output pixels is X, and a number of said vertical maximum output pixels is Y, wherein a farthest distance of preset binoculus iris recognition is c, according to a minimum requirement of said iris recognition algorithms to pixels which is N pixel/mm, said number of pixels needs to be not less than f*N in said farthest distance c and in a range of f, and said corresponding image size of said image sensor chip  111  is f*N*D,\n wherein according to a principle of similar triangles, a proportional relation is (f*N*D)/f=a/(c\u2212a), wherein under a condition of known N, D, c, a focal length a of said iris camera module is a=c*D*N/(D*N+1), \n wherein based on a principle of similar triangles that is X*D/e=a/(c\u2212a), in said farthest distance c, a horizontal maximum shooting range of said iris camera module is e=X*D*(c\u2212a)/a, \n wherein according to a principle of similar triangles: (b\u2212a)/a=f/(X*D); a closest distance of user binoculus iris recognition b after being calculated is: b=[f/(X*D)+1]*a; and \n wherein according to a principle of said triangle function that is tan (\u03b2/2)=(e/2)/(c\u2212a), a horizontal field angle \u03b2 of said iris camera module after being calculated is \u03b2=2*arc tan [(e/2)/(c\u2212a)].
