Below with reference to Fig. 1-Fig. 2, the CCD camera assembly 100 according to the utility model embodiment is described.
As Figure 1-Figure 2, according to the CCD camera assembly 100 of the utility model embodiment, comprising: lens assembly 110, imageing sensor 120, infrared light supply 130 and narrow band pass filter 140.It should be noted that there is according to the CCD camera assembly 100 of the utility model embodiment the function identifying iris.
Specifically, as shown in Figure 1, infrared light supply 130 launches Infrared to iris, the Infrared that the light around narrow band pass filter 140 pairs of lens assemblies 110 filters iris is reflected through.It should be noted that, " around light " here can comprise in the light signal that in available light, ambient light and CCD camera assembly 100, miscellaneous part sends one or more.Imageing sensor 120 is positioned at the below of lens assembly 110 to gather the Infrared of described reflection.
Such as, as shown in Figure 1, infrared light supply 130 launches Infrared, and imageing sensor 120 is positioned at the below (below shown in Fig. 1) of lens assembly 110 to gather the light through lens assembly 110.The Infrared that infrared light supply 130 is launched is gathered and imaging by imageing sensor 120 after the iris reflex, lens assembly 110 of eyes.Narrow band pass filter 140 is suitable for will to be gathered by imageing sensor 120 and all light of imaging filter.Consider that iris is to the sensitivity of Infrared, and coordinate the instantaneous exposure function of imageing sensor 120, can collect under very high shutter speed clearly, high-quality iris image, the impact of rocking for graphical quality can be eliminated in gatherer process like this.
Narrow band pass filter segments from bandpass filter, its definition is identical with bandpass filter, that is this optical filter allows light signal to pass through at specific wave band, and two optical signals departed from beyond this wave band are prevented from, the passband of narrow band pass filter is narrow comparatively speaking, is generally less than 5% of centre wavelength value.Here, the light in particular range of wavelengths can pass narrow band pass filter 140, and is incident upon to obtain corresponding image information on imageing sensor 120, and the light outside particular range of wavelengths cannot be projected on imageing sensor 120 by narrow band pass filter 140 prevention.
Because the reflectivity of iris to Infrared is higher and eyes are invisible, can utilize narrow band pass filter 140 that the Infrared in particular range of wavelengths is projected on imageing sensor 120 thus, thus CCD camera assembly 100 can gather iris image.Such as, as shown in Figure 1, the Infrared that infrared light supply 130 is launched is irradiated on eyes 200 along the direction shown in the arrow a1 in Fig. 1, be reflected back after Infrared arrival eyes 200 iris of specific wavelength, Infrared after eyes 200 reflect is delivered on narrow band pass filter 140 along the direction shown in arrow a2 in Fig. 1, narrow band pass filter 140 allows the Infrared of specific wavelength pass with very high transmitance, finally received by imageing sensor 120 and be converted to picture signal and output to image procossing end and process, and the large portion of veiling glare in environment is filtered out by narrow band pass filter 140, such as light edge is as arrow b1 in Fig. 1, direction shown in b2 is transmitted and cannot be projected to imageing sensor 120 place, the signal to noise ratio (S/N ratio) of iris image can be increased like this, thus high-quality iris image can be obtained.Thus, high-quality iris image can be obtained under open environment, thus reduce the requirement of iris identifying function to environment, and then reduce the cost of the CCD camera assembly 100 with iris image acquiring function.
According to the CCD camera assembly 100 of the utility model embodiment, by utilize iris to infrared reflectivity the high and sightless feature of eyes, increase optical narrow-band optical filter 140 in the optical path, reduce the interference of lens assembly 110 periphery bias light, coordinate infrared light supply 130 floor light simultaneously, to improve signal noise ratio (snr) of image, thus under the light condition in open environment for use, in natural lighting, can obtain high-quality iris image.
