Abstract
The utility model discloses the iris capturing module that a kind of infrared illumination and camera module integrate, aim to solve the problem that traditional scheme infrared illumination and camera module are separately installed, brightness disproportionation, the problem of consumption heating is big, iris capturing module of the present utility model includes infrared lamp, infrared camera module, infrared spectroscope, and the infrared camera module includes camera lens and CMOS；Infrared lamp and camera module are integrated into a module side by side；Infrared spectroscope is arranged on infrared lamp direction of illumination, and infrared lamp emergent light is divided into two grade beams of certain angular interval, illuminates user's eyes respectively.It is this module small volume, easy for installation, low in energy consumption, suitable for the integrated of the equipment such as mobile phone, tablet personal computer.
Description
Technical field
A kind of iris capturing module is the utility model is related to, more particularly to a kind of infrared illumination integrates with camera module
Iris capturing module.
Background technology
The common solution of current mobile device addition iris identifying function is by infrared illumination in iris capturing module
It is discretely located with camera module, infrared lamp is pointed into ocular, and the program needs large range of infrared light covering user double
Eye, light utilization ratio is relatively low, and the big heating of power consumption is big, the circular light spot that infrared lamp is formed, place between the eyebrows among oblique illumination two
Region, right and left eyes brightness is inconsistent, and outside brightness is inconsistent in eyes, and picture quality is low, influences accuracy of identification.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art part, there is provided a kind of low-power consumption, high integration, Gao Tu
The iris capturing module of tablet quality.
The utility model is achieved through the following technical solutions.
Infrared lamp includes infrared lamp, infrared camera module and infrared point with the iris capturing module that camera module integrates
Light device, infrared lamp and camera module are integrated in a module side by side, and infrared spectroscope is arranged on above infrared lamp, by infrared lamp
Illumination region is divided into two pieces of hot spots, illuminates user's eyes.
Tilted compared to single beam infrared light that traditional scheme infrared lamp is sent and illuminate user's eye, the utility model has such as
Lower beneficial effect.
1. infrared spectroscope is emitted two beam infrared lights illuminates user's eyes respectively, improve light utilization ratio, reduce power consumption,
Heating, right and left eyes brightness is consistent, and outside brightness is consistent in eyes, improves picture quality and accuracy of identification.
2. the non-perpendicular irradiation user's eye of emergent light can avoid eye reflective, recognition success rate is improved.
3. it is modular integrated, it is simple in construction, it is easily installed, it is not necessary to calculate respectively between infrared illumination and camera module
Away from and angle.
Brief description of the drawings
Fig. 1 is prism schematic diagram.
Fig. 2 is the iris capturing module stereogram using prism.
Fig. 3 is each component drawings of iris capturing module using prism.
Embodiment
The utility model is further described with reference to example and accompanying drawing, but application mode of the present utility model is unlimited
In this, based on the utility model, what those of ordinary skill in the art were obtained on the premise of it need not carry out creative work
Every other application is in the scope of protection of the utility model.
As shown in figure 1, a branch of incident light can be divided into two beams by prism；It can consider to use distance design prism in advance
Angle is divided, so as to control outgoing light direction.
Preferably, this example is using prism as optical splitter, and Fig. 2 is using the iris capturing module stereogram of prism, institute
The iris capturing modular assembly using prism is stated as shown in figure 3, including prism 31, infrared lamp 32 and camera module 33, this reality
Infrared lamp 32 and camera 33 are integrated in a module side by side in example, and prism 31 is arranged on above infrared lamp, two outgoing of prism
Light forms two pieces of hot spots in user's eye and illuminates user's eyes, camera shooting eyes image.
