Description

Portrait identification photography module

【Technical field】

A kind of portrait identification photography module, espespecially a kind of portrait recognized applied to electronic equipment or the enterprising pedestrian's picture of running gear Identification photography module.

【Background technology】

Existing camera device on the market is mainly used in shooting photo or records short-movie and carry out networking video signal, but can not be complete The full up increasing human-computer interaction requirement of sufficient people, user need the man-machine interaction experience of simpler more convenient and quicker, because The personage of this this skill develops human-computer interaction interface, in the existing camera having because being confined to hardware and capture skill Art, and the cost of camera mechanism great number, therefore can not be widely used in display device, also without decree camera Work of the interactive application in face's characteristic identification can be popularized.

Traditional face detection is based primarily upon the face recognition of visible images, but this mode has and is difficult to overcome The defects of, when ambient lighting changes, recognition effect can drastically decline, and can not meet the needs of real system, such as clap According to when run into sidelight when " negative and positive face " black and white phenomenon for occurring, it is possible to can not correctly identify.

Another person, colour phhotograpy camera lens also easily because in the case of light refraction reflection source deficiency, make the face of face Characteristic produces shade the problems such as causing characteristic unobvious, in turn results in the problems such as can not judging and judging by accident.

【The content of the invention】

Therefore, it is the shortcoming of the above-mentioned known technology of solution, the main purpose of the present invention, there is provided one kind can lift face recognition essence The portrait identification photography module of degree.

For up to above-mentioned purpose, the present invention provides a kind of portrait identification photography module, comprising：One circuit substrate, a photography Device, at least an infrared LEDs luminescence unit, an image processor, a connector；

The circuit substrate has one first side and one second side, is correspondingly arranged at the upper and lower both sides of the circuit substrate.

The camera has an image sensing chip and an optical filter and a lens base and a camera lens, photography dress The such component put corresponds to stacked group and set, and the image sensing chip is electrically connected with the circuit substrate.

The first side that the infrared LEDs luminescence unit is arranged at the circuit substrate be disposed adjacent with the camera and with The circuit substrate is electrically connected with.

The image processor is arranged at the first side of the circuit substrate and is electrically connected with the circuit substrate.

The connector is arranged at the first side of the circuit substrate and is electrically connected with the circuit substrate.

The present inventor passes through single camera as identification photography module（Image receptor (CMOS)）And image processor, Face identification functions are realized, and cost can be reduced；Use active infrared line LED luminescence units（Near infrared ray）Face imaging and Chromatic image combine allows recognition of face not under the influence of by ambient light produce high-quality facial image, through brightness of image, Image uniformly, contrast, obtain higher discrimination, obtain more high-res face characteristic identification effect.

For being applied portrait identification photography module and being incorporated into action or display device, manufacturing cost can be reduced and reached The change profit of man-machine interaction application.

【Embodiment】

Fig. 1,2,3 are referred to, are first embodiment stereo decomposing and constitutional diagram and start of the present inventor as identification photography module Schematic diagram, as illustrated, portrait identification photography module 1, comprising：It is one circuit substrate 11, a camera 12, at least one red Outside line LED luminescence units 13, an image processor 14, a connector 15；

The circuit substrate 11 has one first side 111 and one second side 112, is correspondingly arranged at the 11 upper and lower both sides of circuit substrate, The circuit substrate 11 is a kind of multilayer circuit board.

The camera 12 has an image sensing chip 121 and an optical filter 122 and a lens base 123 and a mirror First 124, such component of the camera 12 corresponds to stacked group and set, and the image sensing chip 121 and the circuit substrate 11 are electrical Connection, overall Ke Shi Jiao≤35 degree of the camera 12.

Described image sensing wafer 121 is combined with the circuit substrate 11 passes through COB (Chip On Board) processing procedure, by this Image sensing chip 121 is integrated and routing is arranged in the circuit substrate 11.

The optical filter 122 is a kind of two waveband narrow band pass filter, and the optical filter 122 is placed in camera 12, and is allowed Near infrared ray produced by infrared LEDs luminescence unit 13 by while filter other ambient lights, for isolating interference light, connect Receive flashlight and fully highlight useful information reduction interference.

The infrared LEDs luminescence unit 13 is arranged at the first side 111 and the phase of camera 12 of the circuit substrate 11 Neighbour sets and is electrically connected with the circuit substrate 11, and infrared LEDs luminescence unit 13 described in the present embodiment is arranged at photography dress 12 arranged on left and right sides are put, the smooth source range≤780nmLED of the infrared LEDs luminescence unit 13.
