The lens 11 is composed of at least one lens. The lens 11 has an image capturing area for capturing an image. The image captured by the lens 11 is diffracted to the image sensing component 12, and the image sensing component 12 is The image of the lens 11 is converted into a signal and then transmitted to a processor (not shown in the drawing) for processing, and is displayed by the display (not shown) and recognized.

However, the lens 11 only has an image capturing area for capturing images, a single image. As the basis of the recognition of multi-point features on the face, on the one hand, the recognition speed is slowed down. On the other hand, the noise generated by nature will make the periphery of the captured image blur, which makes the identification difficult.

Therefore, how to provide a multi-face image at the same time and to make the image clear to facilitate identification has been an urgent problem for the photographic manufacturer.

The main purpose of the present invention is to provide a face recognition photographing device, which is mainly intended to overcome the conventional photographing device for face recognition, and cannot quickly provide images with clear facial features as a basis for identification.

To this end, the main technical means adopted by the present invention is to provide a face recognition photographing device, which includes at least one camera lens module having a plurality of image capturing optical application areas, and a receiving lens module. The image sensing component that captures the image and optically converts the image into a signal; wherein the plurality of image capturing optical application regions of the camera lens module can be assigned different optical wavelengths and synchronized without time difference They are used for face photography and face image capture.

The effect that the present invention can achieve by the above-mentioned main technical means is that the imaging device has a plurality of image capturing optical application regions, and the plurality of image capturing optical application regions can be different optical wavelengths and synchronized without time difference. Each face is photographed and captured as a face image; the photographing device can use the face images of different features as the basic information of the image, and the spatial and temporal reference and average of the face images of the different features are averaged. After that, the external interference can be effectively removed, thereby clearing the captured face image, and then clearly displaying the features of the face as a basis for identification. To enhance the use of face recognition photography devices.
