Device for recognizing image and device for reading image
View Patent ↗The disclosure provides a device for recognizing an image and a device for reading an image. The device for recognizing the image includes a circuit board ( 50 ) on which a plurality of light sources ( 20 ) are arranged, the multiple light sources ( 20 ) which are configured to supply multiple lights in different directions to the image to be recognized, and an imaging component configured to uniformly image the lights diffused by the image to be recognized so as to recognize the image to be recognized. The disclosure solves the problem that the device for recognizing the image in the relevant technology may only supply one single light emitting direction, and the device for recognizing the image has a beneficial effect of recognizing a hologram including various pieces of image information.
1. A device for recognizing an image, comprising:
a circuit board ( 50 ) configured to arrange multiple light sources ( 20 );
the multiple light sources ( 20 ) configured to supply various lights in different directions to an image to be recognized;
an imaging component configured to uniformly image lights diffused by the image to be recognized to recognize the image to be recognized;
wherein the imaging component comprises:
a lens ( 40 ) configured to uniformly image the lights, from the multiple light sources ( 20 ) and diffused by the image to be recognized, and project the lights imaged to a photoelectric conversion chip ( 60 );
the photoelectric conversion chip ( 60 ), configured to perform photoelectric conversion on the received lights to generate electric signals so as to generate an image, wherein the generated image is used for recognizing the image to be recognized;
the device further comprises:
a supporting device ( 70 ) arranged on the circuit board ( 50 ) and configured to support the lens ( 40 ) to enable the lens ( 40 ) to be suspended above the photoelectric conversion chip ( 60 ), wherein the photoelectric conversion chip ( 60 ) is arranged on the circuit board ( 50 ); the multiple light sources ( 20 ) are circumferentially arranged on the circuit board ( 50 ) in a manner of surrounding the supporting device ( 70 ); and
a transparent plate ( 30 ), wherein a funnel-shaped sealing space is formed between the transparent plate ( 30 ) and the supporting device ( 70 ) and the lens ( 40 ) to enable the image to be recognized placed on the transparent plate ( 30 ) to diffuse lights from the multiple light sources ( 20 ) to the lens ( 40 ).
2. The device according to claim 1 , wherein the multiple light sources ( 20 ) are circumferentially arranged on the circuit board ( 50 ).
3. The device according to claim 2 , wherein the number of the multiple light sources ( 20 ) is equal to or greater than three and the multiple light sources ( 20 ) are at least provided with three light emission directions.
4. The device according to claim 3 , wherein the multiple light sources ( 20 ) are independently controlled to emit the light or are combined to perform combined light emission.
5. The device according to claim 4 , wherein the multiple light sources ( 20 ) being combined to perform the combined light emission comprises:
every two or three of the multiple light sources ( 20 ) are combined to perform the combined light emission.
6. The device according to claim 1 , wherein the lens ( 40 ) is a circular lens, and image distance of the lens ( 40 ) is smaller than a threshold value.
7. A device for reading an image, comprising the device for recognizing the image according to claim 1 , wherein the device for reading the image is configured to generate an image according to the signals output by the device for recognizing the image to recognize the image to be recognized.
8. A device for reading an image, comprising the device for recognizing the image according to claim 2 , wherein the device for reading the image is configured to generate an image according to the signals output by the device for recognizing the image to recognize the image to be recognized.
9. A device for reading an image, comprising the device for recognizing the image according to claim 6 , wherein the device for reading the image is configured to generate an image according to the signals output by the device for recognizing the image to recognize the image to be recognized.
