A device for recognizing an image, comprising: a circuit board configured to arrange multiple light sources; the multiple light sources configured to supply various lights in different directions to an image to be recognized in sequence; an imaging component configured to uniformly image lights diffused by the image to be recognized with various lights in different directions, wherein the generated image by imaging component is used for recognizing the image to be recognized; wherein the imaging component comprises: a lens configured to uniformly image the lights, from the multiple light sources and diffused by the image to be recognized, and project the lights imaged to a photoelectric conversion chip; the photoelectric conversion chip,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; wherein the device further comprises a supporting device arranged on the circuit board and configured to support the lens to enable the lens to be suspended above the photoelectric conversion chip, wherein the photoelectric conversion chip is arranged on the circuit board; characterised by further comprising: the multiple light sources are circumferentially arranged on the circuit board in a manner of surrounding the supporting device; wherein the lens is a circular lens, and image distance of the lens is smaller than a preset threshold value; the device further comprises a transparent plate, wherein a funnel-shaped sealing space is formed between the transparent plate and the supporting device and the lens to enable the image to be recognized placed on the transparent plate to diffuse lights from the multiple light sources to the lens. a circuit board configured to arrange multiple light sources;
