Embodiment 1

[0026] The embodiment of the present invention provides an image recognition device, figure 2 Is a structural block diagram of an image recognition device according to an embodiment of the present invention, such as figure 2 As shown, the device includes a circuit board 50, a plurality of light sources 20, and an imaging component 110.

[0027] The circuit board 50 is used to place multiple light sources 20; the multiple light sources 20 are used to provide a variety of different directions of light to irradiate the image to be recognized; the imaging component 110 is used to uniformly image the diffused light of the image to be recognized to For identifying the image to be identified.

[0028] Through the above structure, the single light source in the related technology is changed, and the problem that different image information cannot be recognized at different angles or directions in the related technology is solved, and the hologram multiple image information recognition is ...

Embodiment 2

[0039] image 3 Is a cross-sectional view of an image recognition device according to a preferred embodiment of the present invention, such as image 3 As shown, the image recognition device includes a frame 10, a light source 20, a glass plate 30, a lens 40, a circuit board 50, a photoelectric conversion chip 60, and a supporting device 70. The structure and function of the above-mentioned components are the same as those in the prior art, and they are not here. Repeat it again.

[0040] The body of the image recognition device is a rectangular parallelepiped constructed by the frame 10, and the bottom plate is composed of a circuit board 50. A photoelectric conversion chip 60 is mounted on the circuit board 50. A supporting device 70 is provided at the center of the circuit board 50 for supporting the lens 40. , The lens 40 is suspended above the photoelectric conversion chip 60. A plurality of light sources 20 are installed on the circuit board 50 around the supporting device ...

Embodiment 3

[0043] The embodiment of the present invention provides an image reading device. The image reading device includes the image recognition device provided in the second embodiment. The image reading device is used to generate an image according to the signal output by the image recognition device for identifying Identify the image.

[0044] Such as image 3 As shown, when working, the image to be recognized is placed on the transparent plate 30 of the image recognition device, and the multiple light sources 20 are assumed to be Figure 4 Wherein, the light source 21 and the light source 26 are arranged in the same light emission direction, the light source 22 and the light source 25 are arranged in the same light emission direction, and the light source 23 and the light source 24 are arranged in the same light emission direction. The light from the light source 21 to the light source 26 in different directions is irradiated on the image to be recognized through the transparent plate...

Abstract

Provided are an image recognition device and an image reading device. The image recognition device comprises: a circuit board (50) which is set to place a plurality of light sources (20); the plurality of light sources (20) which are set to provide various light in different directions irradiated on an image to be recognized; and an imaging assembly which is set to uniformly image the light diffused by the image to be recognized for recognizing the image to be recognized. The present invention solves the problem in the related art that the light sources in an image recognition device only provide a single light-emitting direction, and has the beneficial effect that a hologram containing multiple types of image information can be recognized.

Description

Technical field [0001] The present invention relates to the field of image recognition, and in particular to an image recognition device and an image reading device. Background technique [0002] figure 1 Is a cross-sectional view of a contact image sensor based on related technologies, such as figure 1 As shown, the contact image sensor used in image reading devices such as related multifunction machines, dedicated scanners, fax machines, etc., is provided with a glass plate 3 above the frame 1, and a circuit board 5 under the frame 1. A row of photoelectric conversion chips 6 is provided on the board 5, a row of linear lens 4 is provided above the photoelectric conversion chip 6, and a light source 2 is provided on one side of the linear lens 4. The light source of this contact image sensor emits light on the side of the linear lens. Only one light direction is provided. [0003] With the expansion of application fields, more and more requirements are put forward for the functio...
