Abstract

The invention provides an image recognition device and an image reading device. The image recognition device comprises a circuit board (50), a plurality of light sources (20) and an imaging assembly, wherein the circuit board (50) is used for placing the plurality of light sources (20), the plurality of light sources (20) are used for providing light in different directions to light on an image to be recognized, and the imaging assembly is used for enabling light diffused by the image to be recognized to evenly image to recognize the image to be recognized. The image recognition device and the image reading device solve a problem that a light source of the image recognition device in relevant technology only provides a single lighting direction and can recognize a hologram including a plurality of kinds of image information.

Description

technical field [0001] The invention relates to the field of image recognition, 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 according to related art, such as figure 1 As shown, the contact image sensor used in image reading devices such as related multi-functional all-in-one machines, special scanners, and facsimile machines is provided with a glass plate 3 above the frame 1, and a circuit board 5 is arranged under the frame 1. A row of photoelectric conversion chips 6 is arranged on the board 5, a row of linear array lenses 4 is arranged above the photoelectric conversion chips 6, and a light source 2 is arranged on one side of the linear array lenses 4. The light source of this contact image sensor emits light on one side of the linear array lens, and the light source Only one light direction is provided. [0003] With the expansion of application fie...
