摘要： An electronic apparatus and a texture recognition device are described that relate to image recognition technologies. The texture recognition device includes a sensing layer, a transparent contact layer, a light shielding layer, and a plurality of light sources. The sensing layer includes a plurality of photosensitive units distributed in an array; the transparent contact layer is disposed on a side of the sensing layer; the light shielding layer is disposed between the sensing layer and the transparent contact layer, and including a plurality of light transmission portions arranged in an array; and the light sources are distributed in an array on a side of the light shielding layer close to the transparent contact layer, and light emitted by the light sources is reflected by the transparent contact layer and transmitted to the photosensitive units by passing through the light transmission portions.
