Abstract: A drive method for a texture recognition device and a texture recognition device. The texture recognition device includes a light source array and an image sensor array. The image sensor array includes a plurality of image sensors, the plurality of image sensors are configured to receive light emitted from the plurality of sub-light sources and then reflected by a texture to the plurality of image sensors for a texture collection; the drive method includes: at a first moment, the light source array operating to provide a first photosensitive light source, and at the first moment or a second moment different from the first moment, the light source array operating to provide a second photosensitive light source. A first imaging range of the first photosensitive light source on the image sensor array partially overlaps a second imaging range of the second photosensitive light source on the image sensor array.
