Drive method for texture recognition device and texture recognition device

A drive method for a texture recognition device, wherein the texture recognition device comprises:

• a light source array, comprising a plurality of sub-light sources;
• and
• an image sensor array, on a side of the light source array, and comprising a plurality of image sensors, wherein 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 comprises:
• 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,
• wherein a first imaging range of the first photosensitive light source on the image sensor array partially overlaps with a second imaging range of the second photosensitive light source on the image sensor array.
