Image acquisition apparatus and biometric recognition device

Abstract

The present disclosure provides an image acquisition apparatus and a biometric recognition device, belonging to the technical field of biometric recognition. The image acquisition apparatus includes: a light source, a reflective array, and an imaging component. The reflective array is located on a light exit side of the light source. The light source is configured to emit light toward the reflective array. The reflective array is configured to reflect the light toward a to-be-recognized palm to form at least one light spot pattern on the to-be-recognized palm. The imaging component is configured to receive the light reflected by a surface of the to-be-recognized palm and output a to-be-recognized image. The image acquisition apparatus of the present disclosure can avoid an attack of a planar non-living palm such as a paper print or a picture, thereby achieving a good liveness detection effect.
