Abstract
The present disclosure provides a spectral imaging chip and apparatus, an information processing method, a fingerprint living body identification device and a fingerprint module. The spectral imaging chip can obtain spectral information of a captured object without affecting the spatial resolution and imaging quality of the resulting image, which is convenient for grasping more comprehensive information of the object to be imaged. The fingerprint living body identification device and fingerprint module can realize fingerprint living body identification through the spectral imaging chip, which is advantageous to improve the stability of the component performance, while reducing the volume, weight and cost of the spectral components, greatly improving the anti-counterfeiting ability of the fingerprint identification system.
