Description

technical field [0001] The invention relates to the field of fingerprint devices, in particular to an anti-jamming device based on a capacitive sensing fingerprint collection device and a method thereof. Background technique [0002] Semiconductor fingerprint sensors, which began in 1998, use a variety of novel technical means to realize fingerprint image acquisition, including semiconductor capacitive sensors, semiconductor pressure-sensitive sensors, semiconductor temperature-sensitive sensors, etc. Among them, silicon capacitive fingerprint sensors are the most widely used. Unlike optical devices, which mostly use manual adjustments to improve image quality, semiconductor fingerprint sensors use automatic control technology to adjust the sensitivity of fingerprint image pixel lines and local areas of fingerprints, and combine feedback information to generate high-quality images in different environments. Thanks to the local adjustment capability provided, even images with...
