Abstract

A 500-dpi 224×256-pixel single-chip fingerprint identification LSI adapts the sensing circuit to a finger and performs pixel-parallel image processing and rotation in a pixel array. A test chip achieves 2 ms 10 mW sensing, 41 ms 19.2 mW identification, and practical identification accuracy at 2.5 V, 5 MHz.
