    摘要: Provided are a rolled fingerprint acquisition apparatus and method for automatically detecting the start and end of registration and synthesis to acquire an accurate fingerprint. The rolled fingerprint acquisition apparatus compares at least one of fingerprint characteristic information and the amount of variation between the fingerprint characteristic information to reference fingerprint characteristic information to determine whether to start or end registration and synthesis, wherein the fingerprint characteristic information is information about fingerprints included in rolled fingerprint frames that are sequentially acquired, and registers and synthesizes the rolled fingerprint frames according to the result of the determination.
