ABSTRACT:
A novel control system for image input device, especially fingerprint image input device, is disclosed. The control system comprises a fingerprint image input device selection module, an instruction conversion module and a fingerprint image size determination module. The fingerprint image input device selection module selects a particular fingerprint image input device from a variety of fingerprint image input devices. The instruction conversion module generates, upon an image capture instruction or a match instruction from a fingerprint verification software, particular image capture instructions to a the selected fingerprint image input device, wherein the instruction pertains to a specification of image as selected by a user or determined with a particular method. The fingerprint image size determination module determines the specification, including the resolution and the size of fingerprint image to be captured. The fingerprint image input device then capture a fingerprint image according to the instruction, under the selected or designated specification. This invention also discloses a method to determine a basic point and to capture a fingerprint image within an area based on the basic point.
