| 摘要 |
The present invention relates to systems and methods for enhancement of biometric object image capturing. These systems and methods prevent undesirable interruptions of total internal reflection of a prism that result in improper biometric images. In embodiments of the invention, a thermal assembly comprising a plurality of thermal elements is placed adjacent to the image capturing device. The thermal elements upon supply of a current are capable of either heating or cooling the image capturing device or a platen of the image capturing device. If cooling of the biometric object receiving surface is required, the thermal elements can be controlled to decrease temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed. If heating of the biometric object receiving surface is required, the thermal elements can be controlled to increase temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed, to remove and prevent accumulation of moisture.
