In one embodiment, a sensor system includes an active thermal sensor pixel matrix, a plurality of presence sensors, and an image acquisition controller. The pixel matrix includes a plurality of pixels arranged in a plurality of rows and a plurality of columns and a boundary defining a perimeter. The plurality of presence sensors is disposed at least partially within the boundary of the pixel matrix. The image acquisition controller is coupled to the pixel matrix and the plurality of presence sensors. The image acquisition controller is configured to: (i) receive signals from the presence sensors; (ii) identify, based on the signals, a scan region, wherein the scan region is a portion of the pixel matrix that is in contact with or adjacent to a specimen; and (iii) obtain image data only from pixels that are within the scan region for generating an image of the specimen.

In one aspect, a sensor includes an image acquisition controller and a pixel array. The pixel array includes a first set of pixels electrically coupled to the controller and a second set of pixels electrically coupled to the controller. The sensor is configured to operate in a first mode and a second mode. When operating in the first mode, the controller is configured to acquire signals from only the first set of pixels for generating a low-resolution image. When operating in the second mode, the controller is configured to acquire signals from both the first set of pixels and the second set of pixels for generating a high-resolution image.

Sensors configured to operate at multiple resolutions

The invention relates to a method for testing a fingerprint whose reference data are stored in a portable data carrier. The reference data contain at least positions and orientations of minutiae and pores and an orientation vector. According to the invention it is provided that the testing of the fingerprint includes first sensing measuring values stating the actual value of the sensed fingerprint and extracting the minutiae and the pores from said measuring values. Then the reference data of the minutiae and the orientation vector are read from the portable data carrier and the minutiae from the sensed fingerprint compared with the corresponding reference data. Subsequently, the position of the pores relative to the minutiae is transmitted to the portable data carrier and the pores are checked in the portable data carrier.
