摘要： Disclosed are various embodiments of methods and corresponding devices for effecting such methods that permit integrated circuits, sensors, chips or dies to be identified. Imperfections or irregularities in pixels or memory cells are used to generate identification codes for integrated circuits, sensors, chips or dies. Addresses or data locations of selected defective pixels or memory cells may be used to generate such identification codes.

摘要： Disclosed are various systems, devices and methods for digital camera image stabilization. In one embodiment, a digital camera captures a plurality of digital images of a subject simultaneously or near-simultaneously and stores the captured images in memory as individual digital data sets. While the digital images are being captured simultaneously or near-simultaneously by means of a plurality of rolling shutters, a relative position determination device such as an angular rate sensor is employed to sense and save to memory data representative of the relative positions of the digital camera at the moments the individual digital images or frames are being exposed. Spatial shift directions and magnitudes are calculated in a processor of the camera on the basis of such data, and then applied to the individual data sets to form aligned data sets comprising aligned data points. To compensate for camera shake occurring while the individual images were being captured, the aligned data sets are added together to form an output data set representative of an output image.
