摘要： A digital pixel driver that operates in response to an M-bit digital input value defining the apparent brightness of the pixel. The pixel driver generates a pixel drive signal having a duty cycle that sets the apparent brightness of the pixel. The pixel driver comprises a memory, a digital sequence generator and a comparator. The memory receives and stores an N-bit word that represents the digital input value. The digital sequence generator generates a digital sequence of P-bit digital values that defines the temporal duration of the pixel drive signal and includes a first P-bit word that represents at least part of the digital input value at a location temporally corresponding to the duty cycle of the pixel drive signal as defined by the at least part of the digital input value. The comparator is connected to receive the digital sequence from the digital sequence generator and a second P-bit word from the memory. The second P-bit word constitutes at least part of the N-bit word. The comparator includes an output that provides the pixel drive signal and that changes state in response to correspondence between the first P-bit word and the second P-bit word.

摘要： An imaging system for imaging a fingerprint operates in at least two different modes to provide both finger recognition and finger navigation applications. A light source illuminates a swipe interface having an elongated sensing area upon which a user swipes a finger. Light reflected from the finger is captured by an optical image sensor as image data representing a sequence of images resulting from motion of the digit over the sensing area of the swipe interface. The captured image data is output by the optical image sensor for processing of the data in one of the at least two different modes.

摘要： An on-chip system and method for calibrating an illumination source includes a photo-detector and intensity sense and control circuitry resident on an integrated circuit. The integrated circuit is illuminated by an illumination source, which impinges upon the photo-detector. The intensity sense and control circuitry receives the measured intensity value of the illumination source and compares the measured intensity to a predetermined value representing the desired intensity. Subject to a range of operation, the intensity sense and control circuitry adjusts the intensity of the illumination source based upon the difference between the measured illumination intensity and the desired illumination intensity.

摘要： The analog drive circuit drives a pixel electrode in response to an analog sample derived from a video signal. The analog drive circuit comprises a sample selection section and a drive signal generator. The sample selection section receives and temporarily stores the analog sample during a sample load period. The drive signal generator generates a drive signal and applies the drive signal to the pixel electrode during a display period that follows the sample load period. The drive signal is composed of a sequence of a first temporal portion and a second temporal portion. The first temporal portion has a time duration substantially proportional to the analog sample temporarily stored in the sample selection section. The second temporal portion is the temporal complement of the first temporal portion.
