摘要： Pre-image-acquisition information is obtained by a digital camera and transmitted to a system external to the digital camera. The system is configured to provide image-acquisition settings to the digital camera. In this regard, the digital camera receives the image-acquisition settings from the external system and performs an image-acquisition sequence based at least upon the received image-acquisition settings. Accordingly, the determination of image-acquisition settings can be performed remotely from the digital camera, where data-processing resources can greatly exceed those within the digital camera.

摘要： An electronic camera for producing an output image of a scene from a captured image signal includes a first imaging stage comprising a first image sensor for generating a first sensor output and a first lens for forming a first image of the scene on the first image sensor, and a second imaging stage comprising a second image sensor for generating a second sensor output and a second lens for forming a second image of the scene on the second image sensor, where the lenses have different focal lengths. A processing stage uses the sensor output from one of the imaging stages as the captured image signal and uses the images from both imaging stages to generate a range map identifying distances to the different portions of the scene.

7.发明授权Fixed pattern noise removal in CMOS imagers across various operational conditions 有权在各种操作条件下，CMOS成像器中的固定图案噪声去除公开(公告)号：US07092017B2

摘要： CMOS imagers can possess higher levels of imager noise than their predecessors, CCDs. This noise can be of the form of temporal variation and fixed pattern. The fixed pattern component of this noise can be removed, which is known already in the art. The invention in this disclosure is that proper correction can be developed for all imager conditions (imager integration time and imager temperature) using a single FPN (fixed pattern noise) dark map, a single FPN PRNU (pixel response nonuniformity) map, imager integration time and imager temperature. Without this invention, a dark frame capture and a flat field capture (integrating sphere), are required before every image capture, a practical impossibility in typical picture taking. Further, the estimates of both FPN maps (dark and PRNU) in this invention are improved estimates relative to such captured directly preceding image capture since such have be formed with multiple frame averaging at calibration time, thus removing any temporal noise from these map estimates. These dark FPN and PRNU FPN maps are modified by a scaling and biasing functional with the measured values of integration time and of imager temperature. A second approach is to make the biasing and scaling functions dependant only on mean dark response taken from the imager's dark pixels, at time of capture.

摘要： An imaging system and method for producing a digital image from pixel signals captured by a pixel array is disclosed. First pixel signals, generated during a first exposure period, are read out from a first group of pixels of the pixel array. The first group of pixels is reset after reading out the first pixel signals.Second pixel signals from the first group of pixel are read out after resetting the first group of pixels. The second pixel signals are generated during a second exposure period. Third pixel signals from a second group of pixels of the pixel array are read out. The third pixel signals are generated during a third exposure period that overlaps at least a portion of the first and second exposure periods. The first, second, and third pixel signals are used to produce the digital image.
