摘要： A method of operating an image sensor apparatus is provided. In this method, first digital image data is generated based on a first exposure data signal, wherein the first exposure data signal is indicative of an exposure level of the image sensor during a first exposure period. The first digital image data is stored in a storage circuit. Second digital image data is generated based on a second exposure data signal, wherein the second exposure data signal is indicative of an exposure level of the image sensor during a second exposure period. The second exposure period is different from the first exposure period. The second digital image data associated with the image sensor is selectively stored based on a value of the first digital image data associated with the image sensor.

摘要： In a method for out-of-gamut color correction of images, the image is color corrected by compressing pixel vectors having a maximal component located outside of the output color gamut to within the output color gamut while retaining a hue of the image. An electronic imaging system includes an image signal processor configured to color correct the image for display by the output device by compressing pixel vectors having a maximal component located outside of the output color gamut to within the output color gamut while retaining a hue of the image.

摘要： A computerized system for mapping an atmospheric phenomenon in a geographic region. Multiple free-space electromagnetic communications links are previously distributed in the geographic region. The system includes an interface to monitoring mechanisms attached respectively to the free-space electromagnetic communications links. The monitoring mechanisms respectively monitor attenuation levels of the free-space electromagnetic communications links. A processor simultaneously processes the attenuation levels, and maps in the geographic region the atmospheric phenomenon. The simultaneous processing preferably applies a non-linear model which relates the attenuation levels the atmospheric phenomenon, and solves a tomographic problem based on the non-linear model and the attenuation levels. The tomographic problem is preferably solved by an interactive algorithm based on consecutive refinement and linear inversion at each iteration. Alternatively, an interpolation is performed based on respective inverse distance from the communications links. Preferably, the interpolation is further based on respective lengths of communications links. A data interface preferably provides to subscribers temporal information related to the atmospheric phenomenon within portions of the geographic region.
