摘要： Systems and methods provide infrared camera techniques that may improve image quality or infrared camera performance over a range of varying conditions. For example, in accordance with an embodiment of the present invention, a system is disclosed that transforms data provided by an infrared camera based upon environmental conditions at the time the data was obtained. As an example, the image quality provided by the infrared camera may be improved over a range of environmental conditions by the proper transformation of the data based upon the data and/or sensor information.

摘要： Methods and systems for mitigating undesirable video flash in infrared camera systems are disclosed. A frame of video can be stored in a buffer and information related to the frame of video can be processed prior to displaying the video such that the processed information facilitates display of the video substantially without flashing. A display of a non-flashed frame can be frozen while a flash event would otherwise cause a flashed frame to be displayed. The shift in a histogram caused by a flash event or some portion thereof can be subtracted from pixels of an image. Thus, image quality can be substantially enhanced.
摘要翻译：公开了用于减轻红外相机系统中的不期望的视频闪光的方法和系统。视频帧可以存储在缓冲器中，并且可以在显示视频之前处理与视频帧相关的信息，使得处理的信息有助于基本上不闪烁地显示视频。可以冻结非闪光帧的显示，而闪光灯事件否则将导致闪烁的帧被显示。可以从图像的像素中减去由闪光灯事件或其某些部分引起的直方图的偏移。因此，可以显着提高图像质量。

摘要： A method of obtaining a spatial low pass filtered images from the video output of a video camera operable to produce successive video frames in the form of pixelated 2D sensed images. Each of the sensed images has a first predetermined number of rows of pixels and a second predetermined number of columns of pixels. The method may include scanning the sensor array row by row, and deriving the value of each pixel of said low spatial frequency image in such a way that said low spatial frequency value of a pixel is dependent on at least all earlier scanned pixels of the current row and all earlier scanned rows, but is not dependent on the pixels of rows located below a pixel row which is a third predetermined number of rows below the current row, said third predetermined number being significantly less than said first predetermined number.
摘要翻译：从摄像机的视频输出获得空间低通滤波图像的方法，可操作以产生像素化2D感测图像形式的连续视频帧。每个感测图像具有第一预定数量的像素行和第二预定数量的像素列。该方法可以包括逐行扫描传感器阵列，并且以这样的方式导出所述低空间频率图像的每个像素的值，使得像素的所述低空间频率值至少依赖于当前的所有早期扫描的像素行和所有先前的扫描行，但是不依赖于位于当前行下方的第三预定行数的像素行下方的行的像素，所述第三预定数明显小于所述第一预定数。

摘要： An imaging apparatus including an infrared video camera. The infrared video camera includes a sensor array operable to produce successive video images in the form of pixelated two-dimensional images. The imaging apparatus further comprises a processing arrangement operable to reduce or increase the overall brightness of an image in dependence upon the overall brightness of the pre-enhanced image and the overall brightness of the preceding enhanced image, so that the change in the overall brightness (DC-level) between the enhanced image and the preceding enhanced image is decreased.
