摘要： Techniques for facilitating temperature compensation are provided. In one example, an infrared imaging system includes a focal plane array configured to capture radiation from a scene and generate image data based on the radiation. The focal plane array further captures radiation from an element associated with the infrared imaging system during capture of the radiation from the scene. The infrared imaging system further includes a temperature sensor configured to determine a temperature of the focal plane array. The infrared imaging system further includes a processing circuit configured to determine a temperature associated with the element based on the temperature of the focal plane array. The processing circuit is further configured to determine a temperature associated with an object in the scene based on the infrared image data, the temperature associated with the element, and the temperature of the focal plane array. Related devices and methods are also provided.

摘要： The present invention is directed to a method for determining a dark signal for each pixel of an image sensor (10), wherein the image sensor (10) comprises multiple pixels, comprising the steps of
- providing a dark pixel response (18) for different image sensor temperatures (16) and for different integration times (14) for each pixel of the image sensor (10),
- determining coefficients of a model for the dark signal for each pixel based on the provided dark pixel response (18),
- determining the dark signal for each pixel for a given integration time (14) and a given image sensor temperature (16) based on the model for the dark signal,
wherein the dark signal of the model is dependent on integration time (14) and on image sensor temperature (16),
wherein the dark signal of the model has a linear dependency on integration time (14),
and wherein a gain (22) and an offset (24) of the linear dependency are dependent on image sensor temperature (16).
Furthermore, the present invention is directed to a method for determining a relative dark signal for each pixel of an image sensor (10).
Further, the present invention is directed to a method for correcting raw image data (32) of an image sensor (10) for dark signal non-uniformity.

摘要： Various techniques are disclosed to provide for detection of temporally anomalous flickering pixels. In one example, a method includes capturing, by a thermal imager of an imaging device, a plurality of thermal images in response to infrared radiation received from a uniform black body, wherein the thermal images comprise a plurality of pixels having associated pixel values. The method also includes determining, for each pixel, a standard deviation of the associated pixel values for the thermal images. The method also includes comparing the standard deviations with a threshold. The method also includes identifying a subset of the pixels as temporally anomalous pixels in response to the comparing. Additional methods, devices, and systems are also provided.
