Techniques are disclosed for image output responsive to integration time changes for infrared imaging devices. In one example, a system includes an imaging device configured to capture a first image using a first integration time and a second image using a second integration time different from the first integration time. The system further includes a processing circuit configured to determine the second integration time based at least on content of the first image. The processing circuit is further configured to determine a scale factor for the second integration time based on the first integration time and the second integration time. The processing circuit is further configured to scale the second image by the scale factor. Related methods and devices are also provided.

Image output adjustment responsive to integration time changes for infrared imaging devices

The invention relates to a method for compensating motion blur in connection with vibrations in an image recording apparatus (), such as a camera, for stabilization of recorded images, wherein use is made of a reference image. According to the invention, a frame () of a recorded image is selected for image stabilization and the degree of sharpness () in the selected frame is evaluated and compared () with a previously saved reference value () for the degree of sharpness for a previously selected frame. The last chosen frame is used to update () a video sequence and the degree of the sharpness for the last chosen frame is saved () as a new reference value if the degree of sharpness for the last chosen frame is deemed to be better () than or equally as good as the reference value for the degree of sharpness for a previously selected frame. The reference value () for the degree of sharpness for a previously selected frame is saved with reduction () of the value of sharpness and the previously selected frame is used in the video sequence if the degree of sharpness for the last chosen frame is deemed to be worse () than the reference value for the degree of sharpness for the previously selected frame. As a result of the invention, a method which, by relatively simple action, can effectively compensate for motion blur in connection with vibrations is provided.
