Abstract
There is provided a method, a device (), and a system () for enhancing changes in an image () of an image sequence () captured by a thermal camera (). An image () which is part of the image sequence () is received (S) and pixels () in the image that have changed in relation to another image () in the sequence are identified (S). Based on the intensity values of the identified pixels, a function () which is used to redistribute intensity values of changed as well as non-changed pixels in the image is determined (S). The function has a maximum () for a first intensity value () in a range () of the intensity values of the identified pixels, and decays with increasing distance from the first intensity value.
