An IR camera (1) for use within a predetermined scene temperature range comprises a focal plane array (7), and a signal processing device (9) arranged to receive an incoming signal from pixels of the focal plane array (7). The signal processing device (9) is arranged, for each image, to perform the following steps; identify any pixels of the focal plane array (7) for which the incoming signal, anywhere inside the scene temperature range, is equal to or larger than the predetermined maximum value, or equal to or less than the predetermined minimum value, replace the value of each element thus identified with a replacement value based on the value of at least one neighbouring element. By performing this in real time instead of permanently disabling any element that reaches the maximum or minimum value within the scene temperature range of the camera, the quality of the image is improved.
An IR camera (1) comprising a focal plane array (7), said focal plane array (7) comprising an array of elements for registering incoming IR radiation from an object, and a signal processing device (9) arranged to receive an incoming signal from each element indicative of the incoming IR radiation in said elements, said incoming signal having a predetermined minimum value and a predetermined maximum value, and to process said incoming signal from each of the elements to obtain a temperature value in order to generate a thermal image of the object, said camera (1) having a predetermined scene temperature range and being characterized in that said signal processing device (9) is arranged, for each image, to perform the following steps
A method for use with an IR camera having a predetermined scene temperature range and having a focal plane array comprising a plurality of pixels, for registering incoming IR radiation from an object, said method comprising the steps of
