There is described an image processing method in which a scene is repeatedly imaged to form a series of input images. For at least a subset of the input images, a colour calibration procedure is conducted which populates a foreground colour histogram with the frequency of occurrence of colour values in a stencil area of the input image, and populates a background colour histogram with the frequency of occurrence of colour values outside of the stencil portion of the input image. For at least a subset of the input images, a colour replacement procedure is conducted which updates the stencil area based on a determination, from the colour values of pixels within the input image, of likelihood values representing the likelihood of pixels belonging to an image area of interest, the likelihood value for each colour value being determined from a combination of the foreground and background colour histograms, replaces the original colour values of pixels within the updated stencil area of the input image with replacement colour values, and displays the image on which colour replacement processing has been conducted. In this way, a stencil area is determined based on foreground / background histogramming, and used both to define an area to which colour replacement processing is to be conducted, and also an area for use in further populating the colour histograms to calibrate the colour replacement processing.
