1. A method for use in a computerized data processing apparatus configured to process data comprising a sequence of images, the method comprising: for a given image of the sequence of images, determining a temporal latency value associated with one or both of a spatial change or a temporal change relative to one or more images preceding the given image within the sequence of images; wherein: individual ones of the sequence of images comprise a plurality of pixels having a pixel characteristic associated therewith; one or both of the spatial change or the temporal change is determined based on a function of the pixel characteristic between the plurality of pixels of the given image and the plurality of pixels of the one or more images preceding the given image within the sequence of images; the pixel characteristic is based on one or more of a pixel luminance value, a pixel chromaticity value, or a contrast parameter between two pixels; the contrast parameter is determined based on one or both of (i) a difference between a luminance value of individual ones of the two pixels or (ii) a difference between chromaticity values of individual ones of the two pixels; and the temporal latency value is configured insensitive to a parameter determined based on an average luminance of individual ones of the two pixels.
