Zusammenfassung:	A method of generating a de-interlacing filter comprises: analysing a pixel array comprising an interlacing pattern of pixels. The interlacing pattern of pixels comprises first and second pluralities of pixels configured to be read during a first measurement subframe and a second measurement subframe, respectively. An n-state representation of the interlacing pattern of pixels is generated (200) and distinguishes between the first plurality of pixels and the second plurality of pixels. The n-state representation of the interlacing pattern is translated (202) to a spatial frequency domain, thereby generating a spatial frequency domain representation of the n-state representation of the interlacing pattern. A DC signal component is then removed (204) from the spatial frequency domain representation of the n-state representation of the interlacing pattern, thereby generating a DC-less spatial frequency domain representation. A kernel filter is then selected (206) and configured to blur before convolving (208) the DC-less spatial frequency representation with the selected kernel filter.
