Abstract:
An integrated circuit comprises deflicker unit is described for adaptively applying deflicker filtering to image data to be displayed using an interlaced scan line technique. The deflicker unit comprises analysis unit arranged to receive the image data and identify at least one region of an image to which deflicker filtering is to be applied, and filter arranged to apply deflicker filtering to those regions identified by the analysis unit. In one example, the analysis unit may be arranged to identify regions of the image to which deflicker filtering is to be applied based at least on energy levels for a high frequency range component within the vertical frequency domain of the image data.
