Abstract

A method, apparatus and computer program are provided for reducing the effect of electromagnetic noise on images displayed by a television display (101). A camera (100), when directed towards the display (101), generates image data representing at least a portion of an image being displayed. The image data are analysed by a controller (102) to identify a presence, in the at least a portion of an image being displayed, of one or more in a predetermined set of image artefacts known to result from the presence of electromagnetic noise. Filter characteristics are determined, for use by a configurable filter (104) in the television, corresponding to an identified image artefact. The generated signals are sent to the configurable filter (104) to implement the determined filter characteristics, thereby to reduce the presence of the identified image artefact. The process may be operated iteratively to improve the image quality.
