DISPLAY METHOD AND APPARATUS

The present disclosure relates to a controller for generating a composite image (IMG) of a region behind a towing vehicle (V). The controller is operable to receive a towing vehicle image data (DV) from a towing vehicle camera (C); and a trailer image data (DV) from a trailer camera (C). The controller combines the towing vehicle image data (DV) and the trailer image data (DV) to generate a composite image data (DV) corresponding to a composite image (IMG). The controller is operable to output the composite image data (DV). The controller is operable selectively to enable and/or disable the output of the composite image data (DV). The controller is configured to monitor a status of a turn signal indicator. The controller is configured to disable the output of the composite image data (DV) when the turn signal indicator is activated; and/or enable the output of the composite image data (DV) when the turn signal indicator is de-activated.
