Abstract: A network of photovoltaic strips positioned in front of an image causes a decrease in the luminosity of said image, which is not uniform for all of the colours and causes an optical moiré phenomenon that is perceived by the observer when they change their viewing angle. In order to rectify said decrease in visual quality of the image, the invention describes a suitable positioning and dimension of the photovoltaic strips in relation to the inter-pixels of the image.
