A method introduces the notion of a quality / energy tradeoff control for visual contents allowing to provide increased energy reduction compared to the spatially alternating complementary colors or temporally alternating complementary colors processing algorithms, at the cost of a decrease in terms of quality of experience. It is proposed to allow the user to control the balance between energy consumption reduction and quality of experience via the use of an algorithm strength parameter. Algorithm strength is a parameter in the algorithm performing the energy reduction on the video images, such that, depending on its value, different and continuous energy reduction levels are reached, and a corresponding quality of experience is obtained. More precisely, when using the alternating complementary colors algorithms, the algorithm strength will determine the radius of a color similarity volume that will define the size of the search space for a pair of replacement colors.

The method and device enable reducing the energy required to render an image by replacing pixels of the image with temporally consecutive pixels of alternating complementary colors that require less energy to display and are selected according to a polarity constraint. This solution exploits the flicker fusion property of the human visual system, which allows selecting complementary colors that can visually have the same perceptual properties as corresponding monochrome colors. The alternating complementary colors are selected to be more economical in terms of the energy consumption required to render the colors. This replacement is performed by either frame doubling, frame skipping, or frame averaging. The concept of consecutive pixels is temporal. In other words, when using frame doubling, one pixel is replaced by two temporally consecutive pixels of alternating complementary colors, with the replacement pixels having half the duration. When using frame skipping or averaging, two temporally consecutive pixels are replaced by two temporally consecutive pixels of alternating complementary colors, with the replacement pixels having the same duration. The polarity constraint enables a reduction in perceived flicker. The association between colors and corresponding alternating complementary colors can be obtained from a lookup table. These principles can be used for videos containing an image or a sequence of images.
