The double line addressing method can be applied to matrix displays with the purpose of effectively decreasing the time necessary for line addressing. In this system, two neighboring lines are addressed simultaneously and receive the same data, which leads to considerable decrease of image sharpness. In order to overcome this problem, the image can be pre-processed by the algorithm described in this application. This algorithm is based on the ability of the human eye to merge quick signals. Namely, when the double line addressing system is applied, the viewer cannot see the odd and even frame separately due to the quick frame change, but their average. The goal of the presented idea is to change the incoming information in such a way that the average image corresponds to the original image as much as possible
