1. A method for controlling imaging artefacts during a frame-changeover from a current frame to a following frame displayed by a display device comprising a plurality of pixels, said method comprising the step:
reducing the artefacts by overdriving at least one control signal for controlling the pixel intensity of the related pixel during a frame-changeover, wherein overdriving comprises the steps of:
determining a relative overdrive value for the current frame in dependence of a magnitude of an intensity step between a designated start intensity value of the pixel within the current frame and a designated target intensity value of the pixel within a following frame, wherein the magnitude of the overdrive is based on a set of predetermined overdrive magnitudes, said predetermined overdrive magnitudes being stored in a first memory,weighting the magnitude of the overdrive by a predetermined overdrive weighting factor or predetermined overdrive weighting function, said predetermined weighting factor or predetermined overdrive weighting function being based on a human visual perception system, wherein the predetermined overdrive weighting factor or overdrive weighting function is stored in a second memory,determining an overdrive value in dependence of a magnitude of an intensity step between a currently reached intensity value of the pixel within the current frame and the designated target intensity value of the pixel within the following frame, anddetermining an overdrive intensity value of the control signal in dependence of the predetermined target intensity value, the overdrive value, and the relative overdrive value,wherein the overdrive for the following frame is carried out in dependence of a prediction of the actual pixel intensity value reached at the beginning of the following frame. |
