IMAGE RATE INCREASING

摘要

An image rate increasing device, comprising a low-pass filter (LPF) coupled to receive an input signal (I) to provide a low-pass filtered signal (LP), a mixer (S2) for mixing the low-pass filtered signal (LP) and the input signal (I) to obtain a first output signal (B) with a mixing factor (a) depending on the input signal (I), and a sharpening filter (?l) coupled to receive the input signal (I) for obtaining a second output signal (A). This image rate increasing device is advantageously used in a display device that further comprises a display unit for sequentially displaying the first (B) and second (A) output signals.
