Patent ID: 8687043

Claim:
A method of generating a stereoscopic image signal, the method comprising: receiving a left-eye image signal and a right-eye image signal with a multiplexer; generating a progressive stereoscopic image signal by multiplexing the left-eye image signal and the right-eye image signal with the multiplexer by multiplexing the left-eye image signal and the right-eye image signal such that scanning lines of the left-eye image signal and scanning lines of the right-image signal are alternately arranged; and scaling up or down the generated progressive stereoscopic image signal by vertically scaling with a vertical scaler and horizontally scaling with a horizontal scaler the generated progressive stereoscopic image signal, and by interpolating between consecutive scanning lines of the left-eye image signal and interpolating between consecutive scanning lines of the right-eye image signal to generate alternately arranged intermediate scanning lines of the left-eye and right eye signals, wherein the progressive stereoscopic image signal is generated before the scaling up or down of the generated progressive stereoscopic image signal.
