Abstract

A picture converting system that can fit input signals to a wide-aspect (16:9) display without jitter and skew was developed. The architecture of the converter and a LSI for its hardware implementation are described. In this system, the compression and enlargement for converting the image were done only by the digital signal processing circuits, and some new methods that were suitable for this digital signal processing system were adopted. This system also included features for minimizing the difference of the luminescence decay of a phosphor between the center and the side portions of the display
