The Plasma AI (Adaptive brightness Intensifier) circuits analyze the video program level for the distribution of dark and bright components. The upper and lower eight bit video signals are memorized into two Plasma AI processors IC9651 and IC9601. The Plasma AI circuits converts the 8 bit signal data to 10 bit signal data. The Flash memories contain the algorithms for the AI circuit. Two AI processors are used to speed up the scanning process and control the number of sustain periods. This increases the brightness and improves the contrast ratio.
