METHOD FOR ADJUSTING IMAGE PICTURE OF TV

摘要

Instead of adjusting video image conditions - contrast, brightness, color tint mode, etc. - at the every power-on time, properly adjusted results are stored in advance and enables the user to choose the best picture mode with convenient key strokes. A key matrix (K) comprises of the picture adjust keys such as a contrast and brightness key, etc., and adjustment volume keys and a store key. A microcomputer (MC) has an EEPROM type non-volatile storage unit to store adjustment results and generates control signals to input key signals from the remocon and character control of the character generator (OSD). A character generator (OSD) synthesizes character signals with the video adjustment input signals.
