摘要

PROBLEM TO BE SOLVED: To provide a color bar signal generating system that is compatible with formats of a television signal.;SOLUTION: The color bar signal generator of this invention includes 1st, 2nd and 3rd color bar signal generators that generate color bar signals with an aspect ratio of 16:9 and a color bar signal changeover device that selects an output of the generators. In order to use the color bar signals in common for the aspect ratios of the television screen such as 16:9 (for HD) and 4:3 (for NTSC), the range of 4:3 of the screen is configured by 75% of color bar signals and the outside of the 4:3 range is configured by 100% of color bar signals for the HD.;COPYRIGHT: (C)2001,JPO
