摘要:
A surrounding light judging method and a video compensation control apparatus which are capable of securing an optimum quality of picture by detecting a color signal near a video displaying instrument, judging a lighting environment from the detected color signal, and automatically correcting a video data in accordance with the judged lighting environment and a variation in the lighting environment. The method includes the steps of detecting a first color component and a second color component from a surrounding light, and judging a kinds of the light using the first and second color components
摘要:
A method and apparatus for automatically compensating a tone color. The method includes a first step for determining whether a channel is modified or an input audio signal is switched, a second step for calculating frequency characteristics of the input audio signal and comparing the compared result with data in a basic table, a third step for determining the input audio signal as a least error mode during the second step, and a fourth step for compensating a tone color in accordance with the determined mode. The method and apparatus automatically adjusts a tone color by determining a present tone color in itself on the ground of the frequency energy being presently applied when a channel is modified, an input audio signal is switched, or a color sound mode is modified, thereby eliminating a manual manipulation by a user as well as providing an optimal sound.
