Problems solved by technology
For this reason, there is a disadvantage in that the video display apparatus is not suitable for a detailed picture quality correction corresponding to an audio-visual environment of a user.
In the case in which morning, afternoon and night are decided based on the time information, it is impossible to uniquely determine the audio-visual environment of the user depending on a change in a time for a sunset due to a season or a latitude of a position in which the video display apparatus is to be disposed.
Therefore, there is a disadvantage in that the video display apparatus is not suitable for the detailed picture quality correction.
