The method that prior art is regulated backlight illumination mainly includes following two kinds of schemes: a kind of is manual adjustments, and promptly the user enters custom menu by telepilot to regulate when needs are regulated backlight illumination; Another kind is to adopt light sensation IC Auto-Sensing environmental light brightness, and system regulates the backlight brightness values that suitable user watches automatically according to the environmental light brightness that detects then.
Yet, the method of the manual adjustments backlight illumination of above-mentioned prior art is not intelligent, though and adopt the method intelligence of light sensation IC detecting, when the close photosensitive region of other object, block easily, influence the light of photosensitive area, thereby cause erroneous judgement, cause mistuning joint backlight illumination, particularly when the people is mobile repeatedly from photosensitive region, backlight will be bright secretly conversion repeatedly, and adopt light sensation IC to regulate backlight illumination itself just to have increased cost.
Summary of the invention
Embodiment of the invention technical matters to be solved be to provide a kind of cost low, avoid the mistuning joint backlight and can intelligence regulate method, system and the televisor of adjusting backlight illumination backlight.
For solving the problems of the technologies described above, the embodiment of the invention provides a kind of method of regulating backlight illumination, said method comprising the steps of:
Set in advance one or more Preset Time sections, and the backlight brightness values of corresponding time period correspondence is set;
The current television signal that decoding receives obtains the current time value;
Judge whether the current time value obtain is in the Preset Time section, if then current backlight brightness values is adjusted to the backlight brightness values of described Preset Time section correspondence.
The embodiment of the invention also provides a kind of system that regulates backlight illumination, and described system comprises:
Module is set, is used to be provided with one or more Preset Time sections, and the backlight brightness values of corresponding time period correspondence is set;
Decoder module, the current television signal that is used to decode and receives obtains the current time value;
Judge module is used to judge whether the current time value that obtains is in the Preset Time section;
Backlight brightness control module, being used for when judging the current time value that obtains is to be in the Preset Time section, then current backlight brightness values is adjusted to the backlight brightness values of described Preset Time section correspondence.
The embodiment of the invention also provides a kind of televisor, and described televisor comprises the system that regulates backlight illumination, and described system comprises:
Module is set, is used to be provided with one or more Preset Time sections, and the backlight brightness values of corresponding time period correspondence is set;
Decoder module, the current television signal that is used to decode and receives obtains the current time value;
Judge module is used to judge whether the current time value that obtains is in the Preset Time section;
Backlight brightness control module, being used for when judging the current time value that obtains is to be in the Preset Time section, then current backlight brightness values is adjusted to the backlight brightness values of described Preset Time section correspondence.
In embodiments of the present invention, utilize the temporal information in the TV signal code stream, judge that real-time time information in the code stream is whether in needs are regulated the Preset Time section of backlight illumination, if then current backlight brightness values is adjusted to default backlight brightness values; Thereby reach the effect of energy-conservation and suitable user's visual custom.
