Abstract
The invention relates to an electronic information technology. An image automatic adjustment method based on an RGB sensor comprises the steps that (1) the light RGB color and the intensity of the current environment are sampled, so as to acquire sampling data; (2) the sampling data are smoothened; (3) according to the corresponding relation between the light intensity level and the sampling data, the corresponding current light intensity level is acquired according to the sampling data; (4) according to the corresponding relation between the light intensity level and the backlight brightness, the current backlight brightness is determined; (5) backlight brightness adjustment is carried out according to the current backlight brightness; (6) according to the corresponding table of the RGB color and the sampling data, a corresponding RGB color value is acquired according to the sampling data; (7) a deviation RGB color value is acquired according to the environment light RGB color value; and (8) according to the deviation RGB color value, the RGB color cast of a television is set. According to the invention, under different environment light environments, a user sees a consistent image effect.
Description
Technical field
The present invention relates to electronic information technology, relate in particular to one in digital television machine and digital TV set-top box, by RGB ambient light, according to the color of surround lighting, brightness, TV is carried out to the method for image parameter tune.
Background technology
Surround lighting: claim again bias light, be called for short backlightly, surround lighting is the conventional light that illuminates whole scene.This light has uniform intensity, and belongs to homogeneous diffuse reflection.It does not have recognizable light source and direction.
RGBSensor:RGB color sensor, becomes rgb value by chromatic filter by measured color decomposition, then detects respectively intensity of all kinds by photodiode.
Image model: image model i.e. one group of predefined image parameter, according to actual displayed demand, the parameters such as brightness, contrast, color saturation, tone has been preset to rational numerical value.
Existing TV need to manually arrange video effect conventionally, and trouble of user's input, so practical function is little.
Summary of the invention
Technique effect of the present invention can overcome above-mentioned defect, a kind of image automatic adjusting method based on RGB transducer is provided, it is by detecting color-values and the light intensity value in RGB sensing equipment, automatically adjust display brightness and color colour cast according to ambient light situation, make user under different ambient light environment, watch consistent image effect, reduce the stimulation of light to eyes, increase the comfort level of people in the time televiewing.
For achieving the above object, the present invention adopts following technical scheme: it comprises the steps:
(1) light rgb color and the intensity of current environment are sampled, obtain sampled data;
(2) sampled data is carried out to smoothing processing;
(3) according to the corresponding relation of light intensity grade and sampled data, obtain corresponding current light intensity grade according to sampled data;
(4), according to the corresponding relation of light intensity grade and backlight illumination, determine current backlight brightness;
(5) carry out adjusting backlight luminance according to above-mentioned current backlight brightness;
(6) according to rgb color and the corresponding table of sampled data, obtain corresponding rgb color value according to sampled data;
(7) obtain deviation RGB color value according to surround lighting rgb color value;
(8), according to deviation RGB color value, the RGB colour cast of TV is arranged.
Image automatic regulating apparatus based on RGB transducer of the present invention is dynamically adjusted television image brightness, contrast, color saturation, the isoparametric method of tone, by detecting rgb color and the light intensity value transmitted in RGB transducer, image model is dynamically adjusted.Realize and realize light rgb color and the intensity of current environment are sampled by RGBSensor, obtain sampled data, by sampled data is carried out to smoothing processing, obtain light intensity and rgb color value, according to light intensity and rgb color value to image brightness with partially arrange.By corresponding brightness, contrast, color saturation, the isoparametric value of tone, action is set accordingly, thereby reach automatic adjustment image parameter, for user provides consistent image perception effect, reduce the stimulation of light to eyes, increase the object of the comfort level of people in the time televiewing.
In the time that surround lighting changes, terminal recognition changes to surround lighting, carry out intensity and the identification of rgb color value, adjust brightness, the contrast level parameter in image parameter according to brightness value, adjust the colour cast parameter in image parameter according to RGB colour cast, make user under different ambient light environment, watch consistent image effect, reduce the stimulation of light to eyes, increase the comfort level of people in the time televiewing, and more energy-conserving and environment-protective.
Image automatic adjusting method based on RGB transducer of the present invention, makes user under different ambient light environment, watches consistent image effect, reduces the stimulation of light to eyes, increases the comfort level of people in the time televiewing.
