Embodiment one
Referring to Figure 1, it illustrates a kind of a kind of flow chart of 3D TV self-adaptation control method provided by the invention, packetsIt includes:
Step 101, smart television obtains the light intensity information of ambient enviroment light；
In the present embodiment, smart television built-in ambient light sensor, external ambient light sensor or can pass through theThree method, apparatus obtain surrounding light characteristics.Ambient light sensor can pass through phototransistor, photo resistance or photosensitive twoPole pipe is realized.
Step 102, smart television adjusts 3D effect according to light characteristics；
In the present embodiment, after the light characteristics of smart television acquisition ambient enviroment, including light intensity information, according to lightLine strength information adjusts 3D effect, is specifically as follows, and adjusts TV brightness according to light intensity and contrast is arranged, to eliminateLuminance difference between picture and environment.
Specifically, theoretical based on the Retinex that color constancy theory proposes, the present invention also proposes a kind of adaptive " stars "Enhance algorithm, using the luminance component and reflecting component of Retinex theory separate picture, adaptive " star is carried out to luminance componentOccasion " correction, finally restores the details and color of image using reflecting component.
Step 103, smart television shows the 3D effect adjusted by screen.
In the present invention, smart television can be automatically based upon the light intensity information of ambient enviroment light, automatically adjustDisplay effect significantly improves the visual enjoyment of user.
Embodiment two
Adaptive " stars " enhancing algorithm specific implementation mentioned in above-described embodiment one is as follows:
Step 201, smart television obtains the light intensity information of ambient enviroment light；
Specifically, light intensity information can be obtained by the ambient light sensor of smart television, it is then sent to intelligent electricityDepending on CPU.
Step 202, smart television detects the successive frame of image to be shown；
In embodiments of the present invention, the essence of successive frame is the film for continuously transmitting picture, such as 60Hz, just with 120HzSpeed send every frame image, every frame alternately displays out, successively receives for left/right eye.Smart television can be according to userThe title of the program of program request or live streaming determines the successive frame of the image of the program.
Step 203, the successive frame that smart television will test is decomposed, and reflecting component and luminance component are formed；
In embodiments of the present invention, each channel brightness having the same of successive frame I (x, y), it may be assumed that I (x, y)=R (x,Y) * L (x, y), wherein R (x, y) indicates the reflecting component in each channel；The luminance component of L (x, y) expression successive frame.In general,Using the maximum value in successive frame channel as the illumination V (x, y) of eye-observation, specifically, V (x, y)=Max I (x, y).To V (x,Y) Fourier's variation is carried out, then carries out process of convolution, the luminance component of available successive frame, it may be assumed that L (x, y)=G (x, y) * V(x, y).
Step 204, smart television carries out self-adaptive processing to the luminance component of successive frame；
In embodiments of the present invention, output brightness is to carry out self-adaptive processing for the luminance component of successive frame, it may be assumed that outputBrightness=L (x, y) * self-adaptive processing parameter.Wherein, self-adaptive processing parameter is got by light intensity information, specifically: intelligenceTelevision internal presets light intensity information table corresponding with self-adaptive processing parameter, and different light intensity informations is correspondingDifferent self-adaptive processing parameters, for example, in daily life, the light intensity at night are as follows: 0.001-0.02 Lux；MonthThe light intensity at night are as follows: 0.02-0.3 Lux；Cloudy day indoor light intensity are as follows: 5-50 Luxs；Cloudy outdoor lightLine intensity are as follows: 50-500 Luxs；The indoor light intensity of fine day are as follows: 100-1000 Luxs；For under varying environmentDifferent auto-adaptive parameters is arranged in light intensity, the value of the luminance component, i.e. brightness is determined according to self-adaptive processing parameter, reallyThe luminance component for protecting successive frame changes with the variation of smart television ambient enviroment light.
Step 205, the luminance component of the successive frame after smart television is to self-adaptive processing is carried out is synthesized with reflecting component,Generate output adaptive successive frame adjusted.
In the present embodiment, smart television obtains the light intensity information of ambient enviroment light, according to light intensity informationThe luminance component of successive frame is handled, it is ensured that the 3D effect of smart television and the environments match of surrounding improve user experience.
Further, the normal visual angle angle of common people is about 40 ° of the angle of depression, and in this angle, the eye protection to people isIt is best, by the adjustment to smart television height, reach the adjustment of the visual angle angle to human eye and smart television, Ke YidaTo the protection to eyes.The present invention may further include:
Step 206, smart television scans to obtain the human body image of user by camera；
Step 207, human face region present in smart television detection human body image；
Step 208, smart television determines that there are eye features in human face region；
Specifically, can use the image section that face recognition algorithms calculate eyes in human face region.Preferably, faceRecognizer can use edge detection method.
Step 209, according to the region in the region of face eyes and camera of smart television, the viewing angle of active user is calculatedDegree；
Specifically, the camera of smart television can be referential according to the spatial position of itself, eyes of user is calculatedRelative angle, specifically, smart television can be with a preset standard value, by comparing the opposite position of human eye when factoryIt sets, determines the angle of active user's viewing.
Step 210, the viewing angle current according to user is adjusted to 40 ° of the angle of depression.
In embodiments of the present invention, lifting device is housed, which can be set in smart television on smart televisionLower part or back；Can by lifting device, for example, gear or screw etc., adjust smart television it is vertical onLower height, it is ensured that in the case where user watches TV position and do not move, the height of TV is adjusted, so that the sight of TV and userShadow angle reaches optimal viewing angle, for example, 40 ° of the angle of depression.
Specifically, smart television judge the viewing angle of active user for 0 degree, i.e. the eye-level and smart television of userCamera height it is concordant, then can by the CPU of smart television control lifting device reduce TV height, until userThe angle of eyes and until the viewing angle of smart television reaches suitable angle, for example, 40 ° of the angle of depression
Smart television of the embodiment of the present invention can intelligence adjustment user viewing angle, it is ensured that eyes obtain lesser woundEvil.
