Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, in a first embodiment of the present invention, a method for controlling a display effect of a television includes the following steps:
step S10, obtaining environment brightness information, and determining the white balance color temperature of the image according to the environment brightness information;
in this step, the ambient brightness information is a brightness value of the current environment, the television can sense the brightness value of the current environment through the light sensor, the light sensor transmits the sensed brightness value of the current environment to a main processor (CPU) of the television, the CPU performs white balance operation on the obtained brightness value of the current environment to obtain a white balance color temperature value of the field environment, and the white balance color temperature value is automatically set to a display effect of the television to meet the color temperature of the field environment.
According to the light sensor, whether the current environment state is bright or dark can be known, when the environment state is bright, the calculated white balance color temperature value is large, and after the white balance color temperature value is set in the display effect of the television, the picture can not be dark; when the environment state is dark, the white balance color temperature value obtained by calculation is small, and after the white balance color temperature value is set in the display effect of the television, the picture looks milder, and the purpose of protecting eyes is achieved.
It should be noted that, in an embodiment of the present invention, the light sensor acquires the brightness value of the current environment in real time, calculates the real-time white balance color temperature according to a change of the brightness value of the environment, and sets the real-time white balance color temperature to the display effect of the television, so that the display effect of the television adapts to human eyes intelligently.
In another embodiment, the image white balance color temperatures corresponding to different environment brightness values may be stored in the television, and after the light sensation sensor acquires the brightness value of the current environment in real time, the inquired image white balance color temperature corresponding to the brightness value of the current environment is set in the display effect of the television. And when the image white balance color temperature corresponding to the brightness value of the current environment cannot be inquired, calculating, and setting the obtained image real-time white balance color temperature into the display effect of the television.
In addition, the calculation amount required for calculating the white balance color temperature of the image in real time according to the environment brightness value is large, so that the memory occupied in the calculation process is large, therefore, an environment brightness change threshold value is preset in the television, when the difference value between the current environment brightness value sensed by the light sensing sensor and the environment brightness value sensed last time is smaller than the environment brightness change threshold value, the current environment brightness value is not calculated, and the image white balance color temperature set in the display effect of the television is not changed.
It can be understood that when the environmental brightness value changes very little, the white balance color temperature of the image set by the current television is directly adopted; and when the change of the ambient brightness value is large, setting the image white balance color temperature calculated according to the ambient brightness value into the display effect of the television.
Step S20, acquiring screen brightness information of the television, and determining an image backlight brightness value according to the environment brightness information and the screen brightness information;
specifically, the acquired screen brightness information includes a maximum brightness of a screen of the television, a minimum brightness of the screen, and a backlight brightness value of a current screen. The maximum brightness of the screen is the maximum brightness which can be adjusted by the television screen; the minimum brightness of the screen is the minimum brightness which can be adjusted by the television screen; the backlight brightness value of the current screen is the backlight value of the screen when the acquisition operation occurs.
In this step, the backlight brightness value of the image is determined by using the screen brightness information and the environment brightness information of the television. For example, when the ambient brightness value is increased, the backlight brightness value determined by combining the screen brightness information is increased, and the backlight brightness value is automatically set to the display effect of the television, that is, the current backlight brightness value of the television is automatically adjusted to a higher value, so that the picture looks brighter; when the environment brightness value is reduced, the backlight brightness value determined by combining the screen brightness information is reduced, and the backlight brightness value is automatically set to the display effect of the television, namely, the current backlight brightness value of the television can be automatically adjusted to a lower value, so that the picture looks milder.
In an embodiment, different environment brightness information and image backlight brightness values corresponding to screen brightness information of the television can be stored in the television, and after the obtained current environment brightness value and the obtained backlight brightness value of the current screen, the inquired image backlight brightness value corresponding to the environment brightness information is set in the display effect of the television. And when the image backlight brightness value corresponding to the brightness value of the current environment and the backlight brightness value of the current screen cannot be inquired, calculating, and setting the obtained image backlight brightness value into the display effect of the television.
In addition, the calculation amount required for calculating the image backlight brightness value according to the environment brightness information and the screen brightness information is very large, which results in more memory occupied in the calculation process, then an environment brightness change threshold and a screen backlight brightness change threshold are preset in the television, when the difference value between the current environment brightness value sensed by the light sensor and the environment brightness value sensed at the last moment is smaller than the environment brightness change threshold, and the difference value between the backlight brightness value of the current screen and the backlight brightness value of the screen at the last moment is smaller than the screen backlight brightness change threshold, the environment brightness information and the screen brightness information are not calculated, and the image white balance color temperature and the image backlight brightness value set in the display effect of the television are not changed.
It can be understood that when the ambient brightness value and the backlight brightness value of the current screen both change very little, the image white balance color temperature and the image backlight brightness value set by the current television are directly adopted; when the ambient brightness value or the backlight brightness value of the current screen is changed greatly, the image white balance color temperature and the image backlight brightness value are calculated according to the ambient brightness information and the screen brightness information, and are set to the display effect of the television.
Therefore, the backlight of the television is automatically adjusted by utilizing the screen brightness information in combination with the environment of the television, the adjustment process of the backlight brightness can be completed without manual operation of a user, the intelligent dynamic adjustment of the television backlight is realized, and the backlight brightness value with the optimal viewing effect is obtained.
Step S30, acquiring film source brightness information, and determining an image brightness response curve according to the film source brightness information, the environment brightness information and the screen brightness information;
specifically, the slice source luminance information in the present embodiment is a histogram of the current signal pattern of the slice source. According to the histogram of the current signal pattern effect of the film source, the state of the current signal pattern effect can be obtained, for example, whether the current signal pattern is a black lens pattern, an ice and snow pattern, a bright sun and high illumination pattern or the like is identified, that is, whether the current signal pattern effect is a bright pattern or a dark pattern is identified. And determining an image brightness response curve through the identified state of the current picture, the bright picture ratio, the dark picture ratio, the ambient brightness information and the screen brightness information.
In one embodiment, an image brightness response curve corresponding to different film source brightness information, environment brightness information and screen brightness information can be stored in a television, the obtained image brightness response curve is directly searched, and the image brightness response curve is set in a display effect of the television; or pre-storing different image brightness response curve generation parameters corresponding to the film source brightness information, the environment brightness information and the screen brightness information, and generating an image brightness response curve according to the generation parameters. And when the image brightness response curve corresponding to the film source brightness information, the environment brightness information and the screen brightness information cannot be inquired, obtaining the image brightness response curve through calculation, and setting the image brightness response curve into the display effect of the television.
Therefore, different image brightness response curves are obtained according to different film source brightness information, environment brightness information and screen brightness information, and the image brightness response curves are set in the display effect of the television, so that different film source pictures correspond to different brightness response curves, and the display effect of the television is better adapted to the requirements of human eyes while the display effect is improved.
It should be noted that there is no running precedence relationship among steps S10, S20, and S30, that is, the ambient brightness information, the brightness information of the screen, and the brightness information of the film source are acquired at the same time, and then the white balance color temperature of the image, the brightness value of the backlight of the image, and the image brightness response curve are obtained at the same time through respective calculation of the three kinds of information, and then step S40 is performed.
In step S40, the image white balance color temperature, the image backlight brightness value and the image brightness response curve are set to the display effect of the tv.
In this embodiment, the image white balance color temperature, the image backlight brightness value and the image brightness response curve of the television are calculated and obtained through the acquired environment brightness information, the screen brightness information and the film source brightness information of the television, and the image white balance color temperature, the image backlight brightness value and the image brightness response curve of the television are automatically set to the display effect of the television, so that the final display effect of the television is intelligently adapted to human eyes, the display effect of the television is automatically adjusted, and the optimal viewing effect is displayed while the human eyes are protected.
Further, referring to fig. 2, based on the first embodiment, in the second embodiment of the present invention, the step S20 includes:
step S21, acquiring the maximum brightness of the screen of the television, the minimum brightness of the screen and the backlight brightness value of the current screen;
step S22, calculating a brightness conversion coefficient according to the maximum brightness of the screen of the television and the minimum brightness of the screen of the television;
step S23, calculating an environment conversion coefficient according to the environment brightness information and the backlight brightness value of the current screen;
in step S24, an image backlight luminance value is calculated according to the environment luminance information, the environment conversion coefficient, and the luminance conversion coefficient.
It should be noted that the luminance conversion coefficient is a ratio of the maximum luminance of the screen of the television to the minimum luminance of the screen; the environment conversion coefficient is the ratio of the brightness value of the current environment to the backlight brightness value of the current screen. The maximum brightness and the minimum brightness of the screen of the same television are fixed values, the brightness conversion coefficient is not changed, and the environment conversion coefficient is dynamically changed according to the difference between the acquired brightness value of the current environment and the backlight brightness value of the current screen.
Specifically, if the environment becomes bright, that is, the current environment brightness value increases, the environment state conversion coefficient increases, and the image backlight brightness value calculated according to the environment brightness information, the brightness conversion coefficient and the environment conversion coefficient is larger; when the environment is dark, that is, the current environment brightness value is reduced, the environment state conversion coefficient is reduced, and the image backlight brightness value calculated according to the environment brightness information, the brightness conversion coefficient and the environment conversion coefficient is smaller.
Further, referring to fig. 3, in a third implementation of the present invention based on the first embodiment, the step S40 specifically includes:
step S50, determining whether the calculated backlight luminance value of the image is greater than a preset first backlight luminance threshold value;
in step S41, if yes, the image white balance color temperature, the first backlight brightness threshold and the image brightness response curve are set to the display effect of the television.
Step S51, if not, determining whether the calculated backlight brightness value of the image is smaller than a preset second backlight brightness threshold value;
in step S42, if yes, the image white balance color temperature, the second backlight brightness threshold and the image brightness response curve are set to the display effect of the television.
A first backlight brightness threshold value and a second backlight brightness threshold value of an image are prestored in the television, wherein the first backlight brightness threshold value is larger than the second backlight brightness threshold value. The first backlight brightness threshold value can be the maximum backlight brightness value to which the image can be adjusted, or the backlight brightness value which is set by the user and is suitable for the viewing requirement of the user; the second backlight brightness threshold may be a minimum backlight brightness value to which the image can be adjusted, or a backlight brightness value set by the user to adapt to the viewing requirement of the user.
Specifically, in an embodiment, by determining whether the calculated backlight brightness value of the image is greater than a preset first backlight brightness threshold, when the calculated backlight brightness value of the image is greater than the first backlight brightness threshold, the first backlight brightness threshold is used to replace the calculated backlight brightness value of the image, that is, the white balance color temperature of the image, the first backlight brightness threshold and the image brightness response curve are set in the display effect of the television, so that the display effect of the television meets the user requirement, protects the human eyes and achieves the best viewing effect.
In another embodiment, it may be further determined whether the calculated backlight brightness value of the image is smaller than a preset second backlight brightness threshold, and when the calculated backlight brightness value of the image is smaller than the second backlight brightness threshold, the second backlight brightness threshold is used to replace the calculated backlight brightness value of the image, that is, the white balance color temperature of the image, the second backlight brightness threshold and the image brightness response curve are set in the display effect of the television, so that the display effect of the television meets the user's requirements, protects the human eyes and achieves the best viewing effect.
In an embodiment, it may further be determined whether the calculated backlight brightness value of the image is greater than a preset first backlight brightness threshold, if not, then it is determined whether the calculated backlight brightness value of the image is less than a preset second backlight brightness threshold, and if so, the white balance color temperature, the second backlight brightness threshold, and the image brightness response curve are set to a display effect of the television; if not, setting the image white balance color temperature, the calculated image backlight brightness value and the image brightness response curve into the display effect of the television.
It is understood that the image white balance color temperature, the calculated image backlight brightness value and the image brightness response curve are set into the display effect of the television only if the calculated backlight brightness value of the image is less than the first backlight brightness threshold and greater than the second backlight brightness threshold.
In the embodiment, the backlight of the television is automatically adjusted by combining the screen brightness information with the environment information of the television, the adjustment process of the backlight brightness can be completed without manual operation of a user, the intelligent dynamic adjustment of the backlight of the television is realized, and the backlight brightness value with the best viewing effect is obtained.

step S31, acquiring a histogram of the current signal pattern effect of the film source;
step S32, calculating the average brightness of the picture according to the histogram of the current signal effect;
step S33, calculating the average image level according to the histogram of the current signal image effect and the average brightness of the image;
in step S34, an image luminance response curve is calculated according to the average image level, the ambient luminance information, the maximum luminance of the screen of the television, and the luminance conversion coefficient.
It is to be understood that the slice source luminance information refers to a histogram of the current signal pattern of the slice source. And calculating the average brightness of the picture according to the histogram of the current signal image effect of the picture source so as to obtain the brightness degree of the picture. Calculating an average image level according to the histogram of the current signal image effect and the average brightness of the picture, wherein the average image level is high, which means that most of the images have brightness components, namely, the bright picture occupation ratio of the picture is high; conversely, a low average image level means that the area of the image occupied by black becomes large, that is, the dark picture occupancy of the picture is high.
In this embodiment, a luminance response curve is calculated according to the average image level, the ambient luminance value, the maximum luminance of the screen of the television, and the luminance conversion coefficient, and the luminance response curve is set in the display effect of the television, which is equivalent to fine adjustment of the original luminance response curve, so that the viewing effect of the display effect of the television is improved, and eyes of people are protected.
