The intelligent television monitors the intensity of external environment light in real time and adaptively adjusts the theme mode of the intelligent television. The process of recognizing the intensity of the external environment light needs to pass through a front-mounted light sensor which is generally fixed at a fixed position of the smart television, and the light sensation value of the external environment is obtained and transmitted to the controller. However, the television device is generally located at one corner of the room, and in most cases, the light sensation value collected by the front light sensor is in direct proportion to the intensity of the whole indoor ambient light, so that the change of the whole indoor ambient light can be objectively shown.
However, the front-end light sensor only collects the light intensity of one indoor angle, and when an invalid scene occurs, misjudgment on ambient light can be caused, so that the display brightness of the smart television is flickering. The invalid scene means that the whole ambient light does not change suddenly, and an obstacle exists to block the front-mounted light sensor, for example, a pedestrian passes through. The effective scene refers to the sudden change of the whole ambient light, such as turning off the light at night and turning the external natural light from clear to cloudy.
In order to avoid the invalid scene causing the display of the smart television to be dim, as shown in fig. 5, in some embodiments of the present application, a display device 200 is provided, which includes a display 260 and a controller 250, and the display 260 has a front sensor unit 231 thereon. The pre-sensor unit 231 may belong to the detector 230.
The front sensor unit 231 includes a light sensor and a distance sensor; the optical sensor is used for acquiring the light sensation value of the environment where the display equipment is located in real time; the distance sensor is used for acquiring the distance between a front object and the display equipment in real time. The real sensor unit acquires different data in real time according to a preset acquisition interval; the preset collection interval for collecting the light sensitivity values may be different from the preset collection interval for the collection distance.
In some embodiments, the light sensor may be an ambient light sensor, an infrared light sensor, a sunlight sensor, an ultraviolet light sensor, or the like, and the ambient light sensor is generally used in the field of display devices and the like to obtain a light sensation value of the environment.
In some embodiments, the distance between the front object and the display device may be obtained by a distance measuring sensor, or may be obtained indirectly by other sensors, such as an infrared sensor, and the distance between the front object and the display device is obtained by an intermediate value of the measurement.
The duration of the ineffective scene is generally shorter, and the duration of the change of the light sensation value of the effective scene is longer. The controller is configured to acquire light sensation values collected by the ambient light sensor in real time, and judge whether the ambient light changes suddenly by judging whether the light sensation values of two adjacent times meet the theme mode adjustment requirement.
In some embodiments, for whether the light sensation values of two adjacent times meet the theme mode adjustment requirement, a first light sensation value and a second light sensation value adjacent to each other in the environment are sequentially obtained; and when the first light sensation value belongs to the high light ray area, the second light sensation value belongs to the low light ray area or the first light sensation value belongs to the low light ray area and the second light sensation value belongs to the high light ray area, judging that the first light sensation value and the second light sensation value meet the theme mode adjustment requirement.
And a transition area is also arranged between the high light area and the low light area. The light value of the high light area is higher than that of the transition area; the light value of the low light area is higher than that of the transition area. By a predetermined high light value LhighAnd low light value LlowTwo threshold values are used to divide the high light area, the low light area and the transition area, wherein the high light value LhighGreater than the low light value Llow(ii) a When the light sensation value is greater than the high light ray value LhighThe current light is bright and belongs to a high light area; when the light sensation value is less than the low light value LlowThe current light is weak, and belongs to a low light area; when the light sensitivity value is at a high light ray value LhighAnd low light value LlowWhen the acquired light sensation value falls in the transition area, the change of the ambient light is not judged; by setting the transition region, the light sensitivity value is prevented from being jittered near the transition region to cause a change of brightness of the display device when the display device is displaying, for example, a situation of brightness flicker, etc. when the lamp is turned on or off, the lamp is turned on or off.
When the light sensation values of two adjacent times meet the theme mode adjustment requirement, the environment light is judged to have sudden change, and when the duration time of the sudden change is longer than the preset time, the light sensation value at the moment is temporarily judged to be changed into an effective scene.
In some embodiments, when an obstruction appears to be blocked around the display device for a long time, the above temporarily determined effective scene may also appear, and then further determination needs to be performed in combination with the distance between the front object and the display device. The controller is configured to acquire a distance acquired by the distance sensor, and when the distance is greater than a preset distance, it is considered that no obstruction blocks the acquisition of the light sensation value of the display device, that is, it is further determined that the change of the light sensation value is an effective scene.
When the distance is smaller than or equal to the preset distance, the distance from the front object to the display device is considered to be too close, the light sensation value collected by the light sensor of the display device can be considered to be changed due to the fact that the light sensation value is shielded by the shielding object, the scene is an invalid scene, the intensity of real ambient light is not changed, and the theme mode of the display device cannot be adjusted.
And after two conditions that the duration of the sudden change is longer than the preset time and the distance is longer than the preset distance are met, more accurately judging the theme mode needing to be switched of the display equipment. At this time, the current theme mode is obtained through the light ray area corresponding to the second light sensation value, and the theme mode of the display device is switched to the current theme mode. The original theme mode is obtained in the area of the light corresponding to the first light sensitivity value and is different from the current theme mode, and the theme mode comprises a dark mode and a light mode; different theme modes correspond to different image quality parameters and theme colors. Through the judgment of the two conditions, the misjudgment probability of the change of the ambient light is reduced, and the user experience is effectively improved.
In some embodiments, currently, as shown in fig. 6, when a front camera 232 is included on the display device, the front camera may belong to the detector 230. In order to further accurately determine the ambient light variation, the determination may be further performed by a front camera 232 according to a selection or a setting of a user, the front camera 232 is configured to take a picture of an environment where the display device is located, and after the step of meeting that the duration of the abrupt change is greater than a preset time and the distance is greater than a preset distance, the controller is further configured to: acquiring the brightness of the picture shot by the front camera 232; judging a current theme mode corresponding to the environment where the display equipment is located according to the comparison of the brightness and the preset brightness, wherein the current theme mode is a bright mode when the brightness is greater than the preset brightness, and the current theme mode is a dark mode when the brightness is less than or equal to the preset brightness; and if the current theme mode is different from the original theme mode, switching the theme mode of the display equipment into the current theme mode.
The judgment of the light in the shooting environment by the front-facing camera 232 can be more accurately carried out, so that the judgment of the change of the ambient light can be more accurately obtained, and the accuracy of the change of the ambient light can be improved. For the picture taken by the front camera 232, the brightness of the picture can be obtained by weighting and averaging each point in the picture, and can also be obtained by other prior arts.
In some embodiments, if the display device does not include the front-facing camera 232, or the user does not want to be shot with excessive privacy, the user experience is effectively improved by reducing the false determination probability of the ambient light change through the determination that the duration of the sudden change is longer than the preset time and the distance is longer than the preset distance.
As shown in fig. 7, the detector 230 may include a front sensor 231 and a front camera 232, data collected by the front sensor 231 and the front camera 232 is transmitted to the controller 250, and the controller 250 determines to control the switching of the theme mode of the display 260 through analysis of the data.
