Problems solved by technology
This method is more effective for static or gradually changing environments. However, when the light detection device is affected by interference or fluctuations, such as sudden changes in light, the detected light intensity may deviate, resulting in inaccurate reflection of light changes. Resulting in inability to accurately adjust TV brightness

Embodiment Construction
[0027] An embodiment of the present invention provides a device for detecting light intensity of a TV viewing environment. The device can be installed in a smart TV to accurately detect the light intensity of the viewing environment as a reference for adjusting screen brightness. figure 1 It is a schematic diagram of a detection device 100 for light intensity of a television viewing environment according to an embodiment of the present invention. The detection device 100 may generally include: an image acquisition module 110 , a face recognition module 120 , an area estimation module 130 , a light intensity calculation module 140 , a human body modeling module 150 , and an image cropping module 160 . The above modules can be flexibly configured according to the functions required by the device 100 for detecting the light intensity of the TV viewing environment in this embodiment, and it is not required to install all the modules at the same time.
[0028] Among the above compo...

The invention provides a method and a device for detecting the intensity of light in a television watching environment and a smart television. The method for detecting the intensity of light in a television watching environment comprises the following steps: acquiring an environment image in a predetermined area in front of a television; identifying a face in the environment image to obtain a face image contained in the environment image; calculating the area covered by a human body in the environment image according to the face image; and working out the light intensity of the image beyond the area covered by the human body in the environment image and taking the light intensity as a parameter of television brightness adjustment. According to the scheme of the invention, the face in the image is identified, and the area covered by the human body in the image is eliminated during light intensity calculation, so that the influence of the human body to the light intensity is avoided, and the calculated light intensity is more in line with the actual situation of the television watching environment.
Description
technical field [0001] The invention relates to the field of smart home appliances, in particular to a method and device for detecting light intensity in a TV viewing environment and a smart TV. Background technique [0002] The picture mode of the traditional TV depends on the manual adjustment of the user himself. The user needs to enter the image adjustment interface through the remote control to adjust the brightness, contrast, and color accordingly. [0003] However, as the viewing time of the program is different, the intensity of ambient light is different, resulting in a different experience for the user watching the program. Therefore, when watching TV, the user needs to adjust the brightness of the TV screen according to the brightness of the ambient light. For example, when the brightness of the ambient light is high, the user needs to increase the brightness of the TV screen, and when the brightness of the ambient light is low, the user needs to adjust the brig...
