Embodiment 1

[0058] image 3 It is a schematic flowchart of a method for adjusting an aspect ratio of a smart TV provided in the present application.

[0059] Please refer to image 3 As shown, a method for adjusting the screen ratio of a smart TV provided in the embodiment of the present application includes:

[0060] S100: Obtain the screen aspect ratio of the current video and the display aspect ratio of the TV;

[0061] Here, the screen aspect ratio of the current video refers to the ratio of the horizontal width to the vertical height of the original video screen, and the aspect ratio of the TV display screen refers to the ratio of the horizontal width to the vertical height of the TV display screen. In real experience , the aspect ratio of the current video does not necessarily match the aspect ratio of the TV display. Therefore, when the current video is played on the TV display, there will be black borders between the current video image and the display interface, affecting user...

Embodiment 2

[0068] Figure 4 It is a schematic flowchart of a method for obtaining the aspect ratio of a video provided in this application.

[0069] Please refer to Figure 4 As shown, the method includes:

[0070] S101: Obtain the pixel ratio and resolution of the current video; wherein, the pixel ratio is the ratio of the horizontal width to the vertical height of a single pixel, and the resolution is the number of pixels of the video in the horizontal direction and the pixels in the vertical direction ratio of numbers;

[0071] S102: Multiply the pixel ratio of the current video by the resolution, and use the product value as the aspect ratio of the video.

[0072] Generally, the pixel ratio is the ratio of the horizontal width to the vertical height of a single pixel, the resolution is the ratio of the number of pixels in the horizontal direction to the number of pixels in the vertical direction of the video, and the product value of the pixel ratio of the video and the resolution...

Embodiment 3

[0078] Figure 5 It is a schematic flowchart of a method for adjusting the aspect ratio of the current video on the display screen of the TV according to the aspect ratio of the current video and the aspect ratio of the display screen of the TV provided by the present application.

[0079] Please refer to Figure 5 As shown, the method includes:

[0080] S201: Compare the screen aspect ratio of the current video with the aspect ratio of the display screen of the TV;

[0081]For videos whose picture aspect ratio does not fit the TV display screen, when the video screen aspect ratio is not smaller than the display screen aspect ratio, when the video horizontal direction fills the display screen, the vertical direction of the video is also closed. It is sufficient to fill the display screen and exceed the vertical height range of the display screen. In view of this situation, the screen ratio adjustment method provided by the embodiment of the present application may specifical...

Abstract

The invention discloses a method and device for adjusting the proportion of a picture of a smart television. The method comprises the step of obtaining the picture aspect ratio of a current video and the aspect ratio of a display screen of the television and the step of adjusting the proportion of the picture of the current video on the display screen of the television to enable the display screen of the television to be fully paved with the current video in the horizontal direction according to the picture aspect ratio of the current video and the aspect ratio of the display screen of the television . The left and right letter boxes of the video on a play interface in the display screen of the television in the horizontal direction can be automatically removed no matter what kind of the picture proportions of the current accessed videos is, the picture proportion can be more suitable for watching, the trouble that a user needs to manually adjust is avoided while a good watching effect is obtained, user operation procedures are simplified, and user experience is improved.

Description

technical field [0001] The present application relates to the field of smart TVs, in particular to a method and device for adjusting the screen ratio of a smart TV. Background technique [0002] With the improvement of people's living standards, the penetration rate of smart TVs in families is becoming more and more widespread, and the trend of replacing traditional TVs is getting stronger and stronger. Smart TVs play an increasingly important role in people's daily leisure and entertainment life. [0003] At present, the screen ratios of different TV program videos on the TV display screen are not uniform. Most high-definition digital TV program videos are played in a 16:9 screen ratio, but most ordinary TV program videos are played in a 4:3 screen ratio. At the same time, there are also situations where some TV program videos are played in a special aspect ratio. In addition, due to the non-uniform production standards, the screen ratios of online videos produced by diffe...
