The playback quality and the playback effect of the panoramic picture of the flat display device can be better improved.

Please refer to FIG. 1. FIG. 1 is a flowchart of a first preferred embodiment of a method for adjusting a panoramic picture according to the present invention. The panoramic picture adjustment method of the preferred embodiment may be implemented by using the above-mentioned flat display device, and the panoramic picture adjustment method includes:

Step S101: Receive a screen adjustment instruction, where the screen adjustment instruction is used to set the cylinder panoramic screen to a preset display area having a set screen deformation amount;

Step S102, acquiring a current display area of the cylindrical panoramic picture according to the screen adjustment instruction;

Step S103, determining a picture adjustment parameter of the cylindrical panoramic picture according to the current display area of the cylindrical panoramic picture and the preset display area;

Step S104, adjusting the cylindrical panoramic picture to the preset display area based on the picture adjustment parameter.

In step S101, the plane display device receives a screen adjustment command, which may be an instruction for the user to adjust the current display area of the flat display device. When the user views the cylindrical panoramic picture using the flat display device, the general user views the picture along the cylindrical extension direction of the cylindrical projection surface of the cylindrical panoramic picture. In this viewing direction, the amount of image distortion of the display screen is relatively uniform. If the viewing area of the user is close to the center line of the cylindrical projection surface of the cylindrical panoramic image, the amount of image distortion of the viewing area will be very small.

When the user does not view the picture in the direction of the cylinder extending from the cylindrical projection surface of the cylindrical panoramic picture, the user's viewing area is likely to be far from the center line of the cylindrical projection surface of the cylindrical panoramic picture, which results in the current display of the cylindrical panoramic picture. The amount of image distortion in the area will be very large, especially away from the display side of the center line of the cylindrical projection surface, thus affecting the playback quality and playback effect of the panoramic picture.

Therefore, the user can set the cylinder panoramic screen to the preset display area having the set screen deformation amount (ie, near the center line of the cylindrical projection surface of the cylindrical panoramic screen) by issuing a screen adjustment instruction, thereby improving the playback effect of the panoramic screen. .

Then it proceeds to step S102.

In step S102, the plane display device acquires the current display area of the cylinder panoramic screen according to the screen adjustment instruction acquired in step S101. The current display area is the cylinder panoramic picture area currently being displayed by the flat display device. Then it proceeds to step S103.

In step S103, the plane display device acquires the current display area of the cylindrical panoramic picture acquired in step S102 and the preset display area. The preset display area means that the user presets a cylindrical panoramic screen area having a set screen deformation amount, and the preset display area has a small amount of screen distortion. The area of the preset display area may be substantially equal to the display area of the flat display device.

Therefore, the plane display device determines the screen adjustment parameter of the cylindrical panoramic screen according to the current display area and the preset display area, that is, the movement parameter of the display screen of the flat display device from the current display area to the preset display area. If the preset display area is located at the lower left of the current display area, the screen adjustment parameter is a display screen movement parameter of the display screen of the flat display device moving from the current display area to the lower left to the preset display area. Then it proceeds to step S104.

In step S104, the plane display device adjusts the cylinder panoramic screen to the preset display area based on the screen adjustment parameter acquired in step S103, thereby reducing the amount of screen distortion of the display screen of the cylindrical panoramic screen and improving the playback of the panoramic screen. Quality and playback effects.

This completes the screen adjustment process of the panoramic picture adjustment method of the preferred embodiment.

The panoramic picture adjustment method of the preferred embodiment can quickly adjust the display area of the flat display device to the preset display area by setting the preset display area with the set screen deformation amount, and realize the on-plane display by the screen adjustment instruction.
