specific Embodiment approach 1

[0060] First of all, it should be explained that assuming that the image display area in the display screen is a rectangle, and assuming that when the display screen rotates with a straight line in the horizontal direction as the rotation axis, the part of the rectangle above the rotation axis is equivalent to the rotation relative to the observation point. The part of the backward displacement, on the contrary, the part of the rectangle below the rotation axis is equivalent to the part of the forward displacement relative to the observation point. Therefore, after rotation, the uppermost area of ​​the rectangle is the farthest area moved relative to the observation point, and the lowermost area is the closest area moved relative to the observation point. Based on the above, when determining how much the display area of ​​each area needs to be increased or reduced, first, according to the data measured by the gyroscope, it is possible to determine the distance that the side far...

specific Embodiment approach 2

[0076] In practical applications, other methods can also be used to calculate the amount by which the side farthest from the observation point needs to be extended and the side closest to the observation point needs to be shortened after the display screen is rotated. For example, a coefficient k can be simply set (this value can be set in advance according to actual needs), when the displacement h of the side farthest from the observation point moves backward or the displacement h of the side closest to the observation point moves forward Afterwards, the displacement value can be directly multiplied by the coefficient to obtain the corresponding amount to be extended or shortened. That is, it can be calculated by the following formula (4):

[0077] x'=kh (4)

[0078] After calculating the amount to be extended for the side farthest from the observation point and the amount to be shortened for the side closest to the observation point, the subsequent processing flow may be th...

Abstract

The invention discloses a three-dimensional anti-shake displaying method. The method includes: reserving a non-image-display area in a display screen in the initial state; detecting whether the display screen rotates or not; and if yes, regulating an image of a display area in the display screen so as to keep the shape of the image observed at an observation point unchanged. By the use of the three-dimensional anti-shake displaying method, when the display screen rotates, the shape of the image observed in the display screen can be kept unchanged, so that displaying effect of the image is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for 3-dimensional anti-shake display. Background technique [0002] With the rapid development of computer technology, mobile terminal equipment has been widely popularized, and people can view information and surf the Internet through mobile terminal equipment anytime and anywhere, which greatly enriches people's daily life. In some applications, the following situations may occur: people may use mobile terminal devices on vehicles such as vehicles, and the mobile terminal devices may not be fixed at a certain position in the car, but only placed in the car Inside. However, phenomena such as brakes, quick starts, or bumps may occur during the driving of the vehicle, which may cause the position of the mobile terminal device to move, and this displacement may be a movement in a three-dimensional space. For example, the display screen of the mobile terminal may be rot...
