System and method for preventing screen of image display device from vibrating

Abstract

The invention relates to a system and a method for controlling an image display device not to influence image viewing comfort caused by shaking of the device when the device displays an image in a nonstatic state. The system detects a moving track of a display screen on the display device through a three-dimensional phase detector; an image control unit records the initial position of the image on the display screen; a digital signal processor converts three-dimensional displacement variation detected by the detector into a two-dimensional planar offset, receives the image initial position recorded by the image control unit, and calculates another image initial position output to the display screen by matching the converted two-dimensional offset; and an image phase adjustment unit adjusts an image output scope according to the new image initial position and makes pictures on the display screen kept on the same position after a new image is output onto the display screen. The image pictures on the display screen cannot shake because of the movement of the display device so as to reduce uncomfortableness during viewing the pictures.

Description

technical field [0001] The invention relates to a system for preventing the image screen from shaking with the image display device, especially an anti-vibration system that detects the displacement change of the device and calculates the output position of the image according to the displacement change to keep the image display position fixed . Background technique [0002] There are many types of digital devices that can display images, and some devices are portable devices that can be carried by users. Users can use such devices to watch video files, When taking pictures or reading documents, the image display device will experience slight shaking. [0003] However, the image frame on the image display device does not adjust its display angle or position accordingly because of the change of the angle or position of the device, so the user moves the display device no matter what, the same image file on the display device, its The display screen and display range on the s...

[0003] However, the image frame on the image display device does not adjust its display angle or position accordingly because of the change of the angle or position of the device, so the user moves the display device no matter what, the same image file on the display device, its The display screen and display range on the screen are exactly the same; however, if the display range of the video screen is not adjusted, from the user's point of view, it is because the display range of the image has not been adjusted, but the image will follow the device. Tilt (see Figure 1A ), Shift ( Figure 1B )the result of

If you watch text or images on this type of device in a continuously shaking environment, the image screen will also show continuous shaking, and the user's eyes must constantly refocus their sights to watch or read clearly. It is easy to cause eye discomfort or dizziness due to the continuous shaking of the screen

[0004] Although there are many technologies for preventing slight vibration when capturing external images in the existing inventions, most of them are dedicated to controlling the vibration amplitude when capturing images, and it is rare to solve the problem of preventing the image from being displayed when viewing images on the screen for a continuous period of time. shaking technique
