Abstract

The invention discloses a hardware vertical synchronization signal obtaining method and device, equipment and a storage medium. The method comprises the steps that a first timestamp provided by external equipment and the screen refresh rate of the external equipment are acquired, wherein the first timestamp is generated by the external equipment according to the occurrence moment of a hardware vertical synchronization signal of a display screen of the external equipment; the first timestamp is converted into a second timestamp of terminal equipment; and according to the second timestamp and the screen refresh rate of the external equipment, the occurrence time of a hardware vertical synchronization signal of the terminal equipment is determined.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a method for acquiring a hardware vertical synchronization signal, a device for acquiring a hardware vertical synchronization signal, a terminal device, and a computer-readable storage medium. Background technique [0002] Since head-mounted display devices can present vivid videos to users, they are widely used in people's daily life. Existing head-mounted display devices are divided into independent head-mounted display devices and split-type head-mounted display devices that need to interact with terminal devices such as mobile phones. [0003] For a split head-mounted display device, since the head-mounted display device and the terminal device are two different and independent systems, the terminal device cannot directly obtain the hardware vertical synchronization signal of the head-mounted display device. This will cause the terminal device to only use s...
