Image caching system, image caching method, image caching architecture and vehicle

The invention provides an image caching system, an image caching method, an image caching architecture and a vehicle, the image caching system comprises a first buffer, a caching pipeline switch and a second buffer, the input end of the caching pipeline switch is connected with the first buffer, the output end of the caching pipeline switch is connected with the input end of the second buffer, and the output end of the second buffer is connected with the input end of the first buffer. The input end of the first buffer and the input end of the second buffer are both suitable for being connected with an input interface, and the output end of the first buffer, the output end of the second buffer and the output end of the buffer pipeline switch are all suitable for being connected with an output interface. And the cache pipeline switch is suitable for controlling the connection and disconnection of the first cache and the second cache according to the current cache capacity of the input interface and the synchronous cache capacity of the output interface. According to the invention, the video or image watching experience of the user is ensured.
