Claims18
An image output method, comprising:
- acquiring an image continuous change feature of a display interface of a local server;
- generating image output control information according to the image continuous change feature and a corresponding image change threshold;
- and
- controlling amount of output image data according to the image output control information and network congestion information;
- wherein controlling the amount of the output image data according to the image output control information and the network congestion information comprises:
- executing, according to the image output control information and the network congestion information, at least one of following;
- calculating a quantization step size update value, generating an instruction for discarding an image cache frame;
- wherein calculating the quantization step size update value according to the image output control information and the network congestion information comprises:
- acquiring the number of image frames to be sent at a current moment, a first moment and a second moment, wherein the first moment is earlier than the current moment and the second moment is earlier than the first moment;
- acquiring an initial quantization step size at the first moment in an image compression process;
- determining network congestion change information according to a numerical change relationship of the number of the image frames to be sent at the current moment, the first moment and the second moment;
- and
- adjusting the initial quantization step size on a basis of the network congestion change information, to obtain a quantization step size at the current moment.
One or more non-transitory computer-readable storage medium storing computer-readable instructions, wherein the computer-readable instructions, when executed by one or more processors, cause the one or more processors to:
- acquire an image continuous change feature of a display interface of a local server;
- generate image output control information according to the image continuous change feature and a corresponding image change threshold;
- and
- control amount of output image data according to the image output control information and network congestion information;
- wherein controlling the amount of the output image data according to the image output control information and the network congestion information comprises:
- executing, according to the image output control information and the network congestion information, at least one of following:
- calculating a quantization step size update value, generating an instruction for discarding an image cache frame;
- wherein calculating the quantization step size update value according to the image output control information and the network congestion information comprises:
- acquiring the number of image frames to be sent at a current moment, a first moment and a second moment, wherein the first moment is earlier than the current moment, and the second moment is earlier than the first moment;
- acquiring an initial quantization step size at the first moment in an image compression process;
- determining network congestion change information according to a numerical change relationship of the number of the image frames to be sent at the current moment, the first moment and the second moment;
- and
- adjusting the initial quantization step size on a basis of the network congestion change information, to obtain a quantization step size at the current moment.
