Abstract

The invention discloses a high-accuracy method for adjusting parameters. The method includes connecting an external device for adjusting special effect parameters; setting monitoring threads to obtain output data of the external device; and analyzing the output data and modifying corresponding special effect parameters in a special effect parameter adjusting system, and performing high-accuracy adjustment on the special effect parameters. According to the method for adjusting special effect parameters through the external device, the parameter adjustment is flexible, the speed of the parameter adjustment can be increased, and the parameter adjustment is accurate.

Description

technical field [0001] The invention relates to the technical field of special effect adjustment in the field of radio and television, in particular to a method and system for adjusting special effect parameters with high precision. Background technique [0002] With the development of video technology, people have higher and higher requirements for video quality, special effect display and other visual effects. Therefore, special effect adjustment is a crucial link in the video production process. [0003] In the prior art, the adjustment of video special effects is generally performed by directly adjusting the parameters in the software with a mouse, etc., but this method is inflexible in adjusting the parameters, and the accuracy is not high. [0004] Wave Panel is an external device with HID (human interface device, supporting human-machine interface device) protocol, which has various adjustment components such as adjustment buttons, knobs, and rotating balls. It can ad...
