Abstract

一种图像传输装置，包括：频率检测器，被配置为接收图像帧，检测图像帧的帧率，在检测到帧率发生变化的情况下输出频率切换标记信号；频率配置器，被配置为响应于来自频率检测器的频率切换标记信号，根据安全频率步进值，输出第一配置信号；频率处理器，被配置为输出参考时钟信号，根据第一配置信号，对所输出的参考时钟信号的频率进行多次调整，每次调整的值小于或等于安全频率步进值，直至所输出参考时钟信号的频率大致等于图像帧变化后的帧率对应的参考时钟信号的频率，结束调整；图像帧发送器，被配置为接收图像帧及来自频率处理器的参考时钟信号，根据参考时钟信号将图像帧格式转换为图像帧发送器对应格式，并输出转换格式后的图像帧。
