Abstract

一种信号处理方法，包括：获得第一帧同步信号；第一帧同步信号包括多个第一脉冲，一个第一脉冲的后沿和第一脉冲的后一第一脉冲的前沿之间的时间为第一时间，第一时间对应第一整数个第一像素时钟信号的脉冲；生成同步校准信号；同步校准信号包括多个第二脉冲，每个第二脉冲的触发沿与一个第一脉冲的后沿处于同一时刻；第二脉冲的触发沿为第二脉冲的前沿或后沿，第二脉冲的宽度与第一像素时钟信号的脉冲宽度或第二像素时钟信号的脉冲宽度相等；生成第二帧同步信号；第二帧同步信号包括多个第三脉冲，每个第二脉冲的触发沿与第二脉冲之后最靠近的一个第三脉冲的前沿之间的时间为第二时间，第二时间对应第一整数个第二像素时钟信号的脉冲。
