IMAGE DEVICE AND OPERATING METHOD THEREOF

An image device may include a clock generator to generate a first output clock of a first frequency, a link layer to generate a control signal for changing the first frequency and output first parallel data including first frame information, a detector to generate a collision avoidance command to change the first frequency to a second frequency during a vertical blanking time, and a frequency changer to receive the collision avoidance command from the detector and transmit a frequency change command to the link layer. The link layer transmits the control signal to the clock generator based onthe frequency change command. The vertical blanking time is a time period from a first time point at which the first parallel data is not output from the link layer to a second time point at which second parallel data is output. 一种成像设备可以包括：时钟发生器，用于生成第一频率的第一输出时钟；链路层，用于生成用于改变第一频率并且输出包括第一帧信息的第一并行数据的控制信号；检测器，用于生成冲突避免命令，以在垂直消隐时间期间将第一频率改变为第二频率；以及频率改变器，用于从检测器接收冲突避免命令并且将频率改变命令发送到链路层。链路层基于频率改变命令向时钟发生器发送控制信号。垂直消隐时间是从不从链路层输出第一并行数据的第
