Image device and operating method thereof

An image device, comprising:

• a detector to generate a collision avoidance command;
• a frequency changer to receive the collision avoidance command from the detector and generate a frequency change command;
• a link layer to receive the frequency change command from the frequency changer, generate a control signal based on the frequency change command, and output first parallel data including first frame information;
• and
• a clock generator to receive the control signal from the link layer and generate a first output clock of a first frequency, wherein:
• the first frequency is changed to a second frequency during a vertical blanking time, the second frequency being different from the first frequency, and
• 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, the second parallel data including second frame information subsequent to the first frame information.

An image device, comprising:

• a link layer to generate first parallel data including first frame information, the first parallel data being not generated from a first time point;
• a first peripheral circuit to operate at a first bandwidth;
• a clock generator to generate a first output clock of a first frequency;
• a detector to sense whether there is frequency collision between the first bandwidth and the first frequency and generate a collision avoidance command when the frequency collision is sensed;
• and
• a frequency changer to receive the collision avoidance command from the detector and generate a frequency change command to change the first frequency to a second frequency after the first time point, the second frequency not colliding with the first bandwidth.
