    Abstract: 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 on the 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.

    Abstract: An image sensor includes a photo gate controller configured to generate a plurality of demodulated signals respectively corresponding to a plurality of rows of a pixel array and a photo gate driver configured to adjust a phase of the demodulated signals using a source clock signal to remove power, voltage and temperature (PVT) noise and to apply the phase-adjusted demodulated signals to the pixel array. The image sensor matches the phases of the respective demodulated signals using the source clock signal generated based on a reference clock signal, thereby increasing the quality of depth images.
