Abstract: A device has memory and processing circuitry coupled to the memory. The processing circuitry generates a resonant axis drive signal to drive a Micro Electro Mechanical System (MEMS) mirror system at a resonance frequency, and generates a linear axis drive signal to drive the MEMS mirror system at a linear frequency corresponding to a video frame rate. Generating the linear axis drive signal includes generating, using interpolation, a current set of shape values based on a stored set of shape values and an indication of the video frame rate. The linear axis drive signal is generated using the current set of shape values.
