Projector and method of controlling projector

A projector comprising:

• a sensor that detects an attitude of the projector;
• a processor configured to receive an image signal as an input;
• a display that displays an image based on the inputted image signal;
• and
• an image displacement unit that includes an optical member held to be pivotable and changes a position of an image displayed by the display to a first display position and a second display position according to the detected attitude of the optical member, wherein
• the processor is configured to:
• output a driving signal to the image displacement unit to drive the image displacement unit;
• and
• control the outputted driving signal by setting a waveform of the outputted driving signal output according to the attitude of the projector detected by the sensor.

A method of controlling a projector, the method comprising:

• inputting an image signal;
• displaying, by a display, an image based on the image signal;
• driving an image displacement unit according to a driving signal to change a position of the image to be displayed by the display;
• and
• changing an output timing at which the driving signal is output to the image displacement unit according to a change in a frequency of the image signal by correcting a delay time of the output timing based on a difference between the frequency of the image signal and a preset frequency.
