Projector, and control method thereof

A projector comprising:

• a light source;
• a light modulation device that modulates light emitted from the light source into image light according to an image signal;
• a projection lens that projects the image light modulated by the light modulation device;
• a lens adjustment mechanism that performs a predetermined adjustment operation for the projection lens;
• an adjustment value storage unit that stores lens adjustment values for causing the lens adjustment mechanism to perform the predetermined adjustment operation by linking the lens adjustment values to the type of aspect ratio of the image signal;
• an input terminal unit that includes an input terminal into which the image signal is input;
• a signal aspect ratio recognition unit that recognizes an aspect ratio of the image signal input to the input terminal;
• an adjustment value acquisition unit that acquires, from the adjustment value storage unit, the lens adjustment values corresponding to the type of aspect ratio recognized by the signal aspect ratio recognition unit;
• and
• an adjustment control unit that causes the lens adjustment mechanism to perform a lens adjustment operation based on the lens adjustment values acquired by the adjustment value acquisition unit.
