Projector and control method of projector

A projector comprising:

• a receiving unit that receives a first measurement result obtained by measurement of a feature quantity of a first image projected on a projection surface from a position at a first angle relative to the projection surface and a second measurement result obtained by measurement of the feature quantity of the first image in a position at a second angle different from the first angle relative to the projection surface;
• a determination unit that determines reflection characteristics of the projection surface based on the first measurement result and the second measurement result;
• a correction unit that corrects first image information and generates second image information based on the reflection characteristics of the projection surface determined by the determination unit;
• and
• a projection unit that projects a second image according to the second image information generated by the correction unit on the projection surface.

A method comprising:

• measuring a feature quantity of a first image projected on a projection surface from a position at a first angle relative to the projection surface and generating a first measurement result;
• receiving a second measurement result obtained by measurement of the feature quantity of the first image in a position at a second angle different from the first angle relative to the projection surface;
• determining reflection characteristics of the projection surface based on the first measurement result and the second measurement result;
• correcting first image information and generating second image information based on the reflection characteristics of the projection surface;
• and
• projecting a second image according to the second image information on the projection surface.
