A projector that acquires evaluation values representing how well projection light is brought into focus on a screen, outputs the acquired evaluation values and a maximum value of the acquired evaluation values, and updates the maximum value to a new value at a predetermined timing.
Claims11
An image processing apparatus comprising:
- an evaluation value acquisition section that acquires evaluation values representing how well projection light is brought into focus on a projection surface;
- an output section that outputs the acquired evaluation values and a maximum value of the acquired evaluation values;
- and
- an update section that updates the maximum value to a new value at a predetermined timing,
- wherein the update section updates the maximum value after a state in which the acquired evaluation values are smaller than the maximum value has lasted for a predetermined period.
