Projection apparatus, elevation angle control method therefor and recording medium

A projection apparatus comprising:

• a distance measuring unit that measures a distance to a screen on which an image is to be projected;
• and
• a projection unit that has a zoom mechanism unit capable of changing zoom magnifications of a projection image, focuses the projection image based on the distance measured by the distance measuring unit and projects the image on the screen;
• and
• the zoom mechanism unit of the projection unit controls a distance measuring range of the distance measuring unit in such a way that a center point of the distance measuring range of the distance measuring unit corresponds to a center point of a projection area of the projection image, wherein the projection area is determined according to the set zoom magnification.
