Abstract: A projection direction change device includes a mirror that reflects light emitted from a projection lens unit of a projector, a mirror support part that rotatably supports the mirror around a first axis and a second axis, a first drive part that rotary drives the mirror around the first axis, and a second drive part that rotary drives the mirror around the second axis. An intersecting point of the first and second axes is positioned closer to the projection lens unit than a geometric barycenter of the mirror is.

Abstract: An image display device includes an image input unit into which an image signal from an image signal source is input; a memory; a writing unit that writes at a first frequency an image signal input into the image input unit into the memory; a reading unit that reads at a second frequency higher than the first frequency an image signal written in the memory; an image output unit that outputs an image signal read by the reading unit to a display unit; and an image interpolation unit that interpolates an image to be output to the display unit.
