Abstract: A projection type image display apparatus includes an adjusting sub-frame image generator and a shift amount adjuster. The adjusting sub-frame image generator generates a primary adjusting sub-frame image having a design in which a first line having a first color and a width of an N pixel (N being a natural number) is displayed on a background image having a second color, and a secondary adjusting sub-frame image having a design in which a second line having a third color and a width of an M pixel set to N=M+α (M being an integer equal to or greater than 1, α being an integer equal to or greater than 0) is displayed on a background image having a fourth color. The shift amount adjuster adjusts the shift amount when the display positions of the primary and secondary adjusting sub-frame images on the projection surface are shifted relatively to each other.

Abstract: A projection video display apparatus includes: a converter that converts an input video signal having a first number of pixels and a first frame rate into a conversion video signal having a second number of pixels and a second frame rate, the second number of pixels being smaller than the first number of pixels, and the second frame rate being an n-th multiple (n is an integer of 2 or greater) of the first frame rate; an optical element that displaces an optical axis of the video light beam; an optical element driving unit that drives the optical element at a frequency F being a natural-number multiple of the first frame rate; and a rotating body that rotates at a rotation speed R. The rotation speed R is set so as to become a value within a predetermined range corresponding to the frequency F.
