Image display apparatus and image display method

An image display method utilizing a first optical element and a second optical element, the image display method comprising:

• selecting a pixel of a particular image of a plurality of images having a plurality of viewpoints different from each other, wherein the pixel is included in a particular element pixel of a plurality of element pixels, each of the plurality of element pixels being formed by arranging, in a direction, a plurality of pixels respectively extracted from the plurality of images, on the basis of a selection logic to select a pixel at a position more distant from a position corresponding to an optical axis of the second optical element along the direction in the particular image as an element-to-element distance between the first optical element and the second optical element becomes smaller than a focal length of the second optical element, in order to display a composite image including the plurality of element pixels;
• outputting a pixel value of the selected pixel to a display;
• displaying the composite image by using the display;
• emitting in parallel a plurality of light rays emitted from a plurality of pixels respectively included in the plurality of element pixels, for the particular image by using a plurality of lenses included in the first optical element and arrayed in the direction to correspond to the plurality of element pixels;
• and
• condensing the plurality of light rays emitted from the first optical element by using the second optical element.
