Abstract
An image display apparatus includes an OSD processing section that displays a test pattern, which includes a plurality of index lines arranged in one of horizontal and vertical directions with respect to a pixel area of a liquid crystal light valve at regular intervals, in the pixel area, an input operation section that sets at least one of the plurality of index lines as a reference index line, and adjusts the intervals of the index lines of the test pattern so as to increase or decrease as a distance from the reference index line increases with respect to the direction of the arrangement of the index lines taking the reference index line as a reference, and an image correction section that corrects linearity of the image based on the intervals of the index lines adjusted by the input operation section.
