IMAGE DISPLAY APPARATUS AND IMAGE ADJUSTMENT METHOD OF IMAGE DISPLAY APPARATUS

摘要

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.

1. An image display apparatus adapted to display an image modulated by a light modulator on an image display surface, comprising:
a non-transitory computer-readable medium encoded with a computer program configured to: display a test pattern in a display region, the test pattern including a plurality of indexes arranged in one of a horizontal direction and a vertical direction with respect to the display region; set at least one of the plurality of indexes as a reference index; adjust the intervals of the indexes of the test pattern so as to increase or decrease, as a distance from the reference index increases with respect to the direction of the arrangement of the indexes; and correct linearity of the image based on the adjusted intervals of the indexes.
