PROJECTION IMAGE DISPLAY DEVICE, AND IMAGE ADJUSTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a projection image display device and an image adjusting method for reducing processing time and cost required for adjustment of a shape of an image to be projected on a projection surface.

SOLUTION: The projection image display device 100 is configured to display a test pattern image constituting at least a part of each of three or more line segments composing three or more cross points. The projection image display device 100 calculates a positional relationship between the projection image display device 100 and the projection surface 400 based on the three or more cross points contained in the imaging test pattern image. The test pattern image to be projected to the projection surface 400 has a distortion in a direction opposite to that of the lens used for imaging the test pattern image.
