An image displaying device includes laser beam sources that emit laser beams of mutually differing color components. The image display device projects an image based on a test pattern that includes a reference mark indicating horizontal and vertical reference positions by a mixed color of color components of the mutually differing color components, and bar marks arranged at specific intervals in the horizontal and vertical directions relative to the reference mark, for each color component, is used. Arrangement of the bar marks in the image data is an arrangement in which a distance from the reference mark is used as a reference, and for pairs of bar marks for bar marks of mutually differing color components, an amount of offset between bar marks in each of the bar mark pairs increases with fixed increments proportional to the distance from the reference mark. |

1. An image displaying device comprising:
a plurality of laser beam sources that emit laser beams of mutually differing color components, wherein the image display device projects, based on image data, an image by scanning the laser beams of the mutually differing color components emitted from the plurality of laser beam sources, wherein the image data comprises image data of a test pattern that includes:
a reference mark that indicates horizontal and vertical reference positions by a mixed color of a plurality of color components of the mutually differing color components; anda plurality of bar marks arranged at specific intervals in the horizontal and vertical directions relative to the reference mark, for each color component, is used, and wherein arrangement of the bar marks in the image data is an arrangement in which:
a distance from the reference mark is used as a reference, andfor pairs of bar marks for bar marks of mutually differing color components, an amount of offset between bar marks in each of the bar mark pairs increases with fixed increments proportional to the distance from the reference mark. |
