PROBLEM TO BE SOLVED: To achieve improvement for solving a defect in a conventional technology.SOLUTION: A projection device includes: a laser device; a setting-adjustable micro-mirror device; and a calculation device. The laser device is configured to generate a laser beam, and the setting-adjustable micro-mirror device is configured to adjust the setting of a projection region as the partial region of the whole projection region of the micro-mirror device, and to form an image on the projection surface by changing the laser beam in the projection region, and the calculation device is configured to control the driving of the setting-adjustable micro-mirror device and the laser device such that a predetermined contrast value of the image formed on the projection surface is achieved for the setting-adjusted projection region. |
