PROBLEM TO BE SOLVED: To provide a projector and a head-up display device that can suppress a striped pattern caused by a change in brightness in a vertical scanning direction from being visually recognized by a user.SOLUTION: A head-up display device (projector) 100 includes: a laser light source 11 that emits light of an image to be projected; an optical scanning part 13 that scans the light from the laser light source 11 in a horizontal scanning direction and a vertical scanning direction; a light detection part 19 for detecting brightness in the vertical scanning direction of the light scanned by the optical scanning part 13; and a control part 22 that performs, on the basis of a change in brightness in the vertical scanning direction based on the brightness detected by the light detection part 19, control to correct the brightness in a direction where a difference in brightness is reduced in the change in brightness.

    【課題】垂直走査方向における輝度変化に起因する縞模様がユーザに視認されるのを抑制することが可能なプロジェクタおよびヘッドアップディスプレイ装置を提供する。【解決手段】このヘッドアップディスプレイ装置(プロジェクタ)100は、投影する画像の光を照射するレーザ光源11と、レーザ光源11からの光を水平走査方向および垂直走査方向に走査する光走査部13と、光走査部13により走査された光の垂直走査方向における輝度を検出するための光検出部19と、光検出部19により検出された輝度に基づく垂直走査方向における輝度変化に基づいて、輝度変化における輝度差が小さくなる方向に輝度を補正する制御を行う制御部22と、を備える。【選択図】図8
