To provide a display unit and a display method that improves uniformity (degree of uniformity) of a light quantity distribution at or near an end in a sub-scanning direction (for example, horizontal scanning direction in two-dimensional scanning) on a surface to be scanned when the surface is scanned with uniform light so as to improve image quality, and provide a head-up display and a vehicle.SOLUTION: When a small area, of a plurality of small areas, which is located closer to a center part in a main scanning direction of a drawing area is determined as a first small area, and a small area located closer to an end in the main scanning direction of the drawing area as a second small area, and the brightness of the first small area and the brightness of the second small area in drawing data are the same, a light source control unit controls a light source, with two-dimensional scanning, so that the distribution of the intensity of light applied from the light source to the first small area and the distribution of the intensity of light applied from the light source to the second small area become different from each other.SELECTED DRAWING: Figure 15
【課題】均一の光で走査した際の被走査面における副走査方向(例えば二次元走査における水平走査方向)の端部又はその近傍の光量分布の均一性(均一度合い)を向上させ画質向上を図ることができる表示装置、表示方法、ヘッドアップディスプレイ及び車両を提供する。【解決手段】複数の小領域のうち、描画領域の主走査方向における中央部側に位置する小領域を第1の小領域、描画領域の主走査方向における端部側に位置する小領域を第2の小領域と定義し、描画データにおける第1の小領域の輝度と第2の小領域の輝度とが同じである場合に、光源制御部は、二次元走査により、光源から第1の小領域へ照射される光の強度分布と光源から第2の小領域へ照射される光の強度分布とが、互いに異なるように、光源を制御する。【選択図】図15
