To provide an image plotting device, a vehicular fixture, and an image plotting method, which can suppress a temperature rise of a light source section while miniaturizing the device and reducing power consumption.SOLUTION: An image plotting device (100) includes: a digital mirror device (11) which has a plurality of minute mirrors arrayed on a principal surface and switches angles of the mirrors to the principal surface on the basis of ON information and OFF information included in image data; a light source section (20) which irradiates the plurality of mirrors with light; a temperature acquisition section (12) which measures the temperature of the light source section (20) and acquires a light source section temperature; and an ON-OFF adjustment section (13) which increases the number of pieces of the ON information per unit time included in the image data when the light source section temperature is a first temperature or more.SELECTED DRAWING: Figure 2
【課題】装置の小型化と消費電力の低減を図りながらも、光源部の温度上昇を抑制することが可能な画像描画装置、車両用灯具および画像描画方法を提供する。【解決手段】主面上に微小なミラーが複数配列され、画像データに含まれるオン情報とオフ情報に基づいてミラーの前記主面に対する角度を切り替えるデジタルミラーデバイス(11)と、複数のミラーに対して光を照射する光源部(20)と、光源部(20)の温度を測定して光源部温度を取得する温度測定部(12)と、光源部温度が第1温度以上である場合に、画像データに含まれる単位時間あたりのオン情報の数を増加させるオンオフ調整部(13)を備える画像描画装置(100)。【選択図】図2
