To provide an image projector and a mobile body which can prevent a housing containing the members of an image projector from being heated by entering external light and being broken.SOLUTION: An image projector 500 includes: image generation means 520 for generating a projection image L; an enlargement optical system 511 for enlarging the projection image L generated by the image generation means 520 and projecting the projection image L on a projection surface 401; and a housing 80 containing the image generation means 520 and the enlargement optical system 511. An incident light SL, which enters the enlargement optical system 511 from the outside of the housing 80, propagates in the enlargement optical system 511 in an opposite direction to the direction of the projection image L and is thus collected. The housing 80 has an inner wall surface 80a (80b) in a position other than the region β where the light collecting magnification of the light SL is larger than 15 times.SELECTED DRAWING: Figure 1

    【課題】画像投写装置の各部材を収容する筐体が、入射してきた外光によって昇温し、破損することを抑制できる画像投写装置及び移動体を提供する。【解決手段】投写画像Lを生成する画像生成手段520と、画像生成手段520で生成された投写画像Lを拡大して投写面401に投写する拡大光学系511と、画像生成手段520及び拡大光学系511とを収容する筐体80と、を備える画像投写装置500において、筐体80の外から拡大光学系511に入射した入射光SLが拡大光学系511を投写画L像とは逆向きに伝播することによって集光され、入射光SLの集光倍率が15倍を超える領域βを避けて筐体80の内壁面80a(80b)を配置する。【選択図】図1
