The invention provides an image projection apparatus which uses a plurality of light sources which emit light of the same light beam to draw a plurality of images and suppresses variation of illuminance (brightness) for the projected images. This image projection apparatus (1) is provided with a plurality of light sources (2a-2c) and a plurality of lenses (4a-4c) respectively facing the plurality of light sources (2a-2c). The plurality of lenses (4a-4c) each have different diameters (r1-r3), and the lens (4b) with a larger diameter projects an image (G) to a position farther from the image projection device (1) than the lens (4a) with a smaller diameter.
本发明提供一种图像投影装置,该图像投影装置使用射出相同光束的光的多个光源描绘多个图像,且针对所投影的图像抑制照度(亮度)的偏差。本申请的图像投影装置(1)具备多个光源(2a~2c)和与多个光源(2a~2c)分别对置的多个透镜(4a~4c)。多个透镜(4a~4c)分别具有不同的直径(r1~r3),直径较大的透镜(4b)与直径较小的透镜(4a)相比将图像(G)投影至离图像投影装置(1)更远的位置。
