The invention relates to the technical field of head-up display, particularly provides an image generation device and a head-up display, and can solve the problem of high power consumption of the head-up display to a certain extent. The image generation device comprises a light source, a collimation unit and a display screen which are sequentially arranged in the light path direction, the light source comprises a light source set, and the light source set comprises light source units; the collimating unit comprises collimating lens groups in one-to-one correspondence with the light source groups, and any collimating lens group comprises collimating lenses in one-to-one correspondence with the light source units. The light source comprises a first light source group which comprises a first light source unit and an Nth light source unit, and light emitted by the first light source unit penetrates through the display screen and forms a virtual image at the position of the first eye box after passing through the light adjusting assembly; light emitted by the Nth light source unit penetrates through the display screen and forms a virtual image at the position of the Nth eye box after passing through the light adjusting assembly. The image generation device is beneficial to reducing the power consumption of the head-up display.

    本公开涉及抬头显示技术领域,具体而言,提供一种图像生成装置与抬头显示器,可以在一定程度上解决抬头显示器功耗较高的问题。图像生成装置包括沿光路方向依次设置的光源、准直单元与显示屏,光源包括光源组,光源组包括光源单元;准直单元包括与光源组一一对应的准直透镜组,任一准直透镜组包括与光源单元一一对应的准直透镜。光源包括第一光源组,包括第一光源单元与第N光源单元,第一光源单元发射的光线透过显示屏,经光调节组件后在第一眼盒位置形成虚像;第N光源单元发射的光线透过显示屏,经光调节组件后在第N眼盒位置形成虚像。本公开的图像生成装置有利于降低抬头显示器的功耗。
