PROBLEM TO BE SOLVED: To provide a display image projection device and display image projection method capable of suppressing a decrease of an information amount to be displayed while increasing the luminance of display without increasing the luminance of light sources.SOLUTION: The display image projection device includes a plurality of light sources (22a to 22c), a plurality of micromirror devices (23a to 23c) for reflecting light from the respective light sources (22a to 22c) to perform scanning, and a control part (21) for controlling the plurality of light sources (22a to 22c) and the plurality of micromirror devices (23a to 23c). The control part (21) controls the plurality of micromirror devices (23a to 23c) so as to cause a scanning range to at least one prescribed light source among the plurality of light sources (22a to 22c) to be narrower than a scanning range to the light sources other than the prescribed light source.SELECTED DRAWING: Figure 2

    【課題】光源の輝度を上げることなく表示の輝度を上げつつ、表示する情報量の低下を抑制することができる表示画像投影装置及び表示画像投影方法を提供する。【解決手段】複数の光源(22a〜22c)と、各光源(22a〜22c)からの光を反射して走査する複数のマイクロミラーデバイス(23a〜23c)と、複数の光源(22a〜22c)及び複数のマイクロミラーデバイス(23a〜23c)を制御する制御部(21)と、を備え、制御部(21)は、複数の光源(22a〜22c)のうち少なくとも1つの所定光源に対する走査範囲を、所定光源以外の光源に対する走査範囲よりも狭くするように複数のマイクロミラーデバイス(23a〜23c)を制御する。【選択図】図2
