The invention discloses a projection device and a projection method thereof. The projection device comprises a picture update rate conversion chip, a spatial light modulation circuit and a control circuit. The picture update rate conversion chip performs picture update rate conversion on a first video signal to generate a second video signal. The control circuit is coupled to the picture update rate conversion chip and the spatial light modulation circuit, and adjusts the resolution and the picture update rate of the projection image generated by the spatial light modulation circuit accordingto the picture update rate of the second video signal. 一种投影装置及其投影方法。投影装置包括画面更新率转换晶片、空间光调变电路以及控制电路。画面更新率转换晶片对第一视频信号进行画面更新率转换而产生第二视频信号。控制电路耦接画面更新率转换晶片以及空间光调变电路，依据第二视频信号的画面更新率调整空间光调变电路所产生的投影影像的解析度以及画面更新率。
