技術說明

一種2D/3D(二維/三維)雙模式之影像感測電路，包含有：一光電二極體，用以感測光信號並將之轉為電子信號；一主動感測單元，電性連接於該光電二極體的一端，用以接收該光電二極體所輸出的電子信號，；該主動感測單元具有一輸出端；以及一降壓單元，電性連接於該主動感測單元之輸出端，該降壓單元還具有一降壓控制端；該降壓單元係藉由該降壓控制端受外部控制以開啟/關閉該降壓單元，藉以對該主動感測單元接於該光電二極體的那一端所輸出的信號進行降壓/不降壓的動作；藉由控制該降壓單元的開啟/關閉，即可在開啟所對應的3D模式以及關閉所對應的2D模式之間進行切換。 A 2D/3D dual-mode image sensing circuitry is composed of a photodiode, an active sensing unit, and a pull-down unit. The photodiode is to detect and convert optical signals into electronic signals. The active sensing unit is electrically connected with one end of the photodiode for receiving electronic signals outputted by the photodiode, having an output. The pull-down unit is electrically connected with the output, providing a pull-down path. The pull-down unit has a pull-down control terminal, by which the pull-down unit can be externally controllably switched on/off, for sinking the potential or not to the aforesaid end of the photodiode. In this way, as the 2D mode is switched on, the 3D mode is switched off; on the other hand, as the 3D mode is switched on, the 2D mode is switched off.
