An imaging block includes a prism, first and second imaging devices, an analog/digital convertor, a timing generator, and first ,second ,third circuit boards. The prism separates light incident through a lens into at least two colors and outputs the light. The first and second imaging devices are each generates a video signal by photoelectrically converting the light. The analog/digital converter converts the video signal output from each of the devices into a digital signal. The timing generator generates a video-signal processing clock for driving the first imaging device, the second imaging device, and the analog/digital converter. The first imaging device is mounted on the first circuit board. The analog/digital converter and the timing generator are mounted on the second circuit board. The second imaging device is mounted on third circuit board and connected to both the first circuit board and the second circuit board through a cable.一成像區塊包括一稜鏡、第一及第二成像裝置、類比/數位轉換器、時序產生器、及第一、第二、第三電路板。該稜鏡將穿過透鏡入射的光,分離成至少兩個顏色,並輸出該光。該第一及第二成像裝置每一個藉由光電轉換該光以產生視訊信號。該類比/數位轉換器將輸出自該等每一個裝置的該視訊信號,轉換成數位信號。該時序產生器產生視訊信號處理時脈,用以驅動該第一成像裝置、該第二成像裝置、及該類比/數位轉換器。該第一成像裝置安裝在該第一電路板上。該類比/數位轉換器及該時序產生器安裝在該第二電路板上。該第二成像裝置安裝在第三電路板上,並經由纜線連接至該第一電路板及該第二電路板。2‧‧‧透鏡區塊2a‧‧‧連接器200‧‧‧成像區塊30‧‧‧分色稜鏡10‧‧‧透鏡安裝基座11B‧‧‧成像裝置10a‧‧‧定位孔31‧‧‧窗口40A,40B,40G,40R‧‧‧電路板41‧‧‧軟性纜線60‧‧‧電力去耦電容器
