摘要
摘要 本篇論文目標為了改善當前使用的類比車載攝影機，研究開發下一世代車用市場車載攝影機系統做研究改善，本研究選用LVDS影像傳輸系統技術，其目的在於改善當前類比傳輸系統影像解析度低的問題。車載攝影機於汽車市場上已經是標準配備，最常被使用於倒車影像系統，應用監控車後影像行駛安全，近年全周影像行車補助系統，應用於車輛四周監控影像建立，佈建於車輛四周的四顆鏡頭，使用影像感測器晶片內建類比傳輸技術(NTSC、PAL)，將四路影像傳輸至中控平台;如上述說明倒車影像系統、全周影像行車補助系統皆需要將攝影機影像透過長距離傳輸到中控平台做影像處理，而傳統類比影像規格為VGA解析度(640*480)。本研究計畫是使用一對LVDS，傳輸影像感測器晶片影像訊號，利用LVDS傳輸介面可達到長距離傳輸資料符合YUV422 10bit數位影像格式，達到研究需求影像HD解析度(1280*720)。 關鍵字 : 低壓差動訊號、車載攝影機、行車補助系統、影像感測晶片。

Abstract This object of thesis is to improve the current automotive cameras. So I study and focus on how to improve the car camera system in next generation car market. I choose LVDS image transmission system technology, and the purpose is to improve the current image resolution problem of analog transmission system. This is standard and popular equipment in the market where the car camera is installed on the vehicles. Current the popular application is used on Reversing Image System to monitor the safety of driving. In the recent years, Around View Monitor System (AVM) is used to monitor around the vehicles. In general, the car built-in 4 analog cameras (NTSC/PAL) to transmit the four channels of images to the central control platform. According to Around View Monitor System and Reversing Image System, all need to transmit the camera image to the central control platform for image processing by long distance transmission. The image transmission specification is VGA resolution (640*480). In order to improve image resolution problem, this research will be used one pair of LVDS to transmit the image, and use the LVDS transmission interface to achieve long-distance transmission of data. It conforms to the YUV422 10bit digital image format and achieves the HD resolution (1280*720). Keywords: LVDS; Automotive Cameras; AVM; CMOS Image Sensor.
