US7,417,664
專利揭露一種根據光學軸交叉點資訊的立體影像取得與顯示系統(Stereoscopic image picking up and display system based upon optical axes cross-point information),影像取得裝置包括兩個影像取得裝置分別輸出影像到立體影像顯示器,裝置並計算其中光軸交叉點(cross-point, CP),而此顯示器包括偏移(offset)預設裝置,可以偏移影像,使得可以同時顯示兩個根據光軸偏移的疊影。
其中示意圖顯示有兩個攝影機(402R, 402L)同時拍攝一個物體,之後計算光軸交叉點,其中利用超音波偵測取得觀看人的位置,光軸是人眼到顯示器表面的連線,顯示控制電路中的偏移預設電路將兩個影像執行偏移,最後呈現在顯示器的影像有一視差,可以分別在兩個眼睛成像產生立體效果。
下圖示意顯示顯示器結構:3是Fresnel lens、7是圖案化的過濾器、2是液晶面板、5是光源、6是偏光過濾器:
兩個影像透過偏移手段產生一個偏移量。
顯示器後端有兩個影像輸出(影像取得裝置),因此經過顯示會有兩個影像,分別投射到人眼。
專利範圍可以看出整個技術核心再於系統有包括兩個影像取得手段的裝置、顯示立體影像的顯示器、傳輸影像的媒體,重點在從輸出影像計算出光軸的交叉點,再偏移與顯示兩個不同的影像,藉此產生裸視3D影像。
1. A stereoscopic video image pick-up and display system comprising:
- a stereoscopic video image pick-up device including two video image pick-up means for outputting video information from said pick-up means;
- a stereoscopic video image display device for displaying different video images for the eyes of a viewer; and
- a medium for transmitting video image information from said stereoscopic video image pick-up device to said stereoscopic video image display device,
- in which said stereoscopic video image pick-up device includes cross-point measuring means for measuring CP information on the cross-point (CP) of optical axes of said pick-up means and outputs information including the CP information and video image information to said medium; and
- in which said stereoscopic video image display device includes offset presetting means for offsetting and displaying said different video images based upon said video image information, said cross-point information and information on the size of the image which is displayed by said stereoscopic video image display device.
最後宣告侵權成立,甚至是故意侵權,這對正在與手機遊戲廝殺且可能處於下風的任天堂來說,顯然是個天大的打擊。(任天堂還可上訴)
