車載顯示器專用影像處理IC

雙/單畫面視頻處理器

產品介紹

東芝公司的車用雙畫面視頻處理器配置了集成幀記憶體,因此可以同時顯示兩個獨立的畫面。此外,晶片上的記憶體記憶體允許導航系統的圖形資料覆蓋視頻信號。東芝公司的視頻處理器,支援各種類比和數位視頻格式,並允許根據液晶面板的分率來優化調整圖片。其輸出端階段的配置有適用於不同品牌液晶面板的時序控制晶片。T-CON適用於多個液晶面板製造商生產的LCD面板。

產品介紹

全面、多標準視頻解碼器: TC90104AFG

TC90104AFG是一款全面、多標準的視頻解碼器IC,它不僅支援C視頻輸入,而且支援D1和D2分量輸入。TC90104AFG提供動態YC伽瑪校正以及基帶色彩功能用於畫質提升,基帶色彩功能能夠實現所有視頻格式的色彩調整,使其達到D2解析度。 除了ITUR-656輸出介面之外,還為D2視頻輸入提供一個備選的8位元串行輸出,同時時鐘頻率從27MHz轉變成54MHz。

這是全面、多標準視頻解碼器, TC90104AFG的方框圖。

雙通道多標準視頻解碼器IC: TC90105FG

TC90105FG是一款雙通道視頻解碼器,其特點是具有調整各種畫面品質的功能。例如HV和對角線增強(HVD)、色彩管理和動態YC伽瑪校正。用戶可以根據汽車攝像頭拍攝的視頻進行圖像渲染。

HVD增強:除了提供傳統的橫向和縱向邊緣增強之外,還提供對角線邊緣增強。TC90105FG的HVD增強功能在應用大量邊緣增強的同時最大程度地減少人工處理的痕跡。
色彩管理:能提高所選色彩的飽和度。其目的是通過創造出獨特的色彩(例如使紅色更加醒目),提高其可視性。TC90105FG允許用戶選擇三種顏色並規劃其所需的飽和度。
動態YC伽瑪校正:通過優化調整伽瑪校正曲線獲取最佳的圖像亮度,控制黑白色的衰減以提高可視性。基於亮度伽瑪校正,通過調整色度增益,TC90105FG可保持亮度和色度之間的平衡。
