Video Capture

基本解釋

Before I get into the details of video-capture devices, a little background on the technology is in order.
在深入視頻采集設(shè)備的細(xì)節(jié)之前，先說一點技術(shù)背景資料。

In order to explain the video-capture interface I will use the example of a camera that has no tuners or audio input.
為了更好的解釋視頻采集接口，我采用了一個沒有接收機(jī)和沒有音頻輸入的攝像頭作例子。
This relieves the processor from doing the work but does require some intelligence on the part of the video-capture chip, as well as a suitable video card.
這減輕了處理器的壓力，但是需要視頻采集芯片具有一定智能，而且還要合適的視頻卡。

U.S.Defense Secretary Robert Gates had only this to say today about the capture of 23-year-old U.S.Army Private Bowe Bergdahl and the video the Taliban apparently forced him to make.

Naturally, HDR stills are also possible -- and it's not the first phone that has HDR video -- but the feature should offer up improved video capture, namely less washed-out skies and improved low-light video.

Hardware-wise, there's a 1.2GHz Snapdragon 200 quad-core processor, with a 4.5-inch Super LCD2 display (at 960 x 540 resolution), an 8-megapixel primary camera capable of up to 720p video capture and a front-facing 1.6-megapixel shooter.

視頻采集
Video Capture and Compressing System Based on DSP belongs to high speed circuit.
基于DSP的視頻采集壓縮系統(tǒng)屬于高速電路的范疇。
視頻捕獲
A video capture system accessing to buffer directly is designed.
開發(fā)了視頻捕獲系統(tǒng)，實現(xiàn)了視頻數(shù)據(jù)的直接內(nèi)存訪問。
圖像采集
Then the study on technique of video capture based on windows platform is discussed, and applies it to collect the microscopic image.
其次，論述了基于Windows平臺的視頻捕捉技術(shù)研究并將其應(yīng)用于顯微圖像采集。
視訊擷取

視頻采集
Secondly, a video capture control system is realized based on FPGA.
然后本文探討和實現(xiàn)了基于FPGA的視頻采集控制系統(tǒng)。
視頻捕獲
Together with the video part (including video capture、codec and playback), this system can be used in any video conference system.
本系統(tǒng)可以與視頻處理部分（包括視頻捕獲、編譯碼以及回放）相結(jié)合，構(gòu)成一個完整的視頻會議系統(tǒng)。
