想用at91sam9g45做视频采集,但不知道它的ISI(Image Sensor Interface)接口能采集到的帧速是多少?
手册上说帧速太快时可能会有丢帧的现象,但具体是多少呢?30fps的PAL信号能够采集吗?
The ISI Codec path is disabled after the capture of each frame and so requires to be enabled
before the capture of the next frame. This may lead to discarding some frames if the frame rate
is high. |
