2014-03-20 03:12:35 -0600 | asked a question | “linear” noise in frames captured from analog camera. I am trying to capture the frame from analog camera using VS13, OpenCV and AverMedia DVD EZMaker 7. If i make a simple cycle like i get a frame, but the frame has a noise like this: This lines appears if it has a dynamic object on the frame. However i was trying to capture a camera using Media Player Classic. And i had two types of output images. First image had the same noise. But when i changed (in MPC) a format from "RGB24" to "YUVU" i have a better result My question: How can i fix this trouble? I want to capture a correct frame without lines. P.s. Also i tryed to use VideoInput library in my program, but it didn't help. The frame was with noise. I used this code to capture: P.P.s: When i used a cvCvtColor operator (OpenCV or VideoInput): cvCvtColor(frame, frame2, CV_RGB2YUV); cvShowImage("My window", frame2); i had an incorrect color reproduction. //and noise When i created an image using IPL_DEPTH_16U (VideoInput) i had an incorrect color reproduction, i had 2 images in window, but that images shown without noise. P.p.p.s. Sorry for my bad english. I think, i have a lot of mistaker in my grammar. But i hope that i accessibly explain the problem. |
