I have problem in the demo of isp_ov10640_quad, I use four ov10640 camera (with isp) in our system and I want to use isp_ov10640_quad demo, so what should I do to make it work? Look forward to your reply ,Thank you!
The problem which color is not correct, may be cause by the below factor:
1.please check the camera or max9286 register configure value.
2.the lcd display format is UYVY, but your camera data may be YUYV, so you should get the image and chect it in computer, if your image is correct, then you should change the YUYV data to UYVY when in display.
已经解决了,使用了ov10635的demo来修改,将graph里面的引擎改成ov10640,重新编译替换sdk里面的graph,然后就工作正常了。
