with problem in isp_ov10640_quad demo

[huangzhong]

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!

我这边干掉了初始化ov10640的相关代码，修改了max9286和 max96705的初始化代码。发现在图像有翻滚，以及图像颜色不对的情况 。

[huangzhong]

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.

请问你们的camera（ov0640）是哪里获取的？是NXP提供的嘛？你们ov0640的配置通过什么配置的？

[yong_qian]

同问，camera是从哪里获取的，带的isp是ov490吗，还需要使用soc上的isp吗

[liyu1]

你好！请问能不能将MAXIM_OV10640_InitComplex 您那边设置的值发给我参考一下。不甚感激

[yunlongyu]

你好，请问你们用的ov10640的camera是哪里获取的？

[liyu1]

你好。。我们也在用s32v234  ov10640 带isp环视。请问这个问题你解决了吗。如果没有解决。。咱们可以一起解决。我QQ：542270618

[huangzhong]

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。

我和你使用了相同的demo ,你应该也是在调带ISPov10640 max9286 的四拖一的板子吧？我也正在调这部分,可以一起探讨 QQ：435761040

[liyu1]

你好。请问您这边修改了关于max9286 和96705的相关代码吗？

请问你们有ov10640 camera提供吗，是否带isp，带的isp是ov490吗，如果带isp，还需要使用soc上的isp吗，谢谢

[bigwater]

请问，你是ov10640&ov490吗？有调试成功吗？能否分享一下
