本人使用的是Hi3516CV300+IMX291，进过调试，发现输出图像整体偏紫色，请问论坛里面有没有人遇到这种情况？PS：我有使用IRCUT，应该不是有无IRCUT的问题。

我也尝试打开过白平衡，发现效果也是一样的

ISP 的Bayer 序列不正确。

黑电平和isp的bayer序列可以先确认下是否配置无误。

嗯嗯，谢谢您的回复，是isp的bayer序列有问题的。

我这lvds蓝屏，这是啥情况？？求指导下，大神。。
1.根据数据手册修改 mpp\component\isp\user\sensor\hi3519av100\sony_imx291 这个编译出来的是libsns291.a和libsns291.so ，改为lvds
2.SDK里有个sample文件夹，里面有个vio范例，修改里面的结构体参数，比如
ISP_PUB_ATTR_IMX291_4K_30FPS
MIPI_4lane_CHN0_SENSOR_IMX291_12BIT_1080p_NOWDR_ATTR
DEV_ATTR_IMX291_1080p_BASE
主要是改分辨率和帧率，其中MIPI_4lane_CHN0_SENSOR_IMX291_12BIT_1080p_NOWDR_ATTR这个结构体要大改
input_mode = INPUT_MODE_MIPI,要修改成input_mode = INPUT_MODE_LVDS

这个lvds的驱动配置有问题吗？？？？
void imx291_linear_1080p30_init_lvds(VI_PIPE ViPipe)
{

说实话，海思自带的imx290的驱动可直接用于imx291，我记得我对于驱动的更改很少，只是设置了一下sensor为LVDS模式
