答案对人有帮助，有参考价值 0 Platform: RK3288 OS: Android 6.0 Kernel: 3.10.92 需求：摄像头安装之后预览和预览回调画面是倒着的，需要旋转180°。现象：通过修改camera_board.xml中的参数，发现只有预览画面正常，而预览回调数据还是倒过来的。说明此参数只对预览有效。解决方法：通过修改模组寄存器的flip参数。代码改动： diff --git a/Config/cam_board_rk3288.xml b/Config/cam_board_rk3288.xml index d3ea5bc..279a9c7 100644 --- a/Config/cam_board_rk3288.xml +++ b/Config/cam_board_rk3288.xml @@ -21,7 +21,7 @@ - + diff --git a/SiliconImage/isi/drv/OV5640/source/OV5640_tables.c b/SiliconImage/isi/drv/OV5640/source/OV5640_tables.c index a8e25f3..dfe58c4 100755 --- a/SiliconImage/isi/drv/OV5640/source/OV5640_tables.c +++ b/SiliconImage/isi/drv/OV5640/source/OV5640_tables.c @@ -71,7 +71,7 @@ const IsiRegDescription_t OV5640_g_aRegDescription[] = {0x3c09, 0x1c,"",eReadWrite,}, {0x3c0a, 0x9c,"",eReadWrite,}, {0x3c0b, 0x40,"",eReadWrite,}, - {0x3820, 0x41,"",eReadWrite,}, + {0x3820, 0x47,"",eReadWrite,}, {0x3821, 0x07,"",eReadWrite,}, {0x3814, 0x31,"",eReadWrite,}, {0x3815, 0x31,"",eReadWrite,}, @@ -300,7 +300,7 @@ const IsiRegDescription_t OV5640_g_aRegDescription[] = {0x3503, 0x00,"",eReadWrite,}, {0x3c07, 0x08,"",eReadWrite,}, - {0x3820, 0x41,"",eReadWrite,}, + {0x3820, 0x47,"",eReadWrite,}, {0x3821, 0x07,"",eReadWrite,}, {0x3814, 0x31,"",eReadWrite,}, {0x3815, 0x31,"",eReadWrite,}, @@ -351,7 +351,7 @@ const IsiRegDescription_t OV5640_g_svga[] = {0x3503, 0x00,"",eReadWrite,}, {0x3a00, 0x7c,"",eReadWrite,}, {0x3c07, 0x08,"",eReadWrite,}, - {0x3820, 0x41,"",eReadWrite,}, + {0x3820, 0x47,"",eReadWrite,}, {0x3821, 0x07,"",eReadWrite,}, {0x3814, 0x31,"",eReadWrite,}, {0x3815, 0x31,"",eReadWrite,}, @@ -411,7 +411,7 @@ const IsiRegDescription_t OV5640_g_video_720p[] = {0x380f,0xe4,"",eReadWrite,}, {0x3813,0x04,"",eReadWrite,}, - {0x3820, 0x41,"",eReadWrite,}, //ddl@rock-chips.com add start: qsxvga -> 720p isn't stream on + {0x3820, 0x47,"",eReadWrite,}, //ddl@rock-chips.com add start: qsxvga -> 720p isn't stream on {0x3821, 0x07,"",eReadWrite,}, {0x3814, 0x31,"",eReadWrite,}, {0x3815, 0x31,"",eReadWrite,}, @@ -449,45 +449,45 @@ const IsiRegDescription_t OV5640_g_video_720p[] = }; const IsiRegDescription_t OV5640_g_2592x1944[] = { - {0x3820, 0x41,"",eReadWrite,}, + {0x3820, 0x47,"",eReadWrite,},
