一mtk修改对焦模式
1.log中搜索SensorId知道对应 SensorId
LensMCU : LensMCU[isSupportLens][CurrSensorDev]0x0001 [CurrSensorId]0x1241
2.根据SensorId(如0x1241)从kernel中知道对应的宏名称OV12A10MIPI_SENSOR_ID
[email protected]:~/codes/mtk_8.1_6763_baseline_for_GomeMultiScan/kernel-4.4/drivers/misc/mediatek/imgsensor$ grep -rni "0x1241" ./
./src/mt6763/ov12a10_mipi_raw/ov12a10mipiraw_Sensor.c:914:static kal_uint32 return_sensor_id(void) // jack_yan 0x1241
./inc/kd_imgsensor.h:190:#define OV12A10MIPI_SENSOR_ID 0x1241
3.根据sensor宏名称从vendor中查找对应的参数配置目录ov12a10_mipi_raw/,在目录中搜索MTK_CONTROL_AF关键字设置相关对焦配置
通过上述驱动配置找到对应的sensor
/codes/mtk_8.1_6763_baseline_for_GomeMultiScan/vendor/mediatek/proprietary/custom/mt6763/hal/imgsensor_metadata/ov12a10_mipi_raw
查找所有配置自动对焦模式的地方,修改自动对焦模式
CONFIG_METADATA_BEGIN(MTK_CONTROL_AF_MODE)//(pre:auto)
CONFIG_ENTRY_VALUE(MTK_CONTROL_AF_MODE_OFF, MUINT8)
config_request_metadata__.h
搜MTK_CONTROL_AF
4.修改后编译
编译hal默认配置参数路径
A:\codes\mtk_8.1_6763_baseline_for_GomeMultiScan\vendor\mediatek\proprietary\hardware\mtkcam\utils\metastore
二.如何判断当前预览或者拍照,走的tuning profile是否正常
1
adb shell setprop debug.paramctrl.enable 1
adb shell setprop debug.isp_debug.enable 1
2.
logcat | grep -i "isp_tuning_idx"

3.grep -rni "define DBS" ./
找到对应DBS配置
/vendor/mediatek/proprietary/custom/mt6763/hal/imgsensor/ver1/ov12a10_mipi_raw$ grep -rni "define DBS_0001"
camera_isp_regs_preview_ov12a10mipiraw.h:135:#define DBS_0001 /*profile = Preview, sensor = Preview, ISO_1*/{{
三。mtk修改支持的拍照尺寸
1.log中搜索SensorId知道对应SensorId
LensMCU : LensMCU[isSupportLens][CurrSensorDev]0x0001 [CurrSensorId]0x1241
2.根据SensorId(如0x1241)从kernel中知道对应的宏名称OV12A10MIPI_SENSOR_ID
3.搜索config.ftbl*找到如下路径文件config.ftbl.ov12a10_mipi_raw.h
/vendor/mediatek/proprietary/custom/mt6763/hal$ find ./ -name config.ftbl*
./sendepfeature/ov12a10_mipi_raw/config.ftbl.ov12a10_mipi_raw.h
4.打开config.ftbl.ov12a10_mipi_raw.h,搜索KEY_PICTURE_SIZE即对应配置的支持的拍照尺寸列表
四 log打印会退出处理方法?
修改logd打印容量 diff如下
/device/gome/gm18a$ git diff
diff --git a/device.mk b/device.mk
index 61d9e6a..4930c9a 100644
--- a/device.mk
+++ b/device.mk
@@ -163,3 +163,4 @@ PRODUCT_BRAND := GOME
PRODUCT_MANUFACTURER := GOME
PRODUCT_PROPERTY_OVERRIDES += ro.build.display.factoryid=$(strip $(MTK_BUILD_FACTORYID))
+PRODUCT_PROPERTY_OVERRIDES += ro.logd.size=16M
五 录屏功能
screenrecord --size 1280x720 --time-limit 60 sdcard/weixin.mp4
六.mtk判断微信是否走turning效果
请在复现问题前,输入如下adb命令,这样可以在log中实时打印出当前帧所用到的的ISP index,可搜索关键字“isp_tuning_idx”。
adb shell setprop debug.paramctrl.enable 1
adb shell setprop debug.isp_debug.enable 1
七.mtk 打印更多debuglog
请进camera之前输入:抓取更多log
adb shell setprop debug.camera.log 3
八.mtk hal中修改配置的摄像头安装角度
vendor/mediatek/proprietary/custom/mt6763/hal/imgsensor_src/cfg_setting_imgsensor.cpp
其中u4Degree_1设置前摄的安装角度,若果预览不正常可以尝试修改角度值
getSensorOrientation()
{
static SensorOrientation_T const inst = {
.u4Degree_0 = 90, // main sensor in degree (0, 90, 180, 270)
.u4Degree_1 = 270, // sub sensor in degree (0, 90, 180, 270)
.u4Degree_2 = 90, // main2 sensor in degree (0, 90, 180, 270)
.u4Degree_3 = 90, // sub2 sensor in degree (0, 90, 180, 270)
};
