MTK Android Driver ：camera

1.相关代码位置：
mediatek\config\XXXX（红色字为具体的项目名）

文件：ProjectConfig.mk

CUSTOM_KERNEL_IMGSENSOR = …… gc2235_raw

CUSTOM_KERNEL_MAIN_IMGSENSOR = …… gc2235_raw

CUSTOM_HAL_IMGSENSOR = …… gc2235_raw

CUSTOM_HAL_MAIN_IMGSENSOR = …… gc2235_raw

kernel:

\mediatek\custom\common\hal\imgsensor\gc2235_raw

mediatek\custom\common\kernel\imgsensor\src

文件：kd_sensorlist.h

添加内容：

UINT32 GC2235SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc);

ACDK_KD_SENSOR_INIT_FUNCTION_STRUCT

kdSensorList[MAX_NUM_OF_SUPPORT_SENSOR+1] =

{

#if defined(GC2235_RAW)

{GC2235_SENSOR_ID, SENSOR_DRVNAME_GC2235_RAW, GC2235SensorInit},

#endif

};

mediatek\custom\common\kernel\imgsensor\inc

文件：kd_imgsensor.h

添加内容：

#define GC2235_SENSOR_ID                 0x2235

#define SENSOR_DRVNAME_GC2235_RAW    "gc2235"

hal

\mediatek\custom\common\hal\imgsensor\gc2235_raw

mediatek\custom\common\hal\imgsensor\src

文件：sensorlist.cpp

添加内容：

MSDK_SENSOR_INIT_FUNCTION_STRUCT SensorList[] =

{

…………

#if defined(GC2235_RAW)

RAW_INFO(GC2235_SENSOR_ID, SENSOR_DRVNAME_GC2235_RAW, NULL),

#endif

…………

};

在 kdSensorList 和 SensorList 里面添加驱动的时候要注意，Sensor添加的位置要一样。否则驱动会跑乱，轻则 ISP 参数不对，重则Sensor 无法启动。

2.拍照图片尺寸设置：

..\mediatek\custom\prj\hal\camera\camera\cfg_ftbl_$prj$_raw_main.h

//Capture Size

CONFIG_FEATURE(FID_CAP_SIZE,

BY_DEFAULT(CAPTURE_SIZE_1600_1200),

/*BY_DEFAULT(CAPTURE_SIZE_2560_1920), benmodify*/

CAPTURE_SIZE_640_480,

CAPTURE_SIZE_1280_960,CAPTURE_SIZE_1600_1200,

)

3.Camera物理角度旋转

90度：\alps\mediatek\custom\$prj$\hal\imgsensor\src\cfg_setting_imgsensor.cpp

static SensorOrientation_T const inst = {

u4Degree_0  : 180,//90,  //  main sensor in degree (0, 90,180, 270)

u4Degree_1  : 0,//90,   //  sub  sensor in degree (0, 90, 180, 270)

180度：
Sensor FAE提供修改方法。

4.Camera 相同sensor id兼容方式（前后sensor id一致）：

//配置区分：

CUSTOM_KERNEL_IMGSENSOR = gc0308_yuv# gc0308_sub_yuv

CUSTOM_KERNEL_MAIN_IMGSENSOR =gc0308_yuv # gc0308_sub_yuv

CUSTOM_HAL_IMGSENSOR = gc0308_yuv# gc0308_sub_yuv

CUSTOM_HAL_MAIN_IMGSENSOR = gc0308_yuv# gc0308_sub_yuv

//kernel:函数名也要区分

\alps\mediatek\custom\common\kernel\imgsensor\gc0308_sub_yuv

\alps\mediatek\custom\common\kernel\imgsensor\gc0308_yuv

//hal: 函数名也要区分

\alps\mediatek\custom\common\hal\imgsensor\gc0308_sub_yuv

\alps\mediatek\custom\common\hal\imgsensor\gc0308_yuv

//kdSensorList 和 SensorList里面添加驱动也要区分，sensor id不要区分，写成一致，根据前后摄像头开关代码区分。

#defineGC0328_SENSOR_ID       0x009D

#defineGC0328_SUB_SENSOR_ID   0x9D9D
