初来贵坛 拜拜山头 最近搞安森美的图像 sensor

现在有个项目，需要用安生美的图像传感器，AR0144，

使用其自带的AEC来控制曝光，所以如有用过或想用该sensor的坛友，欢迎讨论

Auto Exposure
The integrated automatic exposure control (AEC) is responsible for ensuring that
optimal settings of exposure and gain are computed and updated every other frame.
AEC can be enabled or disabled by R0x3100[0]. When AEC is disabled (R0x3100[0] = 0),
the sensor uses the manual exposure value in the coarse and fine integration time registers
and the manual gain value in the gain registers. When AEC is enabled
(R0x3100[0]=1), the target luma value is set by AE_LUMA_TARGET_REG (R0x3102). For
AR0144, this target luma has a default value of 0x0500. The luma target maximum auto
exposure value is limited by R0x311C; the minimum auto exposure is limited by
R0x311E. These values are in units of line-times. The minimum value for register 0x311E
is 1 line. The exposure control measures current scene luminosity by accumulating a
histogram of Gr pixel values while reading out a frame. It then compares the current
luminosity to the desired output luminosity. Finally, the appropriate adjustments are
made to the exposure time and gain.
