MV系列和RAW系列MIPI摄像机模组寄存器列表

1 概述

1.1 寄存器特征

寄存器地址的长度为4字节，值的长度为2字节。

寄存器读写属性分为RW，RO，WO三种。只有RW属性的可以保存到摄像机flash中。

寄存器值包括几种类型：int，bool，enum，ascii。

1.2 i2c通信协议

模组支持通过i2c协议进行参数配置。摄像机默认的i2c从地址是0x3b,这个地址是可以修改的。

i2c读写寄存器时采用大端字节序，即高字节在前的顺序。

为了方便客户使用，我们提供了linux下开源的shell脚本，帮助进行每个寄存器的读写。

下表中script function一列表示此寄存器对应的shell脚本的功能函数。

1.3 Update timing

摄像机有两种状态，standby和running。上电后进入standby状态，开始图像采集后进入running状态。

下表中，Update timing的类型有：
A：任何时刻都可以读写。

S: running状态下可读不可写。

-：任何时刻都只读。

1.4 Raw series Support

RAW系列摄像机的功能是MV系列摄像机的子集。

它包含一个sensor和一个MCU，MCU用于sensor模式的配置和外触发的延迟。

特别的，它支持Sensor Direct Access模式。在此模式下，MCU放弃对sensor的控制和操作，开放sensor的i2c给客户直接控制。MCU只保留极少必要的寄存器功能。

N：不支持。

S：普通模式下支持。

SDA：Sensor Direct Access模式下支持。

Note1: All parameters of exposure time are in microseconds. However, due to the properties of the sensor, the actual exposure time unit of the sensor is 1 line, can not be accurate to 1us.

Note2：For all gain-related parameters, the register value is 10 times the number of dB. For example, if the register is 101, it means 10.1dB. The range and step vary according to the model.

Note3: AE: Auto exposure; AG: Auto Gain; AA: AE and AG.

Note4: The AAROI coordinates are relative coordinates within the roi range.
