MV Series and RAW Series MIPI Camera Register Map

1 Overview

1.1 Register Features

The register address length is 2 bytes and the value length is 4 bytes.

Register R/W attributes: RW, RO, WO. Only the RW type can be saved to the camera flash.

Register values have several types: uint（unsigned int）, bool, enum, ascii.

1.2 I2c communication protocol

The module supports parameter configuration via i2c protocol. The default i2c slave address of the camera is 0x3b which can be modified.
I2c data input order is MSB-first transfer.

We provide open source shell scripts under Linux to help read and write each register.

The script function column in the following table indicates the function name in the shell script corresponding to this register.

1.3 Update timing

The camera has two states, standby and running.

After power on, it enters the standby state, and after starting image acquisition, it enters the running state.

In the following table, Update timing possible value is:

A: Read and write at any time.

S: Read only at running state.

-: Read only at any time.

1.4 Raw series Support

The RAW series camera functions as a subset of the MV series camera.

It contains an MCU, which is used for sensor mode configuration and external trigger delay.

In particular, it supports Sensor Direct Access mode. In this mode, the MCU gives up the control and operation of the sensor, and opens the i2c of the sensor to the customer for direct control. The MCU only retains very few necessary register functions.

N：Not support.

S：Support in normal mode.

SDA：Support in Sensor Direct Access mode.

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 area. So the area must be smaller than the image ROI.
