@alex_ai First, let me explain the gain configuration logic for the GX-MIPI-IMX662. The IMX662 features 30dB of Analog Gain and supports High Conversion Gain (HCG). The HCG function acts as an amplification during the sensor's analog signal readout, equivalent to 15.3dB. Therefore, when we configure the "Again" parameter, the actual range is [0, 45.3dB]. This means you can set the Analog Gain up to 45dB without enabling Digital Gain (Dgain). Currently, our firmware integrates HCG into the "Again" setting, which may have caused some confusion during your testing. As for the feature to read sensor registers, I have added it to the development roadmap. It will be provided later via a firmware update package.

@alex_ai said in IMX462M pixelformat on RPi5: I need wait for clear sky to test and provide feedback Finally tested, for gain value 20 it is looks pretty same with color sensor with ISP, but background no so black as for color sensor. For me this issue resolved, attached examples to compare (10 seconds stacks) IMX462 mono [image: 1723360275505-imx462m_small.jpg] IMX462 color with ISP [image: 1723360306335-imx462c_small.jpg]

@alex_ai Sorry, we currently don't have plans to proceed with the development of this sensor.
