          @veye_xumm, I see lot of methods in RaspiCamControl.c file that seem to control contrast (raspicamcontrol_set_contrast), saturation and lot of others parameters for the camera.
          Can I use them to set VEYE_MIPI_IMX462 parameters rather than using I2C shell scripts ? It would be more convenient.

          Thanks for your help

            Hi，
            I think it could not work.
            RaspiCamControl.c control the isp moudle inside RPI, while VEYE camera use ISP outside RPI.

              Thanks for your reply. Can you also tell me if you have some help regarding the I2C registers of the camera. The VEYE shell script is well documented for value of register 0x12 but nothing about 0x10, 0x11 and 0x13 registers and values.

                There are multiple modules inside the camera, and these registers are set to access multiple modules through an i2C address.
                Customers need to strictly follow the function of the shell script to access a full function.

                  Sorry again for all this questions and thanks a lot for your great help. My last question is regarding the picture format. Is RGB format available ?
                  I add a IMAGE_ENCODING_RGB FOURCC('R', 'G', 'B', '') in D_mipicam.h . So if I create an IMAGE_FORMAT with this value for encoding member, will it be enough ?

                    NO.
                    This camera module support YUV422(VYUY or YUYV) only.

                              Just one more question regarding this format, how can I know that it is VYUY or YUYV. It is important because I want to convert to RGB and the converting algo is not the same.
                              I you ever have a python piece of code to convert the buffer.as_array returned numpy array to RGB numpy array it would be a great great help for me !!

                              Thanks
