Our image sensor cannot generate voltages higher than 2.8V. However, it is designed to support I2C communication at voltages ranging from 1.8V to 3.3V.
The red X mark indicates that the Raspberry Pi does not supply power to the camera, so it is not connected to any camera pins. Thank you for your assistance.

Previously, we removed the pull-up resistors on the camera module and tested again, but communication still did not work. The real issue turned out to be the confusing manual that even you mentioned.
The 7-bit slave address is not 0x36, but rather 0x1b, and when using this, it worked correctly. Of course, the pull-up resistors on the camera module were removed.
Now, the remaining tasks are to deliver the reset signal using pin 11 of the camera input connector and supply power to the camera from the Raspberry Pi. Do you happen to know how much current the Raspberry Pi 4 Model B can supply to the camera at 3.3V? For reference, our camera module consumes approximately 300mW.
My best regards,
