GitUp Git2 Hot Pixel removing (sensor calibration)
1. Upgrade the firmware to the latest version and ensure the camera has a fully charged battery.
2. Create a new text file in the root folder of the Micro SD card and name it "engmode" without an extension.
3. Turn on the camera using the Power button, the following interface will be displayed. First please choose the #0 to format SPI and confirm the operation pressing the SHUTTER button, then back to this interface.
4. Using the camera Power button (MODE) for navigation, move to the third option DP Bright Adjust, first point camera to something white with lots of light (avoiding shadows) and press SHUTTER button, wait for the message “Press OK KEY to continue” to be shown on the screen, cover the lens with full black in a dark room and wait 10 minutes (20-30 recommended) for the sensor temperature to stabilize, then press the Shutter button and wait for the following message to be shown on the screen, the bright pixel calibration is then complete.
5. Then, using the Power button (MODE), choose the fourth option DP Dark Adjust, first point the camera to a completely white image, for example an LED flashlight seen through white paper. Please make sure the camera is seeing full white with no shadows. Then press the Shutter button and keeping the camera steady and oriented to the white object wait for the following screen to be displayed, the dark pixel calibration is then complete:
6. Using the Power button, turn off the camera, take out the Micro SD card and delete the “engmode” file using a computer.
The Git2 image sensor is now fully calibrated which should result in minimal warm/hot pixels on video recorded in low light conditions. Remember that this is an analog sensor, it will be impossible to achieve 100% perfection and the sensor accuracy will change with temperature, but the calibration should remove any annoying warm/hot pixels from video recorded in low light conditions.
If you are not satisfied with the result, you can do it again, but remember to format the SPI first. And we recommend you heat up the camera more than 30 minutes before fixing hot pixel to get better result.
