Camera Colorimeter uses a back-facing camera as a colorimeter to color calibrate a Windows device running 

Display Calibration

Communication between Camera Colorimeter and the external device is via Bluetooth.

FEATURES

- Produces an ICC profile which can then be installed on the PC
- Uses RAW_SENSOR data on capable phones for most accurate color metering
- Option for calibrating your camera by capturing a reference D65 white point and primary RGB colors
  

REQUIREMENTS

- Android 5.0 (Lollipop) or higher
- Bluetooth
- A good quality back-facing camera with DAYLIGHT (D65) white balance and manual exposure controls

**A camera device that supports RAW_SENSOR image capture is highly recommended**

OPTIONAL REFERENCE WHITE

The accuracy of color readings made by Camera Colorimeter can be improved if it is provided with a reference D65 light source.  This is done by placing the back-facing camera over the D65 light source and select "Capture white point" from the menu.    See below for how to use sunlight as an approximate reference D65 light source.

Accuracy can best be improved by providing reference sRGB white (D65), red, green and blue primaries.  These must be obtained from the same source, at the same brightness settings.  

INSTRUCTIONS

Instructions for color calibrating a Windows device is given within the Display Calibration app itself.

It is important that the Camera Colorimeter app must remain active in the foreground.  Do not put the device to sleep or start another app otherwise the calibration process will need to be repeated.

Calibration takes about 5 - 10 mins so be sure that both devices have sufficient battery capacity to complete the operation.

BLUETOOTH PAIRING

It is essential to have this Camera Colorimeter app running when pairing your phone with your PC.  If you have already paired your devices then please delete and re-create the pairing after running the Camera Colorimeter app.

WINDOWS CONNECTION PERMISSION 

Upon connecting this Camera Colorimeter app on your phone and our Display Calibration app on your PC for the first time, Windows will present a dialog box asking for permission to connect the two devices/apps.  Please click "Yes".  

If you don't see this dialog box and your devices fail to connect, please uninstall and re-install the Display Calibration app on your PC.

LIMITATION

This app calibrates your display to the standard sRGB colour space.  Wider colour spaces are currently not supported.

Due to the limitation of the ICC profiles used by Windows, some displays can not be adequately calibrated.  These are typically displays whose colours have been highly tweaked by the manufacturer.  

It is essential to adjust the colour settings on your display to Standard, sRGB, or 6500K prior to calibration.  Please do not select tweaked colour settings such as Gaming, Cinema, etc...

APPROXIMATE REFERENCE D65 LIGHT SOURCE

Sunlight at mid-day on a sunny day can be used as an approx. D65 light source, as follows:

- Tape a white piece of paper over the camera lens of device A
- Ensure that the piece of paper is in direct sunlight, but do not point the camera directly at the sun
- Select "Capture white point" from the menu.
- Uncover the camera lens
