Camera Colorimeter [free]


Camera Colorimeter uses a back-facing camera as a colorimeter to color calibrate another Android or Windows device running
Calibrated Photo Viewer
or Display Calibration
Communication between Camera Colorimeter and the external device is via Bluetooth.
- Uses RAW_SENSOR data on capable phones (e.g. Nexus 5 and later) for most accurate color metering
- Option for calibrating your camera by capturing a reference D65 white point
- Works with AMOLED and LCD screens
- Android 5.0 (Lollipop) or higher
- Bluetooth
- A good quality back-facing camera with DAYLIGHT (D65) white balance and manual exposure controls
Camera Colorimeter can also be used to perform a simpler auto color balance operation of Calibrated Photo Viewer, which has a lower set of requirements.
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.
The following describes the steps for using a device A running Camera Colorimeter to color calibrate another Android device B running Calibrated Photo Viewer.
Instructions for color calibrating a Windows device is given within the Display Calibration app itself.
Step 1. Turn on Bluetooth and pair the two devices.
2. Allow device B's screen to warm up by keeping it on for at least 20 mins.
3. Start Camera Colorimeter on device A, and Calibrated Photo Viewer on device B.
4. Determine the type of display on device B. If it has an AMOLED screen (for example, Samsung Galaxy S line of phones, Samsung Galaxy Tab S/S2, Nexus 6), then on device
A, select "Using AMOLED profile" from the menu, otherwise leave this option unchecked.
5. On device B, navigate to any photo and select "Calibration" from the menu. A sub-menu now opens. Select "Auto color balance" or " Auto calibration" from the sub-menu. A
dialog will pop up with a list of paired Bluetooth devices. Select device A from the list. The two devices should now connect.
6 (Optional). Select "Using linear tonemap" in the menu on device A. This option should be enabled if you are using a Nexus 6 running Android 6. On other camera devices,
including Nexus 6 running Android 5, this option should generally be left unchecked. If photos appear to have too much contrast however, then try calibrating again but
with this option enabled.
7 (Optional). Select "Using alternative raw capture" in the menu on device A. This option selects an alternative capture method and should be checked for Galaxy S6/S7 and
8. Place device A on top of device B, with the camera of device A on the circular region displayed on device B (See screenshot #3).
9. Click the "Calibrate" button on device A and wait for the calibration process to complete.
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.
Auto calibration takes about 20-30 mins so be sure that both devices have sufficient battery capacity to complete the operation.
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
