Image Guidelines

The Sybrin Identity SDK is not able to overcome the laws of physics and works exclusively within its capabilities.

For the Sybrin Identity SDK to work at its full potential it is imported to follow the image input guidelines as stated below. Each section contains good and bad examples to help visualize any issues you might experience regarding bad lighting, misalignment, reflections, etc.

Angle

The document should not be tilted or turned more than 10 degrees in any direction or orientation.

Correct	Incorrect - tilted	Incorrect - turned
​​​	​​​	​​​

Contrast

The document should be in clear contrast to the background. A light-colored document on a light background, as well as a dark-colored document on a dark background, might not be recognized.

Correct	Incorrect
​​	​

Distance

Ensure that the document does not take up too much or too little of the screen real-estate. A good ratio to aim for is to keep the document between 70% and 90% of the screen real-estate.

Correct	Incorrect - too close	Incorrect - too far
​​​	​​​	​​​

Focus

The document should be in focus and not blurred.

Correct	Incorrect
​​​	​​​

Lighting

Ensure the image has proper lighting conditions. Avoid over exposure, under exposure, too much or too little background or foreground lighting, glares, and reflections. Ensure that all the details on the document are visible.‌

Correct	Incorrect
​​​	​​​

Obstructions

Remove all obstructions, such as fingers covering the document. This can prevent the SDK from detecting all the necessary details.

Correct	Incorrect
​​​​	​​​​

Reflections

Avoid glares and reflections as they can interfere with the normal operations of the SDK. If possible, avoid using the flash as it can often cause reflections on the document.

Correct	Incorrect
​​	​

Resolution

The image resolution should be at least 1280x720. However, 1920x1080 is recommended.
