Galaxy A9: What is Flaw detection accuracy?

Last Update date : Oct 29. 2020


Accuracy of Flaw Detection may differ depending on surrounding conditions or subject. Blink and blur detection works best when there are three or fewer people in the frame, 1.5 meters or closer to the camera. Lens smudge and backlight detection may only work once in a 24-hour span.


Please refer to below operation algorithm used for Flaw detection.


1 Eye Blink


•    Measures the eye size in preview


•    Detects any change in the eye size when the shutter clicks, and checks whether the eyes blinked.

2 Photo Blur


•    Detects blur caused from the photographer's shaky hands by using the sensor in the device.


•    Detects face blur by recognizing the subject's face movement.

3 Lens Smudge


•   Gives a notice only once during the first 10 seconds of opening the Camera app to prevent its usability from decreasing.

4 Back Light


•    Detects backlight by distinguishing saturated areas in the image data input into the sensor.


•    Recommends the user to use "HDR auto" when HDR is off.
