9. Bad Mark Camera Test

Bad Mark Not Exist F16

As a result of the camera test and measurement for bad mark detection, the

gray value of the bad mark is indicated in the "Grad.

Val." cells and "Exist" or "Not Exist" in the "Judge" cells.

The mean value of the gray values for "Exist" and "Not Exist" (Bad Mark

Detection) is regarded as a threshold value for the bad mark detection.

Example :

Result of Measurement

85 in "Grad. Val." Cell for "Exist" in "Judge" Cell

199 in "Grad. Val." Cell for "Not Exist" in "Judge" Cell

85 + 199 = 284 ÷ 2 = 142 = Threshold Value
