Figure2- 25: Moving diagonal gray gradient test image
 SlantLine
In the static diagonal gray gradient test image, the first pixel gray value is 0, the first pixel gray value of
adjacent row increases by 1, until the last row. When the pixel gray value increases to 255, the next pixel
gray value returns to 0. The first pixel gray value of adjacent column increases by 1, until the last column.
When the pixel gray value increases to 255, the next pixel gray value returns to 0.
Compared to the moving diagonal gray gradient test image, in the adjacent image of the static diagonal
gray gradient test image, the gray value in the same position remains unchanged. A printscreen of the static
diagonal gray gradient test image is shown in Figure2- 26.
