In the moving diagonal gray gradient test image, in the adjacent frame, the first pixel gray value of the next
frame increases by 1 compared to the previous frame. So, in the dynamic image, the image is scrolling to
the left. A printscreen of the moving diagonal gray gradient test image is shown in Figure 8-32:

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 Figure 8-33.

8.3.8. User Set Control
By setting various parameters of the camera, the camera can perform the best performance in different
environments. There are two ways to set parameters: one is to modify the parameters manually, and the
other is to load parameter set. In order to save the specific parameters of the users, avoiding to set the
parameters every time when you open the camera, the MARS-U3 series camera provides a function to
