Fine Tuning of Birds-Eye View
 The fine adjustment function of camera calibration can check and adjust the difference between each camera.
 Fine adjustments can be performed for each camera. Move the
“+”-mark to select the camera by pressing the “CAMERA” switch.
 Perform the adjustment with the center dial and upper/lower/left/
right switches.
CAUTION:
Operate the center dial slowly because the changing of the
screen takes approximately 1 second.
NOTE:
 It can be initialized to the NISSAN factory shipment setting with “Initialize Camera Image Calibration” of “Calibrating Camera
Image”.
 The adjustment value is cancelled in this mode by performing “Initialize Camera Image Calibration”.
ZOOM function
 The ZOOM ratio of camera can be changed when calibrating the
camera.
 It shifts to ZOOM function mode by shifting the selector lever to a
position other than the “R” position → “R” position → other than “R”
position in the “Fine Tuning of Birds-Eye View” mode.
 The changing of ZOOM ratio can be performed for each camera.
Move the “+”-mark to select the camera by pressing “CAMERA”
switch and press the left/right s witch to change the ZOOM ratio.
NOTE:
 When the position is not correct in “Fine Tuning of Birds-Eye View”
mode, use this "ZOOM" function to adjust it.
 If this function is used, always adjust the upper/lower/left/right posi-
tion again on the “Fine Tuning of Birds-Eye View” screen.
