Initial publication
The customer complains about the picture quality of rearview backup camera image in the MMI screen. The
complaints can be one or all of the following:
• The picture is fuzzy or distorted.
• The picture looks too bright, too dark, or opaque in certain areas of the image.
• The colors of the objects in the image are incorrect or slightly off.
• The guidelines used for parking are fuzzy, distorted, or pixelated when compared with the guidelines displayed
on another vehicle’s MMI.
Technical Background
Complaint 1: The picture is fuzzy or distorted.
Explanation: The wide angle backup camera lens provides a 140° curved, “fish-eye” image. The MMI software
straightens this image to fit the rectangular screen. As a result, the corners of the image look less sharp than the
center of the image (Figure 1). The condition is more noticeable on larger MMI screens because the image is
expanded.

Complaint 2: The picture looks too bright, too dark, or opaque in certain areas of the image.
AND
Complaint 3: The colors of the objects in the image are incorrect or slightly off.
Explanation: In order to display the optimal representation of brightness, contrast, and color, the backup camera
dynamically adjusts the image in the MMI screen in response to ambient light. As a result, the colors in the image
appear to be different than the actual colors (Figure 2). Colors in the image are also affected during nighttime
viewing because the camera is not equipped with an infrared filter.
The brightness of the image can be adjusted in the MMI menu (which will affect the whole screen for all MMI
menus), but color and contrast cannot be changed.

Complaint 4: The guidelines used for parking are fuzzy, distorted, or pixelated when compared with the
guidelines displayed on another vehicle’s MMI.
Explanation: In vehicles without the Peripheral View Camera (No Top View and No Corner View), the displayed
guidelines are static images that are overlaid on the camera image in the MMI at different steering angles. On
larger MMI screens, the lines appear pixelated because the image is expanded (Figure 3).
In vehicles with Peripheral View Camera (with Top View and Corner View), the lines are dynamically generated
vector graphics, which are scaled and appear sharper (Figure 3).
