Briefly about the technical device
Self-reset camera app settings
You can fix this by checking its settings and setting the required ones. If the parameters are not saved after the upgrade. then install a third-party application or a previous working version of the standard camera application. You can find it on the forum w3bsit3-dns.com.
To summarize, we can say that the main reason for hazy images is involuntarily ripped off anti-reflective coating from the camera lens and contamination of the latter.
The problem is solved very simply. just wipe the lens with an alcohol solution.
Complaint about image quality from rear view camera, all-round camera
Complaints about the image quality from the rear view camera. Only valid for vehicles with a rear view camera (PR code KA2, 8A0, 8A3, 7X7, 7X8 or 7X9)
The image is too light / too dark / hazy.
Aid lines are fuzzy / grainy compared to similar vehicle.
Image streaks due to reflections in sunlight
The rear view camera creates a distorted image (fisheye) due to the wide-angle lens (approx. 140 °). This image must be converted to a rectangular image and corrected for display on the MMI display. As a result, the rear view camera image on the MMI display is less sharp in the corners than in the center.
Large MMI display helps to recognize this blurriness (similar to enlarging the image size).
2 and 3. The rear view camera dynamically reacts to ambient light and tries to find the optimal combination of brightness, contrast and color of the image for the given lighting conditions (comparable to the function of adjusting the exposure of a camera or camcorder). Therefore, the brightness, contrast and colors of the rear view camera image may differ from the actual.
In addition, the camera is not equipped with an infrared filter to increase sensitivity at night. This also leads to a violation of the color rendition.
Camera image on MMI display Real view
The brightness level can be adjusted in the MMI menu for the MMI display as a whole.
Contrast and color settings for the camera are hardcoded and cannot be changed.
For vehicles with a reversing camera (PR number KA2, 8A0, 8A3, 7X7, 7X8 or 7X9), there are several corresponding individual auxiliary lines for different steering wheel angles.
Continuously increasing the resolution and size of MMI displays aids in recognizing this blur / graininess of the auxiliary lines (corresponds to the increase in image size).

On vehicles with all-round vision systems (PR code KA4 or KA6), guide lines are dynamically generated like vector images and can therefore be displayed more sharply.

The streak in the rear view camera image is caused by light reflecting off the bumper in bright sunlight. The intensity of this phenomenon varies depending on the color and shape of the bumper, as well as the angle of incidence of sunlight.

Reversing camera coming soon to help cyclists record accidents
A US designer has invented a rearview camera that can be mounted on a bicycle seatpost and record footage in a continuous 10 second loop. potentially providing video evidence that can be invaluable in the event of a collision. When used in conjunction with a handlebar-mounted monitor, it also acts as a rearview mirror for the cyclist.
, dubbed Cerevellum Hindsight 30, was developed over the past two years by North Carolina-based Evan Solida through his 6ix Design company and includes an accelerometer, similar to the motion detection software inside the Apple iPhone, that controls the orientation of the screen. which, when detecting unusual movement, such as a collision, records the last ten seconds of video and then turns off.
According to the product website, “With the Hindsight 30, you can always tell what is coming from behind, whether it be a car or an enemy initiating a liftoff,” although we’re pretty sure the UCI might have a word or two to say on this second point.
The camera body, which can be attached to standard and aerodynamic seatposts, also includes a red LED rear light that can be set to always turn on, flash, or turn off.
The monitor unit also features a front LED indicator, which has a 3.5-inch transflective LCD screen that can be viewed in sunlight and is also backlit for viewing in poor visibility conditions.
Battery life is claimed to be 13 hours and the product will be shown at Eurobike this fall.
While the advantages of the camera in terms of potential incident recording are clear when it comes to use as a replacement for mirrors mounted on a bar or helmet, or just a good old-fashioned look over your shoulder, we wonder, however, whether the screen itself might just be a distraction. while you are on a bike
Solida has also integrated a camera into the frame of a concept bike he designed called the Rael, which also includes a patented shifting and braking system that actually sees the levers upside down, as shown on the Bicycledesign website.
Explaining the idea of changing the position of the levers, Solida says: “When you ride on conventional hoods, your index finger (the longest and most powerful finger) is next to the hinge of the lever. This is far from ideal. You can achieve maximum stopping power by rolling in drops with your index finger at the tip of the lever blade, the farthest point from the pivot axis.
“I flipped everything over so you have maximum modulation control when riding the hoods. In addition, the drops can be tilted outward at the user’s discretion. Another benefit is that the droplets are ergonomically shaped like a pistol grip, perfect for tough sprints. “.
Causes
They can be divided into 2 groups: hardware and software problems. The former include contamination of the camera lens, damage to the anti-reflective coating, lenses, matrix.
The second group of problems includes crashes after system updates, flashing, or accidental reset of the camera application settings.
The rear view camera shows dimly: what to do if it fogs up
Damaged lenses, matrix
Typically, these elements of the camera module are damaged by drops, moisture, or power surges.
Since this component is not repairable, you need to replace it yourself (the camera module in a smartphone is usually connected to the motherboard with a ribbon cable, and not soldered) or in a repair shop.
Is your backup camera dirty? Here is the fastest way to clean it.
The lens is dirty or the anti-reflective coating is damaged
These are the most common causes of blurry photos. Because of them, the light falls on the matrix distorted and therefore the image quality suffers.
If the lens gets dirty, just clean it with a cotton pad and car window cleaner or window cleaner.
To make sure that the anti-reflective coating is damaged, you need to inspect the lens in a well-lit place. when tilted in different directions, it should gleam in a dark blue or purple color. In this case, scratches should not be visible.
If they are, then you need to get rid of the remains of the coating by cleaning it off with a cotton pad dipped in 90% ethyl alcohol. The haze in the pictures will disappear.
