    ✒ Lens: Gathers light and projects the scene onto the surface of the imaging medium. Some are single lenses, and some require multi-layer glass lenses for better imaging effects.✒ Filter: The scenery seen by the human eye is in the visible light band, and the light band that the image sensor can discern is larger than the human eye. Therefore, a color filter is added to filter out the excess light band, so that the image sensor can capture what many people see. actual scenery.✒ Circuit board substrate (PCB board): transmits the electrical signal of the image sensor to the back end. For vehicle cameras, the circuit substrate here will have more circuits. It is necessary to convert the parallel camera signals into serial transmission, so that the anti-interference ability is stronger Some.✒ The basic working principle is that the target object collects light through the lens, and then filters out the unnecessary infrared light through an IR filter. Finally, the generated optical image is projected onto the image sensor. The optical signal is converted into an electrical signal, and after passing through the A/D (analog-to-digital conversion), it becomes a digital image signal, and is finally sent to a DSP (digital signal processing sensor) for processing. The DSP processes the signal into an image in a specific format and transmits it to the display screen for display.✒ Generally speaking, the lens group and CIS (CMOS Image Sensor) will be packaged into a module. After becoming the lens module, it will be packaged with DSP and other image signal processing chips to form a complete camera system.The above is basically the structure of the car camera. In addition, you need to pay attention to the placement outside the car body, because to take into account the occurrence of various harsh external weather and other conditions, you need to form a complete camera. If it is in the car The built-in camera, such as a DVR, does not need to be waterproof and can be assembled into a camera module.

    Why do images presented by a lens have optical aberrations?A. DistortionDistortion will cause real objects to be straight lines, but in photos to be non-straight lines, to be curved lines.a) barrelb) pincushionc) complex/wavyTypes of lenses prone to distortion: usually zoom lenses and wide-angle lenses.B. Field curvatureFor plane objects in reality, after imaging, the real image surface is curved, and most actual sensors are also flat, which will cause the center field of view and the edge field of view to be unable to present clear images at the same time.Lens types prone to field curvature: usually wide-angle lenses and large aperture lenses.C. Vignettinga) Vignetting-----Light FalloffUneven brightness Light Falloff, the exposure of the center field of view and the edge field of view are different, resulting in inconsistent brightness between the center and edge of the picture, which is what we often call the camera vignetting problem.b) Vignetting-----Color CastUsually there is a color difference between the edges of the picture (especially the corners) and the center area. It is not entirely caused by lens aberration, filters and sensors will also have a certain impact.Types of lenses prone to vignetting: usually largeThere are many factors that cause optical aberration in lenses, some of which have been shared above:1) distortion2) field curvature3) Vignetting ---Light Falloff4) Vignetting ---Color CastIn fact, there are some other influencing factors:1) Focus ShiftWhen you reduce the aperture size, the best focus plane will move to the front or back. That is, the aperture size will affect the best focus plane position, which is what we call focus shift.Common lenses that are prone to focus shift: large aperture lenses. When adjusting the aperture, the focus usually needs to be re-adjusted.2) Onion ring bokehThere are some out-of-focus circular rays of light in the optical path of the lens, which is generally caused by a defective lens.Common lenses that are prone to "onionrings": Some large aperture lenses often use aspherical lenses because of the flatness of the surface involved during processing.3) Flare-GhostingWhen there are some abnormal colored patches in the presented image, usually like colored circles or colored blocks of specific shapes, we become ghost images.Common ghost images: zoom lenses, lenses with a large number of lenses, and large-diameter lenses. During processing, try to reduce the aperture as much as possible, or use post-image processing.4) Flare-Internal ReflectionsGenerally speaking, highly reflective objects inside the lens, such as structural parts with too high reflectivity, or dirty lenses in the optical path, etc. In most cases it is caused by workmanship issues.Common internal reflection stray light lenses:especially large aperture lenses, during the production process, you can try to eliminate light, cut off light, block stray light, increase transmittance, and reduce the aperture as much as possible when conditions permit.
