warning glare

The reason for the glare of the camera was that the light reflected and spread inside the lens. The lens was composed of a series of concave and concave lenses. When light passed through a single lens, part of the light was reflected back. After the reflected light was reflected back and forth between the lens groups, a part of it would eventually pass through the lens to reach the sensor to form a light spot, which caused glare. Relatively speaking, a lens with fewer lens sets had fewer reflective surfaces, and anti-glare was relatively easy to do. A lens with a larger zoom would have a worse glare performance due to the large number of lenses, even if the anti-glare technology was the same. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The lens dispersion was caused by the lens not focusing light of different frequencies into the same focal plane, or the degree of amplification of light of different frequencies was different. It could be divided into "vertical aberrations" and "horizontal aberrations." The lens showed that the degree of dispersion of the glass would lead to different degrees of color aberrations. Because the camera lens used white light to form an image, and white light was composed of different wave-length visible light. Different wave-length visible light passed through the glass at different speeds and had different refraction index. After the light passed through the lens, it was similar to a prismatic mirror effect. Different wave-length light could not be focused at the same focal point, forming dispersion (purple edge phenomenon) on the image. In theory, it could happen in the center and edge of the image, but the optical path at the edge was long, and the dispersion was more obvious. The short wave-length had high refraction index, and purple was sensitive to color difference. The purple edge usually spread from the inside to the outside, and the optical path of the telephoto lens was long, so the dispersion phenomenon was easy to see. The lens glare was caused by the light spreading and reflecting inside the lens. The camera lens was composed of many individual lens units. When the light passed through, most of it passed through directly, and some of it was reflected back by the lens surface. This internal reflection of light reached the sensor and formed a lens glare. It was manifested by the appearance of light spots and fog in the photo, which would reduce the contrast and saturation of the photo. The glare of a zoom lens was more serious than that of a fixed-focus lens because it had more lens units, so the light spread and reflected more. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Glare and dispersion are two different phenomena in lens optical aberrations. The lens glare was caused by the light spreading and reflecting inside the lens. The camera lens was composed of multiple individual lens units. When light passed through these lenses, most of it would pass through directly, and some of the light would be reflected back by the lens surface. A portion of the reflected light inside the lens would eventually reach the sensor, forming a light spot, which was the lens glare. Glare would cause light spots and fog to appear in the photo, which would reduce the contrast and saturation of the photo. Dispersion refers to the phenomenon that light of different colors (different frequencies) cannot be focused on the same point after passing through a lens. This was because different colors of light had different degrees of refraction in the lens, resulting in differences in their positions on the image plane. In terms of imaging, it might appear as colored edges at the edges of the image, affecting the clarity and color reproduction of the image. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If you want to install an automatic anti-glare rearview mirror, the steps are as follows: First, dismantle the interior rearview mirror of the original car and observe the base of the ordinary rearview mirror of the original car. It was usually fixed by a buckle. Carefully pry open the buckle to remove the interior rearview mirror. Next, he installed the new automatic anti-glare rearview mirror. As it was a suitable modification component, he inserted the new interior rearview mirror into the rearview mirror base and then plugged in the rearview mirror's circuit. During construction, it is recommended to move the line of the automatic anti-glare rearview mirror from the middle of the ceiling to the left A-pillar position, and then down to the fuse box in the car from the A-pillar position. During the process, the line should be wrapped and fixed to avoid abnormal sounds in the later stage. Finally, the fuse box could be used to take power. You could buy a fuse collector and directly take power from the ADC fuse or the cigarette lighter fuse in the fuse box in the car. This way, the automatic anti-glare rearview mirror could work after the entire car was powered up. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The anti-glare function of the rearview mirror referred to the ability of the rearview mirror to absorb or reduce the reflection of the strong light when the light from the rear car shone on the rearview mirror during driving. This prevented the reflected strong light from shining on the driver's eyes, thus preventing the dazzling phenomenon from affecting the driver's attention. The automatic anti-glare rearview mirror works as follows: - A layer of electrochromic material was added to the mirror surface of the rearview mirror, which was automatically darkened by the light sensor to achieve anti-glare. This automatic anti-glare rearview mirror system usually had two sensor components, one in front of the rearview mirror to sense the brightness of the surrounding light in front of it, and the other facing back to sense the brightness of the taillights. According to the difference between the front and back light intensity, whether to turn on the anti-dazzle function is judged. When the front light intensity is greater than the back light intensity, the anti-dazzle function is not turned on, and the color of the mirror surface remains normal; when the front light intensity is less than the back light intensity, the anti-dazzle function is turned on, so that the color of the mirror surface darkens. Some of the high-end anti-glare rearview mirrors in the car would automatically disable the anti-glare function when the car was in reverse gear. - The main components of the automatic anti-glare rearview mirror included two light detectors, a color-changing mirror, and an electronic controller. The electronic controller changes the output voltage according to the difference in the intensity of the light absorbed by the two photodetectors. When the light at the back is stronger than the light at the front, the output voltage of the electronic controller increases, causing the color of the liquid to darken. The mirror displays dark light, reducing the intensity of the light at the back, and playing the role of anti-dazzle. This rearview mirror could automatically switch the anti-glare function according to the light intensity behind it without the driver's manual operation. At the same time, it could also automatically turn off the anti-glare function according to the actual situation (such as automatically turning off after the reverse gear), or it could be turned off manually by the driver. There was also a manual anti-glare rearview mirror, which had two mirrors with different reflections and was installed at different angles. The driver could adjust the direction of the reflected light of the two mirrors by turning the lever, so that the driver could "call" the two mirrors with different reflections to work. During the day, the high-reflective mirror was used to ensure that the rear image could be clearly reflected. When it was illuminated by the strong light from the rear, the low-reflective mirror was used through the lever (to the rear of the car) to weaken the light intensity and avoid affecting the driver's line of sight. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
