White balance of scanner
When performing the white balance of the scanner, the first thing to do was to clean the scanning glass inside the scanner main body, the tabletop of the scanner main body (the manuscript delivery tabletop), and confirm that there was no dust or garbage on the paper used for the white balance. It will take some time to perform the calibration. During this time, do not turn off the scanner's power, or there may be a problem that requires after-sales service personnel to solve. The paper used for the measurement should be properly kept to prevent it from being damaged, distorted or dirty. The measurement paper is a paper product and cannot be cleaned with liquid. The specific steps were as follows: 1. Start (scanner adjustment), display (scanner) menu, select (white balance adjustment). 2. After the relevant screen was displayed, he chose (All) and clicked (Execute). 3. Follow the instructions and insert the paper into the scanner. 4. Press (OK) to start the calibration.10 minutes later, the calibration. Press (OK) to end the calibration.1 5. To confirm the result of the adjustment, you can click (Confirm) on the (White Balance Alignment) in the (scanner) menu and insert the adjustment paper into the scanner again according to the prompt. 6. The scanner began to scan after clicking (OK). After the scan, check the read data to confirm that there are no vertical stripes such as white stripes. If there are no abnormalities in the data, the adjustment operation will end. Then, click (Close) to exit (the scanner adjustment program). If there are abnormalities in the data, select the specified part from the (white balance adjustment) menu, move the mouse to the cross on the data, and point to the striped part to specify.

White balance Detection Tools
The following are some white balance Detection Tools: - In PS, you could enter the Camera Raw through the filter " Camera Raw " filter. The white balance tool in the basic panel could be used to correct the color bias of the photo. The white balance tool was a slanted straw icon that could absorb the reference object in the picture. The ACR would automatically determine and adjust the white balance parameters. - The gray card in the Anwenk Gray Card Set was a basic white balancing tool. The set also included pure white and real black cards. - VidPro WD- 24 white balance disc, with an 18% gray exposure target on one side and a white surface on the back. It was foldable and could be placed in a suitcase when not in use. - ExpoDisc 2.0 white balance filter was the industry standard for white balance filter. It could capture the incoming light reading and set a custom white balance accordingly. It was available in 77mm and 82mm thread size. - Some cameras had a white balance evaluation function, such as a LCD camera, which could detect the appropriate white balance setting by placing your finger in the center of the screen and constantly changing the camera's white balance according to the environment. - In the premiere, if there was a white object in the photo, you could use the " straw " tool behind the white balance to click on the white object for automatic white balance correction. You could also manually adjust the color temperature and color, but you needed color knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White balance algorithm classification
White balance algorithms were commonly categorized into Gray World Assimilation, Perfect Reflection Assimilation, and dynamic threshold method. Among them, the average, perfect reflection, gray world, color correction, dynamic threshold, and so on can also be used as different white balance algorithm strategy modes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Color white balance algorithm
The white balance algorithm was to find the neutral color points of different brightness in the image (these points should theoretically satisfy R = G = B, but they may not be equal due to color cast), and then map them into equal values to obtain the action matrix of balanced color, and then carry out color balance processing on the whole image. Calculating the brightness of the original image with color deviation, the point close to the maximum brightness value is defined as a white point, calculating the average value of the R, G, and B color components and the brightness average value of all the white point set, and then calculating the adjustment parameters of color balancing according to a specific formula. Finally, the color balance adjustment is carried out on the R, G, and B color components of the entire image. There was also a multi-mode white balance algorithm that was based on the traditional white balance algorithm in the field of cameras. It added an AI white balance algorithm and an auxiliary color temperature sensor to integrate a variety of information to achieve a better white balance effect. This algorithm could accurately identify the true color temperature of the current light in the green or blue screen background scene, thus perfectly restoring the true color of the host and the product. It could achieve the true and natural color restoration of objects in all color temperature environments, and the skin color effect of people was excellent. Increases the authenticity and stability of the white balance, the ability to express colors, and the ability to restore the atmosphere. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White balance inconsistent with the environment
White balance was a setting used to ensure that white objects appeared white during shooting. Under normal circumstances, white balance should be adjusted according to the surrounding light to restore color. However, if the white balance setting was not consistent with the environment, it would produce a special effect. For example, if the white balance is set to a higher color temperature (such as a high color temperature value corresponding to more blue light) in an environment with a lower color temperature (red and yellow light), the overall image will be colder, which is inconsistent with the actual warm color environment. On the contrary, if the white balance is set to a lower color temperature in an environment with a high color temperature (blue light), the image will be warmer. This white balance setting that was inconsistent with the environment could be used in creative photography to create a unique atmosphere, express specific emotions, or achieve artistic visual effects by deliberately breaking the conventional white balance setting. In some scenes that needed to highlight subjective emotions or special visual effects, the photographer would adjust the white balance according to his own creative needs, so that it did not match the actual color temperature of the environment, rather than simply pursuing the accurate restoration of the color of the environment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
White balance adjustment of the surveillance camera
White balance refers to the restoration of white objects by the camera, which can correct the color difference between indoor and outdoor environments. For color cameras, white balance could be divided into manual and automatic. If the camera was found to have a serious color cast, it might be a problem with the white balance. White balance adjustment can be performed in the Fluorites Studio. The setting path is: (local area network) Fluorites Studio-Equipment Management-Advanced configuration-Front-end parameters-White balance. The white balance effect can be changed by adjusting the white balance gain. The greater the gain, the more obvious the effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
High-pass white balance algorithm
The white balance algorithm was mainly based on the grey world assumption, and most white balance algorithms were based on this assumption. The process of the algorithm was as follows: first, a reference point (reference lighting environment) was established, then the statistics of the color temperature were collected, and then the statistics were analyzed to identify the current color temperature. Finally, according to the identified color temperature environment, the corresponding RGH was supplemented to achieve white balance. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
scanner shutter
The largest external size of the scanner shutter product was 121.80mm x 88.86mm x 25.77mm. The average thickness of the plastic part was 2.70mm. The plastic part was made of PC+ABS. The shrinking rate was 1.005. The mass of the plastic part was 18.35g. The technical requirements of the plastic part were that there should be no defects such as peaking, incomplete injection molding, flow lines, pores, warping, silver lines, cold material, spray lines, bubbles, etc. The plastic part in the product drawing was a complex support. Although it did not have a complex surface, its height fluctuated greatly. Its shape was complex and its shape was symmetrical. It played a functional support role in the product and was a key component inside the product. There are four vertical walls in the middle, each with a through hole of? 3.2. The four holes here must ensure the requirements of the degree of concentration to facilitate the flexible rotation of other related parts after assembly. The two ends of the U-shape had a hook to assemble other components. There was a hook at the bottom of the U-shape. All these installation parts required accurate size, so there were high requirements for geometric tolerance. The difficulty of the mold design was the choice of the mold opening direction, the design of the parting surface, and the design of the four-hole sliding block core-pulling mechanism. Due to the large size of the plastic part, the complex structure, the fluctuation of the parting surface, and the many rubbing positions, the mold was ranked first. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR and scanner colors
There was a difference in color between an DSLR and a scanner. DSLR cameras worked based on the principle of color mixing of the two colors. The most common color modes were s-rmb and so on. This color mode was widely used in the digital field. The color effect of the scanner would be affected by many factors, such as the price of the scanner, the quality, the light source, the light-sensitive components, the glass, and so on. The color scanned would be different. However, there was currently no more information to show a more detailed comparison between the two colors, such as a direct comparison in terms of specific color reproduction and color depth. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
