Common flatbed scanners generally consist of a light source, an optical lens, a scanning module, an analog to digital conversion circuit, and a plastic housing. It uses the photoelectric element to convert the detected optical signal into an electrical signal, and then converts the electrical signal into a digital signal through an analog to digital converter for transmission to a computer for processing.

When scanning an image, the light source illuminates the image and the reflected light passes through the lens to converge onto the scanning module. The scanning module converts the optical signal into an analog digital signal (ie, the voltage, which is the intensity of the received light). Related), also pointed out the degree of darkness of that image. At this time, the analog-to-digital conversion circuit converts the analog voltage into a digital signal and transmits it to the computer.

The color is quantized by the 8, 10, and 12 bits of the RGB three colors, and the signal is processed into an image output of the above number of bits. If there is a higher number of quantization bits, it means that the image can have a richer level and depth, but the color range has exceeded the recognition ability of the human eye, so for us, the higher-order scanner for the range of resolution The effect of scanning is that the color is smooth and you can see more details.

Paper Straw

The raw material of the paper straw is white kraft paper, using two layers of 120g and one layer of 60g white kraft paper respectively. It is processed and produced with food-grade soybean-based oil ink and food-grade glue, which can be directly contacted with the human body and passed the FDA inspection.
