CCD

CCD is the core component of the scanner. CCD is called a photoelectric coupling device. It can output different currents according to the intensity of the irradiated light to complete the photoelectric conversion process. The scanner generally uses a linear CCD. Each line of the linear CCD is generally composed of 3000 to 10000 light detection points, and there are three lines of R, G, and B. The more light detection points in a certain unit length, the higher the opti...

The so-called home projector, also known as a mini projector, TRT-3M portable projector, refers to a projector used at home, its roles are mainly used for home film, office, entertainment.

It can replace the LCD, which can play videos online, listen to songs, play games, e-books, picture browsing, etc. The mobile phone video is affected by physical performance, the screen cannot be bigger, and the scr...

The density range is a very important performance parameter for the scanner. The density range is also called pixel depth, which represents the range of bright light and dark tone that the scanner can distinguish. Generally, the density range of the roller scanner is greater than 3.5, while the density range of the plane scanner is generally between 2.4 and 3.5.

The scanner is a high-tech product integrating light, machine, and electricity. It is an important tool for input...

When we buy scanners, we often see this phenomenon. Many technical parameters, such as scanners with the same scanning format, optical resolution, and color bits, have very different prices, and some even tens of times. So, what are the differences between home scanners and professional scanners?

Lamps

Professional scanners will automatically detect the light intensity emitted by the lamp before scanning, especially when the scanner has just started becau...

Install USB scanner

The installation of this kind of scanner is very simple, users with almost no experience can quickly install the USB scanner in a short time. Regardless of the model or brand of the scanner, the specific installation method is almost the same. Generally, the following steps will be followed: (When installing the scanner, the installation steps of all brands are to install the scanner driver, the hardware conne...

The so-called home projector refers to the projector mainly used in the bedroom and living room. Its main function is digital imaging and movie display. With the improvement of people's living standards and the continuous increase of the housing area, the home projector is gradually favored by everyone and has a tendency to gradually replace traditional TV sets. And there is also the . However, different kinds of home projectors on the market are dazzling. How to choose and buy a home projec...

3. Install SCSI Scanner

SCSI scanner is also a typical scanner at present. The installation of this scanner is relatively more complicated than that of the previous two types of scanners. When installing a scanner using SCSI interface, everyone needs to open the chassis of the computer connected to the scanner and select an idle PCI slot, then insert the SCSI interface card attached to the scanner into the PCI slot, and then use screws to fix the SCSI card in the chassis o...

Scanners can convert written materials or physical objects such as pictures, photos, films, and manuscripts that want to be saved into pictures or PDF format, which can be scanned by pdf camera scanner, and input them into computers. They are important equipment for paperless work. So how to install the scanner? There are different types of scanners and different methods of ...

We often see “trapezoid correction” when we buy projectors, so what exactly does trapezoid correction mean?

What is trapezoidal correction?

Trapezoidal distortion occurs when the projector is not vertically aligned with the screen or when the projection screen has an inclined surface.

What is tr...

The main advantage of the projection display is to create large-size images which bring shocking visual effects. Image quality is one of the most important cores of projectors. With the progress of core technology and the development of production technology, the image quality of projectors has been continuously improved.

Core parameters determine the basis of image quality

The key parameters and unique technology are the decisive factors of projector ima...
