Trying to predict the future is always very esoteric, because without the power of the prophet, I will use the past as a flash into the bright future. In the imagination, let us measure 20,000 feet, and identify from there the changes that occurred at that time, and Trying to capture the moment before it appears.
About 40 years ago, drum scanners were born as the first generation of digital image input devices. Then, about 15 years ago, the first generation of flat-bed scanners appeared, which initially had no threat to drum scanners due to quality issues. However, about 6 to 7 years ago, they reached a satisfactory quality, they began to challenge the dominant position of the drum scanner at a lower price, and the simplicity and flexibility of use. Let the day have become a dominant platform scanner, dominate the wave of higher performance, lower prices part. However, as I said, a sudden newcomer called a digital camera is just like the drum scanner.
Observing other trends, we know that the sensor captures single pixels at a time, and the drum scanner captures one-line (or three-line) and flat-bed scanners at a time, and develops a pixel for a digital camera to capture one area at a time. Therefore, the trend is Can capture a lot of image information at the same time.
We also noticed that more pixels are not necessarily better, because many of the capacity in the disk is required to meet the smaller requirements, and the speed of the scanner is curbed by a competition! People do not want to wait for the machine, so the scanner gradually speeds up. Prices have fallen by 10 or more times and will continue to decline. In the end, apparently not at a minimum, they will be cheaper and easier to use, do not require years of trained mechanics, and only need temporary operators.
The source of these changes is the user's need to increase speed, reduce costs, ease of use, and smaller size—all of these requirements are achievable.
If the past was driven by new component technologies and user needs, then the same forces will drive the future. Let us further discuss the new technologies that are waiting for us to research around digital cameras, what we need in the future, and the realization of diversified projects.
The most important element of a series of future components of thinking is the sensor. They are included in the first two CCDs and CMOS. A faster, smart, three-line CCD with more components is predictable as a fast microprocessor. Therefore, they will continue to play a leading role in the near future. However, because of the increased sensitivity of CMOS, they will constitute a great shock. This has already happened with low-end scanners and digital cameras, and it has been politely continuing to attack from the bottom to the high end. Once their quality is good enough, they will dominate with other advantages. 16-megapixel CMOS surface sensors have been here soon they will appear in digital cameras and scanners.
Although not a miracle, lighting sources are changing. White light-emitting diodes, due to their improved stability, strength and efficiency, have greatly improved light-emitting performance. At the same time, a linear light source concentrator will allow existing fluorescent tubes to emit more light as needed. This will result in faster and more sensitive scanners.
Electronic devices that support higher levels of integration will contribute to lower cost and faster scanners. The "on-chip scanner" chip is already here, and faster data transfer to the host will enable the scanner to quickly obtain data.
New mechanical devices will appear or disappear due to the presence of face sensors, the sensors do not have to move completely, or they can move on a mosaic or laminated pattern and a so-called independent XY technology.
Colorimetry and IC C standards have been applied to the separation of matter, and it has been demonstrated that good color states are obtained. But it also produced some confusion. As it is widely adopted by 1/O equipment manufacturers and application vendors, the complexity is reduced and the entire color management process is hidden by the user, which means that it has been used. The seamless WSIWYG color will be the standard for the near future.
Also, good colors will be watched by the human eye, WSIWYG color is not enough. Allowing the user to specify his or her preferred tools emerges from fuzzy logic and can satisfy anyone? ?
There is also a space defined for intelligent software, with many megahertz processors, and a wealth of processing power to perform more complex algorithms so that the entire scanning process takes only a short time to process.
It will be understood that the larger area of ​​improvement is human-machine interface. It is solved through a combination of hardware and software. Now that the installation of the manuscript takes more time and is annoying, this is an urgent problem to be solved.
The pipe leading to the host will be widened to accommodate faster scanning speeds, and there are several situations for wired, wireless and light, dedicated or networked. If USB 2 is here, USB 3 will not be too far away.
Scanners are not a separate device, and while they are changing, as long as they are connected to a host, it can benefit from it. The host's greater computing power and storage capacity allow the scanner to relieve more processing tasks and direct it to the computer for processing. This has many advantages for users. The main idea of ​​cheaper scanners and multi-purpose scanners is to send simplified images to the host computer and store them in a complete state, then process the images as many times as required, and can be used for several screens, PhotoCD, printers. , Printing, Web...
We discuss the changes in components that will affect the design of future image input devices. But what kind of future equipment is to obtain images, and we must also discuss what users need.
The user was previously concerned with the quality of the image. Now he is satisfied with this. Maybe he expects higher? I believe that users are satisfied with the current work of a large number of professional scanners. With a dynamic range of approximately 3.8 and a resolution of up to 4O00 dpi, it is within the limits of most film originals because it is no longer sensitive to higher values. If you exceed this value, you will no longer be able to manufacture image scanners. Instead, you will manufacture scientific instruments.
On the other hand, higher speeds are always good. This is not only a productivity issue. We are faced with the same as people hate waiting for machines. Another way is OK. If I lose 10 words a minute, it is OK. , But when I press a key, it's annoying to delay a bit in the character display. What is the ideal speed flash speed. I said that the scans and images are displayed on the screen and have been color matched, including personalized color performance.
Competition will continue to promote price reductions and performance improvements. This is a trend that, like other electronic devices, will continue to foresee the future.
Scanner use is still more difficult for most users eager to use the scanner. The era of specialized scanner operators is over. It is expected that even occasional users will be able to scan well and they will be as easy to use as a copy so that the first scan can achieve acceptable results.
Some people like to use other sensitive components to copy them without connecting to the computer, but only through a dedicated line, they are connected or completely independent more like a device.
It is usually a scanner in a closed-loop environment. The scanner is designed for a special output device. Today or tomorrow, the final purpose of the scan does not have to be that the scan time is finally output to the printer, printer, Web, CD. In this way, multi-purpose capabilities will make the description more valuable and make life easier.
As mentioned earlier, the expected development of components and changing user requirements, various types of professional image capture devices: Today, there will be new devices, and how will it develop?
Drum scanners have not changed much, and people's needs are of the highest quality and high resolution. They are still around these, but they have a small bottleneck, and a small amount still maintains their high prices.
Platform scanners will still have great improvements over the next five years. They will have all the advantages of the aforementioned components, such as faster and more sensitive sensors, better light sources, and better and cheaper electronics. Their greatest advantages are speed, increased performance/price ratio, ease of use and reliability.
The use of face sensors will soon appear because the resolution of these components increases and the price drops.
The basis is that platform scanners will continue to dominate the image capture device and will be used by professionals for the next 5 to 10 years.
However, digital cameras are faintly visible on the horizon. They have been used for consumer and web publishing. Due to the appearance of high-resolution, high dynamic range and high sensitivity surface sensors, they have also begun to attract the attention of professionals, first in the studio and then in real life. 16 megapixel sensors are already here.
The key to being accepted by people is good quality and reasonable price. I believe that photographers can easily spend several times the price of traditional cameras, but get amazing savings and processing in consumption, and at the same time have the advantage of being able to immediately preview the images taken and eliminate the need for scanners.
Digital cameras do not simply pose a threat to printing scanners because they are a competitive image capture device. However, because they remove the input to the scanner film, unlike paper, film is not the media that people use to change information. It's just a storage device for analog images that film scanners can read. With long-term use, the use of film will decline, so high-end film scanners will be required.
It is important to emphasize this point: Unlike film, paper is longer (no matter if it is predicted that it must disappear). As long as it is, the reflection draft scanner will also exist because the need to convert one medium to another is always here. The retroreflective scanner will use face sensors in the future, which will make the scanner faster, easier to use and more reliable.
Is there a new type of image acquisition device in the process of development?
Because digital printing has become more popular, there is no clear line between it and ordinary printing. It will be made into what we call a hybrid scanner. A scanner that will be suitable for document scanning and image scanning. It is a scanner that has fast scanning speed and paper control capabilities, but also can handle high-quality, high-resolution color capabilities.
Increasingly rich network content has increased the demand for three-dimensional scanners. The editors of the E era wanted to provide real objects as much as possible and be interactive, providing more information to consumers who have a purchase intention.
The last kind of hybrid scanner is to let the user hold a scanner that is equivalent to a camera equipped with a mobile device - it can be used as a traditional scanner or a portable digital camera.
About 40 years ago, drum scanners were born as the first generation of digital image input devices. Then, about 15 years ago, the first generation of flat-bed scanners appeared, which initially had no threat to drum scanners due to quality issues. However, about 6 to 7 years ago, they reached a satisfactory quality, they began to challenge the dominant position of the drum scanner at a lower price, and the simplicity and flexibility of use.

A gas grill is a type of outdoor grill that uses propane or natural gas as a fuel source to cook food. It typically has a metal cooking grate, burners, and a hood or lid to trap heat and smoke. Gas grills are popular because they are easy to use and offer precise temperature control, making them ideal for grilling a variety of foods, from burgers and hot dogs to vegetables and seafood. They can also be used year-round, as they do not require charcoal or wood for fuel. Some gas grills also have additional features such as side burners, rotisserie attachments, and built-in thermometers.
