As the first input device for image digitization, the scanner is developing rapidly, and new products and technologies are emerging one after another.
The optical resolution of the scanner has experienced 200dpi, 300dpi, 600dpi ... The development is quite fast. After 2000, due to the maturity of the CCD technology and the cost reduction, high performance and low price of 1200dpi optical resolution began to appear The scanner has made the scanner market quickly transition from 600dpi × 1200dpi to the mainstream scanner to reach 1200dpi × 2400dpi.
After 2003, a large number of high-performance scanners with an optical resolution of 1200dpi or 2400dp appeared on the market, such as Epson ’s Perfection 2400 Photo, BenQ ’s BenQ 5450, and Founder ’s F5600. , 48-bit color depth has become the standard configuration of scanner products on the market. Has been developed to 4800dpi high-resolution scanner. The rapid development of scanners is closely related to the continuous innovation of scanner technology. Mainly manifested in:
1. Technical innovation in image sensor applications
The continuous improvement of the resolution of the scanner has a direct relationship with the core component of the scanner-the image sensor. It is used for the acquisition and collection of scanned images, and its importance is self-evident. In order to improve the resolution of scanned images, many manufacturers have introduced many new technologies in the use of image photosensitive devices, and they have continued to mature in applications. Although the scanners currently produced are the same at 2400dpi or 4800dpi, the technologies used by different manufacturers may be different. There are:
(1) Varos technology
Varos technology is a new technology launched by Canon, and its design principle is developed on the basis of 600dpi. Through this technology, the ordinary 600dpi scanner is converted into a high-resolution scanner of l200dpi, which was first implemented on Canon's FB l200S scanner.
Because the optical resolution of the scanner is related to the number of pixels of the CCD. When an ordinary CCD scanner scans, the light irradiates the surface of the scanned object to form an elongated white light band. After being reflected by the mirror group, the light is focused on the CCD through a transmission mirror, so that the CCD receives Optical signal. In order to improve the optical resolution, Canon's Varos technology is to place a flat glass between the CCD and the transmission mirror, using the principle of optical refraction to double the resolution of the scanner.
Varos is very innovative as a new technology, but in recent years, there are not many scanners using this technology.
(2) Hyper CCD technology
Hyper CCD technology is a new technology adopted by Epson and was first implemented on the Perfect 1200S scanner. Through this technology, the ordinary 600dpi scanner is converted into a high-resolution scanner of l200dpi. The CCD used in the general color flatbed scanner is formed by three rows of linear sensors of RGB colors arranged in parallel. The Hyper CCD design is a 6-row CCD. This technology only needs one scan, and the scanning speed and registration issues are not affected. In the case of 1200dpi CCD prices are relatively high, using this technology is a better solution. It is also possible to use a 1200dpi CCD to produce a 2400dpi scanner.
(3) Linear array CCD design
In the linear array CCD design, the 1200dpi scanner uses a traditional linear array CCD, that is, RGB three colors are each composed of one line. In this design, the scanning speed is fast, and there is no color registration problem. For example, Microtek's ScanMaker X12USL uses a CCD of 10200 pixels, each pixel unit is 4μm, scanning A4 format <, optical resolution is 1200dpi. It is the same size as the CCD used in the 600dpi color scanner, because the CCD used in the 600dpi color scanner is 5100 pixels, and the pixel size is generally 8μm. Because the former pixel size is halved, the number of pixels is doubled. , Is a 1200dpi scanner in the true sense. Founder 7200, launched by Peking University Founder in May 2003, is a scanner with a single CCD module and an optical scanning resolution of 1200dpi.
(4) Dual CCD technology
The dual CCD technology is the earliest new technology introduced by Hewlett-Packard and was implemented on the ScanJet 7400C scanner launched in 2001. The products launched by HP in recent years, such as the HP Scanjet 4070 launched at the end of 2003, use dual CCD scanning technology with an optical resolution of 2400dpi.
This technology only needs one scan, and the scanning speed and registration issues are not affected. In the case of 1200dpi CCD prices are relatively high, using this technology is a better solution.
(5) LIDE technology
LIDE technology is Canon's new technology, LIDE (LED Indirect Exposure) is the abbreviation of diode indirect exposure technology. It is a technology that uses a group of high-brightness three-color light-emitting diodes and a contact image sensor (CIS—Contact Image Sersor). The biggest feature of this technology is the use of a separate light guide (Light Guide), in order to omit the series of mirrors required by traditional scanners, and the LIDE scanner also uses a cylindrical lens with a diameter of less than 1 mm. A large number of lenticular lenses are arranged in a row along the scanning line, so that the undistorted image can be restored every time. The final signal reception is realized by the newly developed linear image sensor.
In the home scanner market in 2003, Canon's LIDE series scanners were particularly eye-catching. In recent years, Canon's scanners have basically adopted LIDE technology, such as CanoScan LIDE 60, CanoScan LIDE 35, CanoScan LIDE 30, etc.
2. Direct light path image technology
Direct optical path imaging technology (EDIT——Emulsion Direct Imaging Technology) is a patented technology of Microtek, which was first implemented on the Microtek Scanmaker 5 scanner, and later launched the ArtixScan series of scanners, that is, patents with dual light sources and dual platforms technology. Now the Microtek ArtixScan 1010Plus and 2020 scanners, which are widely used in the prepress field, use this technology. The main performance is:
(1) Dual light source system
Its optical path system is uniquely designed, with two cold cathode lamps used for the reflective light source and one cold cathode lamp used for the transmitted light source. The reflected light path and the transmitted light path are organically combined through four fixed mirrors, a rotating mirror and a transmission mirror.
(2) Dual platform technology
The double platform refers to two separate scanning platforms-the reflective manuscript is placed on the glass plate of the scanner; the transmissive manuscript is placed on a removable tray like a drawer under the glass plate. Each platform has a different light source and optical system, so that the scanning optical path of both types of originals is optimized. Due to the ingenious design of the optical path, the mechanical structure is compact, and the appearance is no different from the traditional scanner.
With the dual-platform system for reflective drafts, the platform for transmissive drafts can be drawn out and loaded with film at any time, reducing waiting time, making batch scanning easier, and improving production efficiency.
3. Dual lens technology
In order to meet the needs of high-precision scanning of manuscripts of different sizes, a dual lens group design is adopted. For example, Microtek's ArtixScan 2020 scanner uses a dual lens scanning module design and a rotating lens group patented technology to organically combine the transmission light path and the reflection light path. When scanning the A3 format and the optical resolution is 666dpi, the light valve blocks the lens of the 2000dpi transmission lens and selects the lens of the 666dpi transmission lens to work. When the scanning optical resolution is 2000dpi, the light valve blocks the lens of the 666dpi transmission lens, and the lens of the 2000dpi transmission lens is selected to work. In this way, the lens can be in a fixed ideal state from beginning to end, eliminating lens wear caused by movement, so that the system can achieve the best execution efficiency and accuracy, and make the scanned image quality better. Therefore, the dual-lens technology solves the problem of edge distortion caused by the scanning of a traditional zoom lens.
4. Dual scanning head technology
The HP Scanjet 4070 scanner introduced by Hewlett-Packard at the end of 2003, while using dual CCD technology, also uses dual scanning head technology. It will stagger the two scan heads to scan images of different resolutions. During the scanning process, the low-resolution part is processed by a fast, low-noise, low-accuracy scanning head, which is quite fast. The high-resolution part is served by another high-precision scanning head, and the advantages of the two scanning heads are comprehensively utilized to achieve the perfect unity of accuracy and speed. Thanks to this new technology, the HP scanner completes the scanning of an A4 image in 4 seconds.
5. XY scanning technology
High-end professional-grade platform scanners that are widely used at present, such as EverSmart Supreme from Kodak (formerly Creo), Cezanne from NetScreen, Xinba series scanners from Heidelberg, and many from Polytron The newspaper scanners and Fuji C-550 scanners used XY scanning technology.
In March 2003, the original Creo exhibited the iQsmart 2 scanner, Zhijia 3 scanner, EverSmart Supreme Yongjia extreme color scanner at the PMA 2003 show in Las Vegas, and printed it in China in 2004 Application in the field. XY Stitch seamless scanning technology can divide the entire A3 format into 4 scanning areas. If each scanning area is scanned with a 8000 pixel CCD, the entire A3 format can be scanned with a 32,000 pixel CCD, making any size original Both can provide high resolution and high definition in the entire scanning range.
6. The scanning speed keeps increasing
In order to improve the scanning speed, the interface mode of the scanner has changed a lot. After 2003, the newly launched scanners have adopted USB 2.0 and / or IEEE 1394 interfaces. The transfer rate of the USB 2.0 interface has reached 480Mbps, which is 40 times faster than the 12Mbps of USB 1.1. At present, IEEE 1394a is mostly used, and its transmission rate is 400Mbps. If IEEE 1394b is used, the data transmission speed is increased to 800Mbps, which provides a guarantee for the improvement of the scanning speed.
