<[New Product] White / Infrared Image Scanner IRGB-6500 Features> Special software for scanning 1.2 billion pixels (A3-2400pi) in a single shot. * With conventional image scanners on the market, it was impossible to acquire 1.2 billion pixel images. An image of 1.2 billion pixels is equivalent to an image taken by arranging 40 8K cameras for 4K / 8K TV broadcasting, which have become popular in recent years. A3 size (310mm x 420mm) capture range is scanned at a batch with an optical resolution of 2400ppi. An optical resolution of 2400ppi corresponds to a resolution of 11 micrometers. It is resolution to divide hair (70μm) into 6 parts.
2. 4 roles per vehicle. Batch reflection and transmission of infrared and full color images.
¡By switching between two types of light sources, white LED array and infrared LED array, it is possible to scan multiple image modes at once with a single image scanner. (1) Full color reflection mode, (2) Infrared reflection mode, (3) Full color transmission mode, (4) Infrared transmission mode total, 4 types of images can be acquired at once.
3. Both sides of the white light source and infrared light source are difficult to cast shadows on solid objects.
When performing image analysis, the geometric arrangement of the illumination light is very important. For example, when comparing the direction of illumination light when comparing a full-color (visible) image and an infrared image, it is possible to determine whether the light is absorbed by infrared light or a “shadow” due to the geometric arrangement of the illumination light. It is very difficult to judge after scanning from the captured image. This problem is solved by a lighting device from all directions that is less likely to cause shadows.
Four. Effective capture dimensions are common in reflection / transmission mode. Share preview images.
In the commercially available image scanner (EPSON DS-G20000), the reflection screen and the transmission mode have a different capture range of 17 mm, so the preview screen cannot be shared. IRGB-6500 can share the capture range setting in all image modes.
Five. The scanner automatically corrects the focal position shift and magnification shift caused by the imaging lens of white light and infrared light.
¡Manufacturing lenses that satisfy the chromatic aberration of all 4 channels (IR / Red / Green / Blue) is very expensive. The IRGB-6500 automatically obtains an image by automatically focusing on the optimal focus position when acquiring full-color images and
near-infrared images. In general, at an optical resolution of 2400ppi (11μm), not only is the focal position shifted by the imaging lens, but also a change in image magnification becomes a problem. The difference is automatically memorized by the image scanner in advance. By doing so, the four channel images can be saved in layers using Photoshop, etc., and comparative analysis can be performed. Layer operation is performed on images of four channels (IR / Red / Green / Blue) of 1.2 billion pixels. This is a completely new image analysis method.
Furthermore, the focal position can be changed from 0.0mm to + 6.0mm according to the height (floating) of the sample placed on the platen glass surface.

(1) Invisible ink / visible ink print quality inspection
(2) For functional film defect analysis
(3) Creating an image database of buried cultural property relics (4) Visualization of old documents and old photos that have disappeared (5) For authenticity analysis of forged documents and counterfeits
■ Wood simple
Infrared rays are absorbed by the carbon component of the ink brush soaked in the wood fiber (cellulose), making it easier to visualize and interpret the characters.

■ Yes
It seems that the apparent stains of the rank are caused by smoked scents when praying. For this reason, in the near-infrared image, the stain component is transmitted, and the characters of the ink brush (carbon) written on the wall easily emerge. Surprisingly, the characters are easy to read.

■ Pattern (katagami)
Patterns represented by Ise Katagami have been carefully preserved as patterns in the Edo period kimono. The direction of three handmade Japanese papers is changed to a right angle and carefully piled up, and it is devised so that the direction of expansion and contraction becomes isotropic when wet. In addition, as a worm-eaten measure, the entire Japanese paper can be soaked in kakishibu. As a result, the color of Japanese paper is dark brown, and the ink seal is difficult to read with the naked eye. By comparing the infrared image and the visible image, we were able to unravel the history of manufacturing the pattern.

■ Dropout color (RGB)
The color reproduction mechanism of ink used in industrial
applications is called subtractive color mixing, and it consists of three colors of ink: cyan, magenta, and yellow. Each absorbs red, green, and blue light. However, all these inks are transparent because they are “transparent” at wavelengths in the near-infrared region. On the other hand, carbon does not change its absorption characteristics even in the near infrared image area. As a result, even if the sample looks different colors, the contrast remains only in the part with carbon in the infrared image and is visualized. Traditionally, for example, the function to erase characters written with a red pen on a document when scanning was called “dropout color (red)”. For infrared images, this “dropout color (RGB full color)” is also possible. [Image 5
