Features of Color Bit Code
Main Features
The code can be detected even if the capturing image is blurry.
1. Color Bit Code is readable even if captured image is distorted or blurry.
Camera does not have to be high quality because decoding requires very simplified combination of colors. Color Bit Code accepts wide color range and can be decoded in spite of color fading or various lighting conditions.
Color Bit Code can be a part of design or illustration.
2. Shape of Color Bit Code is free.
Because the decoder checks only the transition of colors, there is no limit on size and shape of each cell and the sequence direction. You can freely design Color Bit Code along limited available spaces.
3. Any material is possible.
Color Bit Code can be applied on any material even if it's flexible or stretch. Of course, Color Bit Code marking on glass, metal and fabric is easily decoded. Even ID management of tiny parts by Color Bit Code is possible.
Existing codes can not be applied on a lot of materials. (from left) rubber, tiny parts, fabric tag
Multiple codes can be decoded simultaneously.
4. Multiple codes can be decoded simultaneously.
Because position and order of multiple codes can be detected, you can easily find out the target object among many. Moreover, saving captured images with their information data ensures more accurate traceability.
| Technical Feature | Performance Advantage | Specific Advantage |
|---|---|---|
| Decoder checks only the transition of colors. | Detectable even if the captured image is blurry or distorted | Camera does not have to be high-performance. (Reasonable camera such as deep-focus one can be used.) |
| Decoding zone is wide. (Can be decoded from an angle.) | ||
| Detectable under various circumstances e.g.) moving object, optical obstacles such as liquid or plastic wrap | ||
| Detectable irrespective of its shape and size | Can be marked on any shape of objects or flexible materials e.g.) fabric, wire, irregular-shaped parts, rubber, edge of object | |
| Rough marking is possible. e.g.) stamp, spray, potting, chalk, beads, LED, marking on tiny area, marking on moving object | ||
| Can be a part of object design | ||
| Captured image is applied. | Multiple symbols can be detected simultaneously. | Position and order can be detected. |
| Target object can be found out. | ||
| Unreadable object can be detected. | ||
| Captured image can be saved. | ||
| It consists of 3 colors. | Acceptable color range is wide. | Rough marking or fading color is detectable. |
| Detectable under various lighting conditions | ||
| Can be a part of object design | ||
| Simple decode algorithm | Programming size is small. | High decoding speed |
| Can apply to various devices such as mobile phone. |
