Hitachi Vision System – Features
- HITACHI original adjustable matching method optimally suited for ink jet printers.
- Featuring a color camera for flexible print verification.
- Dedicated white LED strobe lighting and controller power supply *1.
- Optimally adjusted focus and lighting previously reliant on individual intuition.
- Print interpretation (Binarization) setup is easier, by suggesting the optimal color filter values.
- 1 For Models With Lights.
Hitachi Vision System – Reliable
Human-Like Assessment
- Matching Verification Method
HITACHI original adjustable matching method is adopted to enable human-like assessment according to changes in the size and line thickness of dot fonts. This allows the character size and tilt, which would otherwise be judged NG by general image verification, to pass the verification stage and prevents unnecessary item rejection.
- Corresponding to Color Camera
A color camera can be used to judge color differences that would not otherwise be identifiable by a monochrome camera. Software color filters eliminate the need for users to select lighting and install color filters.

Supporting The Setup Process
- Simplified Adjustment Guide
Simplified item setup by following the on-screen guidance.
Recommended value guide.
For general verification, parameters, such as “setting binarized level” and “setting color filter” , which may have a significant impact on verification preciseness, are displayed on screen for a user-friendly configuration, which would be conventionally difficult without professional knowledge.
Digital display of focus and diaphragm.
- Utilities
Optimally configured focus and diaphragm, which were previously reliant on operator’s experience and intuition, are displayed as numeric readings.
Various adjustments by checking the numeric data carry simple setting.
Assisted focal adjustment.
The point with the highest focal value of manual adjustment is found and displayed at the appropriate focal position on screen.
Setting of lighting and adjustment of diaphragm.
The densities (lighting) of the center and four corners are displayed when capturing the white image, which allows checking for uniform and appropriate lighting.
Hitachi Vision System – Versatile
Supporting precise print verification
- Various Corrective Functions Available
Even where the moving work rotates (±180°), the immediate rotation correction allows stable print verification.
Reference position correction
The print position of characters and logo marks can be set as reference values, which allows immediate catch-up for correction, even if the work position moves back and forth and around.
- Calendar and Count-up
The calendar and count function are built in for automatic catch-up with print data change such as the date of manufacture, best-before date, and serial lot number.
The offset function is provided for automatic calculations in compliance with the period (offset) setting.
Reinforced by combination
- Collaboration With Hitachi IJ Printers
High-level collaboration with Hitachi IJ printer. Switching items and changing printed characters on the printer side can be automatically aligned with the Vision System.
Storage of verification results and error patterns
- Traceability and Image Saved
The time and the verification results can be saved as traceability information.
