Human-like assessment
Matching verification method
Adjustable matching
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.
Providing flexible print verification
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.

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.
