Three Key Technologies for Crystal Clear Images
Real-color Sensing
Real-color processing is an image processing technology that performs high-speed processing of full-color images with a total of 16.7
million colors (256 tones per RGB channel). This means that image processing can be performed with the same color information that is
visible to the human eye, and stable measurements can be performed under lighting that closely resembles natural light.
The camera image is processed as-is without any
loss of quality.
This enables even the slightest of color differences
to be captured with high accuracy.
Captured images are converted to a 256-shade mono-
chrome image and processed. This enables more stable
inspection compared to binary level processing, but
slight changes in color cannot be detected with this
method.
Captured images are converted to a black and white
two-color image and processed. This reduces the
amount of data and enables high-speed process-
ing.
HDR Sensing
High dynamic range minimizes the effects of lighting such as halation and allows highly precise inspections.
Lighting is required for stable image inspection, but shiny surfaces can reflect light, resulting in incorrect judgements. You can use
a polarizing filter to reduce specular reflection, but the entire image will be darker, which can result in insufficient image contrast.
The FQ2 Series is equipped with OMRON’s own high-power lighting DR optical system for effective use of LED power. This system
provides sufficient lighting for inspection even when the enclosed polarizing filter is used.
Overall image contrast is maintained,
and only reflections are eliminated.
Light is reflected.
The overall image is dark;
inspection becomes unstable.
