If monochrome sensors and methods<\/a> aren’t enough for your application, a machine vision color camera may be needed. And if color is needed, is “good enough” from a single sensor with a Bayer filter all you need? Or do you need the precision of a prism-based 3 sensor camera, one for each of R, G, and B? See our whitepaper Considerations for Color Machine Vision Cameras<\/a>.<\/p>\n\n\n

Prism-based 3-sensor imaging vs. interpolated Bayer mosaic sensors<\/figcaption><\/figure>\n<\/div>\n\n\n

Bryce Bayer, the engineer at Eastman Kodak whose name is associated with his Bayer filter<\/a> innovation, created a very compact and efficient way to layer a color filter atop a monochrome sensor. The vast majority of today’s color cameras – in both machine vision and consumer imaging – utilize precisely such a color filter mechanism to interpolate color. When the resolution is sufficiently fine, the rendered image is typically good enough for many applications.<\/p>\n\n\n\n

But “good enough” for some isn’t the same as good enough for all<\/h2>\n\n\n\n

Interpolation is a form of estimation – in the case of a Bayer filter its design presumes that the Red, Green, and Blue values between each of the “true” measurements of those values is the average of the values at the accurate points. So the in-between values are computed, and may or may not correlate to the true color present at the source.<\/p>\n\n\n\n

For certain machine vision, industrial imaging, and medical applications, maximum color accuracy is essential.<\/p>\n\n\n\n

Previously JAI’s Apex prism-based camera series<\/a> included 1.6 Mpix and 3.2 Mpix models. Three new models join the series, at 5.1 Megapixels each. The new members all use the same SONY IMX548, one of the Pregius S sensors<\/a>.<\/p>\n\n\n\n

If the new 5.1 Mpix models all use the same sensors, why are there three models? Because there are three interface options, depending on your need for speed.<\/p>\n\n\n\n
