DigiEye, Non-Contact Digital Imaging System

DigiEye is a revolutionary non-contact digital imaging system that captures the total colour and appearance of 2D and 3D objects in a unique controlled lighting environment. A calibrated monitor gives true on-screen colour simulation of the object and the profiled printer produces high quality hard copies. DigiEye’s ability to select and retrieve colour data from any pixel in the high-resolution image allows the measurement of very small or irregular shaped samples. Measured colours are represented by their ‘finger-prints’ in terms of colorimetric values or spectral data. Electronic communication of the image and colour data is easy and fast over the World Wide Web using standard formats.

DigiEye is an invaluable tool for specifiers sourcing coloured components from different suppliers within a global supply chain. It provides an accurate, comprehensive specification for both colour and appearance against which suppliers can assess the quality of their production batches prior to dispatch. The synthetic colour constant spectral curves generated by DigiEye help to ensure that all product components match in all specified lighting conditions.

The DigiEye system is a complete colour imaging solution combining both hardware and software. The hardware consists of a characterised digital camera, a unique illumination cabinet, and calibrated high definition CRT monitor. The illumination cabinet has been designed by Verivide to provide even and consistent illumination which meets international standards. Independent tests show VeriVide’s D65 fluorescent simulators to be the best when compared to other commercially available light sources.

The basic DigiEye software consists of:

• Camera characterisation for transforming the camera’s RGB input to CIE
• Monitor characterisation for calibrating the CRT to display colour accurate images.
• Colour measurement provides colorimetric data and colour constant spectral reflectance values for selected areas of the image.
• Colour difference for comparing colour areas on screen using a choice of standard equations.
• Texture profiling and simulation builds an image database of representative textures, with the ability to recolour to any desired shade.
• Colour Clustering - An important requirement within the food industry is to calculate the percentage composition or coating of a product. Leading manufacturers within the biscuit, cereal and dairy dessert industries approached us to define this valuable feature.
• Colour Replacement - Designers and buyers require a product to be seen in different colours. With a global supply chain the recoloured products have to be electronically communicated rather than wait for the manufacture of the completed item.
