Abstract This procedure is aimed at solving the chromatic quantification problem in histological images, as well as other fields. On digital images, this is possible using colorimetric software applications. Our solution was to adopt a pre-processing step of the analog signal coming from a video-source (cabling a suitable, dedicated unit to the video-line before signal grabbing). The unit is a hardware device that processes the voltage values of the video signal image section, line by line in the raster image exploiting the vertical interval. The output is a luminance-free video signal compatible with real-time needs (1/25 second), that is in turn compatible with the normal exploration speed of a histological slide. Some experimental results are presented.

Our solution was to adopt a pre-processing step of the analog signal coming from a video-source (cabling a suitable, dedicated unit to the video-line before signal grabbing). The unit is a hardware device that processes the voltage values of the video signal image section, line by line in the raster image exploiting the vertical interval.
