Tests have shown that the MLC255 TC-true perception color sensor system can reach a maximum average color resolution of up to ∆E = 0.02 in the L*a*b* mode. Practically, the resolution in the L*a*b* mode is approximately ∆E < 1 and thus better than the human eye. This sensor system provides three main processing methods as described in the following sections. Color Sorting: The actual measured color value is compared with pre-sampled and stored color values. The best matching color is then the color classification result. A classification is always done without considering whether the color values really match or not. This method is widely used for automatic sorting of colored objects. Color recognition (Color checking) This method checks if the actual measured color is within one of the tolerance rooms of presampled and stored colors. The tolerance rooms are predefined by colorimetric ∆E units. If the measured color is outside the tolerance room, the color check is said to be unsuccessful (Color was not recognized). This method is widely used for quality checking of colored products and provides a fast and reliable quality inspection within predefined tolerance boundaries. Color sequence checking This method examines a proper sequence of colors. The color recognition and classification results are directly sent to the 8 open-collector outputs of the sensor system and can be coded as “1-out-of-N” (“One hot coding”), 7-segment or as a binary number. Thus either up to 8 colors, up to 20 colors or up to 256 colors can be represented. The parameter configuration of the sensor system, as well as the color sampling procedure (“Teach-in”); is carried out by PC software connected either by RS232 or USB to the sensor system. color variation vs. human perception color variation ∆E <1 1...2 2...3,5 3,5...5 >5 human perception very small color variation that can not be seen by the human eye small color variation that can be seen by trained human eye medium color variation that can be seen by average human eye considerable color variation high color variation page 3 INPROX sensors advanced color recognition system multi-function graphing platform 3 memory-output options ¤ 8 individual color memories utilizing open collectors (1-8 wires) ¤ 20 individual color recognitions using a 7-segment coding system ¤ 255 individual color memories using a binary output system 8 recognition-setup modes « « « « « « XY RGB (multiple reads) Raw R (contrast structural control) Raw G (contrast structural control) Raw B (contrast structural control) INT (intensity/gloss control) 6 color space systems « « « « « « XYZ xyZ L*a*b* L*u*v* u’v’L DIN99 specifications overview ¥ ¥ ¥ ¥ 10 kHz maximum response speed RS232/USB connection via TC-color scope software 12 bit A/D conversion Real-Time or EEPROM intellisense monitoring TC-color scope© software included page 4 INPROX sensors advanced color recognition system Electrical data Measuring value specification Light source Receiver Outputs Supply voltage Current consumption Interfaces Colour memory Signal amplification A/D conversion Switching frequency Colour resolution Relative accuracy at const. ambient conditions Colour spaces White light LED Brightness 3-range color photo diode Sensitivity OUT 0 to OUT 8 Interfaces Trigger output Data on ambient conditions Housing SB2 Pin 1 white 2 brown 3 green 4 yellow 5 grey 6 pink 7 blue 8 red Control input Operating temperature Ambient light comp.
