Abstract
This research presents the design and development of a FriendlyARM-based color to frequency representation for media packaging color detection used in small media packaging industrial. The design was based on FriendlyARM Mini 2440 SBC (Single-Board Computer) with 400 MHz Samsung S3C2440 ARM9 processor and the color sensor used in this research was a programmable color light to frequency converter model TCS230 made by Texas Advanced Optoelectronic Solutions (TAOS) company. The frequency information gathered was used to create color to frequency representation. This research study in 4 filter modes: red, blue, green and non filter. Calibrate each CMYK color with standard color checker chart in difference mode. The results of study, the non filter mode can give the results better than red, blue and green mode. The output frequency span between color are 7.432 kHz, 3.5 kHz and 21.31 kHz for Black-Cyan, Cyan-Magenta and Magenta-Yellow frequency spans respectively compared to other filter modes. The advantage of this research are reduce the use of memory for storing the CMYK color data and can speed up the time of restoring and inspecting colors used in media packaging processes. ฉ (2013) Trans Tech Publications Switzerland.
