YIQThe original color space used for encoding NTSC video in 1953, which was very similar to YUV. Only a small number of TV sets that decoded YIQ were ever manufactured, and it became obsolete. All NTSC encoding today is YUV. See YUV. YIQ (communication) The method of representing colors in color television systems, where Y represents the luminosity, which is also the black-and-white signal, I represents red minus the luminosity, and Q represents blue minus the luminosity.

Specific tests conducted on the 750 MHz Blackfin Processor include: Compress and Decompress JPEG to simulate still picture image coding; High Pass Grey-Scale Filter to simulate front-end processing of digital still cameras; RGB to CYMK Conversion to simulate the performance of digital image processing in color printers and other digital imaging products; and RGB to YIQ Conversion to simulate digital video processing. Microprocessors from six manufacturers, in both out-of-the-box and fully optimized configurations, were compared for JPEG compression and decompression, gray space filtering, RGB to CMYK conversion and RGB to YIQ conversion. It allows users to convert among different color representations, including RGB space used by color monitors and scanners, CMYK space used for printing, YIQ space used for broadcast, the CIELAB space used as an international standard, and to 15 other color spaces, including dictionaries of color names, the Munsell color system, and the German DIN standard. |
