1. National Instruments Corporation 1 IMAQ PCI 1405 User Manual Appendix B Introduction to Color The perception of a color depends on many factors such as the following e Hue which is the perceived dominant color Hue depends directly on the wavelength of a color e Saturation which is dependent on the amount of white light present in a color Pastels typically have a low saturation while very rich colors have a high saturation For example pink typically has a red hue but has a low saturation e Luminance which is the brightness information in the video picture The luminance signal amplitude varies in proportion to the brightness of the video signal and corresponds exactly to the monochrome picture e Intensity which is the brightness of a color and is usually expressed as light or dark For example orange and brown may have the same hue and saturation however orange has a greater intensity than brown Image Representations RGB Color Planes IMAQ PCI 1405 User Manual Color images can be represented in several different formats These formats can contain all color information from the image or they can consist of only one aspect of the color information such as hue or luminance The following image representations can be produced using the IMAQ 1405 The most common image representation is 32 bit RGB format In this representation the three 8 bit color planes red green and blue are packed into an arra2. area A rectangular portion of an acquisition window or frame that is controlled and defined by software brightness A constant that is added to the red green and blue components of a color pixel during the color decoding process buffer Temporary storage for acquired data bus A group of conductors that interconnect individual circuitry in a computer such as the PCI bus typically the expansion vehicle to which I O or other devices are connected CCIR Comite Consultatif International des Radiocommunications A committee that developed standards for video signals Also used to describe signals boards and cameras that adhere to the CCIR standards color space The mathematical representation for a color For example color can be described in terms of red green and blue hue saturation and luma or hue saturation and intensity National Instruments Corporation G 1 IMAQ PCI 1405 User Manual Glossary composite video contrast DAQ DMA driver dynamic range E external trigger field IMAQ PCI 1405 User Manual A type of color video transmission where synchronization luma and chroma information are transmitted on one analog signal A constant multiplication factor applied to the luma and chroma components of a color pixel in the color decoding process Data acquisition 1 Collecting and measuring electrical signals from sensors transducers and test probes or fixtures and inputting them to a co
