Abstract: The colour space translation plays a significant task in pre-processing stage of digital image processing. Colour conversion can improve the quality of images. The objective is to convert one colour space to another and the inverse of same. Various colour space conversions are used such as RGB ← → HSV, RGB ← → HSL, RGB ← → HSI, RGB ← → YUV and RGB ← → YCbCr. The conversion process can be done using colour space conversion algorithm. The colour space conversion is used in various applications such as commercial, multimedia, computer vision, visual tracking systems etc. The hardware realisation of colour space conversion models can be implemented by using Xilinx system generator on field programmable gate array spartan-6. Finally, the above colour space conversion models are implemented in real-time then tabulated in terms of percentage resources utilisation and power required. The recommended RGB ← → HSV colour space conversion utilises 21% of DSP48A1s chips and required 0.354 watts of power. By means of colour conversion, the efficiency and speed are increased.
