A comparative study of the statistical properties of granulation in active and quiet regions is performed. The analysis is based on a high-resolution time series of simultaneous white light (lambda5425 Å) and G-band (lambda 4308 Å) images obtained at the Swedish Vacuum Solar Telescope, La Palma, Canary Islands. The G-band images have been used to
