The temporal evolution of solar granulation has been investigated using a time series of high spatial and spectral resolution images acquired at the THEMIS solar telescope (Observatorio del Teide, Tenerife) using the IPM observing mode. In order to investigate different physical properties of solar granulation (associated horizontal velocity fields, lifetimes, intensity and geometry evolution), we identify and track solar granules automatically. We discuss the obtained results and compare them with results reported inthe literature. In order to overcome problems of atmospheric distortions, we also implement a FORTRAN95 code for the application of the Phase Diversity technique that is planned to be used at the THEMIS telescope.
