Abstract
A method and device regenerating a pixel clock signal, the method comprising, and the device being configured for: determining a first drift value D1 representative of a first time difference between a reference clock signal RC and a local clock signal LC based on a local pixel clock signal LPC; adjusting the local pixel clock signal LPC according to an adjustment command to provide a regenerated pixel clock signal RPC; determining a second drift value D2 representative of a second time difference between the reference clock signal RC and a regenerated clock signal based on the regenerated pixel clock signal RPC; and providing the adjustment command to the adjustable clock generator 32; 132; 316 for adjusting the local pixel clock signal LPC, wherein the adjustment command is based on the difference between the determined first and second drift values.
