We present 619 measurements of 606 visual double stars made by CCD imaging from 1996 to 1999 with the 74 cm and 50 cm refractors of the Nice observatory. Angular separation, position angle and magnitude difference are given. Magnitude differences estimated from CCD images are compared with magnitude differences given in the Hipparcos catalog. The residuals in angular separation and position angle are computed for binaries with known orbit. Table 2 is only available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/378/954
