A solidstate digital television camera which has a solid state image sensing device, an A-D converter for converting the output of the image sensing device to a digital color signal, a filter for providing a predetermined filter characteristic to the digital color signal, and a digital color modulator for modulating the output of the above filter to produce a digital modulated signal. In the digital television camera, the processing rate between the solid state image sensing device and the filter is selected to have a sampling rate equal to that of the solid state image sensing device, or (n/m)pFsc where fsc is a color subcarrier frequency, p is 3 or 4, and m and n are relatively small integers. The processing rate for the remaining elements is selected to be pfsc. In addition, a D-D converter for converting the processing rate from (n/m)pFsc to pfsc is provided between the filter and the digital modulator. Thus, the digital television camera can be operated at a relatively slow sampling drive rate and can be constructed from integrated circuits.
