Abstract
A solid state color camera having a charge coupled device (CCD) on which the image of an object to be picked up is projected. In the color camera, the frequency of a clock signal, which is supplied to a horizontal shift register of the CCD chip for reading out a stored image signal therein, is so selected that the carrier frequency of a chroma signal, which is read out at the output terminal of the horizontal shift register, coincides with the color sub-carrier frequency (3.58 MH.sub.z) of a standard color television signal (for example, NTSC color television signal), and also the order for reading out image informations stored in image sensing elements of the CCD chip arranged in both the horizontal and vertical directions is so selected so that an output signal can be derived from the horizontal shift register with the same phase as that of the color sub-carrier of the standard color television signal.
