ABSTRACT OF THE DISCLOSURE A solid state color camera of a type in which a composite color video signal of the NTSC system is obtained without using a specific color encoder. The solid state color camera has a solid state image sensing device having a plurality of image sensing cells or elements aligned in both vertical and horizontal directions for converting a light information of an object into an electric signal information in association with said image sensing elements, a color filter disposed in a light path of said light information of the object for modifying said electric signal information inaccordance with color components included in said light information, a read-out register adapted to receive said electric signal information of one horizontal scanning period line by line from said solid state image sensing device and to supply an output video signal in a serial form, a separating circuit for separating a luminance signal component and chrorminance signal component out of said output video signal from said read out register means, an adding circuit for adding said separated luminance signal components and chrominance signal components, a circuit for deriving at a system output a composite color video signal acceptable in the NTSC color system, a supplying circuit for supplying vertical and horizontal scanning signals to said solid state image sensing device, a circuit for supplying read out pulses to said read out register, a frequency of said read out pulses being selected to ? x fS, where N and M are both integers and fS is a frequency of subcarrier of the NTSC color system. and an adjusting circuit for adjusting phase condi- tions of said luminance signal components at said system output as they become equal to said alignment states of said image sensing elements of said solid state image sensing device.
