A color solid-state image-pickup camera system is provided with a color solid-state image-pickup unit for acquiring image information by picking up an image of a subject, a vector quantization section, a first code-book storage section that stores code-book vectors for compressing image information, a vector decoding section and a second storage section that stores a plurality of kinds of code-book vectors for decompressing the image information. The vector quantization section outputs information for identifying code-book vectors that correspond to the respective blocks of the image information that has been acquired to the vector decoding section. Based upon the information, the vector decoding section selects code-book vectors that represent the luminance signal and color-difference signals, and reconstructs the respective blocks. Therefore, it is possible to carry out a color-separation process on image information by merely conducting decompression by the vector quantization method in the vector decoding section, and consequently to eliminate the necessity of providing a specific circuit for a color-separation process. This makes it possible to minimize the circuit scale and reduce the manufacturing costs.
