PROBLEM TO BE SOLVED: To provide a multi-lens and multi-CCD type image pickup device capable of realizing improvement of the performance of the whole image pickup device and a reduction in the cost. SOLUTION: The multi-lens and multi-CCD type image pickup device is provided with image pickup elements 4, 5, 6 for R, G, B each having a light- receiving surface of the same size and processing circuits 7, 8, 9 therefor. The number of pixels of the image pickup element 6 for B is reduced compared to the number of pixels of image pickup elements 4, 5 for R, G. Conventionally, a gain of a processing circuit of a B channel is much larger than that of a G channel, and this causes the deterioration in the S/N(signal to noise) ratio of a chroma signal. However, in the above-mentioned constitution, since the sensitivity of the image pickup element for B is larger than those of image pickup elements of R and G, the gain of the processing circuit of B can be made to be small, thereby improving the S/N ratio of the chroma signal.
