An image signal processing apparatus includes a line separation circuit. When interpolated image data is generated based on low resolution raw image data having color information distributed on a pixel of each line in the order of R, G, G, B, . . . , firstly, the line separation circuit converts a color distributing manner using two line memories. As a result of a conversion, the color information is distributed on the pixel of an odd number line in the order of R, G, R, G, . . . , and the color information is distributed on the pixel of an even number line in the order of G, B, G, B, . . . . Such a color separation toward the low resolution raw image data is performed using three line memories. On the other hand, when the interpolated image data is generated based on high resolution raw image data having the color information distributed on the pixel of the odd number line in the order of R, G, R, G, . . . , and the color information distributed on the pixel of the even number line in the order of G, B, G, B, . . . , the conversion of the color distribution is not performed, and the color separation is executed using all of the five line memories.
