A process of a pixel interpolation circuit is optimized for down-sizing of a circuit scale and improvement of process speed. The pixel interpolation method takes a pixel at a center of three rowxthree column image data as a target pixel subjecting interpolation process, and calculates color data of the target pixel and color data of pixels around the target pixel and adjacent thereto for outputting an interpolated color data for the target pixel. The pixel interpolation method includes a reading step of reading out image data of sequential first to third rows among image data of N rowsxM columns written in a memory, per each column, wherein N and M are integer greater than and equal to three, and a color data determining step of determining the interpolated color data for the target pixel on the basis of a first color data as one of color data for three pixels of the column read out immediately before color data of the target pixel, second and third color data for two other pixels simultaneously read out with the target pixel, and a fourth color data as one of color data for three pixels of the columnw read out immediately after color data of the target pixel data.
