Bayer data is captured by a CCD and is store in a memory. Image data is read out from the memory in units of nine lines starting with (4n+1)-th (n: integer) line. YUV data of one pixel is formed based on 5.times.5 pixels in the read Bayer data. Thus, the YUV data is formed in units of five lines. The YUV data is enlarged by a pixel number converting unit.
A solid state imaging device of the present invention comprises a solid state imaging element which includes a plurality of photoelectric conversion elements arranged in a matrix. In the solid state imaging device of the present invention, a pixel mixture unit area includes q pixels (q is a natural number equal to or greater than 2) in the first direction of the solid state imaging element and p pixels (p is a natural number equal to or greater than 2) in the second direction that crosses the first direction. The solid state imaging device includes: means for performing a first-field pixel addition process of adding together electric charges of a plurality of pixels included in the plurality of pixel mixture unit areas and a second-field pixel addition process of adding together the electric charges of the plurality of pixels included in the plurality of pixel mixture unit areas based on a combination of the pixel mixture unit areas which is different from that of the first-field pixel addition process; and means for alternately outputting signals of the electric charges obtained in the first-field pixel addition process and second-field pixel addition process as signals for interlaced scanning.
