Solid-state imaging device, color filter arrangement method therefor and image recording apparatus

A color filter arrangement method for a solid state imaging device having color pixels in which color filters are arranged for respective pixels, comprising:

• arranging two blocks of two pixels in a row direction×two pixels in a column direction of an X1 color on one diagonal line;
• and
• arranging a block of two pixels in the row direction×two pixels in the column direction of one of an X2 color and an X3 color and a block of two pixels of the other color and two pixels of an X4 color arranged diagonally on the other diagonal line, wherein
• magnitudes of wavelengths satisfy the following relationship:
• X3 color<X1 color<X4 color<X2 color.

An image recording apparatus comprising:

• a solid-state imaging device having color pixels in which color filters are arranged for respective pixels;
• and an image processing device, wherein
• in the solid-state imaging device:
• two blocks of two pixels in a row direction×two pixels in a column direction of an X1 color are arranged on one diagonal line,
• a block of two pixels in the row direction×two pixels in the column direction of one of an X2 color and an X3 color and a block of two pixels of the other color and two pixels of an X4 color arranged diagonally are arranged on the other diagonal line, and
• magnitudes of wavelengths satisfy the following relationship:
• X3 color<X1 color<X4 color<X2 color and
• the image processing device includes:
• a processing unit that adds four adjacent pixels of a same color of an image signal output from the solid-state imaging device.
