Digital camera

A digital camera comprising a solid-state image pickup element, the solid-state image pickup element comprising:

• first color pixels which detect an amount of incident light of a first color of three primary colors;
• second color pixels which detect an amount of incident light of a second color of the three primary colors;
• third color pixels which detect an amount of incident light of a third color of the three primary colors;
• and
• luminance detection pixels which detect luminance information, each of the luminance detection pixels being adjacent to each color pixel of the first, second and third color pixels,
• wherein the digital camera comprises:
• controlling means for, when data of a reduced image in which a resolution is more reduced than a resolution of all pixels of the solid-state image pickup element are to be produced, adding data of each color pixel in a set of color pixels to be selected among the first, second and third color pixels, and data of one or more of the luminance detection pixels which are adjacent to said each color pixel in the set of color pixels to be selected;
• and
• signal processing means for processing data of the set of color pixels to be selected to which data of luminance detection pixels have been added, and reproducing a photographed image.

An imaging device comprising:

• a solid-state image pickup element comprising:
• a plurality of color pixels, in which each pixel of a plurality of color pixels detects an amount of incident light of a single color, wherein a plurality of different colors are detected;
• and
• a plurality of luminance detection pixels which detect luminance information, each of the luminance detection pixels being adjacent to a pixel of said plurality of color pixels;
• a controlling section that, when data of an image in which a resolution less than a resolution of all pixels of the solid-state image pickup element are to be produced, adds data of each of a set of color pixels to be selected among said plurality of color pixels, and data of one or more of the luminance detection pixels which are adjacent to said each color pixel in the color pixels of the set of color pixels to be selected;
• and
• a signal processing section that processes data of the set of color pixels to be selected to which data of luminance detection pixels have been added, and reproduces an image.
