Electronic image pickup apparatus and electronic image pickup method

An electronic image pickup apparatus, comprising:

• a color image pickup element which has a plurality of drive modes including at least a first drive mode and a second drive mode;
• an optical lens which converges light from a subject to the color image pickup element;
• a spectral sensitivity characteristics storage section which stores a first spectral sensitivity characteristics corresponding to the first drive mode of the color image pickup element;
• a spectral sensitivity characteristics computing section which computes a second spectral sensitivity characteristics corresponding to the second drive mode of the color image pickup element according to the first spectral sensitivity characteristics;
• a spectral sensitivity characteristics computation parameter storage section which stores the computation parameter for computing the second spectral sensitivity characteristics;
• a color-conversion parameter computing section which computes a first color-conversion parameter for converting a color data acquired by the color image pickup element in the first drive mode according to the first spectral sensitivity characteristics and also computing a second color-conversion parameter for converting a color data acquired by the color image pickup element in the second drive mode according to the second spectral sensitivity characteristics;
• a color-conversion computation parameter storage section which stores the computation parameter for computing the first and second color-conversion parameters;
• and
• a color-conversion section which color-converts the color data acquired by the color image pickup element in the first drive mode according to the first color-conversion parameter and also color-converts the color data acquired by the color image pickup element in the second mode according to the second color-conversion parameter,
• wherein the first color-conversion parameter is a first color matrix for use with the first drive mode, and the second color-conversion parameter is a second color matrix for use with the second drive mode.
