Patent ID: 7324138

Claim:
A false-color reducing device, comprising: a raw data reading processor that reads a raw data, in which a first row and a second row are arranged alternately in a vertical direction, said first row being formed by arranging a first pixel representing red (R) data and a second pixel representing green (G) data alternately in a horizontal direction, said second row being formed by arranging said second pixel and a third pixel representing blue (B) data alternately in the horizontal direction; a first interpolation processor that performs an interpolation on said raw data to generate R plane data in which all the pixels have said R data, G plane data in which all the pixels have said G data, and B plane data in which all the pixels have said B data; a color difference data calculation processor that calculates U data and V data, which are color difference data, regarding said first, second, and third pixels, using said R plane data, said G plane data, and said B plane data; a second interpolation processor that calculates a mean value of said V data of four pixels adjacent to said first pixel in oblique directions, and sets the mean value of said V data as replacement V data for said first pixel; and a third interpolation processor that calculates a mean value of said U data of four pixels adjacent to said third pixel in oblique directions, and sets the mean value of said U data as replacement U data for said third pixel.
