<p><P>PROBLEM TO BE SOLVED: To correct image data on a small circuit scale without causing deterioration in processing performance and an increase in cost. <P>SOLUTION: A format conversion circuit 309 converts first image data composed of a Bayer array of R, G1, G2, and B color components into second image data composed of the R and B color components and a luminance component. Low-pass filter circuits 304 and 305 separate the second image data into each frequency band. A frequency decomposition circuit 301 outputs the second image data separated into each frequency band. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
