<p><P>PROBLEM TO BE SOLVED: To provide a technology capable of applying reduction interpolation processing with high accuracy to an image signal for expressing a color image with a plurality of pixels each including single color information. <P>SOLUTION: A circuit 5 for applying LV/RV reduction interpolation to an image signal of the RGB Bayer arrangement separates the input signal into four signal systems R, G, G, B, which are stored in a register 53. A horizontal direction counter 55H stores a count cntH to which a value LV is added every time a pixel is received. In the case that an odd order number of pixel (e.g., an R signal) is received and the count cntH reaches a value 2RV or over, a cntH-2RV is outputted as an interpolation rate h_RT and the interpolation is carried out by a ratio of h_RT: 2LV-h_RT. Further, in the case that an even order number of pixel (e.g., a G signal) is received and the count cntH reaches a value RV or over, a cntH-RV is outputted as an interpolation rate h_RT and the interpolation is carried out by a ratio of h_RT: 2LV-h_RT. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
