SIGNAL INTERPOLATING METHOD FOR SINGLE-CCD COLOR CAMERA

Japanese Patent JP3667464

B2

PROBLEM TO BE SOLVED: To obtain sufficient reduction effects on a false color signal by extracting a 1st integration signal generated by integrating a signal of a 1st pixel and a 1st coefficient signal and using the 1st integration signal as a signal corresponding to a 3rd fine color filter for the 1st pixel.
SOLUTION: The signal obtained by applying a coefficient signal obtained from a divider 13 and a B signal obtained from a solid-state element 1 to a multiplier becomes close to an R signal corresponding to the position where the B signal is obtained. When the R signal is obtained from the solid-state image pickup element 1, a low-frequency component of the R signal obtained from a low-pass filter 9 is applied to the divisor side of the divider 13 and a low-frequency component of the B signal obtained from the low-pass filter 10 is applied to the dividend side. Consequently, the signal obtained by applying the multiplier 15 with the coefficient signal obtained from the divider 13 and the R signal obtained from the solid-state image pickup element 1 becomes close to the B signal corresponding to the position where the R signal is obtained.
