Abstract
Calculation is made about standard deviations of portions of high-frequency components GH, RH, and BH along respective predetermined directions. The portions of the high-frequency components GH, RH, and BH represent a prescribed number of pixels including an interpolation pixel located at a position corresponding to none of photosensor pixels in G, R, and B image sensors. The smallest one is detected among the calculated standard deviations. The predetermined direction relating to the detected smallest standard deviation is labeled as a highest-correlation direction in which the highest correlation occurs. Interpolation is implemented in response to portions of the high-frequency components GH, RH, and BH which correspond to the highest-correlation direction to generate a high-frequency interpolation-result signal RGBHI for the interpolation pixel and other pixels. Low-frequency components GL, RL, and BL are combined with the high-frequency interpolation-result signal RGBHI to generate high-definition green, red, and blue signals G(HD), R(HD), and B(HD).
