Document Type and Number:
Japanese Patent JP6727911
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to create an interpolation signal that has suppressed a reduction in image quality at the position of an element for focus detection.SOLUTION: A high correlation pixel correction part (104) creates first correction signals to the positions of a plurality of elements for focus detection by using signals, of image signals of an imaging sensor having a plurality of elements for imaging and the plurality of elements for focus detection arranged on an imaging surface, in an image area having high correlation to signals of the elements for imaging adjacent to the elements for focus detection. A peripheral pixel interpolation part (105) creates second correction signals to the positions of the elements for focus detection by using signals of the elements for imaging on the periphery of the elements for focus detection. A mixing ratio calculation part (108) creates a mixing ratio on the basis of the chromatic aberration of magnification of the positions of the elements for focus detection, and a mixing part (109) mixes the first and second correction signals at the mixing ratio.SELECTED DRAWING: Figure 1
