PROBLEM TO BE SOLVED: To provide a focus detection device with which it is possible to defect a focus with high accuracy without being affected by the color of light.SOLUTION: The focus detection device comprises: a phase difference detection unit for detecting a phase difference using a plurality of first pixels for outputting a pair of first signals corresponding to the luminous energy of a first color, a plurality of second pixels for outputting a pair of second signals corresponding to the luminous energy of a second color, and a phase difference in the pair of first signals, or the pair of second signals; and a defocus amount calculation unit for calculating a defocus amount using a first coefficient corresponding to the first color when the phase difference is detected using the pair of first signals, and calculating a defocus amount using a second coefficient corresponding to the second color when the phase difference is detected using the pair of second signals.SELECTED DRAWING: Figure 15 |
