An image processing apparatus for processing an image signal includes an integrator configured to acquire the image signal during each detection period having a length equal to or longer than one cycle of flicker occurring on an image under illumination of a fluorescent lamp, and to integrate the acquired image signal in a unit of time equal to one horizontal synchronization period or longer; and a flicker detector configured to estimate a flicker component on the basis of a frequency analysis result obtained in the unit of each detection period by using an integral result obtained by the integrator.
