An image capable of confirming a focus position is generated without superimposing a peaking signal on a captured image. Therefore, an image processing apparatus according to the present technology includes an image signal generation unit that generates a plurality of image signals having frequency characteristics different from each other from one captured image signal, and a blending processing unit that blends the plurality of image signals on the basis of a blend ratio determined on the basis of a peaking signal for the one captured image signal.

This invention enables one to check flicker of a HFR image signal. A display image signal of a first frame rate for flicker check is obtained on the basis of an image signal of a second frame rate. For example, the display image signal of the first frame rate is generated from the image signal of the second frame rate by a frame thinning process. In this case, a frame to be thinned is determined from a relationship between the second frame rate and a light source frequency. For example, the number of frames to be a flicker period is obtained from the second frame rate and the light source frequency, and the frame to be thinned is determined so that continuous frames of the number of frames to be the flicker period are present.
