Abstract
An imaging apparatus includes an image sensor and a processor. The processor performs demosaicing processing on captured image data obtained by being imaged by the image sensor, acquires distance data representing a distance between the imaging apparatus and a subject for each of a plurality of pixels included in a captured image represented based on the captured image data, specifies a correction target pixel from among the plurality of pixels based on the distance data, and performs correction processing of correcting a false signal generated by the demosaicing processing, on correction target pixel data of the correction target pixel.
