An imaging device, an imaging method, and the like suppress a decrease in resolution relative to the captured image while relatively enlarging a first processing area as compared with a second processing area. The imaging device includes an image sensor (240) that includes a plurality of pixels that generate an image signal from an object image that is formed by an imaging optical system, a scaling section (340) that performs a scaling process on an original image that includes image signals that correspond to the plurality of pixels, and an output section (350) that outputs an image after the scaling process as a scaled image, the scaling section (340) performing the scaling process using a different scaling factor corresponding to the position of a pixel of interest within the scaled image, and the image sensor (240) including pixels in a number larger than the number of pixels of the scaled image as the plurality of pixels.
